We gutted the old Volkshuis cash-register.

The money-tray is in use at the bar, but the top half with buttons and screens needs a brain!

One of the donated BeagleBones (called: Not-A-Phone) is serving this purpose, hence the name.


  • gut old electronics
  • attach keyboard/buttons to BBB with custom header
