Joule Thief

@ All:

OK, once again I am showing my ignorance. (I am getting used to it)  When I posted about the Fuji circuit using 1,240 mA's, I based that on testing the battery I used by itself.  I figured it could not draw more mA's than the battery had in it, which is probably true.  Now, if I wanted to test on how many mA's it is drawing while lighting 400 leds....how would I do this exactly?  If it was using less mA's than the battery had to offer, then my numbers of mA's per led would drop way down I would guess.  I really have no idea how to measure the current draw when connected to all of my leds.  If someone tells me, and I have the stuff I need to do it, I will do it.  I just figured that with the heavy load of all those leds, it would be using everything the battery had to offer.  Once again, I may be wrong.  Thank you all.

er Bill you put an amp meter in series with the battery . the meter i used had 2000ma 20ma and 200ua . My little Fugi power pack put the meter in OL on the 2000ma using a new Metal-Hydride 1.2 volt battery with 2400 MaH . Now i lowered the input current By putting a 680 pf cap across the base resistor to coil and got it down to 1900 and some and i think this can be got even lower with a variable resistor (pot) in series with the resistor by the transistor . Also i Might add that this is factory made and don't count in the Who can get the Lowest ma draw Contest  But this Fugi is VERY important .and you win the who can light the most LEDS with a 1.5 volt battery so far !! SOMEONE needs to wind a homemade fugi Toroid . I understand that was Mk1'slittle Contest .Who can Light a tube up First with a homemade coil . When that happens then i think Further improvements can and will be made to reduce the input current to light 1000's of leds for less than 1 ma total . Just a guess but because this is "cold Electricity and you can light up a string of 100 with one wire then it make ggod sence that this is Different electricity than a regular Jt . Its something More .

my sg coil is almost done   NO!! that does not stand for school girl ....  lol

i only used 6 coils ... but it is verry kool


ist!

Better reread that GM...you will see that my mule is named Friday...same as your horse.

And I think my mule may have been around longer than your horsey.

Finally got the neon to light up using a coil.
