The inspiration came from this project, which is also going to be its main purpose. I also have an odd fascination with vacuum tubes, and this looks like a big one.
The case has an LED inside that’s hooked up to the GPIO pins. However, as of this writing I haven’t assigned the LED to do anything but just chill out inside the tube. The inspiration link above features a script that’ll get it to blink when files are synced. Since all we’re
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.
