Final version (v2)
Hardware and firmware by The IceBear,
support board and box built by The AirBear
This second version was built to stay in service. It was finalized in Febuary 2012.
After problems with the power supply (we used the on-board supply and everytime the speaker sounded the system rebooted) we built our own power supply board with some other integrated circuits (for the speaker and the buttons for example).
Finally we created a nice box where all cables, boards, buttons, screen and speaker fitted in.
