@Kooler,
I love your drawing. It is sooo good. soo 3D

@jim
Same brand bought at the same time recharged all together in the samre charger.
It is very interesting, Isn't it?

@everybody,

I am pretty excited about the video I will be making.
I took a preview still to show you why.
I modified a 19led LOA bulb last week and yesterday I got the final piece and it just went all together. You will see the video 'how to' , but here is the still pic. in front of the 4w little tube running off the circuit I made up today.

Nice work there , it seems to give more light then cfl.

You raised the bar again !

Good work!

Excellent!!  That looks so cool, very bright and, you can carry it around, ha ha.  We may have to call this the Jeanna Light II?  That globe looks like it gives really good diffusion of the light without choking it off.

Very cool.

Xee2:

Thank you for that explanation.  So I have more volts at a lower freq.  I made some other changes besides reducing the winds on the collector so maybe that is why the freq. lowered?  When I get it all sorted out, I will post the changes and results.  it all started because I fried that 15 turn variable resistor and switched to the only other kind I had which is a 1k.  The base is only calling for 45 ohms at this time so that is a little unstable using the 1k pot.  I will get some other resistors once I get it tuned.  Thanks for the safety cautions as well.  One can't be too careful and I do appreciate it.

i was playing with my new schematic software..lol(ms paint) it's more fun to make them this way
cause it to cold to go work in the foxhole.. (15'' snow)
this is very dangerous... BUILD AT YOUR OWN RISK

Kooler very nice circuit. Can you please give the parts of that?
Thanks
