Joule Thief

I tried the neon JT with a different toroid and it required changing the base resistor to 500 ohms to light the neon.

The Transistor must be able to handle about 90 Volts Collector to Emitter Voltage,
so if you use a lower voltage type transistor it might smoke !
Otherwise well done !

I found some more about mag amp. Remember they can be used for a lots of things even switching stuff also as a regulator, not unlike the jt.

Well there it is. Nathan Stubblefield's make and break right in his design. It is what I have always thought he meant. And this sez it.

I just bought 280 leds for $75  Darn. I have to mess with the christmas wires now! but I guess 27 cents each with diffuser included really is an OK price. I sure hope they are good ones.

@ Jeanna:

Just got back from work a bit ago.  Heck, I bought all of my 400 led Christmas lights for less than $18.00.  If I had waited until after Christmas, I could have obtained all strings of 100 for about $3.00 ea 100.

Now I have to go back and read all of the many posts I missed.
