This is a shell for your circuit playground. There are cutouts for all the switches and sensors as well as the USB and JST headers. The back has been left open so that you can still use the pads on the back to trigger capacitive functions.
There is a hole for the ground connector if you want to put a keychain through it and carry it around.
I created this after telling my wife that I'd like to play with it on a plane, and her telling me people would think it's a bomb.....we don't want that now!
V8 has a the larger USB plus a larger hole for the Speaker component as I found it was causing the speaker to break off.... :(
There is also a Simpler version with a large cut out in the middle for all sensors and inputs...still effectively diffuses the light but leaves the middle open for more access.
