I remembered that Nixie I had lying around, and, that many years later, I thought I might give it a go to make a pendant. I also had this friend in a low moment, and I dediced to improvise a Dieselpunk photoshoot to cheer her up a bit. (and also have a nice model for the pendant, if I managed to get it to work.
Since it was improvised, I didn’t had much time to get the nixie working. I happened to have a used electroluminiscent driver from work, rated at 5/100V, and supercharged it with 12V, thus having around 200V at the output. Yeah, you guessed it, efficiency went down the drain in there, but it worked.
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.
