We love doing electronics projects. We love teaching kids and adults how to build awesome electronics projects. For years now we’ve found that there are really only two ways doing DIY electronics: Buy a very expensive kit; Use inexpensive off the shelf parts that are hard to use. There didn’t appear to be any middle ground between “easy to use” and “expensive.” So we created our own open source system: CRAZY CIRCUITS! At the heart of this project is the Crazy Circuits Touch Board. The Touch Board is built around a Teensy LC microcontroller and features capacative touch inputs. Any conductive material, from a cup of water to a potato can be turned into a touch sensor, no grounding necessary. Here we turn the word NASA into a touch sensitive switch with conductive thread. It triggers the LED stars twinkle randomly. Ooo, shiny.”
