CharmBits are module circuit wearables that educate children about circuit design and basic electronics.
This was a semester long project in the graduate-level Interactive Device Design course at UC Berkeley.

User Research & Target Market
There are many competitive products in the educational marketplace, such as littleBits, Goldieblocks, and Snap Circuits. CharmBits addresses a missing void, however, by teaching children about circuit composition while still providing for personal expression through wearable jewelry.
iPad Companion Application
The iPad app walks parents and children through interactive stories that teach electronic concepts and help debug problems along the way.
We scoped this project to be wearable, which dictated that our modules be quite small. Fitting all the hardware into these small modules proved quite challenging. We also would have liked to mold our parts, as 3D printing our parts led to more brittle and less attractive pieces. We would have also liked to create a flexible PCB to mount into our band, as the wires created a bulky and rigid band.
