| Using a coffee-cup as till for our little sweets/drinks shop has proven to be problematic, because some people took it as free-to-take money source. We will replace it with a piggy-bank type box where money can be thrown in but not taken out.
A beautiful old home-made PSU functions as box itself. We will add an arduino driven code lock that can unlock the box. | |

The PSU has a large number of contacts in the front which we will use for entering the code. A cable will connect one of these contacts to ground at the time, and the right sequence acts as unlock-code.
