Regeneration and the Toroidal Power Unit

Darren,

It's 50 mA, not 5 mA.

How did you measure the current being supplied?

5mA supply seems very low.

I measured the voltage with a voltage meter WHEN OPERATING.

I measued the amps with the same meter BEFORE it gets to the smoothing capacitor, so inbetween the transformer (which has its own smooting cap inside) and my smoothing cap. Ã,  With a scope, the voltage is a SOLID LINE, no fluctuations, so it's very accurate !!!

Why do you want to know the base voltage waveform? Ã, I was showing that in one of my videos. Ã, Have a look, it's somewhat sinusoidal, but its a composite of the different picewise segments representing the stages of operation: rampup, discharge, etc..

Ok Guys,

Here's my blocking oscillator.   A one transistor elegant circuit !!!

So, instead of the battery I placed a 40 watt lightbulb !!!

Thanks for the diagram EM.

Can you say, what thickness of wire and what is the PNP transistor?


Thanks,

Dave.

I can not say because I don't know.Ã,  Marco asked the same thing.Ã,  

The writing on it is dim or erased or I'm blind.Ã,   However, you don't need a PNP.Ã, 

The diagram marco posted (the yellow color one)Ã,  is the original that inspired me, and they use an NPN.Ã, 

Someone on this forum had posted that link when I originally discovered for myself the oscillator.Ã,  Thanks to whoever that was.

Hi EM,

I guess the transistor is not so important, however if it does turn out to be important, perhaps you have access to a component analyser at work?

Whats your next stage?
