Here is a few different set-ups!

Wow that's cool. I don't have any small diodes like you are using will 1n1004s or something similar work? I have been using 9 volts on the CFL driver is 5 volts recommended?

Thank you so much for the help!

Here is just a short video.I wanted to show that this circuit will charge batteries and still give off light at the same time.
It's running off a cell phone charger that uses one AA battery to bump it up to 5.5v.
It's lighting the 40 led's and a 20w cfl and also charging ten other AA batteries.

It ran for 4.5 hours before the AA in the cell phone charger died but it charged the other batteries up 13.35 v
After rest the batteries were 13v and the cell phone charger stops working at 1v.

Nice work slayer007! I have been charging batterys with my Joule Thief but it will only charge 1 at a time. i can run leds and a small motor at the same time as well.

Have you did any tests to see if your charged battery's are experiencing empty voltage? I know my battery's will charge to a full 1.33 volts but not last as long as if I used my wall charger but yet they get the same voltage.

Keep up the great work!
