Jeanna:

Thank you for those tests.  This is very good information to know.  This fits in with my wonderings about the TIP 3055 vs the reg. 3055 or the 2N3904.  If we don't NEED it, don't use it.  Thanks.

I started another light project tonight.  This one is a variation on the Jeanna Light except I am using a Tupperware container and the light source is an 18" floro tube.  The tube stands straight up form the container and I am only using a single 3 3/8" OD toroid this time.  It looks kind of cool and if it lights, and lights brightly, it will be even cooler.

More to come when I get it done.  I may name this one the Pirate/Lidmotor/Jeanna light. (Shiver me timbers)

Jim, Electricme, gave me an idea about winding the primary with 3 strands of 22 ga. wire twisted together and soldered on the ends.  (and wound like it was one wire) It may help, it may not...we will see.

MrMag:

I remember well you kind offer to loan me a scope.  That is what motivated me to look on Ebay which is where I found the one I have now. (Tectronics)  I will not forget your kind offer, and it is this type of cooperation amongst us that will help us move forward.

Thank you once again.

Bill

I hope you find the one you have useful. From what I see there is a lot of cooperation going on in this thread. I wish I could give more input but I haven't been able to get close to my bench. Hopefully, I'll be able to start soon.

I am so glad to hear this instruction.
Thank you. I am going to try it right now.

But what do you mean by  I think you mean I can now put this into the C-E spot with the diode and something might happen?
Thank you for  this information as I had not been able to make your circuit work.

Hi Jeanna . I thought about what one of the members asked is the light on My secondary was lit when i charged the cap from the rectified ce junction . I said yes it was lit but i forgot that all my caps are setting at 0.500 volts . so when i put it on the ce junction ,yes the secondary leds light but if its lower than that no they dont light until it reaches .5 to .521  . They get brighter and brighter as the bcap reaches its peak . for me its between 2 volts and 2,6 . Also i notice that the JUMBO super bright leds actually light better than the cheap china 20000mcd 21 ma leds . better to go with a higher rated led like a strawhat or jumbo 10mm 100,000 mcd . they light quicker .

Got any snow out there?  We have plenty for this area.  They are not used to it at all.  More on the way from what I have read.  This global warming is killing us all.  9 degrees F here tonight with a high of 19 on Friday.
