Wow....   Here's another one I like.  I just hooked the bulb in series with the battery and the secondary (higher winds) of the transformer.  Primary not hooked up to anything.  The bulb lights but is dim.  Then I short out the primary and it gets brighter.  But here's the Wow part .... take the short off the primary and it stays bright - actually it gets just a little bit brighter when I remove the short - and as I mention below is actually drawing less current while brighter.   Cool! 

Also checked the current on this setup.  When I short the primary the current draw on the battery is 16ma but when I take off the short it's 11 ma with NO change in brightness at all.   OOPs I was wrong after taking a closer look again it actually gets BRIGHTER !! when I remove the short and is using LESS current !!!     This part will be just the opposite depending on battery polarity.  If your bulb gets dimmer doing this reverse the battery polarity.

That's a neat trick.  Works well for me too.  I have noticed that sometimes the Hz will vary.  Sometimes I'll hook up and the AC off the other side will be twice as high.  I think at higher frequency the spikes go higher.  I have been experimenting to try and get the Hz up.  Any ideas?  I can almost light a standard dimmable LED off the isolated transformer winding.  I think if the windings were 20:1 instead of 10:1 I could get it lit.  Why?  Why not?

Just to share,

Here picture of my homemade LED used in the above video. I think it is not a dimmable one.

Cheers

Djoko, very impressive video.  Did you make that little LED driver?  Is it a transformer and a capacitor?  Do you think there is any advantage to lighting LEDs this way as opposed to just running off mains grid power?

A few more interesting results.  I tried with a couple other transformers and got no light in any configuration.  One was a toroidal power transformer.  Then tried with a NST Franceformer brand - it is 12 kilovolt - so 100:1 ratio.    It wouldn't work with power across the secondary in series with the bulb so I tried across the primary and it lit up.  with nothing attached to the secondary.  I read 538 volts across the secondary at 178 Hz.   Touching just one wire of the secondary got a biting zap to my finger but I had the transformer sitting on my legs on top of heavy pants.  Apparently that was enough to make a circuit - not painful but enough to know you are feeling a slightly uncomfortable voltage.   So be careful with this depending on what transformer and battery you are using I imagine with moist hands you could be getting close to a dangerous voltage.   Shorting the secondary with that transformer made the light brighter and was probably the brightest I saw in these setups.  I measured current across the secondary after getting that little zap.  It was about 0.59 microamps - list than 1 microamp.  Not much but it bit a little  ;)

Lynx, thank for the kind word. No I don't make it. This driver rated for 65 VAC ~ 265 VAC input. I got it from O/L store here in Indonesia, including the HPL LED Chip. For the emergency only. See, on 220 V x 0.018 mA =  3.96 W and on 36 VDC x 0.035 mA = 1.26 Watt. Actualy, I try your set-up (with various xformer) and it works, the I try other set-up/my set-up with out xformer.

Some more fun ...  I decided that even thought the secondary on the NST was seeing only about 1/2 microamp I might light a bare CFL on it (just the FL bulb part of a CFL without any circuitry).  It works with that 538 volts it lit but fairly dim - but still it was steady with only 0.59 microamps and the LED bulb was essentially the same brightness as a short on the secondary - probably 40 to 50 % of full 120 VAC brightness.   It didn't want to light a CFL with the circuitry though - but when hooked into the circuit the LED still lit up like a short on the secondary.

Great experimenting and information.  I tried torroids with no luck.  Only my largest aircores will work.  And yet a tiny audio transformer works well.

Please try something for me if you would.  I can almost light a 120 v LED bulb off the isolated winding kicking its pulses out.  It would flash and then fade.  There is very little amperage as you say.  But with high frequency and high voltage off your 100:1 transformer, perhaps.  And if you can light a bulb how does it affect the overall map draw?
Also try rectifying the extra AC output and use a high voltage cap across + and -.  In that way I could light another LED bulb.

Here's something very interesting.  (Prof Jones will like this) I had tried a tiny inductor (smaller than a penny) out of a gutted CFL circuit.  Its the two lead, wound, blue taped inductor.  Didn't work before.  Then I had wound seven turns of 26 awg magnet wire for the crossover circuit.  Anyway, it was laying there, so I tried it with 18 volts.  I had to clip the lead on to the small PC mount.  Didn't light at first, then instant on and Heat!  Not the temperature kind.  Radiant heat that penetrates at around 1/2"-3/4" surrounding the transformer.  The bulb draws 95 ma off this little transformer.  Shorting the primary, the draw is 80ma.  685 hz.
The seven turns works as well, 91 ma with the secondary open.  82 ma with secondary shorted, then no difference, 82 ma.

