Joule Thief

[gadgetmall]

ROBBIE!!! Good to see you . I know all about those spacial diodes .I cook germaniums with barium t in the tops of can transistors to change the gain.  where have you been dude.. Hey lets kill that jouleringer I have a theory that the coil is a delay line and in part the cap he used is depleted right at the start then the delay line coil has enuff storage to keep the transistor oscillating  and then source recharged in a second by the CFL wire and repeated until the sloped voltage is to low to keep the bulb lit then the current stops flowing to the cap  and it dies... Thoughts on it ?.you still got my number ? it is still the same .  . And you hit the nail dead on . . you can buy 100 of something and only a few work . Exactly what i found and sure others experienced that . Even in Cores they are not exact in a batch.

Hi Robbie

You have me wondering about what you have said....


"the reason i would use a cooked diode that worked in the 5-8 volt range was i could steal the energy being made by the circuit and not the battery..
i sure you have seen my cooked diodes in some of my videos.. i always put a small piece of blue heat shrink over the glass after i cook them so i dont confuse them with regular diodes..

When you say "cook them" do you mean heating them in an oven or something similar?  If so, at what temperature and how long?

Could you please expand on your knowledge gained so far, please

Thanks,
Paul

hey gadget,
good seeing you .. been awhile. it is real good seeing you folks still working on things.. when i was messing with the first jouleringer that run on a cap.. right before my scope blew i noticed that all it was happening was the transistor was being abused.. when the transistor cut off the bemf volts exceeded the transistors volts rating and blew pass it back to the cap but since the current was so low it took alot longer to kill the transistor..  and with the cap across the resistor to base of transistor we got two pulses for one..
i have been thinking lately of doing something with these ul listed led bulbs, all of mine have small step down transformers in them.. like pulsing the trans in the bulb rather than hitting it with HV .. but thats just thoughts.. i haven't done anything lately hoping to get me some energy so i can work on things like this again..

   I thought that if I mentioned your name, you might take the bait.  Ha!  it worked. Good thing too.

   I just fried my Exciters transistor, so I put another on, and like you said, the new one does not work  as well.  Good thing I buy them by the kilo. Should I toss that one in the oven_  might work better.
   At least we know that a self runner is possible, I would still be into trying.
  Good to hear from you.

hey goat,
the last time i cooked some semiconductors my wife made we do it on the grill.. she said if it isn't food don't put in the oven..
she got mad at me for cooking cdi boxes from atv's in the oven..
seems to me from the temp gauge on my grill outside the sweet spot was around 500f on the last batch .. i put them on a metal pan run for 8-10 mins..
i know thats not accurate numbers but it is a hit and miss game..

hey nick,
good to see you ..  i never had a self runner or a overunity device if i could get it to run on a cap alone would be awesome.. alkaline battery will take voltage hit and store it better than a rechargable battery but alkalines are short live when charged a few times..
the reason i had long runs with a couple circuits is when a alkaline battery get low like 0.2 volts we think it is dead right.. but no it still has alot of current left in it.. all you have to do is trick the transistor in to thinking it still has over 0.5 so it can turn on the base and a little extra to saturate the collector and emitter..
alkaline battery has the current but no volts.....
the reason my batteries started leaking was from over use which i found out later is the same as over charging..
but with nicad rechargables over use will not cause leak just over charge will the same with nimk and ni-lon..
a good test to show is my solar lights outside by my sidewalk had rechargables but died so i put half dead alkaline back in them.. they will out do those rechargables.. light is brighter and runs longer but it dies in a month battery leaks out.. same thing in my circuit the alkaline that a small charge runs months were i could not get a rechargable to work at all.. theres no secrets with me just tricks of the trade 

i got alot of old stuff i need to shoot a video of.. you guys may find interesting .. maybe soon
