The other day at the hackerspace Dave was talking with members how to improve the safety in the space. Especially how to prevent other people from leaving dangerous devices running unattended. They quickly came up with a button that needs to be pressed once in a while, or otherwise the machines power would be shut off. Since it's a hackerspace the expectation of people building crude "arduino with servo" devices to circumvent such a device was high. But having a 4x4 button matrix that would indicated a random button to press sounded tougher to get around, so the idea for this project was born. It also looks suspiciously like a midi-controller.
