For quite a while I’ve had this project idea in the back of my head that would involve using many Nixie tubes.
These funny looking cold cathode displays were actually introduced during the 1950s and unfortunately need quite a high voltage to work (from 100V to 180V depending on the type). This meant that I had to find an easy, cheap and (if possible) not dangerous solution to power them.
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.
