Original poster: Vardan <vardan01@xxxxxxxxxxxxxxxxxxxxxxx> Hi Dan,Just put a loop of wire and an LED on a long stick and start probing around the primary with it. After a short while, you will get a good feel for where the fields are and how well they energize the LED. Possibly a useful toy for mapping out the primary fields and how they react to transformers and such (conventional coils).
You have already thought of just using a current transformer as a power transformer to run just about anything you want *;-))
Looking forward to your book this Friday. It is autographed? The antique show says that signed copies are far more valuable 100 years from now :-))
Cheers,
Terry

I just did some initial calculations, and i think i should be able to adequately illuminate a single LED from a 1-2 turn coil on a PCB board.Calculations: Primary Coil (12uH) LED Coil (0.3uH) 1-2 turns, 2 inch diameter on copper boardCoupling (calculated with MANDK) k = 0.02 (LED Coil about 2.5 inches below bottom turn of primary) Avg Current for 300us pulse, 100Hz PRF is about 20mA. A bit high, but for a ballpark, not too bad.Time to prototype!!! Dan "DRSSTC : Building the Modern Day Tesla Coil" Book - Coming on May 12, 2006!!!! http://www.easternvoltageresearch.com
