From the humble Atari game system to the high-powered consoles we have today, advancements in technology have truly transformed the way we play games. We are no longer limited to a single-player experience, as gaming has made users more connected than ever before. This has opened up a world of possibilities for the industry that keeps coming out with novel innovations.
Read on for the four trends that we think will change the future of online gaming as we know it.
Since the cryptocurrency boom, blockchain technology has gained mainstream recognition. It has been applied to a variety of things – from ticketing to inventory control. This technology solves many of the current security woes brought about by decentralizing data, storing it in different blocks distributed across a network of computers. This way, it removes the risk of a single point of failure and makes the manipulation of data near impossible. As the technology is improved and adapted, virtual items continue to carry more real-world value. It makes sense that gaming companies have started integrating blockchain technology, with some games built around this specific concept. For instance, the New York Times reports that a CryptoKitties players, a game that deals solely in the collection of virtual kittens, managed to sell one of their CryptoKitties for a whopping $140,000. Future applications could include using this technology to facilitate secure in-game payments and purchases.
Lastly, augmented reality (AR) has seen an uptick in the last couple of years mainly due to the success of Pokémon Go. While it was initially seen as a fad, it quickly became a worldwide phenomenon. Pokémon Go has been downloaded over 800 million times resulting in around $2 billion in revenue. Because of the game’s success, a slew of AR features followed on games such as Harry Potter: Wizards Unite and Minecraft Earth. With the 5G-technology rollout, AR gaming is set to get even bigger thanks to the increased bandwidth and speed gamers will have access to.
It’s no secret I’m a huge fan of Warner Brothers cartoons. My sister and I were basically raised on this stuff, and so much of our cultural reference points (and humor) comes from watching Bugs Bunny when we were growing up.
So, as Halloween approached, I thought it might be cool to recreate an iconic image from the 1952 cartoon “Water Water Every Hare”, where Bugs is taken to a big scary castle on the edge of a waterfall. The castle is inhabited by, naturally, an Evil Scientist, who advertises the fact with a blinking sign on the towers of his castle.
Okay, I’m not really a scientist, I’m an engineer, but I figure I could apply a little artistic license and make a sign like that for my house for Halloween.
I wanted it big enough so I could put it in an upstairs window and have it visible from the pathway. We get a LOT of kids through our community over Halloween, and tons of parents as well (since mostly the parents would get the reference), so it needed to be visible. In order to constrain the glare, I decided to put it in basically a shadowbox configuration. An enclosed box, LED lighting inside, with a cutout pattern on front that would show the text.
First step was to use the laser cutter at the Makerspace to cut out the lettering. As anyone who does stencils will recognize, the second line (“BOO”) would have floating elements in it, and would have to be glued down after the box was made.
I found some old acrylic sheeting that still had one strip of white backing on that, and that made a dandy diffuser, as well as a place to mount the center parts of the lettering.
Next, based on the size of the lettering, I whipped up a box out of some scrap wood, and painted it black. I also painted the letter stencils so the shadowmask wouldn’t show up at night, but the lettering shining through would.
The colored lighting was done with some LED strips and an arduino. The sketch was painfully simple. Just first row on, wait a second, off, wait a half second, second row on, wait a half second, off, then wait a half second and then repeat. The most challenging part was soldering up the strips (I needed 3 rows), and mounting the arduino.
The only thing I had to go ‘buy’ was the backing board. A quick trip to Michaels got me a sheet of the plastic corrugated ‘cardboard’ for $4. This stuff is awesome, and I think I’m going to use it more in future projects. I mounted the LED strips and the arduino to it initially using hot glue, but while that’s the default ‘go to’ for DIY projects, I ended up ziptying the strips to the backing board, and doing the same for the arduino. Since the board is flexible, hot glue just didn’t make sense.
Once everything was screwed together, it was just a matter of putting it in the window and plugging it in. Yay! It worked!
I slightly misjudged the width of the window, so it doesn’t quite have the margins I had hoped, but when it got dark, it looked great. Very happy with the end result!
This past weekend I finally got to let TARS, my Tesla Model 3 Performance, stretch its legs a big and go for some long distance driving. Over 3 days, we covered almost 700 miles, from Boston, MA to Rochester, NY.
This drive is almost entirely interstate, with the absolutely mind numbing stretch of the NY Thruway between Syracuse and Rochester coming to mind as the most tedious part of the trip. I was looking forward to using Autopilot for that bit in particular, and I wasn’t disappointed.
My Model 3 is normally set to charge to 90%, which gets me about 270 miles of range. According to Tesla, this helps preserve the lifetime of the battery. But for short term trips, it’s okay to go into ‘trip mode’ – charge the battery to 100%. That brought my range up to about 307 miles. Golden!
The next step was to plan the trip a bit. With my battery topped up, the trip analyzer said that I could make it to the Utica, NY supercharger in one go. That’s about 270 miles, and I in theory would have 35 miles left when I get there. Now, I treat these estimators with a heavy dose of skepticism. There’s a lot of factors that impact battery consumption – a static analysis would have resulted in a lot of ‘Yeah, but what about…’ questions. However, this estimation was being done by the car, while I was driving it, with active traffic reports being reported in in realtime. It should be pretty accurate, we’ll see!
We rolled out around 2pm on Friday and immediately ran into unexpected traffic (later we learned from some friends that it wasn’t just us – all the routes headed west were problematic). TARS kept updating the route onto more and more secondary roads, to the point where I was expecting us to be routed through someone’s garage and down their garden paths. Hopefully I could avoid any empty swimming pools.
Finally, we got past the traffic and on the open road. The car settled into the traffic fine, and I was able to enable autopilot for a large part of the rest of the trip.
