How to Make a Portable Game System
Hi,i added 2 Leds, a potentiometer and two switches to make an reading/night light robot out of scrap parts. :D Thank you !
The Smallest USB LED
Fun little project! Worked great first try!

I hope this comment helps. Mine didn't worked at first but after some CRITICAL fixes: 1) Bigger toroidal and thinner wires. And MOST IMPORTANT 2) The transistor wired as shown will NOT work in many cases because Base, Collector and Emitter are NOT in the same place. You need to know where the BCE are and is recommended to see a diagram for this circuit. I used both ferrite core and transistor from a dead CFL and did the test with a "dead" 1.5v battery and a UV LED. My transistor was a 13002.

connections seems to be ok but leds negative side is connected to emiter transistor and minus from battery? I've meet sometime problems with ring toroid can't light a joule thief. Check other toroid ring and transistor fault if any. I've made a bigger joule thief inverter on cilindric toroid primary-45meters x wires(0,28mm) and secondary 24turns 0,68 mm over primary connections from secondary just like joule thief and I can light 3w-5w bulb leds from 1,5v battery over 4 hours light. Joule thief it's an easy schematic but any foult cannot make it work. Don't give up. Try harder. Cheers
Same as instructions. 2N3904. I used wire from cat 5 cable which seems thin enough but I could be wrong? - ihaveaplace
What transistor type you've used? - kyooby
Use a potentiometer 1k for adjusting brightness or even better 100ohms pot. - kyooby
