I tried to rebiuld a Don Smith Device

Spark gaps are broadband transmitters. The spew.

You're correct.  I think they were outlawed by the FCC for that reason.  Lakhovsky radiating coils should be able do the same thing over an enormous bandwidth range.

I did see a schematic once awhile back that indicated that choke coils at the input were EMI suppressors.  Then I found this:

They're designed, I imagine, for 50-60 Hz.  The question is:  Will these have any beneficial effect on a spark gap or Lakhovsky coil?

Thinking of spark gaps and the magnetic field watch the first few minutes of this vid

It is now 08/22/11. I have been at it sourcing parts for a second Don Smith type device. This is my own design. It is much simpler to do. The initial frequency can be anything necessary to generate maximum power with parts on hand. Then d/c it and use a standard  frequency circuit for 60 HZ. Most AC lines are 57-63 cycles all the time anyway. Not dead on 60 HZ.  The caps can be 600 volt units. This duplicates Tesla's spike generators he used. I'm having to build the Neon Sign transformer because all of a sudden you can only buy 4KV 60 HZ units. The 35,700HZ 30,000KV are no longer made by "Government" orders. Something about a danger to the public.

Never Give Up!!!

Dr Bob,

Could you please post a schematic & parts list for your Don Smith unit?

According to all of the posts I have read through the years, nobody seems to be able to make a Don Smith work.
There are HUNDREDS of frustrated folks out there that have really tried to do it, but to no avail.

Thanks.

I read a long time ago in a (probably now-defunct) free energy magazine that the article author indicated only the genius inventors of decades past (e.g. Moray, Tesla) were born with the innate ability to tune their creations by mere "feel".  Daniel Pomerleau is a prime example.

Even I have a hard time getting some results from simple experiments.  The Joule Thief for OU (as such) is still elusive, is it not?  Has anyone claimed the OU.com prize yet?
