I looking to build a target module that could be attached to different devices. It could be attached to a building and movable flag for capture the flag or support trucks. Anyway you get the ideal. I have seen them here but never are the details given on how to build them. I can solder and know the difference between a resistor, cap and transistor. So really I just need a list of parts and their source and maybe a basic wiring diagram of some sort.

Thanks