There’s an awful lot of jawing going on about the Tesla Autopilot. It’s not full self driving (FSD), no. It’s also not ‘just adaptive cruise control’ (as I’ve heard others yammer). It’s somewhere in between. On an open highway, without much traffic, it’s dreamy. Lane changes, slowing down / speeding up according to traffic changes, dealing with people merging in or passing, it works well. The car software is updated often – anywhere from once a week to every few weeks. And each time a new version comes down, the autopilot gets better, smoother, and less janky.
Here’s a good example. When I received my car in May, it was just after the ‘automatically change lanes’ function was enabled. And it was sketchy AF. Yes, it would signal, change lanes, and continue. But the signal ranges were all goofy, and if there was someone anywhere near your blindspot, the car would sort of ‘stall’ – leaving the blinker on, waiting for the other car to move. If they backed off to let you in (like all nice New England drivers do, right?), the autopilot wouldn’t pick up on the situation change fast enough, so would just sit there with the blinker on. Naturally, the other driver would speed up thinking I wasn’t changing lanes, and then Autopilot would decide there was a threat, and ‘phantom brake’ or jog back into lane. it was unnerving.
With the current version (v32.12.1 – one patch level beyond the v10 release), this process is FAR smoother. I was comfortable letting the car decide when to change lanes to get around slower traffic, or move over to let other cars by.
Interstate changes and ramps were still a little off. When the car does not have clear lines on the road on ramps (which tend to be wider than normal highway lanes), it tends to disconcertingly head toward the outside of the ramp until it’s close to a line, then sort of jog back. It’s jarring and uncomfortable, but it will do it. I let TARS make 2-3 highway changes for me, keeping my hands and brake-foot ready for a sudden takeover.
First Recharging Stop
Eventually we made it to Utica, and pulled into the charging station. At this point, the display was showing we had about 20 miles of battery range left. I had been watching the numbers the entire drive, and even with the traffic, rain, etc, the numbers really didn’t change much. The computer had the advantage of having access to traffic, weather, temperature, and route information, as well as how my batteries were behaving. It didn’t get it wrong.
We jacked into the supercharger and got the message “20 minutes until you can continue your trip” – Huh! 4+ hours of driving, and a recharge in 20 minutes? I’m good with that. Lets grab dinner.
So we walked to the local food joint and had a quick meal while the car recharged.
Getting back in, we were at something like 240 miles of range, plenty of electrons to get us the last 2 hours to Rochester.
We ended up going to our friends house first, then to the hotel, which left us with about 90 miles of range. Plenty for the next day, but we should top it up at some point.
On Saturday, we topped up the car with a very fast stop at the local supercharger (20m on the charger), which got us back up to about 200 miles. This is where I start having some questions.
It looks like not all superchargers are the same. Some have very good high speed charging (500+ miles per hour charging speed), others are lower. It’s not because there’s more cars at the charging station or anything, the level of power coming from each station just seems to vary. This is disconcerting, because when you’re trip planning, some stations may be able to charge your car up to full trip-level charge in 40 minutes, others may take an hour and change. Now, the charging ‘curve’ for a Tesla isn’t flat. To go from 0-75% charge can take as long as it takes to go from 75% to 100%. If you’re doing long distance driving, the time it takes to top up gets important. The station near the hotel was not charging as fast as the one in Utica. That was concerning, because we should be able to fill up before we drove home on Sunday. Timing would be important.
At the end of weekend, we did the happy party trick of showing off Enhanced Summon in a crowded private parking lot (there were half a dozen cars in our friends driveway, and rock walls all around. I walked a hundred feet away and did a “HOLD MY BEER” by summoning TARS to me. It did it BEAUTIFULLY. The summon feature has improved greatly in two or three weeks it’s been out. Very smooth, and doing exactly what a human would have done to back up, move the car forward and back 2-3 times to line it up with the exit, then roll over to where I stood.
It’s a great trick to impress your friends with. I asked our host “So, getting a Tesla now?” and he, a normally very conservative skeptical person, answered “I hadn’t thought about it before, but now I’m seriously considering it. I’m very impressed.”
We headed out to the charging station I had used on Saturday, and had the same rate problem I saw before. So it wasn’t load or anything, it was just that this station sucked. We went for a walk in the local mall, and decided to head out. The mapping system set our next recharge in Lee, MA, about 270 miles away. We should arrive with 20-30 miles of charge left. So off we went.
The drive back was uneventful, with autopilot doing it’s thing for most of the drive. Oddly, my biggest issue was I rest my hand on the steering wheel giving it a little ‘tension’ to let the car know I’m there. After 20 minutes of leaving my hand in one spot, it would get tired and sweaty, and I had to switch hands. Talk about first world problems!
We got to Lee and plugged in, and YAY! Plenty of high speed charging! What a relief. We were able to top up the battery enough to get home in under 15 minutes, and we got home to a dog that was extremely happy to see us after such a long time away (Yes, we had people taking care of her, don’t be like that. But she did miss us).
All in all, the road trip was everything I expected it to be. Smooth, fast, comfortable, and best of all, 100% electric. Assuming our chargers were getting elecricity from standard sources, we produced 1/3rd as much carbon as we would have in a normal gas car. I personally buy my electricity from a wind farm, so at least 1/3 of the trip was from renewables, so that reduced our footprint even further.
Someone asked me from a cost perspective, was it cheaper driving an all electric car? I found an article that summed it up like this:
The long-range version of the Model 3 has a 75 kWh battery pack with a 310 mile range. If we still assume the average national electric pricing of 13 cents per kWh and a charging efficiency of 85%, then a full charge will cost $11.47. This is $3.70 per 100 miles of mixed city and freeway driving, or 3.7 cents per mile. This is almost 80% less than the cost per mile to drive the most popular gas-powered cars, which is approximately 20 cents per mile.
