New News: The new prototype boards are working great and only need final text revisions.
Old News: Before the the badge needed low voltage 555 timers to work properly. I’m also dropped one of the LED’s and we just having two on the board. After looking over the prototype board I made a lot of changes to the board in Eagle.
A interactive circuit for the board is below. You will need to click the switch next to the battery once you start the simulation.
