Joule Thief

[electricme]

@Resonanceman
Hello Gary, put an add in a paper asking people to let you have their preloved computer for $10 bucks, offer to pick it up for free.
Youll be surprised how many people ring up to get rid of their "junk".

Gadget 

Right now  I only have  T-Mobile for internet .
The  problem is  where I use my computer now  I am in an area with very poor reception ...... It  worked  much better  when I had a better signal .
T-Mobile is upgrading their  system  They  have a new USB   reciever  that  replaces what I am using now ...... PCMCIA wireless card ,

Unfortunatly   my income is  very limited  right now .......and  looks like it is going to get worse before it gets better .   SO   I pretty much   have to stay with what I have .     

If  things  get a little better  I will probably  get a  different  computer  and  upgrade to a  the new  T- mobile  system or a different carrier .

I am  using a notebook .......In theory  I could take it  out and  find a hot spot ......but  this thing is on its last leg
The battery is  shot .... The  fan is really noisy  and the  hinges are broke . 
I could fix these problems  ..........but it would cost me  about as much  as a mini  notebook  I have been looking at .

I just came back from the junk man, scorred myself a small UPS and a power supply with a see through plastic fan, picked up a 125Gig HD, all for $5.00.

Another way to get hold of redundant PCs is to do a "flyer drop" in a well off subburb, tell em you refurbish computers and need parts from others to rebuild em.

Once word gets around that you are a computer man, people will actually give you their old PCs rather than turf them out.

Go and visit your local council tip, see the head honcho, tel him you need a secondhand PC, and offer a few bucks to get one.

I just walked into the local scrap fella and said, hi fellas, I looking for a computer, have you got any? Back came the answer, shure, go down this side of the building, take you pick, there was about 50 in the pile, all sizes and types.

hope this helps

Jim:

I got 2 computers (so far) and one monitor out of the dumpster at my apartment complex!  People are always tossing away good stuff.

I am ashamed now and I want to apologize for my second failure. It seems that the whole thing was a lose connection. I will post no more.
I will not resist a third failure.

I know that the loop is there because I had it in front of me working and recharging the battery everyday to the same voltage while working the joule thief.
But I made a test adding a ceramic 104k accross the base resistor and the whole thing changed its behavior and worked no more.
I know that it was a bad connection which made the loop because I put solder on the joule thief legs and when I reassembled the joule thief, the LED stayed on no matter if the switch was open or closed.

I will let the task to find which connection produce that behavior to the young.

Again I cannot resist another public failure.

Hey Man,

Do NOT give up!! You are close VERY close to your goal. I have noticed on my self charger that the connections have an important part to play and I do not mean just completing the circuit. I tried to make better connections and lost my oscillating effect that seems to be the reason for the  charging of my battery's. 

I think it has something to do with resistance and load on the circuit when matched with the frequency that the toroid is resonating at. Try to unsolder your connections and place small v-resistors on each one so that you can micro adjust. Also place a voltage regulator on your AA to tune the circuit.

Then you find the perfect setup for charging. However what I have noticed as a side effect that it will also charge my source battery I am not sure exactly way but it is very good!!! However once it gets to a certain level the circuit changes and needs to be readjusted.

Keep it up! And thank you so much for all the wonderful diagrams.

Take care!!!!

As far as I am concerned, no apology is needed. Every one makes mistakes. I see lots of them on this web site. I think it is more importand to share than to worry about making a mistake. Hopefully, when there is a mistake it will be found by someone. Thanks for posting information about the error.
