small, adjustable time delay 12v relay.

Good morn', and a bump. I wanted to drop in and let everyone know that while I appreciated your input, I found a solution in a circuit made by reuk. I ended up specially ordering four circuits, each with adjustable on and off times down to tenths-of-a-second. I also ended up going with a 14.4 setup with a nice, dandy Makita Li-on battery pack. Mmmm. So, thanks for your input - that's the end gameplan.

Unfortunately, that wouldn't have worked for the purpose - the on time is far, far too large. After I ran my tests with the heating elements and the hypercolor material, I needed on times as low as half-a-second and off times just about two seconds.

They'll be random enough. Each one of them will be set independently of the others, so they'll at least seemingly 'pulsate', which is well enough. Each one was about 17 euros... or pounds. Whatever it was. It'll be worth it in the end. Best superhero costume I've ever done. :)

what an awesome project! post pics when you are finished.
