This topic will be locked and display all of the circuits and some photos of the devices being worked on in the Joule Thief topic. This is going to take me a while to do so please be patient. If you feel there is an error, or I need to include something else that is not here, please feel free to im me and I will fix it. Thank you.

Bill

We will also be adding an index here if possible....stayed tuned.

Here is the visual difference from the outside of the camera. THE BOX IS THE SAME FOR BOTH!. I moved---sorry for the fuzz.

The AA has a push button and is a smooth rubberish button you hold for 1 flash or lift up the door for continuous flash.
The AAA has a green button with 4 bumps that you slide up into position for flash.

I hope this uploads.

Below are Jim's detailed instructions for making a JT. This will help many of the new folks here and possibly quite a few of the rest of us. Thank you Jim for allowing me to post these here. Also, thanks Gary for suggesting that I do so.

Bill

"I have been quietly reading (whilst eating all my Licorice) and are aware of your problem trying to get your JT LED lit.

Just like you, I also managed to muck up most of my JT's bigtime, and it drove me crasy and set me back for weeks.

I found I was making a very basic mistake, I was connecting the bifilar wires back to front.

Why, because this is very easy to do, and it really has never been explained in very clear instructions, so I stumbled around in winding my torids.

The circuit as it is drawn is correct, BUT, it is deceiving because if one dosent know the reason for the DOT at the windings, there is no way they could work it out. It is in fact a lasy way to draw the circuit, so the circuit can be presented to look nice.

If the bottom lead, of the 2nd bifilar coil was drawn with it's lead going back upwards to the top of the other coil (batt +), and the top lead of the same coil, was drawn to go downwards, then it would make better sence.

The 2 black dots, means these are the ends of the 2 wires (the starts) which you held when you began to wind your coil.
If a beginner starts to make a bifilar coil, using same size and colour wires, it will probably not work, unless it's a fluke, and if it will not work, then the coil builder is left with, WHERE DID I GO WRONG, there are 7 connections, which compounds to at least 7X 7 = 49 different configurations or mistakes that are possible.

The easiest way to learn to make the bifilar coil and connect it's wire connections is to first have 2 different coloured wires to start out with.

Cut 2 lengths of insulated wires, and put a small tag you can write on.

Lets say one wire is GOLD, the other is GREEN.

With the "start" wires, mark them Gold (a) and Green (a) NOTE, these have the BLACK DOT's on the circuit

OK, TIME TO START TO WIND THE COILS.

Wind, wind wind wind wind wind lol

The end Gold wire is marked Gold (b)
The end Green wire is marked Green (b)

Now connect the Gold (b) wire to the Green (a) wire.

NOTE (This soldered connection is where you feed the (+) Positave from the battery).

The other 2 free wires are connected to the transistor and the LED like this.

The Gold (a) wire, is soldered to the COLLECTOR of the transistor.

The Green (b) wire is soldered to the RESISTOR 1k ohm
The other end of the resistor is soldered to the BASE of the transistor.

Now hold the transistor with the flat face towards you.
The middle leg is the Base (b)
The Left leg is the collector (c)
The Right leg is the Emitter (e)

Now look at the LED, there is a FLAT edge at the bottom of the LED
Twist the LED so the "flat" edge is to the right

Solder the flat or right leg of the LED to the right leg (e) of the transistor.

Solder the free leg of the LED to the collector (c) of the transistor.

Solder a black wire which is the NEGative to the Transistor (e)

Solder a RED wire to the wires on the torid you joined together.

Connect the 1.2v battery and it should light up.

OK, I hope this has shed some light on how to make it all work."

Below is a quote from Sparks that I thought was important enough to reproduce here as it defines why some of us are still working on this thing:

"@all (Quoted from Spark's post)

The voltage multiplier circuit is great!!! All the EE's will tell you but there is no significant amperage and whatever. But there is alot of potential for some amperage to be derived from the little stun gun circuits being built.

If for every milli amp milli second you have a voltage multiplier circuit that raises the voltage on a variable capacitor 20volts: At the end of 1 second your capacitor would be up to 20,000 volts. After 2 seconds 40,000 volts. After a minute 1.2 million volts. Now short that capacitor out in say a millisecond.
Amperage in your circuit will be I=E/r Since your resistance is as close to zero as you can get it say .1 ohms. Amperage is now going to be 1.2million volts/.1 or in a miilisecond you are going to get a flow of 10.2 million amps. This was from a flow of 1 milliamp for 1 minute into your system. Lets break that 10.2 million amps for one millisecond down compared to your investment amperage. Input 1 milliamp minutes Output 170 milliamp minutes. There is a gain of 169 milliamps per minute or in one hour you have some extra work of about 10.14 amp hours. If your 10.2million for a millisecond discharge is invested in some reactive energy system that allows this discharge to oscillate for an hour instead of just flowing for 1 millisecond you can see that your voltage multiplier circuit coupled to the proper capacitor and resonant circuit can get very powerful very quickly. 10.2 million amps flowing in a resonant circuit for an hour is sure to let the near field get excited more than lighting up an incandescent bulb with the same investment wattage."

TheNOP's toroid permeability chart:

The permeabilities or in this case AL factors i.e. ( inductance per 100 turns2 ) are:

TYPE COLOR AL Freq. Range

T50-26 Yel-Wh 320uH power freq. <--- 0 kHz. - 400 kHz i think
T50-3 Gray 175 50 Khz to 500 Khz
T50-1 Blue 100 500 Khz to 5 Mhz
T50-2 Red 57 2 Mhz to 30 Mhz
T50-6 Yellow 47 10 to 50 Mhz
T50-10 Black 32 30 to 100 Mhz

There is no standard color code for toroids.
Each manufacturer does it his way.
The color codes for iron powder cores shown in the ARRL handbook are for cores made by Micrometals.

for those made by Amidon see this link:
http://www.uoguelph.ca/~antoon/circ/toroids.htm

to me, with a joule thief, it is almost impossible to saturate a pc power supply toroid.
the current and frequencies we seem to get are too low to do that.

if it work with the led at standard place i don't see why it stop working for a third secondary coil.
unless...
reading 0.00 Volts might still be because of your meter limits.
the hemf are polarised, try your diodes both way.

Here I will be posting our sources for supplies and components to build the JT circuits.

I will add them and then folks can find the large toroids, transistors and other items used in our circuits. We are not endorsing anyone here but these will be the suppliers we have found to be reliable and also the ones that offer decent prices for these items.

Stay tuned....
