DIY Joule Thief Mouse Led Flashlight

it should as long as you fit the wire around the ring withought overlapping them there realy isn't a magic number though just wrap it till you get all the way around the ring,

would 17 times work or 16 whats the magic number of turns

if you have lots of like in your mouse case you may want to consider upgrading your joule thief circuit with a capacitor and a more efficient transformer
google "talking electronics" and "joule thief"

Thats a good idea, yea I have one of those too the thing is you don't want the wires to be wrapped more than 18 times for some odd reason it works better when you have less wraps, try it though it may be differant then the few that I got, I tried mine and no go so I had to re wrap them.

the one in my digital answering machine has 4 leads but it might be a transformer but it looks almost like your joule thief in your vid, and I do have an old PC power supply i can rip that out of, i have wire from an old transformer will that work i think its coated i can find out with my pocket blowtorch, just burn the wire if it flames up then its coated, i use this method to remove the coating from the wires of headphones when im fixing them

Yea type in make a joule thief on here it will tell you all you need, about 1.5 to 2ft. resin coated copper wire works better than what they use on thier vid though. you can find this wire wrapped around the ferrite wheel in a power supply unit from an old pc.
the one your talking about is similar but you actualy only have two leads comming off of it you need to have the four leads.

Jim I opened up a telephone/answering machine and inside it i found a coil inside and the core looks just like in your video but i need to figger out how to run this thing off DC first (the answering machine) b/c i need that core so i can rehack my computer mouse like you did I just need wire which i have plenty of and what else a transistor and a white LED and a 1 AA battery holder

Your right coondog I should have put a battery compartment in there but they do last quite a while I have let an led go on a joule thief for two weeks continuous on one AAA battery. the parts you can get at radio shack dirt cheap.

comment limits S**k , 4:27 you should just use a 1 AA battery holder so you can change the batteries easier when they die or do they last so long its crazy, i think im gonna rehack my mouse flashlight and do it this way but i need parts

awesome video thanks for the buddy mention, i enjoyed making this flashlight on my video, the wires on my mouse were hardwired but i just ripped them out b/c i was cutting the board anyway and i need a resistor in my mouse light b/c the LED has just about burned out,:59 I wired all 3 switches so they all turn on the light, 1:56 i actually did all this just i didnt show it b/c i dont have the right facilities to record

Hey that was cool
