The history of automotive production is littered with the fallen badges of car companies that shone brightly but fell by the wayside in the face of competition from the industry’s giants. Whether you pine for an AMC, a Studebaker, or a Saab, it’s a Ford or a Honda you’ll be driving in 2019.
In the world of electric cars it has been a slightly different story. Though the big names have dipped a toe in the water they have been usurped by a genuinely disruptive contender. If you drive an electric car in 2019 it won’t be that Ford or Honda, it could be a Nissan, but by far the dominant name in EV right now is Tesla.
Motor vehicles are standing at the brink of a generational shift from internal combustion to electric drive. Will Tesla become the giant it hopes, or will history repeat itself?

Here at Hackaday, we love knobs and buttons. So what could be better than one button? How about 16! No deep philosophy about the true nature of Making here; [infovore], [tehn], and [shellfritsch] put together a very slick, very adaptable bank of 16 analog faders for controlling music synthesis. If you don’t recognize those names it might help to mention that [tehn] is one of the folks behind monome, a company built on their iconic grid controller. Monome now produces a variety of lovingly crafted music creation tools.
Over the years we’ve written about some of the many clones and DIY versions of the monome grid controller, so it’s exciting to see an open source hardware release by the creators themselves!
The unambiguously named 16n follows in the footsteps of the monome grid in the sense that it’s not really for something specific. The grid is a musical instrument insofar as it can be connected to a computer (or a modular synth, etc) and used as a control input for another tool that creates sound. Likewise, the 16n is designed to be easily integrated into a music creation workflow. It can speak a variety of interfaces, like purely analog control voltage (it has one jack per fader), or i2c to connect to certain other monome devices like Ansible and Teletype. Under the hood, the 16n is actually a Teensy, so it’s fluent in MIDI over USB and nearly anything else you can imagine.

If you think that this scratch instrument looks as though it should be at least… three times larger in order to be useful, you’d be wrong. This mighty pocket-sized instrument can really get the club hopping despite its diminuitive size. Despite that, the quality of the build as well as its use of off-the-shelf components for almost every part means that if you need a small, portable turntable there’s finally one you can build on your own.
[rasteri] built the SC1000 digital scratch instrument as a member of the portabilist scene, focusing on downsizing the equipment needed for a proper DJ setup. This instrument uses as Olimex A13-SOM-256 system-on-module, an ARM microprocessor, and can use a USB stick in order to load beats to the system. The scratch wheel itself uses a magnetic rotary encoder to sense position, and the slider is miniaturized as well.
If you want to learn to scratch good and learn to do other things good too, there’s a demo below showing a demonstration of the instrument, as well as a how-to video on the project page. All of the build files and software are open-source, so it won’t be too difficult to get one for yourself as long as you have some experience printing PCBs. If you need the rest of the equipment for a DJ booth, of course that’s also something you can build.

Bad Obsession Motorsport have been stuffing the engine and suspension from a 4WD Celica into an old Mini since forever. It is a wonderful homage to Police Squad and some of the best machining and fabrication you’ll see on YouTube. The latest episode tackled the electrical system and how to drive an alternator in an extremely cramped engine bay. The solution was a strange flex-shaft confabulation, and now the Bad Obsession Motorsport guys have a video on how they attached an alternator to a car where no alternator should go. It’s forty minutes of machining, go watch it.
Last Friday was Black Friday, and that means it’s time to CONSUME CONSUME CONSUME. Tindie’s having a sale right now, so check that out.
I’m the future of autonomous flight! This week, I got a market research survey in my email from Uber, wanting me to give my thoughts on autonomous ridesharing VTOL aircraft. Uber’s current plan for ridesharing small aircraft involves buying whatever Embraer comes up with (Uber is not developing their own aircraft), not having pilots (this will never get past the FAA), and turning a random parking lot in LA into the busiest airport in the world (by aircraft movements, which again is something that will never get past the FAA). Needless to say, this is criminally dumb, and I’m more than happy to give my thoughts. Below are the relevant screencaps of the survey:
The crux of this survey is basic market research; how much would I pay for a VTOL ride sharing service versus buying a new (autonomous) car versus using an autonomous Uber. You’ve also got a Likert scale thingy asking me if I’m comfortable flying in a battery-powered aircraft. Protip: I highly doubt anyone given this survey has flown in a battery-powered aircraft. Proprotip: the easiest way to screw up the scoring for a Likert scale is to answer ‘1’ for the first question, ‘2’ for the second, etc., and wrap back around to ‘1’ for the sixth question.
Don’t worry, though: I answered all the questions truthfully, but Uber Air will never happen. The FAA won’t let this one fly, and no company will ever carry passengers without a licensed pilot on board.
We can certainly relate to an incomplete project sowing the seed for a better one, and that’s just what happened in [JohnnyQ90]’s latest video. He initially set out to create an air compressor powered by a nitro engine, and partially succeeded – air was compressed, but not nearly enough to be useful.
Instead, he changed tack and decided to use the 1 cc engine to make a small electric generator. [JohnnyQ90] is, of course, no stranger to the nitro engine, having previously brought us the micro chainsaw conversion, and nitro powered rotary tool. This time round, the build is a conceptually simple task: connect an engine to a DC motor and you’re done. But physically implementing it in an elegant way is a different story, and this is always where [JohnnyQ90] shines; we never get tired of watching him produce precision parts on the lathe. A fuel tank is made from a modified Zippo can and, courtesy of a CNC milled fan and 3D printed shroud, the motor air cools itself.
Towards the end of the video, [JohnnyQ90] plays with the throttle a little, causing the bulb connected to the generator to brighten accordingly. It might be fun to control the throttle with a servo and try to regulate the voltage on the output under different load conditions.
We love novel ways of creating electricity; previously we’ve written about how to generate power from a coke can, as well as this 120 W thermoelectric generator (TEG) setup.

On the day mini-amps were invented, electric guitar players the world over rejoiced. No longer would they be house-bound when jamming out on their favourite guitar. It is a doubly wondrous day indeed when an electric guitar-inclined maker realizes they can make their own.
[Frank Olson Music] took apart an old pair of headphones and salvaged the speakers — perhaps intending to replicate a vintage sound — and set them aside. Relying on the incisive application of an X-Acto knife, [Olson] made swift work cutting some basswood planks into pieces of the amp before gluing them together — sizing it to be only just bigger than the speakers. A tie was also shown no mercy and used as a dapper grille screen. Both the head and speaker cabinets were sanded and stained for a matching finish.

There’s building small computers — like the Raspberry Pi — and then there’s building small computers — like this Desktop Viewer from Star Trek.
[Monta Elkins] is using a Beetle for this project; it’s an Arduino clone, hosting the ATMega32U4 microcontroller, with a unique feature that allows you to twist connecting wires to secure them to the board. Instead, [Elkins] went with the logical choice of soldering them. For a display, he used a SPI serial OLED 128 x 64 monochrome screen which he has cycling through a number of iconic Star Trek TOS symbols and animations. The images were converted into PROGMEM — which gets loaded into flash memory — before finally being uploaded to the Beetle.
Following some fine 3D print work in ABS plastic which rendered the Desktop Viewer’s case, [Elkins] used acetone to solvent-weld the pieces together and applied a quick coat of paint to finish it off. This little replica would make a great desktop gadget as it requires a micro-USB to power the device.
