Joule Thief

How long will it run on a potato ...

This is a circuit I posted on the New Jewel Thief "Resonate LCR Circuit" Much less energy draw.... thread started by sirmikey1. There is more information there about it.

This circuit uses only 0.1 mA to blink a neon or LEDs. A 1.5 volt "D" cell flashlight battery is rated at 12,000 mA-hr. Dividing 0.1 mA into 12,000 yields a run time of 12000/.1/24/365 = 13.7 years . Of course the battery will probably leak before that. If using LED also use a 1N4007 diode in series with the LED to prevent the LED from being damaged by the reverse voltage.

Three videos of this circuit on YouTube at:

NOTE: It is not really a Joule thief, it is actually a relaxation oscillator.

Great improvements, I look forward to seeing more.  This circuit makes good use of a different approach to the basic circuit.

It's no surprise the draw is so low - unfortunately I haven't been able to find a 100pf cap, on top of this, the transistors i'm using aren't functioning the same as yours, but that's to be expected.

Silly Spaceman



I just thought  I would set the record straight.

You have made  alot of really impressive stuff ............but  that does not mean  you have given us  anything.

You forget  that most of us  do not have your experience  or intuition about these things .........so yes you have to explain things as if you are talking to children

You seem to talk  mostly in your own code.
You know  exactly what  you mean........ but most of the rest of  us are lost ............ tic tic boom
I can only remember 1 schematic from you ........ I think it was  for making a PWM from a 555

I would  love to know more about how  some of your circuits work........but I gave up asking about them long ago............because your answers are in code or sharthand .....they make no sense to me.

I do  berlieve that everyone  has potential for genius inside of them
I think  you have found that potential. ........
Just  because  understnding  and building these kinds of circuits comes easy  and  natural for you  that does not mean  that it is easy or natural for the rest of us.

You might  think about  not calling us  silly humans any morec........ why not  try normal humans   

Don't get me  wrong here.......I am not saying you are any smarter  than  anyone else here .......this is just your element more than it is ours  .......please keep that in mind.

I am like you ........ I am a genius in some ways........but I am also very dumb in many ways . The dumb  is what most people tend to see first.

You could be  of great help to the people here ......but so far you have been very little help

To  be  if great help  you WILL have to talk to  us like we are dumb .......without treating us like we are dumb
I need all the help  I can  get ....  I need the procress walked through step by step ........I need schematics

Once I can see it in my mind........then I got it ......  My mind is mostly  visual.

One of the ways I am a genius ........I am a peacemaker ........can you feel the peace?

Nice reply Gary, you are a lot more diplomatic then I. I started to write a reply to that post earlier this morning but ended up closing my browser without posting it.
Don't sell yourself and others short in this thread. Many have come a very long way with each others help. Many here started out with little or no electronics knowledge and now have a very good grasp of the joule thief and it's potential. I don't post very often but I have followed this thread from the beginning.

It is easy to come on here and talk in tongues, gibberish and make people think that you know what your talking about. People who have little or no experience can be easily fooled into believing this type of person. The people who do have some electronics experience usually catch on pretty quickly. It is easy for anyone to tell if these people actually know what they are talking about.

First, ask a question. Even if the person doesn't know the answer they will tell you that they are not sure. If the person tells you it is above your head or you would not understand, it should raise a flag.

Second, ask for readings. Most people will give you the input and output readings. They may not be completely correct but you will get something from them. The person who ignores your request is usually hiding something.

Ask for a schematic. I realize that a lot of people here have a rough time drawing a schematic. Any kind of drawing is helpful. The type of drawing that Kooler just did a few posts ago is probably the easiest to understand for most. (thanx Kooler).

Also, most normal people would say something like, "I think I may have discovered something" when performing their tests. Other people claim great OU discoveries before even building the device.

I could go on all day with this but I think you get the point.

One last point. NOBODY here is stupid! Some people here have more experience then others, but they too had to start somewhere. It really really bothers me when someone calls someone else stupid. It is their own shortcomings that cause them to say things like this. Never be afraid to ask a question when you are not sure. Someone here is always willing to help you out any way they can.

i do agree and i did not mean to offend anyone much less you gary!  BTW EVERYONE IS GENIOUS ! EACH IN THERE OWN WAY ..   im sorry that this is MY WAY!  at least i shared at all..... many have not !

here is MY npn MAGIC MAKER ....
