Final Project

The Idea

A "Baba is You" inspired lamp, controlled by a sliding puzzle (like the 15 game). Can slide tiles on a board to form rules like "LIGHT IS BLUE" (e.g. to change color of lamp) or "SOUND IS ON" (e.g. to play music).

Components

• Baba shaped lamp shade (3D printed)
• RGB LEDs - Neopixels
• A 3x3 board for placing tiles (3D printed)
• Tiles with magnets inside (3D printed)
• PCB with grid of hall effect sensors (4 for each grid; each one acts like bit to encode tile based on polarity)

Schedule

• By Nov 28: design lamp shade, 3x3 board, tiles
• By Dec 2: print lamp shade, 3x3 board, tiles
• By Dec 5: design and mill PCB
• By Dec 10: programming
• By Dec 12: integration, testing

Baba Lamp Shade

I found these STL files online. Seems like it might be a bit small though, maybe there's a way to scale up?

Encoding Each Tile

Each hall effect sensor acts as a bit. n hall effect sensors per tile position gives 2^n possible distinct tiles (high or low for each).

Multiplexing?
