I built this little gadget over the weekend, and I think it turned out pretty good.
A complete thunder and lightning effect in a box!

Ummm... "large" and "small" are really bad descriptions for the relays. You should list them according to trigger voltage and switching voltage. I can find relays that switch 120v AC on and off using 12v DC trigger current that range from the size of your pinky (small) to the size of a 1 quart volume coffee can (large).

Blarghity, sorry if the description was less than stellar... I guess I made the assumption that if it all ran off 12 volts, the relays would use 12 volts as well.
And most relays don't draw a heck of a lot of current. In this case it doesn't "relay" matter. LOL as long as the "small" one can switch a small digital signal, and the "large" one can switch 120 volts, that's what counts. They were just ones I had kicking around, so I repurposed them.
