Joule Thief

Thank you!

If you look well to that circuit, it also has two NPNs.
I also use paint to make my circuits, then I convert them to jpg with irfanview program.

I have made some very, very crude drawings in paint.  Where do you get the electronic symbols from? Someone told me you have to copy and paste them but I can never seem to find all the cool symbols and component pictures everyone else seems to have.  Thank you.

On my circuit i wanted opposite symmetry for each side so that it would get the flow going from both sides of the cap and in from both sides as well, to create a self powered joule thief it will need some improvement, but the principle is to get it to self resonate then the pickup coil transmit voltage. So i wound the coil like the previous picture 12 turns each, i believe it was inspired from a Telsa patent, i found it in this forum.
I have built a few small practice amp and gt2 guitar pedals,i don't have much expertise on the subject but that never stop me from doing it.

We can't wait for a savior we have help our self first.Thanks for your interest.

Thanks again.

@ Bill i took the first jt circuit drawing i found at www.evilmadscientist.com

Take this file and save it as bmp and when you are building a circuit choose the symbol and copy it to memory,
paste it back on paint and resize it to the size you need by dragging the square handles.

Do the same with any picture you find on the forum. Save it as bmp and then edit it with paint using its own symbols.

To convert it to jpg use irfanview that can be downloaded free from the internet.

@Pirate88179,

I use Paint when drawing less complex drawings. For bigger circuit drawings I use Cadsoft Eagle cad.

In Paint there is no library of components. What you do is drawing each component you need in the
circuit drawing by memory. So if you want a transistor then use the Paint built in circle first. Then you use
the line to draw the inside of the transistor. Making a diode is easy, just draw the half of the diode copy
it and paste it. Then select rotate in the menu and turn the half upside down. Now you just move the half
against the first one and you have a diode. Do not use the pencil. Use the line, the circle etc. In a circuit
drawing, when you need more of the same components already made, just copy and paste.

You will be amazed how fast you can make a circuit drawing with a little practice. I also find the zoom in
and out feature very useful in Paint. Also the rotate function is very useful.

Groundloop.
