Here is one that I’ve been working on, it contains an 8mhz Trinket, 2x neopixel jewels and a bit of silicon wire.
The neck is hard drive platters, the sides are drive heads, and the top the motors. A little tubing helps even out the Giger-esq look. The skull is a candy dish from Amazon, and the “plate” is just a cut-up aluminum sign (cheap way to get thin aluminum sheets).
I’m still thinking of what to do with the base (from an old barcode scanner), but I might just cover it with fabric. I’m also working on what I want the eyes to “do”, but I omitted any sort of sensors as another box will most likely contain an AudioFX board and PIR sensor. My buddy said I should use a sonic sensor and have the eyes glow brighter as a subject approaches…maybe I need to build another.
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.
