PROTOTYPE 4 - September 23, 2016: With some webbing and rivets from https://t.co/Zw35WK13mM , I made a crossing-guard style strap, and moved the LED ring to the chest portion of the strap.
But the nRF401 was still flakey when sending messages back and forth.
JULY 2016:
2016 was a sad summer for me. The device worked.
But only just.
Printing it took the better part of a week.
Assembling it took another week.
I let the soldering burns on my hands heal and went back to the drawing board.
PROTOTYPE 3 - July 26, 2016: Communicating by nRF24L01. Tags by RFID, lights activated by events in the game. Video shows registering with the system, then setting someone (on the left) into the "PowerUp" state. It's an unholy monstrosity. But it...just...might....work!!
PROTOTYPE 2 - March 3, 2016: After almost a year of experimentation and trial-and-error, I put together this proof-of-concept built out of salvaged parts and two Radio Shack "project containers". This was a test to verify that I could register a tag and transmit news of the tag.

PROTOTYPE 1 - APRIL 30, 2015: Since the original game relied on colored circles (red, green and blue) I first thought it might work to use a color-detector to register a tag.
