Norbert Heinz, aka “HomoFaciens,” is no stranger to making versions of modern-day equipment in unusual ways, but what about the way that this equipment is actually powered? It’s not something that we normally consider if an AC adapter is nearby; you simply plug it into the wall and “free” power flows to your device.
Heinz’s project, however, runs processing systems including an Arduino Uno, a Raspberry Pi, and a SIMATIC IOT2020 using not wall power or even a battery, but via chemical energy converted by himself through a hand crank, along with a model airplane engine. The setup uses geared DC motors acting as generators, while the eye-opening results are displayed on a 16×2 LCD screen.
Check out the video below and the project’s write-up to see how its done. And by all means, make sure you do your experiments in a well-ventilated area if you’re going to use a combustion engine!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