This fits my back of the envelope fiddling. I looked at my bill, and the entire charging costs from Sunday’s drive (about 370 miles) was $11.47. So not only was it not putting out any CO2, it was far far less expensive to operate than a traditional car.
I can easily see a future where more and more of these trips are automated, and my input into operating the car will be needed less and less. We’re not there yet, and we won’t be for I’m guessing another 3-5 years. But the progress is absolutely there, and I welcome it.
Woodworking. Okay, great, another rabbit hole to go down, right? Well, sorta. Over the years I’ve learned to knock things together, how to saw, hammer, screw, paint, and assemble things out of wood, but I never really understood finishing. How to shape something creatively and come up with something beautiful at the end.
About a year ago I took a class up at Makeit Labs on the wood lathe. Lathes have always been fascinating to me, like potters wheels for wood. Take a primal material, spin it, and (in the case of a lathe) by removing material, shape it into something beautiful and smooth.
The class was great, and I learned the basics of turning. How to use a gouge, how to set up the spindles, and probably most importantly, what not to do to protect both myself and the equipment. I did a little turning after that and made a small parts holder for my work bench, but life stuff got in the way, and I didn’t do much else for a while.
A few weeks ago things were shifting back to slight normalcy in my life, and I found myself with a few hours of free time up at the lab. When I first took the lathe course, I bought a box of sugar maple blanks, about 4″ wide and 5″ long. Maple is hard wood, but can be turned pretty easily. I decided to try and make a type of cup I’d like to use for hand lathered shaving cream. So it needed to be wide enough for the brush and also relatively waterproof. (Turns out after I did the shaping, the size I was using was too small, and making wood ‘waterproof’ is actually pretty hard, so this ended up just being a sample / test piece.)
The initial work took about 2 hours to get the shape down to what I wanted. It’s funny. Woodworkers learn this pretty fast, but it takes a while to sink in. The turning / shaping part of the process is the most rewarding and creative, but is the easiest / shortest part of the entire process. I could carve wood like this for hours, but I’d end up with a bunch of carved unfinished pieces. That’s not what I wanted to learn this time around, I wanted to take it to completion. So after the shaping was done, I took the piece home to start the finishing process
First of all, it needed to be stained. Some Minwax cherry stain was acquired. I took a sheet of 220 grit sandpaper to the entire piece, and sanded it smooth inside and out. Learning how to sand the inside of a cup without gouging it is a bit of a challenge, particularly when the opening is only 3″ across or so, but I was able to get it pretty smooth.
After putting on a set of latex gloves (this part I knew. Stain stains EVERYTHING – including hands!), I brushed on on the first stain, and the color jumped right out at me. Hey, I can see the grain! The instructions said I should smooth the stain on, let it sit for 15-20 minutes, then wipe off the excess. I did that, and the result was… good. Not earthshattering, but it was a mark above just a raw wood piece. I began to see problems working with a piece that was this shape… the stain tends to settle on places that were more horizontal, so the base had a darker look than the sides. I resolved on the next layer to make sure the areas that had less color would get more coverage.
After a light sanding to help remove the excess on the flat areas, I stained it again, and the color was better, but still relatively dull. I mean, yeah, I can hear folks going “Duh, you’re not done yet” but I was hoping for a little glow from the coloring. Nope, not quite yet.
The last step was to put a few layers of polyurethane on. Now, this is a tricky topic, and I suspect major fistfights have broken out about how to this properly, what materials to use, etc. As this was my first piece, and I’m hoping to make things more water resistant in the future, I chose an oil-based clear poly coat. This should make it ‘okay’ for this to get wet, but I wouldn’t want for it to be holding buckets of water on a regular basis.
Poly cures slow, so I put on a single coat, waited until it had cured (about a day), sanded it with 220, wiped it clean, and put another coat on. The result is… good. I like it. It has a healthy glow and shine to it, and I can say “See this? I made this.”
So now what? I’m going to check around about how to do final polish / finish. Do I sand and buff the poly coat one more time? I think yes, but I need to check. Even if I stop now, I can put this on my shelf and go “I like this. I made it.”
I’ve since picked up a lathe I can use at home to do my own turning, so the next project hopefully will be entirely homegrown. Stay tuned!
The past 6 months have been quite the whirlwind. I’m sure I don’t need to do the rundown, most of ya’ll know what’s been going on, but I have to say, today is one of the first days in a long time where I feel things are settling back to normalcy.
I’m sitting in my living room listening to piano music on Spotify, my dog is happily snoozing on the couch next to me, my family is out of the house – one is at school, the other is out visiting a friend. The summer weather heat has broken and I’m able to sit in my space, doing my job, and just… relax.
I finally got it. I got the robotic, electric, high performance car of my dreams. Sleek, fast, geeky as all get out, tremendous range – it’s everything a nerd would want in a car.
But it’s not perfect.
People have been coming to me pretty regularly and saying “So, how do you like your Tesla?” – and I answer truthfully. “I love it. It’s amazing. It’s my robotic space car. It’s nerdy and stupendously fast. But it’s not without its faults.” At this point their eyes light up and they get excited. “Yeah? Like what?!?”
The automotive press has not been kind to Tesla. With a strongly outspoken CEO in Elon Musk, it’s lofty goal of bringing affordable, exciting electric cars to the masses, and the base challenge of pushing against an industry selling a few hundred billion dollars worth of cars every year, it hasn’t been easy for them to break into the market and succeed. But succeed they have, pretty much jumpstarting the performance / luxury electric car market singlehandedly.
