I DID ON MY JOULE SCREEMER , RUNNING A FACTORY !

oK HERE IS MY 6 INCH FREE RADIO FERRITE ROD REWOUND FOR THE LAST TIME . TWO LAYERS OF #20 TAPED  AND ONE COPPER WINDING AS THE PRIMARY . THIS ONE BLEW 4 TRANSISTORS BEFORE I USED A NEON ON A TIP3055  AS ITS THE ONLY KIND I HAVE LEFT . i HAVE BLOWN 8 2N3055'S AND ONE NICE DARLINGTON . iT WONT TAKE OVER 5 VOLTS MAX . THIS IS A HIGH POWERED JOULE THIEF FOR SURE . IT RAN ALL THE WAY DOWN TO .355 OF A VOLT . HERE IT'S RUNNING OFF A 1.2 VOLT RECHARGEABLE C CELL. GLOWING A BULB FILAMENT .     http://youtu.be/1YdLmgVf8x8



IT WILL RUN ANY LED BULB OR CFL WITH A LITTLE COAXING .

Fantastic!  I really love how you brought the input back down to 1.2 volts.  That is where we all started and now you can light an Edison bulb.....simply incredible.

Hi folks, Hi gadget, thanks for sharing your experiment results and videos, could you please share the amp draw results from some of these tests, thanks much.
Trying a ferrite e-core for this SJR 3.0, just wrapping around the whole thing like a solenoid to fit more windings, we'll see what happens.

peace love light

Well done... good results_while running your experiments though I would use a larger heat sink, you don't want to create a shortage of 2N3055's!!
