| Apr 23, 2017 at 23:31 | comment | added | Not Entirely Evil | Updated the post with more info. DerStrom8: It wouldn't let me add my actual drawn schematic, so I was working with the cruddy tool in here. Also, the purpose of the switch was to require an extra step to turn the thing on. (Step 1: flip the HV switch, step 2: get clear, step 3: flip the dimmer switch on the transformer.) @wbeaty: Thanks! That's great info and I'll check out that project as soon as I get a chance. Neil_UK: across the spark gap with nothing else connected at all. Attaching the MMC kills it so it won't even jump a paper's width. | |

| Apr 22, 2017 at 3:44 | comment | added | wbeaty | Some light-dimmers may filter the sharp AC transitions, and so not work. Here's an old project from Radio Electronics, provide your own triac circuit to drive an ignition coil: learningelectronics.net/VA3AVR/circ/hv/l-bulb/l-bulb.html Note that they use 2uF for their AC ballast capacitor, not 0.44uF. WARNING: when it starts working, it may destroy any multimeter connected to the HV side. DMM isn't rated for measuring many-KVs signals! | |
| Apr 22, 2017 at 0:32 | comment | added | DerStrom8 | What the heck are you using a toggle switch on the high voltage side for? That's just a stupid idea altogether. This schematic is a mess and does not convey any useful information. Please redraw it. There should not be a ground on the input to the dimmer switch. The primary coil should also not be grounded. | |