But there are problems. The car is hardly perfect. I’d like to run down the flaws and issues as I see them…
Tesla the company is relatively new in the automotive industry. Founded in 2003 right after the dot com bubble burst, they spent some years understanding what it takes to build a new kind of car from the ground up, without carrying all the folderol that the big auto manufacturers have. The Roadster came out in 2008, and the Model S 4 years later in 2012. In that time, the focus had to be on technology, manufacturing, and production.
What they didn’t have a chance to focus on was the customer end of things.
Dealing with Tesla can be an infuriating process. Because they don’t have a ‘dealer’ model similar to current car manufacturers, buying a Tesla is not far from ordering a laptop from Apple. You got to the website, choose your option, click ‘Buy’, and a car will be available… sometime.
It’s this ‘sometime’ can be problematic. Without a salesperson to regularly work with, the delivery process is extremely oblique. There is a nice website that will tell you the status on your car, but it’s not particularly informative, showing things like “We’re putting together your paperwork” for WEEKS until it suddenly changes to “Your car will be available for pickup in 3 days at such and such a location.” Thanks guys.
The Delivery Process
Okay, so now you have a delivery date. What happens at the delivery is relatively normal. You show up at the ‘delivery center’, 1-2 folks walk you through the dos and donts of the car, you sign a bunch of papers, and you drive off in the car. This actually went fine, the only drawback is the people there are complete strangers. No one knew me or anything about my excitement or interest or history. They were basically just like a refrigerator installer. “Here’s yer machine, bud. Seeya.”
I have a Model 3 Performance, which has some nice trim changes, but in general, the Model 3 is BORING. It’s a 4 door sedan. I suppose this is better than some of the more radical car designs floating around (Have you seen the new Civics and Prius’s? Yikes.) But on the other hand, if I’m getting a fairly expensive car, I wouldn’t mind if it turned heads just a little. People who know Teslas will go “Hey! Look! A Tesla!” but for the most part, the Model 3 just blends in with the other shiny sedans out there.
Having said that, there are some Issues – well known, easy to work around, and possibly even understandable for a ‘first generation’ run of this model, but they’re still there:
The delivery person warned us of this, but I did it before he even told me. There’s a nice little hatch that opens and closes over the charging port. You can unlock this hatch from the mobile app or from inside the car, or by touching the bottom of it when you want to plug in the cable. BUT. You should never try to close it by hand. Nope nope. Don’t push on the top of it or move the door, that can break it.
The storage space under the front hood (where an ICE car would have an engine) is referred to as the ‘Frunk’. Apparently, this thing is delicate as heck. The delivery guy went out of his way to tell me to never slam it, nor close it with one hand. Gently set the hood down onto the latch, and then push down with both hands on either side of the latch. This seems like an obvious workaround to a design error, but it’s not something a normal person would think to do.
Much has been said about trim and panel fit. Sometimes the cars don’t fit together cleanly and properly. This was a real problem in the first runs of the Model 3, but far less so in later ones. I received mine in the spring of 2019, and haven’t noticed any particular gaps or bends or points where things aren’t coming together. Having said that, there has been a persistent whistling noise coming from the drivers side mirror. If I stick my hand out while driving, I can make that sound stop, but it’s obvious there’s some gap in the trim that’s causing air to whistle through it.
The interior of the car is beautifully simplistic. Comfortable, laid out well, lit well, and easily the most comfortable car I’ve ever owned. The expansive glass roof, plenty of headroom, very adjustable and supportive seats, and the well articulated steering wheel all help make the car extremely comfortable.
But, this article isn’t “everything that’s awesome” – lets look at some of the flaws.
I absolutely detest the door lock mechanism. For those who have not been in a Model 3, there isn’t an actual ‘door latch’ that you pull to open the door. There’s a button. You touch the button, the window slides down about an inch, and the door unlatches – and then you push it open. There’s a sort of emergency latch that you can pull up, but the Tesla rep warned me never to use it, as it might damage the door. This just seems like poor design or an afterthought. It’s taken some time to get used to the ‘push button to open the door’ methodology – I almost never get confused now, but it’s really a very bad choice of design.
The center console is a mess. There’s several chambers, each quite deep and having a different ‘lift’ or ’tilt’ mechanism. They’re also cavernously deep, so putting something in them is akin to dropping the one ring into Mt Doom. You will likely not get it back easily.
No drink holders in the back? Well, they are sort of there, but they’re in the center console between the back seats. That’s… sort of weird, particularly if people are sitting 3 across.
It took looking up in the manual to figure out where the emergency 4 way blinker lights are. I’ll leave it as an exercise for the reader to try and find the control next time they’re in a Model 3. We couldn’t find it until we looked it up in the manual. This is an EMERGENCY BLINKER button. It should be trivial to locate. It isn’t.
Why doesn’t the front drink holder have removable silicon liners? Those things get DIRTY. Even inexpensive little toyotas and kias have silicone liners for the cup holders.
Okay, lets start talking about the controls. This section isn’t about the software that runs the center display / functions of the car, this is basic control layout and usage.
The Model 3 has a very simplified set of operator controls. The steering wheel (obviously) two foot pedals, two control stalks (one on each side), and two thumwheel / joysticks. And the horn. That’s it. Everything else is done via the touchscreen. But lets look at those controls.
The stalks are useful and well placed, as are the thumbwheels. I never lose track of where they are. And there were some logical decisions made about what each set does. The left thumbwheel is ONLY audio controls (volume up/down, next/previous track, pause and unpause). The right thumbwheel is for quick commands to the autopilot / cruise control system. Pretty easy to work with.
