Peanut M&M Dispenser Maze

The video provides an overview of my M&M dispenser project, which was made to compete with other candy dispensers around our office (M&M, mint, and jellybeans). My goal was to make a dispenser that was somewhat more entertaining than reaching into a jar, but also reduces the large M&M flux caused by greedy handfuls.

The dispenser maze requires the prospect candy-eater to tilt the maze table and guide the M&M through the sequence to the Win Bucket. There are a number of open wall segments on the maze, beyond which lie the fail ramps that roll the M&M down to the fail bucket. While the M&Ms are still accessible in the fail bucket, candy-eaters must face public scorn and shunning from colleagues if they eat from there.

The maze is made up mostly of thin plywood glued together. The actual M&M dispenser is commercially available, with the only necessary modification being the servo-actuated arm.

Control of the maze is provided by a hand-held controller, which uses 8-bit Nintendo POWER/RESET buttons for M&M dropping, and an analog Playstation joystick for table tilting. An ATTiny 861 microcontroller reads the analog position of the joystick and generates PWM commands to drive the pitch and roll tilt servos, which are connected to the table and provide roughly +/- 10 deg tilt angle.

The maze is similar to the board game "Labyrinth".

The video ends with a brief discussion of ongoing efforts, which could include:
- Additional/Swappable Levels
- Dynamic Maze Elements
- Turbulent Disturbances
- Autonomous Maze Navigation

- 8-bit NES buttons and Box: All Electronics
- $3 Servos: Hobby King
- Dispenser: eBay (used)
