Joule Thief

[jeanna]

A ufo and a joule box. (edit nice gadget)
What a wonderful showing  to draw an end to this year of amazing accomplishment!
Good for us all!!!

I managed to get the 300v toroid to shut off at the switch... I think...probably.
I will wait and see if there is any draining, but it appears to be good.
There are storage caps in the unmodified bulb, and when I had the 700v JTC running the lamp, the storage caps kept the volts alive and they must have been arcing at the switch which made the switch useless for turning the lamp off.

Today I used a smaller toroid and a higher base resistor which made the total be 300v/ The unmodified bulb is not as bright as with 700v (duh) but it does turn off at the switch.

and a pic...

I need to find a container for the joule thief whose secondary wires go in through the top and whose battery is connected at the bottom and which hangs down.
there were no shades at the thrift store, so I might get one for this purpose. I need to hide the snaggle of wires.
I'll show you...

I should probably add that a switch made like Bills would be the solution in the use of the 700v toroid.
This is because Bill's magnet switch will disengage the battery.

Nice LEDs.    Kroger store should be selling their left over LED xmas lights for about 1/4 price soon.   I purchased a string of 100 for under $2.00 US last year.

@ xee
nice joule(r.e.) box 

@ jeanna
a mini keg would hide those wires great probably not the decor you're looking for though...

@ all
happy holidays. may your next trip around the sun be your best yet!

Gadget:

You are correct, this was the same time last year I got all of those 100 led strings for like 1/3 the price.  good find.

Xee2:

Nice box!  I like clear boxes that show all of our hard work in winding.

Jeanna:

Hey, you might have to take your light apart but, a PVC tube of about 2" OD would slide over all of your wires and hide them completely.  Or, a paper towel tube cut to length and painted white, or off-white would work also.

My magnets are only used to attach the battery to what ever size battery I want to use, I do have a "normal" on/off toggle switch on the side of the box for turning on and off.  I have to admit that I do remove the battery from my Jeanna Light when it is not in use...just in case.  I guess I do not trust my electronics skills that much yet.  I don't want to be off working a case and be worrying about something shorting out, ha ha.  My cat, smart as she is, does still not know how to dial 911.

Amazing. I have never been able to get an unmodified CFL to light. What bulb are you using?
