I wanted to share a project I’ve been working on for some months by now. It’s about building a lightsaber replica toy, with sound and light effects, like the original ones already being sold, thought this one is built with the electronics effects powered by an Arduino Core, and it’s mostly done with common materials, except for a few things that are bought from a specialized store.
The electronics consists in a custom PCB with a common Arduino configuration (mega328, 16Mhz, bootloader, etc…) and coupled with a slightly modified Ladyadas’ Waveshield circuit.
So far I think it’s going pretty neat. The sound effects are ok, but I’m working on enhance them. It still does not produce the extend/retract blade effect, because it does not use a string of LED, it only has one Luxeon LED at the base of a empty blade; I did it that way because it’s the preferred method in the custom lightsaber construction scene, but I’m very disappointed with the result, so I’ll be changing it to drive led strings with the whole set of effects.
