Electric Ring Wheel Prop - Is a Tesla Coil the way to go?
I need to make an electrical ring prop, and while I have basic electrical knowledge, I'm a noob at High Voltage applications. What I need is to produce electrical streamers, such as what you see from a Tesla coil (at least an inch if possible) to appear to be sparking off and around a spinning wheel held in a fork (ie. the front wheel of a bike). What would be the safest and cheapest (in that order) way to accomplish this?
Optional requirements: It would be perfect in all ways if it uses a DC power supply for locational freedom, and if it can be made so that a person can actually sit on the bike without you know, dying. But work-arounds for those are doable, we just need the visual effect.
CG isn't in the cards for us, and we've tried the others already. LEDs and glowsticks etc. look just like what they are: cheap spinning lights, and pyrotechnic type sparks and such look more like the bike is busted and about to blow than anything else. Your first thought is "oh my god you're frying the bearings!"
