Solid State Bedini Oscillator
« on: August 20, 2008, 06:38:20 PM »
I've just put together my second one of these using 1200 turns #25 (bifilar) plus 50 turns in the middle of the coil of #23 as the trigger coil. I have yet to assemble the final discharge section, but while testing some interesting anomolies came to light; While tuning the 2n3055 base voltage to the sweet spot (charging cap holding at to 320v) i noticed the workshop radio getting interference - note there are NO moving parts or arcing devices - I turned off the flourescent lights to make sure they weren't playing a part. Next thing I found was that my bench scope was registering negative spikes without being connected to anything... Here's the good bit; using myself as an antenna, and holding on to just the probe (no earth connection), the scope showed strong neg spikes in tune with the oscillator... Why would I be seen to the scope as having energy subtracted from me?, I know the obvious answer to spring to - but is there a more plausible explaination?.

Positive or Negative spikes on a Scope doesn't mean the power is being added or subtracted.
It just indicates the direction of current flow.
How many volts where you getting while you held the probe?
How many volts are you putting into the trigger coil?

Interesting experiment, keep us posted on your results.

Hi,

Once your charging cap is up to 320V it means the flyback pulses at the transistor collector are also of high amplitude: have you checked the pulses between your transistor collector and emitter?  (ground of probe goes to emitter and the probe tip goes to the collector)   You have to see 'those big' negative flyback pulses...

When you are very near to the working circuit your body can serve also as a collector (an antenna as you put it) and 'magnify'  the pulse towards the media around you, especially when you tinker on some components with your hand, the near field of the high voltage pulse can be 'amplified' by the human body, without being aware of it i.e. without getting a shock. 
If you put a load across the charging cap, then the load will reflect back to the flyback as well, hence this phenomena should get reduced.
If you go through Dr Stiffler's thread here on this forum, you can also read some interesting similar phenomena.

Thanks for the feedback, i'll look a little closer and come back with some numbers.

Your body is also a good conductor because of the water/salt composition. I am beginning to think that your circuit has been tuned to a certain freq and its picking up or sending signals.

Or it might be a radiant energy transmitter.  :D
