This is a project for Burning Man 2013, which doesn't yet have a good name.

Project Status

2012-09-17: Completed schematic and board layout for the Hub LED board. Will submit it with the main Hub board.
2012-09-16: Started designing the Hub LED board that plugs into the Hub board and provides R, G, and B high-power LEDs and FETs to control them.
2012-09-12: Finished checklist on strip board, CAMed and submitted via OSH Park for manufacturing.
2012-09-11: Started working through checklist, needed a bunch of changes to make IR emitter/detector line up.
2012-09-09: Started board layout.
2012-09-08: Put together BOM and designed schematic for the strip board containing 5 LEDs, the drivers for them (WS2801), the IR emitter/receiver, and the ADC/logic for the IR.
Wednesdayish on the playa: Started throwing around ideas for 2013's project.

Random Thoughts

Tic Tac Toe game in lights on the playa
Jumping on a square makes a move
X/O indicated with colours instead of symbols, as it would be harder to design LED symbols that could be jumped on
IR sensors used to detect people's location?
Strips of LEDs/IR sensors run in clear tubes like the Man perimiter's LEDs
Hubs located at cross points which have high powered LEDs
All run off the StrichLux system the same as Beacon4

As sensing jumping vs. standing is going to be hard, Gary at the lab suggested an "invisible maze" which I'm now trying to work out details for that would work.
Higher-resolution grid than was planned for TTT, maybe 5x5 1m or 2m squares?
Stepping into a square causes the system to generate a maze with the square you stepped in as the starting square.
Maze is briefly flashed on the lighting strips, then goes dark again.
"Bumping into a wall" on the maze causes a buzzer-type-sound and that wall to go red.
- Would it also flash the entire maze again? Probably need to wait and see what works best once the system is built.
Each bump is added up on some kind of scoreboard
- Could have a high-score-board too, with some way for people to enter initials?
Would probably need voice prompts to tell people what to do?
