Vending Machine

We have a vending machine at the space (the same one as for the Self-aware Vending Machine project)

Technical Details

• Rotating tower, with 12 levels, and 16 slots on each level
• Mei CF 7000 cash acceptor (Manual)
• 3 keys, Severin has one

Issues

• One of the slots doesn't work on all levels. It's marked with an X on the tower.
• The cash acceptor has some issues with tubes not working. We have a coin cassette for 5, 10, 20 and 50 cent coins, but the 50 cent coin tube is broken. Our workaround was to create a custom cassette which only has a 10cent and a 20 cent tube. All other tubes are disabled.
