Second Stage Joule Thief Circuits

[gadgetmall]

This problem is an engineering problem which can be solved by some electronics, no? I think the big focus now is amplyfing this effect. From hours for charging the bcap to a few seconds. Then these can start heating homes. There's no need to hold back or be shy. IST seems to be heading into this direction too.

Well Yes  Ist is heading into House voltage using Inverters ,i Think . But for now this little project for the ou contest wont . It might keep your hamster nice and cozy in the winter or summer   Or maybe a well insulated Dog house .you will need a good 2 or 300 bcaps to heat a home . And that might be an option for some if you think how much you pay in gas and electricity verse . Also there is no way to charge these caps up in seconds unless you got access to a 200 amp charger . I have already burned out a good 10 amp battery charger trying to charge one up .Had it for over 10 years     They require a Constant Current supply as battery Chargers see them as a Dead Short ! We are doing good to charge them up ANY with an AA battery and a JT . And so i have been trying various Coils to cut the time to charge down and if you guys have the time i woul dlike you to measure your Input and output current on your Jt circuits using a 1 volt source . I am getting 5-6 Milliamps off the 2n2222a  C E junction . None off a secondary so far . only volts and Microamps . These caps like current and eat it up in a big way ,by storing it and amplifying it .

Thank you @gagetmall and @jadaro!!

We have a simple comparator voltage decision to solve as simple as possible on our hands here.

The need is to have the device to give a shot to fill the 1.5v and then stop and wait for the next shot.

I think that the solution is to build a circuit parallel to the bcap circuit, sharing only the negative.  It will have its own flash cap to give it its one shot and stop.

You know that it can be make to work four different ways of turning on an led with the same 1.5v. I did it once with three.

With that idea in mind, the circuit to be added can be designed.

Thermo switch may work, ..they cut of when they reach a certain temperature, looks a bit like a diode.

edit; I apologize this is a crap example, i don't think they're fast enough, plus they take time to turn back on...often more than a few minutes.

@Gadetmall,

It might keep your hamster nice and cozy in the winter or summer

What if you have a 10,000+ square foot hamster cage?

No one has ever won the human race but, guys like you and Gadget make it fun to watch. (An adaptation of a quote from Kinky Friedman)  Keep on keeping on guys.

the ones that i have and i have 4 of them are 12vdc triggers ..

they are 3 phase ac ss relays up to 500v 40 a or something like that ..  you go tic it goes bang bang bang

ist

gadget this is why i ordered and designed by 6

i could use 10 on the output.. so as i have more amprage  still 12vdc ..

im almost finished mounting the 4 ring unit to a plastic square .. i will make this so i can better study what is going on in this unit ...

i just drew up the digram .. by hand all seams in ordor i see no reason this will not work ... if there is .. then i will find it ..

materials 4 goldmines 1"
2 28 ga magnet wire .. 7.3 grams each
2 14 ga 15" long 8 turn magnet wire 7.3 grams each
3 bridge rectifiers
1 cap

explanantion ...  a signal is apply to the first bridge rectifier .. it is then made dc .. that pulse is then connected to the input of the device ... out put of devices goes through a bridge to a cap

so as i apply power it should travel through the first bridge the 4 coils .. out to the cap .. ok
now where the first bridge hooks on add another the same way but after the first one .. so that when you cut your pulse .. the fly back has no choise but to exit where the second bridge is as the first one blocks it ..

see where this one goes ...  picture 15 ...  hummmmmmm
