(OK, calling it a “hack” is an exaggeration, but I couldn’t miss the opportunity for the double entendre.) After building my Drawdio, I realized that I didn’t have a thumbtack to attach it to the end of the pencil (not Adafruit’s fault, I had just purchased the circuit board). So, I decided to take it in a different direction… It’s very simple to build, once you’ve made the circuit: find a knife with a non-metallic grip (wood, plastic, or rubber should all work). Attach the Drawdio to the handle — I used a zip-tie. Using copper tape connect one end of the circuit board to the blade, and the other end to the handle so that your hand will be touching copper when you hold the knife. That’s it! To use it, hold the Syntheslicer in one hand and a fork with a metallic handle in the other, and start playing with your food! Please don’t use your Syntheslicer as a weapon. Also, I wouldn’t recommend waving it around in public, especially in Boston: they’d probably think it was some sort of stab-bomb.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