The stalks are more complicated, because they service multiple purposes. The left one is your turn blinker, obviously. It also controls your high and low beams for the headlights, as well as a ‘quick touch’ to turn the windshield wipers on and off (assuming the auto wiper system doesn’t work).
The right stalk is sort of like your gear shift. You control what ‘gear’ you’re in (drive, reverse, park), as well as the state of the autopilot system. I haven’t figured out a lot of the wiggle functions on that stalk, other than engage autopilot and ‘go into drive’.
Sounds basic, so what’s are the issues? Well, there’s a bunch:
First, the mechanism for turning on and off turn signals is confusing. A light push on the left stalk, up or down, will blink the turn signals 3 times. If you hold the stalk, they’ll keep blinking until you release it. There’s a ‘secondary’ level of push though, that means “turn the turn signal on until… something tells them to stop.” – this part is the confusing one. The turn signals will stop blinking if the car thinks you’ve completed a turn, or… you signal some other way. How to turn off a turn signal seems to involve some invocation I still haven’t worked out. I find myself signaling in the opposite direction sometimes, or just wiggling the stalk around until the signals stop. This is hardly safe communication with other drives. On a normal car, the turn signal stalk locks into position until it either is automatically returned to a neutral spot, or you force it back to the center. The Tesla turn stalk doesn’t do that. It is always in the ‘neutral’ position whether you’re signalling or not. This is confusing.
Second, you can only sort of control your wipers via the end button push. A quick push will wipe your wipers once, and a longer push will turn on the spritzers. The wipers are normally controlled via the center touchscreen (with intermittency and automatic settings controlled there). But there’s numerous times i find the ‘automatic wipers’ don’t really keep the windshield clear enough, so i find myself pushing the button a lot. Or navigating the touchscreen to turn the wipers on and off faster or slower. You don’t want to be fiddling with the touchscreen while driving. This is not a very good setup.
High and low beam headlights work as you’d expect, though the ‘automatic’ high beams is gimmicky and works poorly. More on that in the Software section below.
Oddly, the right stalk is mostly okay. the gear position mechanism makes sense, and the ‘double press’ to engage autopilot is intuitive and works well.
I’m going to lump a couple topics into this section, but first some preamble.
So much of what makes a Tesla a remarkable vehicle is the decision to base as much of it’s functionality as possible around software. This is why there’s only one display system (the touch screen), and virtually every function is managed and displayed through this interface. It makes it easy to change, easy to upgrade, and easy to tune. All the ‘smarts’ of the car (it’s sensors, battery management, and yes, even the power train) are controlled via software. Some of that software is visible to the operator directly, but a lot of is internal. The operator doesn’t see the battery management, the heating / cooling systems, the adaptive drive for the motors, etc. The operator mostly sees the interface on the display. So lets focus on that.
The Tesla Model 3 has one large 15″ LCD touchscreen in the middle of the dash. There are no other display systems in the car. No turn signals, no idiot lights, no dashboard. Just this display. This ‘one screen to rule them all’ makes the Tesla much easier to upgrade and modify. In a traditional car, you can’t move the heater control from one place to another because, after 6 months of use, you realize the original placement was poor. But on a single screen like this, it’s a simple software change to rearrange controls. This has disadvantages as well. The center location of the display is awkward for the standard driver who expects basic operational information to be directly in front of them. The speedometer is in the upper left corner of the screen, as are basic status lights like blinkers, hi/lobeams, and what gear you’re in. All other controls and information is located at different points of the screen ,and sometimes that info may be hidden or on a different tab. This absolutely takes time to get used to, but it means improvements can be made via software. By comparison, my Chevy Volt had the WORST design ever for it’s center console, with horribly placed buttons that were impossible to understand. The software interface on the touch screen was mediocre at best, and over the 3.5 years I had the car, they made absolutely zero UI improvements to that display, when any number of changes could have been made – just not to the button layout.
But enough background. Given this amazing technology, the interface and tools must be awesome and perfect, right? Oh hell no. Lets investigate…
There’s a system in the Tesla that allows the hi/lo beams for the headlights to automatically adjust based on oncoming traffic and other cars. On the surface, this seems pretty straightforward, and it works relatively well. Until it doesn’t. Hi/Lo beams are also a mechanism most drivers use to communicate with other drivers. “Your lights are off” “Something dangerous is ahead” “I’m a jerk”. The Tesla software will turn the hibeams on and off depending purely on distance to another car in front of it (if it sees it), and if another car is coming towards you. That’s it. On the highway, the highbeams can flicker up and down automatically several times in a minute depending on how far behind another car you are. This is irritating as heck for other drivers. While a nifty gimmick, I disabled it.
The windshield wiper automatic system is supposed to turn on the wipers when it starts raining, turn them to ‘fast’ when needed, and off when things are dry again. I find myself many times going “Why aren’t my wipers on?” The system is very cautious about when to turn them on. Once they’re on, they’re fine, and will turn themselves off after the rain stops, but I do find myself hitting the ‘wipe now’ button regularly because the automatic system hasn’t yet figured out the window is wet.
For some, this is it. The holy grail of the Tesla. The much vaunted ability for the car to drive itself. The model 3 has 8 external cameras that can ‘see’ to a distance of about 250meters. In addition to the cameras, there’s also a front facing radar that gives very accurate distance measurements to the computer. These systems together provide the autopilot computer in the car enough information for the car to drive itself. It can see obstacles, react to changing circumstances and environments, and navigate it’s way in relatively complex situations. It couples that information with maps that are constantly updated with traffic and construction changes. The car’s GPS will locate you on the map (though the Tesla won’t use GPS for very high detail information. You don’t want to depend on GPS for autopilot, then go into a tunnel, for example).
