Joule Thief

@ Jesus,OK, try a 12v tail light, globe, they are designed to work better than a 5watt resistor, and can handle the heat very well .

Thank you @electricme !  I will try that or a 12v led I have available.

@all

I made it work. The first tesla coil joule thief!!!!

It only works if the winding direction is opposite to the secondary's winding direction.
Also just if the secondary winding is at the collector and the primary at the base.
That was like @jeanna and @xee2 way of doing it.

But there is still another detail, it only lights the led if there is a small switching diode with the cathode to the transistor's base.

In this case if I put any other diode at the base it wont light the led.

After taking some photos I disconnected the battery for a few seconds and took another shot with the battery recovered and the led was brighter.

@stprue

If you can, do this test:
1. Unplug the power supply from the wall
2. Connect a jumper from the power supply plug ground to the wall receptacle ground.
3. Connect your circuit to the power supply as usual.
4. Check with voltmeter.

Good luck!  This is important for all of us. If you succeed, we succeed.

Maybe I won't give up on it yet, but when I turn the power supply off....no more voltage.

Jesus:

Way to go man!!  Very nice work.  I am glad you stuck with it...see...your persistence paid off.  That is a very nice looking Tesla coil and now, it is lighting an led.

Excellent!

@ All:

Slightly off-topic but maybe not really since we are all interested in energy.  I just got my electric bill for the month of July here in Kentucky and it was $31.00.  Now, this includes taxes, both state and local, AND a mandatory $5.00 recycling fee charge.  I think that is pretty good!  I did the same energy management type stuff at my other house and after 6 months, the electric company came out and replaced my meter.  When I asked why they were doing that, they said it was because the last folks that owned it had electric bills/power usage 250% over mine so the meter must be defective. Funny thing, my bills stayed at the same low levels.

When I moved in here 7 years ago, (small apartment) I got an electric power usage history from the company that showed the bills averaged $80/month year round.  That was long before the recycling fee and at least 4 tax increases.  My goal is to have them come out here and replace my meter once again.  When you light your home with leds from dead batteries, it uses less power, ha ha.

Just wanted to share this with you folks.

Unreal  bill Bill NC Charges 45 dollars just to keep the service on with no Electrical Draw . Mine was 240.00 for July . I have powersaver installed also and half of My house Circuit is Solar . Without all that My bill would be about $400.00 plus so I'm saving almost 50 percent with the energy Devices . .. Most of it Air Conditioner cause the temp haven't got below 95 in the shade . most of the time its 98 -99 f outside and about 78 inside . I want to make Cold from Heat . One of My Projects on the list and i have the Plans on My Plans Disk for an Ammonia freezer using the Sun . I also have 4 Solar Heating panels for the Winter i haven't hooked up yet . they are nice . i can fill them with water and get Steam in a minute . But anyways that is one low light bill . unheard of . I hope to install My 40 foot tower with My Wind generator before the Years out . the hole is dug just need a few tons of Concrete to fill it . once that happens I'll have 80 amps at 24- 48 volts to power 12 volt water Heater  Elements and Inverters running from 1100 pound Fork lift battery // I could do better . lowest bill was before the heat cam 61 dollars in march .
BTW Great Work people on Eb electricme . Series is a first in the dirt !! Good job . And also the other Friends here are hammering out great stuff never before done . Wonderful !keep it up and soon you will Discover what i did and beyond . there is still the Current amps we need to increase . your on the right track with Hv the next step is then to reduce that voltage down and the current should be very high .
Sorry i haven't much to contribute lately . So many things happening (all good) that i have little time for the internet this summer . I have accomplished a lot and when i get the time i want to share My finding . Number one HHO from Joule thief's heavy output . Ou Bedini made simple with standard parts  as well 5 circuits to make a selfrunning Jt / battery charger . Its can be done . just get the mill amp draw to the minimum .
I get Lost in all My Discoverys if i try . Theres nothing like having an Ou device in your home to show off even it does nothing but produce light and motion on a small scale . I dont have the watts for the Ou prize i want but i'm working on it .
