I'm trying to create a prop similar to a Next Generation era tricorder with LED lights inside a handheld device, but I have no idea where to begin. I know that some circuit boards have LED's and you can use light pipes to send light out, but I have no idea how to make that work? Can you buy boards with LED's on them already? Do I have to make my own light pipes? What about powering the device? Do I have to program the lights if I want different lights to blink and flash differently?
