Joule Ringer!

What i find interesting is that with the aircore the amp draw increases with each bulb, whereas with the SJR 2.0 the amp draw rises and plateaus.

This is right in line with my findings.  The only way I could find to light up ten LED bulbs super bright on low current as I show in my video was to use my largest ferrite E core and bell wire.  I think the phone wire would be better suited to the smaller E core that I give the link to on laserhacker.com.  I would really like to try a super huge ferrite E core with a much larger gauge heavy insulated wire.  I think the results would be amazing!

In my feeble attempt to replicate Lasersaber’s SJR, I did everything wrong and it still worked.  While it did not work well, it did light 2 120VAC LED’s.  The E-Core transformer was way too small.  It was one salvaged from some junk electronic (printer I think).  I used stranded CAT-5e wire and was only able to get 6 winds primary and 60 winds secondary and was barely able to close the transformer.  I connected it as per Lasersaber’s diagram posted on his website and it fired right off using a Lights of America 2 watt bulb running very bright.  Added a FEIT 1.2 watt bulb and both bulbs lit, the FEIT was very dim though.  Connected only the FEIT and it was very bright when ran alone.  The source was 12 volts and the current draw was ½ Amp, the 2n3055 ran very warm.  I will not try this one again until I can get a better suited core and the correct wire.

For lighting a single LED bulb, it is hard to beat the circuit posted by Xee2.  This circuit uses a RadioShack transformer, 1 transistor, 1 resistor, and 1 cap.  I have this connected to the USB port on my laptop and power it up several times a week for the last 5 months.  At 5 volts it only uses about 150 mA and runs cool.  I have the transistor on a heat sink, but it is not required.  It runs very well on AA battery as well.  This does not handle multiple bulbs very well though.  Here is a video of that build.

On my AIR CORE â€" Lynx Joule Lamp, I have not changed anything until I get my light meter in to check bulb brightness.  I very much like the CFL’s for light distribution over the LED’s even though they might not be as environmentally friendly, plus CFL’s are very cheap in comparison to LED’s.  For fun, you might try this, suspend a CFL in a clear plastic jar or glass canning jar and fill with mineral oil.  The effect is really cool.  I would only do this on a modified bulb though.

BTW: thanks Lasersaber for the “Low Power Joule Ringer”.  I have replicated this and have a couple running at the moment.  They have been running the light 24/7 for over a month now on an AA battery.  In the picture below, the black project box holds this circuit.

LaserSaber:  How big an E-Core would you like?  What would be your goal for performance? Are you looking to drop power vs light output or just light more bulbs? 

Incidentally, I have a very large Ferrite Torroid that weighs 3-4 Lbs.  Its 4.5" D x 1.5" thick.  I believe its gapped around the circumference with a plastic piece between two Torroids.  I'll see what it can do.

I never knew how much useful junk was in my shop!
