I would suggest the MK1 JT circuit.  You can add a bunch of leds off the pick-up coil and not up the Ma draw.

Bill

Bill,

I tried to find the MK1 JT circuit, but i failed to find the schematic.
I searched this forum by user MK1 and keyword joule and jt and thief, but no luck  ???
Can you point me in the right direction?

Regards,

Flux

Here are a few.  you can find these, and many more in the JT diagrams topic area.  It is a locked topic I started to place schematics and photos from the large JT topic area.

I hope this helps.

Bill

Hi bill,

Thank you for posting those circuits.
The 3th one looks interesting, but i fail to see where the leds should be on that one!
Yesterday i build koolers BWJT with 5 - 11 turns and a lot of turns on the secondary (75 - 100). Changed the cap to a 471 instead of a 104. It's drawing between 8 and 16 ma and lights up 3 superflux leds. I chose for 16ma draw because leds are at full brightness and that's 33% less draw as the original jt circuit from the factory (8ma for 1 led). Further more these superflux leds are rated at 30ma each in stead of 20ma.

Regards,

Laurens

I finished my solar garden light today.
Thank you Kooler for your help.
I will post the solar circuit tonight or tomorrow, i made my own circuit in stead of using lidmotors circuit.
I have a new laptop and need to install software to shrink the pictures first.
Also i will take a tew foto's tonight (dark action foto's).

As promised here are the foto's (circuits included).


Joule Thief Circuit (by Kooler (just adjusted it a bit).

The Solar "ON" "OFF" switch circuit i thought up.

And some building PICs and a test action foto  ;D ;D



If someone has a better Solar "ON" "OFF" switch circuit please let me know.
The circuit works, but there is a downside with it.
When you have tuned the JT to the right amp draw vs light output and you hook up the solar switch circuit the LEDs turn a lot dimmer.
When i tested the JT circuit the LEDs were blazing at a amp draw of 16ma.
But now the LEDs are dim :confused:
If anyone has an idea i would like to hear it.

Regards,

Flux
