Hey guys, Whats are the practical uses of a tesla coil? I see SO many tesla coilers around the globe. And I am wondering..the tesla being a HV output with lot...
... I already pointed him to the lasers list. It could use some fresh blood, the traffic on it has been very low the last few years. If anyone else wants to...
... Virtually none whatsoever. Some writers have talked about Tesla coils being present in TV sets, but the flyback coil in a TV set is not at all a true Tesla...
Hi I am thinking of building my second sectorless Wimshurst machine, I am planning on using 20" discs, is a thin disc better than a thick one? I have a choice...
Hi Bob, Depends on the material that you are using for your discs. Thin discs are desirable but you need the material to be rigid enough as not to deform. The...
Hi Chris I wasnt sure if the 2 discs were attracted to each other, the material is polystyrene, it looks like perspex (maybe it is under another name) comes in...
hi all, I currently have a High Voltage Supply (about 50kV), as for amperage I am not very sure. Can somebody suggest a way for me to measure the current? I do...
alright mate. build a lifter! u know those hovering craft. or you build build a vdg and give it a high power source for a REALLY big spark!! good luck ... I am...
