Thanks everyone for your help on the neon.  For some odd reason I had the idea that the neon took a lot of juice to light and that was why I couldn't understand why the neon would light up and not the cfl.  Anyway, I went back to the old boards and put them back together with good parts and they are working once again, along with the others.  From now on, I will be checking the alligator clips to make sure they work properly before I blame the boards for any malfunction.

I hope you saved the transistors and transformers from those boards.
You were talking about making a smaller circuit.
If you wired the primary up to the transistor  you would have most of a VERY small JT
I would try it out  using a pot .......but once you find the right resistance I would replace the pot with a resistor to make the circuit smaller.

I guess I should  ask....... have you made a JT with a transformer before?

I am working on that very thing at the moment using the idea of the fellow that I posted about a few pages back using no board and just wire for the traces.  It will be very small indeed.

PS  I agree with MrMags...congratulations to everyone here for making over 1,000 pages of postings and yet we are still going and coming up with new and interesting ideas and circuits.  Very well done.

I am planning on making a small JT with the parts from a camera board .........as soon as I can find  my boards.

Once it is  done  I am planning on trying to modify the circuit  to work like a ringer.

Gary:

That will be very interesting.  I look forward to seeing your results.  That is an excellent idea.

Maybe I made a mistake on posting my 1.5v to 12v circuit on page 998.

But I thought that because it was just to build a switching circuit to give  a signal to a transistor with the 11.46v output from the coil to just hit the 1.5v battery and stop inmediately the transistor was an easy task to some members that play with electronics everyday.
I was wrong, nobody paid attention.

HHHhhmmmmm

1.5 to 12 V ......that has been on my to do list for a while.

So many circuits.............so little time
