Re: [TCML] [UPDATE] Tesla Coil Computer Interference
Alright, basically this was my problem; After installing Gary's Primary Coil (Simulator, Emulator, Substitute, Place Holder, etc.), whenever I ran the coil, my computer would start to scream a solid beep tone from the motherboard mounted speaker. Turns out that it would stop after about 30 seconds and would act as if nothing ever happened after that.
The coil was in no way grounded to green wire ground, nor did I use (or need) an RF ground.
The coil runs on 120V/60 hertz (US).
0-140V Variac (Problems arose around 120V anyway)
NST is 15kV 30mA.
Terry Filter always attached.
I bought some ferrite beads off of eBay for cheap, but they were of excellent quality (I'll post specs on those later). I placed 2 on the coils power cord, one at each end, about 1-2 inches from the ends. Same with computer's power cable. The rest (8 total) went to expensive appliances around the room.
Now it works fine. No more freaking out the computer!
