Joule Thief

[gadgetmall]

Totoalas . Yes i know . I have a 12 volt system also with big panels and wind gen . I keep my light bill low with a 12 volt gridtie and a second 12 volt for inverters ans lighting etc. i agree there is a place for those experiments and also i have done them with a self charging bedini with a "piggy back coil" fun stuff for sure  .

I just like low to no power sources and i believe we just got one . If it every stops charging it must be running in the nano amp range with the dual diode and cap setup that is very dang close to what we are after here . Next test HV shocker! crossover mods.

Keep up the great work guys and lots of experiments left //

Thats great 
lot of options
been using a negative source battery connected to an open ditch canal in a slum area to save on wiring..........and only wire the positive like in automotive wiring for lighting    lol
Since the price of copper had risen    im planning to use a plastic hose filled with water in place of the battery ground    lol
your new set up is what im looking for  / maybe ill add a small solar from old calculators and you have your Eternity light 2        lol

@Gadgetmall... 1n80? I'm redrawing your schematic and .... er..... I can't find a diode with that part number, it comes up as a high voltage mosfet. Did you mean 1n60 or 1n34a, germanium diodes?

The only delay lines I've seen in these modern TVs are very strange slabs of glass with tiny wires bonded to them, I don't understand at all. They are very delicate but I think I didn't destroy this one, but I have no idea how to use it. Nothing I've done to it gives a reaction that I can tell. ADL-CN-336L is the part number, made by Ashai Glass Company in Japan.

What is the part number of the germanium transistors you have? My RM503 scope uses 4 in its preamp. I have a couple of 2n2635s left.... But no, thanks for your kind offer, I'd feel really badly knowing that the transistors cost so much. If you need this silly delay line I'll be happy to give it to you.


@gyulasun: No, in the LS ghostlight/crossover circuit I am using an E-core transformer-type thing from the TV, it has a primary of a smaller number of turns of thick wire like #24 and a lot of turns of very fine wire, #32 or finer. It's wrapped up in plastic tape so I really have no idea of the turns ratio except that there are a lot of the finer wire turns.

I have two of the coils in the resonance video, with the 1:1 windings and rectangular ferrite loops, they work well in basic JTs for LED lighting. I showed the smaller one in the "determining resonance" video. On my ProsKit inductance meter each coil measures about 21 milliHy. This meter is weird though... every time I measure a factory-marked inductor the meter agrees with the marking very closely if not exactly, in all its ranges. When I measure random or home made inductors.... it can be wildly off. I dunno.

My favorite TV coils are the ones with the magnets, as I used in the 4x NE2 JT.

  TinselKoala:
   To answer your questions... Yes, the white pvc is my 6 AA battery pack, it can be made in bigger sizes for C or D cells, and can be 6v or 12v or higher voltages if needed. The screw caps keep the cells tight, and has adjustable screws on the ends for connections. Works well, and costs me nothing to make it. It is also rechargeable from AC wall adapters, or solar panel sources. Works well for the 3.0 ringer circuit, but, I'll make a bigger 15 volt solar powered one for that project.
    If I move the big magnet that is under my transformer coil, it changes the sound and frequency of the ferrite rod's ringing sound. But not much else, at least that I can notice.
   I am not using the diode to the primary negative anymore, as it does discharge the batteries, and have moved it over like LS has it on the positive of the battery connection.  Now the10 led light flickers a bit, like Totoalas, or LS in their videos. The diode can be replaced with an led, which will sometimes light both ways,  strange, and even when just holding one end of it, while the other is connected to the secondary coil side, lights either way (polarity) around also.
  If I place a 47.000 microfarad capacitor as the input source, it will run a single led for about a minute and goes out. This is with an outside earth ground, connected to the same place as is in the LS diagram, but using no AC ground to my circuit, as I see no point in doing that.
  I still only see discharging of my AA batteries, but I know there is some magic to this elusive circuit, if you can find it. So, I'm still playing around with all this, not a done deal, by any means.

  12v solar powered circuits are what I'm after, as I'm trying to light my house, not just make more 1 volt joule thiefs. I already have a bunch of those. I do agree that it's best to use a single AA to perfect this circuit, until we get it right.  But, If there is no outside source of input coming into the device, there is NO way that it will make more juice than it's taking in.  The grid's ground, or neutral connection is not going to help, neither is the phone lines free 110 volts output.  But the phone line lit my house up when the power was out, and can do the same for you. So, keep it in mind... it could come in very handy, one of these days.
  Back to work on the cross over...

I have two glass germanium diodes . Opps. i know the one with  two lines is 1n60 . i use the one with one line so 1n34a ?

i have bunches of sets of germanium transistors . 100's of them .. from 2n123a up . i only have two if hep638's  ahh 2n1304 06 08's man i got lots of old can germaniums . there was a guy  selling them by lots of 180 at one time . I bought him out all 5 auctions.

TIA for a real schematic tk.

The delay lines are in old color tv's . It is a horizontal  coil wound with wire or there were glass ones also  on the Board and delays the color signal  . i remember them rater big and long though . kind of tapered on the ends. .  i have no idea what you got with a magnet . the only thing i remember after a two year college  coarse is the yoke has ring magnets on it to adjust the convergence Man it was way back in 1979- 1990 . i repairs 1000's of them till the boards became surfacemount and disposable  .. I had filing cabinets full of sam's for most of them. I have forgot most of it .