Also try rectifying the extra AC output and use a high voltage cap across + and -.  In that way I could light another LED bulb.

Spent much of the evening playing with this circuit (other room from computer) but done for the night now.   I did rectify the 538 volts coming off the HV side and tried feeding it back to the battery.  I tried an Avramenko setup also which was able to rapidly charge a 400 volt cap in about 10 to 15 seconds.   Tried all kinds of things but was afraid to put my one other LED light bulb across that output as it was around 398 volts DC.   And that particular LED bulb would not work in the circuit at all hooked up like I had the good one.   I had grounds hooked up, antenna's and so on.  Off that 12 volt Nicad pack which is probably a bit smaller than the size of a baseball I was at the point where it would take 15 minutes or so to drop .01 volts.   I also tried a fence charger transformer (I assume a fairly high ratio) which worked well only in series with the primary but had a fairly large current draw and was dropping the battery voltage fast.    I may try more tomorrow but things are looking fairly busy the next couple weeks.   Fun circuit and will try more as time allows.  Thanks Lynxsteam for letting us in on this one!

Forgot to mention one other odd thing I tried.  A few days ago I wound a nice 4" ferrite toroid with some very fine Litz wire in a Caduceus style.  So it has just two ends.  I hooked those in series with the battery and LED bulb and it lit up bright.  But it was pulling the battery down fairly quick.

Since all these circuits we work on are somewhat related to Joule Thiefs in one way or another, I wonder if using LS' and Gadget's idea of diodes across the primary/secondary would be interesting.  My guess is that it clips the time the transformer and transistor can conduct DC, and yet gives off the high voltage spike.

I would also guess most of the JT circuitry is already in this GE 3A15 LED bulb.  So by adding a transformer, diodes, capacitor and power source we may come close to the crossover.  I have run these bulbs off capacitor only, but not for as long as what LS is doing.  But I don't have super caps either.

@Lynxstream,
 
                  I broke a damaged 120 volt LED open to look inside. Your right, all the same componants we use in our JT'S, tiny transformer, rectifier, capacitors diodes and resistors!

Monster Transformer Results
« Reply #70 on: December 11, 2012, 09:51:42 PM »
@all:
You guys are way ahead of me, but thought this worth mentioning.  I salvaged a monster laminated steel transformer a while back from a UPS.  This thing is slightly smaller than a bowling ball.  I connected the circuit as shown in Lynxsteam’s drawing in post #47.  Not knowing which the center tap was since secondary has black, white, and blue wires ~ connecting one way gives 20 to 25mA at 12v.  Connecting to the other line it uses 45 to 50mA at 12v.  Light quality at higher current draw is obviously better.  When adding a second bulb, the current draw is doubled.  No sacrifice in light quality.  Even at the higher draw the bulbs are not as bright as 120v mains light, but quite nice nevertheless.  I will be trying some other hookup configurations next.

    My cross over circuit is still lighting the single led bulb that is the indicator light. It's been over 12 days, now. I think that this may be perpetual, but, there is just not that much useable light. Unless you disconnect it, and let the cap charge up the D cell battery up. Then it goes up to original 1.1 volts, and led is bright, for a while.
  No luck yet with the Joule Inverter off of the different transformers, running direct.
I think that my best luck will come from solar panels dirent to 12v bulbs. No losses, and bright light.

With lynx set up
12 v dc input to a 30 w 220 to 12 v xfr   690 mA  on a load of 7 meters led strip 12v  very bright
my jr 1 will dimly lit the strip at 200 mA
Direct connection of strip to battery     890 mA  the brightest ....
Some 220 v led lamps does not switch on   with this xfr

Look at Stefan's bulb transformer battery circuit below. The circuit in the base of Lynxstream's A.C. LED bulbs must duplicate the function of Stefan's relay. There's a strong chance the LED bulb circuit is generating electricity in the transformer secondary during the demagnetization phase of the charge cycle, just like Stefan's relay does in his shock charging system!
