Soldering 17 circuits, even with only a few components each, was going to take me more hours than I could contribute, so I built the circuits on breadboards. I had some small breadboards in my stock already, but not enough. Fry's carries bigger boards, which I bought and cut in half to make enough boards. The circuits all ran on four AA batteries. In the game we used Kirkland brand batteries, which lasted for between 60 and 100 hours, depending on how many LEDs were being driven. We only needed about 12 hours of service, so this was more than enough storage for us.
