Replication of Jonny Davros One transistor with trigger coil oscillator

Nice job man.

I believe if you can up the voltage just a little bit, you can light the other half of that CFL. This happened to me in an earlier joule thief experiment. Once I got the voltage high enough, the entire CFL lit right up. (I thought at first I had a bad bulb or something.)

Keep it up.

I worked on this yesterday in an identical way---using an ignition coil. Got mine to work on 5v by using a Darlington pair (two MPSA06) arrangement. I also got some nasty shocks. Ouch!

Thanks for trying this Dave.Great idea too use an ignition coil.i was wondering if they would work with this circuit and you have shown they will.Nice job.Regards jonny.

Thanks Jonny. In my tests I got a 'feel' of the output by accident :-). I can attest that the output is of a lower frequency then an SEC and can be quite painful. This may be due to the large ignition coil I used in place of the samller trigger coil. Perhaps the smaller trigger type coils are the way to go for better SEC type effects. Either way, the circuit is interesting and rather efficient. Thanks again for sharing your ideas with all of us.
