Joule Thief

[Pirate88179]

i saw something similar on instructables, it was featured in their 'get the LED out' contest.

an egg makes a nice diffuser also

have you tried adding bleach to the water like those guys in that thread awhile back. http://www.overunity.com/index.php?topic=4878.0

here are a couple nice JT projects kids might enjoy.
for the boys, http://www.instructables.com/id/Electric-Chair-Joule-Thief/
for the girls, http://www.instructables.com/id/Cat-Burglar-Joule-Thief/

and here is another 1.5V to 350V inverter.

unrelated but one of my personal favs among many on instructables, flaming mini-marshmallow projectiles get me every time...

@ Wilby:

Sorry I missed the question about the bleach.  Yes, I remember that topic which is what gave me the idea to do this with the plastic water bottle.  I am sure it has been done before by many but that is where i got the idea.  As far as the bleach goes, I believe that was only added to the water to keep it from going bad, and I will do the same if I settle on a final design and seal them up for good.  I could be wrong here, but that is what I thought he used the bleach for.  Thanks.  Here is the photo from instructables with the light bulb filled with broken glass.  Now THAT is a good diffuser.  I am going to try it in the plastic bottles.  Thanks for finding that and posting it.

@ Freezer:

Are those neons?  Nice work!!

Bill

Thanks and yes, they a Ne2 colored and 1 regular Ne2.  The great thing about this is that its already built, all you need to do is remove some components and solder some on.

@Freezer,

I have read about the Stubblefields battery but I have no idea on how it worked.

A friend of mine paid some money to call Mr. Thrapp. His impression was
that the only thing he was interested in was getting more money.

Great JT you made.
Groundloop.

Thanks, yea, you can hear in each one of his interviews that he doesn't want to talk about anything, and that he's interested in the money.  I still think he knows how to do it, but not willing to share that information, even if you do pay him.

I made small video for youtube about this joule thief. Added a 3 way switch to go between 2 neons and an output plug.

Found another 23w fluorescent bulb and it lights.

@freezer
nice build!

@wilbyinebriated

Is the joule thief running with the current drawn from the air?
Because I can see something that seems a battery there.
If it is running with just the crystal radio generated power. Would you be so kind as to post the schematics or circuits of the components configuration?
I would like to replicate it.
Good Job!

you got me thinking jesus...
i don't think you could place a joule thief in substitution of the ear piece on a crystal radio and have it work. i'd love to see it done although i'm pretty sure you wont get enough amps from a crystal set. but... i don't see any reason why a crystal radio itself wouldn't light a led. try replacing the diode in most any crystal radio circuit with a led. i'd be willing to bet with a good (100-200ft) antenna,  a good ground and of course a strong (50K watt) station nearby, it will light.
couple things come to mind, pick a low current led and use a crystal circuit design that will step down the voltage and raise the amperage, like the coil i showed previously. then again, if you aren't nearby a strong station, a crystal set with less selectivity might be a better choice to try and light a led.
hurry hurry, i might just have to beat you to it i'm just waiting on the variable capacitor, because i'm too lazy to just make one. here is the circuit for the coil i showed with the joule thief.

Very impressive video!!  Nice work.
Can you share the details of your modifications?
I want to replicate.