So, given all this technology, is it actually dependable as a self-driving system?
The autopilot has many many problems. It’s definitely not ready for prime time. While it is an absolute technological marvel, it is nowhere near the level needed for full autonomy. Even in the best possible driving situations for autonomous navigation (a mostly open highway), the system makes many many errors in judgement. Most of the time those errors are not threatening or dangerous, they’re just uncomfortable or irritating. A few examples:
The autopilot can change lanes as needed for faster / slower traffic or when approaching an exit. If there’s any form of traffic in the way (someone coming up quickly behind you, or a crowded lane), it’s handling of the lane change is infuriating. Not for me the driver, but mostly for other people on the road. It takes far far too long to make the decision to change lanes – and by the time it does, the ‘gap’ it was shooting for doesn’t exist anymore, so the car can swerve back into its original lane. Again, not particularly dangerous for me the driver, but irritating and alarming for people around us.
There are regular ‘phantom braking’ problems. You could be going along normally, and suddenly the car will ‘brake’ abruptly for no apparent reason. A moment later it’ll resume normal speed. This is jarring. I’m sure it had a very good reason to do that, but there’s no indication to the driver or passengers what just happened.
Autopilot HATES wide lanes. Onramps that don’t have middle dividing lines, or secondary roads that aren’t perfectly sized – the autopilot will ‘hunt’ from one side to another trying to guess which is the proper side of the road to be on. Ung.
The ‘navigate on autopilot’ feature which is supposed to allow the car to happily change from one highway to another using ramps without driver intervention gets easily confused on anything less than perfect interchanges. If the lane markings aren’t crystal clear and well sized, the car will jump around trying to determine the ‘best’ path on the ramps – and will frequently guess wrong.
The system is not ready. Having said that, Tesla is doing the right thing to get it there. Their software is constantly ‘learning’ how to drive properly – every Tesla on the road is collecting data on how people handle these weird road conditions, and that goes into the neural network that the navigation computer uses. And each update, it gets a little better. But I can’t see a driverless Tesla, or a ‘door to door automated driving’ Tesla on the road in the next 5 years.
So we’ve talked about basic software tools and functions in the car. In addition to those things, there’s some stuff that’s just plain goofy and fun to have. Since the Model 3 is basically a computer with a touch screen attached to a car, there’s some silly stuff you can do.
My question is, is this stuff really adding any value?
For instance. You can play games on the display. That’s sort of fun, and the display is good and uses the existing car controls to play the game. But that means you can only play in park. And from the drivers seat. This seems more of a ‘Hey kids, look what my car can do, neener!’ feature than something I can use as a selling point for the car.
Yeah, I have the Performance version of the model 3. That means the extra motor, the low profile wheels, the painted calipers, the whole shebang. Those extra options added another 25% to the base price of the car. What do I get for that? Well, to start there’s that neck-snapping 0-60 in 3.3 seconds acceleration. Driving a car with this much power, with an always-available 450HP and 470 ft-lbs of torque is intoxicating. It changes how you handle traffic, navigation, everything. That power is ALWAYS there. No downshifting, no revving / turbo spool up. This car is the modern day equivalent of Neal Stephenson’s Deliverator from Snow Crash:
“The Deliverator’s car has enough potential energy packed into its batteries to fire a pound of bacon into the asteroid Belt. Unlike a bimbo box or a Burb beater, the Deliverator’s car unloads that power through gaping, gleaming, polished sphincters. When the Deliverator puts the hammer down, shit happens. You want to talk contact patches? Your car’s tires have tiny contact patches, talk to the the asphalt in four places the size of your tongue. The Deliverator’s car has big sticky tires with contact patches the size of a fat lady’s thighs. The Deliverator is in touch with the road, starts like a bad day, stops on a peseta.”
But, the performance version has some drawbacks. The cost? I’m not sure if it’s worth it. Is it really necessary to have THAT much power at your beck and call at any minute? I don’t think so. The only time I’ve really used it is to impress people I take on test drives. That’s not worth the money.
But let’s also talk about those low profile wheels. The short version? They suck. They’re fragile as hell, and they are NOT covered under warranty. Yes, everyone ‘knows’ that low profile wheels are the worst thing to happen to cars since they added ‘tiptronic shifting’ to every hyundai on the planet, but at $750 a pop for those wheels, hitting a pothole gets real expensive, real fast. Ask me how I know.
A model 3 AWD Long Range will get you 0-60 in 4.5 seconds, for $12k less. Do yourself a favor. Unless you’re dripping money, if you want something that’s still faster than most cars out there, just get that.
So where does that leave me? Do I like my car? Yes. Am I excited everytime I get in it and drive? Definitely. Am I proud that I am using a vehicle that emits absolutely zero carbon dioxide, and I’m powering from energy I buy from wind farms and solar? Absolutely. Do I think this is the future of cars in the world? No question.
Is the car perfect? Absolutely not. Not even close.
But it is, by far, in my opinion, the best electric vehicle on the market today.
The year was 2005. The dotcom days were over, and even though the fear of Windows NT taking over the world was fading, Linux was still considered a “hacker” OS – something not to be taken seriously. Of course, the cool kids all knew that Linux was going to take over the world. Right? Right?
In May 2005, Nokia announced the N770 tablet. A full on tablet computer, with bluetooth, wireless, audio tools, all running Linux in a handheld configuration. While not the first portable handheld Linux device (my Sharp Zaurus SL5500 is an earlier example), the N770 grabbed my attention as something truly exciting. I wanted one in the worst way.
