Joule Thief

[gadgetmall]

@Mrmag and all My DMM all switch from mili amps to volts . for instance if i want to measure the Ma's from a dead Jt battery i just switch to DCA for Mili amps  and then  DCV for volts . Its the 10 amp Plug i have to move . IST is Measuring Ma's

@all
   ok a way to produce something usable from a joule thief . Has anyone tried that electro lizer  with a Fugi yet .

As a matter of fact, I have been planning that next. The 42k number keeps being thrown around for the jt with the 1k resistor. I don't know where that information was verified, but I am wanting to use resonance more than amps to make the gas. So, lets find a thread for that... Make a thread for that? I haven't looked for a while, but I don't think there is one.

All electronics has a peizo that resonates at 21k and I have 3 of them on my list. (now that mac is back home, I can buy some things over the net.)

Didn't Freezer have a video with a joule thief toroid style making bubbles?  It was linked here in the early pages, I think.

thanks, lets start a thread,

MrMag:

One meter is a Craftsman Digital (Model # 82140) and my other one is an Omega, it is out in my van so I don't have the model number handy just now. If they show up, here are 2 pics of my Craftsman DMM.  In the one pic, I am testing mA's on my earth battery, and in the other I am testing dc volts.  Note the plugs are in the same position on the meter.  I hope this helps.

It starts at a much lower frequency and ramps up.  The led appears bright, as usual, but I think that is because even at the lower "start-up" frequency of my circuit, it is still much higher than 60 or 70 Hz so my eyes see the LED as "on" anyway.

bill, I distinctly heard it go down first then up past the start place then way up.

I will check again to be sure.

@ Jeanna:

Actually, I believe you are correct.  I kind of hear a dip in the very beginning as well.
