Joule Thief

[WilbyInebriated]

HI,I have been following this thread and love the way everyone helping each other and  working together.I would like to share with you what i have come up with.I have used a joule thief to power a pulse motor and 25 leds at the same time.The motor is running and excelerating as the cap charges up and the leds are nice and bright.Here are some pics,circuit and a video.

Edit Diode in circuit diagram is 1N4937

BRAVO! i was wondering when someone would extend it to this. props to you jonny

Bill was able to get an led to drink from a cap slowly over a 20 minute period...perhaps if you tossed an led into your circuit, you would get the desired slow release of power.

Just from using my 10v 2200uF cap across the LED on my JT, I think that it may have more to do with the cap than the LED. I think this because this cap will take a minute or two to totally be unable to produce light once the battery is removed. My 50v 47uF discharges and the LED goes out immediately. I could be completely wrong because I really do not understand much about this yet, but that's my own observation, for what it's worth

I tried adding a quick pickup coil to my existing JT last night using 22 or 30 gauge(I'm guessing at this) enamel coated copper wire. I think I just don't grab the concept of your pickup coil very well. I made about 12 turns and then hooked the ends of this to the + and - of a bridge I took out of an old PC power supply. I then connected an LED to the two inner pins and hooked a battery to my JT. The JT's LED lit like normal, but the LED on the new winding did nothing. So, I flipped the LED. Again nothing. What am I missing here? I'm sure it's something pretty basic. I am a beginner and it was late at night

Welcome to the forum

Nice rig you got there, and fancy running a motor and  LEDs all at once, nice pics also.
I am off to bed, got to put some zzzz in, its just past midnight, so I will take a look at your U Tube post tomorrow morning

You can all got to work while I sleep
