Joule Thief

[Mk1]

@all

Tonight experiments ...

First i made a jt out of a piece of copper tubing 1/2 inch diameter by 1/3 inch, did not work with out cap . Also planing the same on a silver and gold ring.

I also made a two toroid jt , stacked on top of each other, so the secondary goes around the two toroid , both toroid have one wire 12 turn and one the same wire one turn on the other toroid.

More later or if you guys have questions.

i did make a mistake ..

2.4 ghz ..

yes what you found garry will do just fine ...

the amp should go on the transmitting location ... it is an inline amp ...

any router will work as an access point ..  but you need a bridge .. to recieve ... 

i had this entire setup in my work van 4 years ago i had HIGH SPEED I NET IN MY VAN ...

ANYWHERE IN THE LOWER PROVENCE OF ONT .. I SIMPLY PUT A 2.4 GHZ  omni on my van roof ... amped it to a bridge ... i could suck signal from all routers all over the place ... 

never mine the over 100 access points the network i worked for owned

here is a rf amp 1 watt.. over 1 watt YOU NEED A LICIENCE .. TO BRODCAST!!!!!!!!

Thanks  for the help

I think I am going to  try it  without   the amp
The  amp looks  great .......but if I can   get a signal  without it I  have saved  a bunch of  money
I think  my first   choice  if  I  do not get  a  good enough  signal  with the  original  Yagi   would  be to duplicate  the  original a few times and make an array .
The   antennas do not  quite add up  1+1 =2    a  second  antenna   might  add 50% more  if you are lucky and very careful
All  the   coax  from the  antennas  have to be the same length

I am  thinking  that  an array  of  6 to 8   yagies would  be much cheaper  than  the  amp
If that is still not enough .......the amp should  drive the   array very nicely .




I  don't  know if I will be able to  put it up on the roof  here ......   
It is nice to know that it can be done  from  the roof  of a car if need be.

Wow Mark,
I was planning to do this next!

My plan was to wind one wire on each toroid and stack the 2 toroids so the magnetic 'currents' went in opposite directions.
I wanted to then experiment with ways to wind a secondary.

How did you wind the secondary when you wrapped them together.
Did you keep them together and go through the middle just like a single toroid?

I was also thinking I would put some tape around the outside to make a kind of edge support then make a wrap around the circumference of the outside of the 2 of them  and not going through the center.

Did you ever try that?

I am finished with my beautiful roof and ready to joule thief some more.
