Made by @martin and @jakob
Goal:
A Donation Box that plays silly souds when donations are made.
What we used:
- Raspberry Pi 2B (for media playback)
- Arduino Nano (for sensor reading processing)
- VL6180 ToF Sensor (to detect donations)
- Some sort of amplifier and speaker @martin can tell you more about xD
We used @martins Prusa Mini to print a crude box that holds the donations and a fitting lid with cutouts and room for the ToF sensor. Afterward, an acrylic plate has been cut using @jakobs diy cnc. Below you can see it put together:
The VL6180 can detect which hole is used and send a specific command to the Raspberry Pi to play different sounds.
The printable files are uploaded on printables: https://www.printables.com/model/498817-donaionbox
The code is published in our wiki: https://wiki.technologiehub.at/en/projects/donation-box
Conclusion:
The box was successfully tested at Makerfaire 2023
The quick realisation of this project shows the potential of Technologiehub, when a couple motivated people from different fields work together against a common goal and make a cool, working project within a couple of hours.
