Yeah, it turns out that I was testing it incorrectly. Whenever I wanted to send the voltage through the coil, I would touch both ends of the coil's magnet wire directly to the capacitor, creating a large spark. I later realised that the best way to test it was using an actual switch to close the circuit.
Hi! I'm currently trying to replicate this really awesome instructable, however, I seem to have a problem regarding the coil. When I connect it to the capacitor bank, all I get is a loud spark from the point of contact. My capacitors all seem to work fine and are able to produce a total ~300v. When connected directly to two AA batteries, my coil works fine and a magnetic field (although weak) is formed. I have a feeling my coil isn't long enough (it's about 5cm long with 4 layers total, 22 AWG), but I'm not completely sure. What do you think?

Great instructable! I made it with the Bluetooth module and it works perfectly! I have a few questions, however. How do you make it go backwards using the smartphone controller? Also, is it possible make the volume rockers control speed rather than the screen slider? I hate it whenever my screen freezes while I'm riding. Thanks!
Hi! I'm experiencing the same error. Were you able to resolve it?
