Prototyping: Donation Box Tilt Mechanism, Part 1

Donation Box - Rotating Lid / Prototype from iamnotarobot on Vimeo.

Here are some prototypes I built to test the donation box mechanism that will sit next to the multitouch table. I'm trying to find the correct servo settings to tilt the floor and open/close the lid. 

The servo code is a little jittery at the moment but this prototype is helping me work out some final design and engineering issues. I wired a rotary knob and a reset button so I can control the movements during testing. The final version will be controlled by the users score on the multitouch table and a signal will be sent to the donation box to tilt the floor according to the outcome of the game. The final components will be laser cut so everything should move as smooth as silk when finished.

The donation box will be divided down the middle – if you win, the floor of the donation box will tilt to drop your money into the “matched donations” side of the canister and if you lose, the floor will drop your money into the “unmatched donations” side.
