This is a encasement for the BI1 (body interaction 1), a simple electronic device which can detect motion. A vibration motor is included, The BI1 can be progarmmed e.g. to react with vibration pattern to motion. With the power of the vibration motor the mouse comes alive. The body interaction device is small and easy to embed in a 3d printed object. The BI1 is build on the Arduino platform, communicates wireless with other BI1 and comes with a LiPo battery. History: This is new version of the BI1 encasement. The cap is fastened with two tiny M3 screws. It is a remix of the red BI1 and the cute 3D Mouse.