Alas, the reviews of the N770 were not kind. It was slow. It had very limited memory and storage. The battery life wasn’t so hot. I still wanted one, but couldn’t bring myself to fork over the couple hundred bucks to make it happen. Not 2 years later Apple released the iPhone, and the world of handheld computing was forever changed.
On the inside, the specs are interesting, but not particularly staggering:
I’ve always wanted to tinker with the N770, and at the last VCF-East (where I picked up my copy of Wizardry), a nice fellow gave me one that he wasn’t using. I was ecstatic. The device is much as I had read – small, lightweight, in a neat little aluminum shell it can slide out of. However, there was no power supply, so I couldn’t turn it on. Nokia devices in this generation (including the phones) used a very very small barrel connector for power. I didn’t have one of these. A quick ebay search and I found a power supply, and ordered it.
Two weeks later I had my power supply, and plugged in the N770… and… nothing really happened. After a few minutes, the Nokia logo would flash, then flash again, then flash again. My N770 was busted.
FINE, sez me. I had the fever, and nothing was going to stop me. eBay again! This time I waited a few days and ended up purchasing another N770 for $40 delivered. Take that!
THIS one arrived with a power supply, and in fairly decent shape (no stylus though – the first one I got did have one). I plugged it in, powered it up , and yay! It worked!
Okay, yeah. It’s slow. Connecting to wifi can take 2-3 minutes (!), and if you get the password wrong, you have to go through the process again.
The interface is… confusing. I understand it’s Maemo, which is a GUI on top of the linux core, and has been updated and modified a lot since then but there’s a lot of guesswork involved between the navigation buttons, the touchscreen controls, and the buttons on the top of the unit. It really feels like they didn’t quite know what to do with a tablet. Is it all touchscreen stuff? Or are there buttons and light keys, with the touchscreen stuff being tacked on as a ‘cool’ factor?
Nonetheless, its’ a cute little toy to play with, and I love having a working one as part of my collection.
The “Magic Mirror” craze got pretty big in the hacker community a few years ago. For those who may not be familiar with them, a Magic Mirror is setup using a small display behind a 2 way mirror to add text and information to your bathroom (or wherever) mirror. It’s pretty cool, and can be done at very low cost and with only a little bit of tech know-how.
I’ve always loved having ‘displays’ around my workspace – showing information that doesn’t need to sit on my ‘work’ monitors, but is handy to be able to glance at. Being able to quickly glance oer and see dashboards showing system status, or even something showing date, time, and the weather outside.
A few months ago I decided to take one of my spare monitors at home mounted on the wall over my desk and turn it into a permanent display. It would show my current calendar, weather, stock prices, stuff like that. I got to work.
This part is probably the easiest. I used a spare 24″ LCD monitor I had originally mounted to be a sort of TV display. It wasn’t showing anything yet, so I just co-opted it for the Mirror display. It had an HDMI port on it, so it was perfect.
The second component is a Raspberry Pi3 I had lying around from some other project. This particularly Pi is pretty old, so using it just drive a mostly static display seemed great. This one has a case and power supply. I was able to just stick it to the back of the monitor, coil up a HDMI cable next to it, and I was all set.
A small note here. A second display I built for our Makerspace actually uses the monitor itself to power the Pi, since the monitor had a USB port on it. A USB -> MicroUSB cable meant as soon as the monitor was powered up, the Pi would boot and start displaying information. Pretty handy.
When building up these systems, I highly recommend having a keyboard and mouse to plug into the Pi. You can use an ‘all in one’ wireless keyboard/mouse from Amazon – these are great because you don’t have to deal with the cables (particularly when the monitor is mounted on a wall), and you can just unplug the USB adapter and use the keyboard on another project at any time.
The needed packages are pretty straightforward:
Raspbian – the default Linux installation for the Raspberry Pi. Get this installed and up to date (Run the package manager updater after the install to make sure you have the latest and greatest of everything)
Using a command line or the package manager, make sure you have the following secondary tools installed (these are not installed by default):
Chromium (apt-get install chromium-browser)
Magic Mirror 2 – This is the core software that will run your display. Follow the directions on installation carefully. Clone the repository and get it ready for use. I use the manual installation procedure , it works best for how I build systems. YMMV.
Configuring the Host
At this point, I’m assuming the manual configuration of the software above has gone correctly, and you’re able to either use the Raspbian browser or Chromium to connect to http://localhost:8080/ on the Pi and view something approaching the display you want.
Now, this is where I’ve seen a lot of tutorials and other reference material fall down. How do you go from a desktop showing your display to something that will survive reboots, auto-configures itself, etc. Well, here’s what I did to make my display boards stable and rebootable without user intervention.
Some of these things are convenience items, some are mandatory.
For the love of all that is holy, set your password. The default ‘pi’ password is well known, please reset it. This device will be running unattended for days/weeks/months. Please change the password.
Rename the host – this is super handy so you can ssh to it easily. Edit the /etc/hostname file and give it a nice name (mine is ‘mirror’). Once you do this, from your local network, you’ll be able to ssh into the pi via ‘ssh firstname.lastname@example.org’ – neat trick, huh?
Create an autostartup script for the Pi that starts the browser in full screen mode just after the desktop loads. Best way to do this is to edit /etc/xdg/lxsession/LXDE-pi/autostart and put the following code in that file:
@xset s noblank
@xset s off
@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
@chromium-browser --app=http://localhost:8080 --start-fullscreen
Create a cron job entry that will cause the magic mirror server software to restart on reboot. Easiest way to do this is use the ‘crontab -e’ command to make a new entry. Add the following line to the bottom of file (note, this assumes that the Magic Mirror software is installed in /home/pi/MagicMirror – adjust if that’s not the case)
@reboot cd /home/pi/MagicMirror;node serveronly > /home/pi/nodeserver.log 2>&1
On reboot, your mirror software should come up cleanly. Here’s a small trick though that makes remote maintenance easy. If you make a change to the config of the server – add a new module, change sources, etc, and you’re like me and have long since detached the keyboard and house from the unit, this little command will force the Chromium browser to do a reload, bringing in the changes you make to your config file. No need to reboot!
