Joule Thief

Hi All

I decided to create a separate thread for the Fuji mod, hope you all don't mind.

I hope that we can all come together and create a CFL driver circuit that everyone can create and use

Regards,
Paul

@ All

Well the first Fuji barebone test circuit was successful, now lighting a CFL from a single AA battery! 

See http://www.overunity.com/index.php?topic=6933.msg161181#msg161181 for photos.

I'm not currently doing any mods on the original board so that I can test different transistors.

If it lasts a couple of hours I'll move it to thread 1 as a successful easy replication.

Thanks Al et All 

Paul

@keon1

im working away on my 6pac toy i will have new pictures tommorow i have finished the supply board ... i cut back on the rechargable batteries... im only chargeing 2 now ... seams to work ok..  it does charge much quicker with 1 aa

it is all mounted and working well it keeps the 4 3.6vdc batteries toped up ...

the 6pac is allmost all wired up ..... down to 6 wires in and 60 out ....  it is not mounted yet ..

or tested ..  all rings work and put out 24 feeds of 100vdc  i dont know bout the jt feeds i have not tapped them yet ...,

@bill

im gonna list prefinished flashlights as well as kits...  for a number of diffrent flashlights...    i currently have a small silver one im modding right now... 

there was a problem with the first one i did and i did not mention it     yet ....  it needs to be switched ...  cuz it will drain the battery when the leds are not being powered ...   THIS DID PROVE TO BE A PROBLEM ....     but that is ok ... for that mod ...     i will simply add a small switch to the ring .... but i dont like this to sell it AND I DONT WANT ANY WIRES CONNECTING ANYTHING ANYWHERE .......


SO

now you have to open up the darn thing everytime you want to use it and flip the switch to turn the ring on ..... 


still something i dont want to sell .....      so ... i sat down with another small one    it is just a bit better ..

i solved the switch problem TOTALLY    no wires...  so that is good news .... 

now i can sell my kits modded or  do it your self kit ... 

so they will be for sale soon  THE JT DEAD BATTERY FLASHLIGHT ...

no idea what they should sell for ....??   tho ...  hummmm   ideas?

any how when i compleat the SIMPLE SOLUTION MOD I WILL POST HOW IT IS DONE ...

now my ring turns on and off with the orginal switch ... aswell does the leds without any external wires... 

ist!

@ All:

I had an idea so I am going to try it.  I started a topic...Joule Thief Circuit Diagrams,etc. here: http://www.overunity.com/index.php?topic=6942.0

This is a locked topic but it will eventually contain all of the circuit diagrams posted here for easier reference for folks.  i may add some photos as well.  this will be so anyone can look and find the schematic they are looking for without having to wade through all of our posts.  If I have a wrong diagram, or if you feel I have left some out, please tell me here, or im me and I will fix it.  It is going to take me some time to go back through all of our posts here and pull out the technical stuff, so please be patient.

I am doing this in the interest of providing fast access to all of the technical information we have built up over these past few months.  Also, please feel free to post here, or im me, with any additional stuff you think should be included.  Thanks again to everyone for making this topic so enjoyable and informative.

Bill                 PS  I had wanted to do something like this for the earth battery topic last year, but never got around to it.

@ Pirate

Good move on your part 

The transformer pin numbers don't match the circuit at http://www.overunity.com/index.php?topic=6942.msg161198#msg161198 , this was noticed and corrected by RAF if memory serves correctly, which post way back I can't remember.

Here's the link to my interpretation of the Fuji transformer pins http://www.overunity.com/index.php?topic=6933.msg161181#msg161181

@ Paul:

Thanks.  it is early yet for getting these posted and I am sure I will have more outdated or revised diagrams as I go.  Thanks for pointing this out.  I will make the change.
