| Description | Our vending machine MuMaExpress |
| Owner | Munich Maker Lab |
We have a vending machine (aka. MumaExpress) at the space (the same one as for the Archive: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
Programming
Programming is super easy. There is a really nice manual and a small keyboard. Changing prices or other small adjustments only take a few minutes.
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.

Maintenance
14.02.2025: Power supply broken. Details: https://munichmakerlab.slack.com/archives/C78KSC5EG/p1739484743521549
30.05.2026: Scheibenheizung wurde abgesteckt via Stecker C8 und Pin 2 (rot/blaues Kabel). Deaktivieren via Menü war nicht möglich. Scheibenheizung macht nur im Kühlbetrieb Sinn. Heizung hat im Leerlauf immer 60W mehr verursacht. So hat der Automat mit LEDs nur 20W im Standby.