DISPLAY=:0 xdotool key F5
Conclusions / Sum-up
I’ve been running my display at home, and the second display up at the lab for a few months now. I’ll write some more on a few of the modules I’ve used (hooking up to my home automation stuff has been interesting), but that’ll be in a future article. I love having the date, time, calendar, stock prices, and weather always visible. The news ticker at the bottom has been sort of ‘cute’, but I really don’t watch it that much.
There are literally hundreds of third party modules available for the mirror software. You can configure the layout of the screen to do just about anything – from showing phases of the moon to displaying the next time a bus will stop in front of your office. Enjoy!
In May, we adopted a beautiful little 8 year old beagle named Daisy.
We’d been haunting adoption / rescue organizations for several months, trying to find a dog that fit our needs. We were close to adopting a greyhound, but something at the last minute pushed us away. A lot had to do with our history with our last adoption… so we were very nervous about getting our next dog.
Daisy was the last unclaimed dog at an open adoption event down in Forever Home Rescue, in Medfield, MA. The folks there were surprised – it’s rare for a dog to not be adopted during their open houses. Daisy was extremely shy and best described as timid. Anytime she meets someone new she immediately goes down on her belly, and sort of ‘shoulder rolls’ over, putting her head on the ground, whining faintly. She wasn’t the bouncy happy dog that most places present for adoption, so when we arrived, we were concerned. “Is.. she okay?” Adopting an older dog is something we had considered, but we weren’t sure what it would like bringing in a new member of the house who has had a long and busy life before meeting us… would she be able to adapt to being with us?
But we took the plunge, and we’re so happy we did. Daisy has turned into a wonderful member of the family. Every day she gets more comfortable, more expressive, and more dog-like. She’s been with us two months, and in the last day or two, she’s started hopping up on the couch next to us without us needing to coax her or lift her up. She’s snuggling in next to us when she wants companionship, and is just being a great dog.
That’s not to say there haven’t been challenges. She came to us with some serious medical issues that required immediate surgery, several rounds of medication, and a lot of care just teaching her how to be a real dog. She’s definitely had several litters of pups, and her body shows she’s had some other rough times. But every day, she gets a little happier, a little more engaged… it’s been a great journey.
The migration of the blog off my friends shared environment (Thanks Allison!) is complete. Welcome to the new service!
NameCheap has been advertising their EasyWP hosting service for a while, and given it’s relatively inexpensive model ($3/mo-ish), and the fact that I was having a hard time figuring out how to get full SSL service on the blog, I figured the time was right.
This week is shutdown at work, so I’m technically on vacation. My wife and I have had several conversations about me shaving off my beard. It’s literally been 22 years since I had a cleanshaven face, I honestly wasn’t sure what I looked like – maybe vacation is a time to explore something new?
Welp, two days ago I took the plunge and shaved. It feels weird, and actually being able to feel air on my chin is pretty bizarre. I don’t think I’ll stick with this in the long run. Partly I’m just too lazy to keep shaved, but the bigger reason is I like my fuzzy face, and the cleanshaven look just doesn’t feel like me.
Many folks have said I look a lot like my dad… not so sure about that, but either way, it’s been a nice experience seeing my real face for once.
In 1982, I was a freshman at Rochester Institute of Technology. I had already been geeking out with Apple and TRS-80 computers through high school, and had enjoyed my share of games, but RIT was a whole new social crew, new computers, and new connections.
I wandered into one of the labs and met up with a group of gamers that would end up being my Crew for my time at RIT. One of the games they were most passionate about was Wizardry, from Sir-Tech Software, a Sword and Sorcery game that in many ways is the root of the “squad based” RPG games that became so popular. Instead of playing just one character, you controlled a group of 6 at a time, each with different skills and equipment.
The game was fantastic, and I became a huge fan, even writing a lame knock-off of my own called Explorer. (Interestingly, I got mail from a fellow named Rich Katz who apparently did some artwork on Explorer – I vaguely remember him from 1987. He has a great page up about it and the work he did. Thanks Rich!)
Anyway, a few weeks ago I was at the Vintage Computer Festival East down in Wall New Jersey. I have lots of good stories from it, but one particular exchange stands out.
Old sk00l software racks at #vcfeast – need a boxed Choplifter for your Apple ][+ ? C'mon down! We got it!
The VCF has mounds of software, still in boxes, they were trying to sell / get out of the warehouse. They set up an awesome ‘computer store’ with boxed copies of old software right there on the shelves. It was pretty awesome going through all the old still-boxed software. I noticed a set of boxes on a high shelf, and… yes! They were original copies of Wizardry! But it was for a later version. I wanted the first one, the one I played the most in high school. I spoke with one of the organizers for a while, and he said he’d check in the warehouse to see if there were any of the original boxes. I said I’d be happy to pay for them the next day.
Sunday rolled around, and I stopped over at the store. Sure enough, they had found a boxed copy of Wizardry 1, Proving Grounds of the Mad Overlord, and had put it aside for me. I was a proud owner of an original, still in box, copy of a game I played over 35 years ago.
No, I’m not going to try and use this disk, there are plenty of copies / versions on the internet. But having this box, with all the original documentation, and of course the master disk, and the cover artwork – it’s a great addition to my retro computing museum.
