Inspired by Loek Vellkoop, I recently chopped up a scrap kid’s bike to see all the materials I could reuse from it. One of the elements that really struck me was the wheel rim after I had taken all the spokes out.
Solid, made from steel, and perforated with precisely spaced holes, I thought it would be cool to light it up with LEDs as an accent lamp, or just something cool to trip out on. So, that’s what I did, and I’m proud to say that I whipped it together in an afternoon while my family was out shopping.
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.
