Joule Thief

@ All:

Yucca posted this link over on the Kapandze topic and I thought it might be useful for some folks over here.

High voltage resistors are expensive and he said this link shows you how to make an adjustable one for free:

Water resistors are wildly dangerous..esp this design, potentially explosive given a long delay, as well as capacitive with potential to create current.

@Bill
Sorry about this late reply, so many things holding me far behind now, I only up to P822 and just found your post now.

Jim:

I have always thought that a very well tuned Bedini could run on caps alone....no batteries.  Now, I have never done this but, with the advent of supercaps, I believe this to be totally possible. Supercaps, I think, will store those spikes and make them readily available faster and more efficient than batteries will so one could take a cap and precharge it and then run the motor and charge the second cap and then use a auto switching device to run forever.

I have a lot of ideas and not that much knowledge and even less funds.

Off-topic:  I am now working on a motorized bicycle that will get over 150 miles per gallon and will go 35 mph.  I ordered my motor tonight and got the bike a few days ago.  I can use this in my legal document delivery service. (Process service)

Bill

Any motor/electrical device will run forever, only trick is to be able to match its comsumption of energy, but if the output is higher than its input, then you will have succeeded.
A lot of people have managed to find this sweet crossoverpoint.

Bill with this motorised bike, you should enter the Tour De France, he he he.
I can picture it now, much burning rubber, lots-a thick smoke, great big trojan batteries haningin from the cross bar, a set of 1000watt flood lights purched on the ape hangers.
Each wheel fitted with duel disk trucky air brakes, an a big 3 phase extension lead to powerup de batteries, where does it gets its charge from?

The humble Joule Thief of course.

I think I have lost it in the top paddock chaps, a bit like spittin in the wind, lol it flys back and sticks to you.

Ohh boy time to go to P824

try rechargeing on the NEG side ..


have you ..  in the past?

i have been able to recharge both pos and neg in the past

i was useing a dubble supply battery when doing this ... like bedini  also when i was messing round with that style setup i got zapped a few times   and i mean ZAPPED  far more than 24vdc and im not talking a little kiss from hemf or colapseing effect im talking like putting your finger in the socket...

I STILL DONT KNOW HOW I DID THAT   but thats ok cuz it HURT!!  LOL

I dont know if today this post will go through. I have been trying to post answers to posts directed at me but have been unable. It seems that the forum is successful at the moment and cannot handle the amount of people that are interested at the same time.  Great forum by the way!!

I saw your post of the multimeter and it is out of reach for me.

The pulse mortor is still running. It was all night long flashing 2 leds connected between the collector of the transistor (with a diode and a resistor for the leds) and ground.

In the morning I saw that the leds were discharging the batteries and disconnected them. The batteries risen to 3.64v without the leds and then went down to a stable voltage of 3.45v.

I am discovering what is the secret of this behaviour and if it is what I think you wont believe it when I tell you if the pulse motor keeps running at least for more than three days.

That was the record from the other one before I disassembled it and could not get the same behaviour after reassembling it.

So I will test it for 2 more days and then I will disassemble it and reassemble it and if I discovered what it is, it will work back as before self charging.

Great work jesus.

You might try hooking up the led again and disconnecting it over and over to see what effect it will have on the battery.

All the best.

@all

If I try to answer a personal mail to me, there is an error screen all the time that says that the page cannot be reach.

Then if I try to quote a post there is another error shown that the page is not available or something like that.

I copied the message from my PM folder and will answer it here.

Hello Jesus,
I'm really happy you have managed to get my little extra bit of circuit suggestion to work for you.
I had not tried taking the JT out of the circuit.
Very interresting this.

Im of course referring to my pencilled drawing I posted about 3 weeks ago, upteen posts ago lol.

Could you please send me this circuit exactly as you have it connected and running.

hooroo Jesus

jim

I will post the complete circuit in stages at the feedback to the source topic from the beggining to the end after I finish the 2 days test.

The test consist on seeing that the pulse motor is still running and self charging.  Then unassemble it and reassemble it to see if it is really a self charging circuit.

You will be amazed of how a simple capacitor changed the whole thing to self charging.

Jesus
