Relay charger: 160V output from 12V input, but not useable ???

Hi guys,


I tried your Imhotep relay charger with no success using:

1 x 12V, 2Ah lead-acid fire panel battery for 'drive'
3 x same batteries parallel connected for 'charge'
1 x diode
Earth connection via power socket
12V car relay
No LED


Multimeter readings:

Drive battery = 12.5V
Charge bank of batteries = 10.9 V (residual voltage after depletion through a car headlamp bulb)
Charging terminals with charging batteries connected = 12V
Charging terminals with charging batteries disconnected = 160V


Observation:
The 160V above suggests that the relay is causing surges as desired, also apparent from the disturbed
multi-meter reading appearance. Strangely it is only present after the diode. Before diode is 12.5V
charging battery voltage, so diode appears to step voltage up for some reason.
Earth connection has no effect.
LED ommitted because I do not have one & it appears to only be for indication.
Tried substituting in a wire instead, but this gave the anticipated short-circuit.
Charging terminals lose their high voltage when the load batteries are connected.
Battery bank, when new & charged, lit the lamp for 1.5 hrs.
After discharge & re-charge attempt with this circuit for 2 hrs, bulb lit for only 5 mins,
which was likely just residual charge in discharge bank.
Tried substituting in various loads in place of charging bank: 12v car lamp, 110V drill & 230V house
bulb, but circuit had no effect on any of them.



Conclusion:
Perhaps LED does make a difference, or maybe I have overlooked something else ?



Your comment would be much appreciated.
Thanks.

Joule thief bedini

Hi Mate,

Howd your op go? Obviously you have the use of your fingers

Just wanted to share my view on a couple of points.

I feel that most joule thiefs are HF transformers, but not air core. Most utilize a core of some sort dont they?

And I thought the joule thief does use the collapse, just in a slightly different way. The collapse is present in any circuit that oscillates, the sharper the "off" the harder the collapse.

Regards

Yeah surgery seems to have worked. I've never hooked a jt up to a scope, but I assumed that because there's no recovery diode that the voltage spike would be shuttling energy around inside the circuit, not bringing it in from the outside...

Could be wrong.

Iquorate, Mike, all..
This video may interest all. He's eliminated the 2n2222. I had already commented on youtube, question if the osc is coming from the earth or the bemf (flyback) from his own circuit. I guess I'll take the long trip to get the real thing (2n2222).

The bedini and imhotep design works on high voltage from magnetic field collapse. The Joule thief is basically a high frequency air core transformer.

For recovering a battery I'd go with a bedini. Charging, Joule thief.

But I'd love to see someone merge the two types; a Joule thief with inductive collapse.

Inq,

Wiring is okay. I can hear buzzing in the coil with no light flash, and so something is fishy. I'm wanting to add the Tesla Switch to swap the batteries. I've not yet seen this attempted. There's a 5 to 30 minute 555 timer circuit here:
5 to 30 Minute Timer

Thanks,
Smikey

Smikey,
I don't know what schema are you trying to build. But try to put Avramenko plug at the HV output of ignition coil and connect CFL to it. I don't need to mention that you are dealing with HV so be careful.

Does your 2n2222 collector join to the collector of the 3055, and the 2n2222 emitter join the base of the 3055?

If it still doesn't work I'd try new transistors before trying a new ignition coil.

one of them may have blown up

[sirmikey1]

Mike, Inq, and all,
Many thanks for the heads up on exactly what's going on here. I've tried all of your suggestions and much more, and can't seem to make it ping pong. May be something in this house, and the only thing I haven't tried is another coil. I can't believe the hours that I've put into this. Tried like 30 different transistor sets/combos. Keep smoking up the house . I'll try another coil

Which one?

i have few questions to ask from you.... ...
using joule thief and the bedini pg 46 charge.........

the bedini charger uses capacitor, and scr to give high voltage spikes.......but the jtc

gives out jigh voltage spikes with a very very higher speed than the bedini one........
so i would ask that which one si better in camparison by using them to desulphate

battery????

does the bedini will desulphate a battery faster than the jtc???
and i mean the slayer big jtc is camparitively cheap to make and its components are easily

availabel in nearby shops......

so do you think i should go for making a big jtc with multiple coils or the bedini

charger......
i wanted a charger which occilates all by itself....the jetijs charger need to move a magnet

in its coils



kindly help me out ... really confused........
thanks

Self oscillate

Hi folks,
I've been following the imhotep thread off and on for a while now, and am curious to know why I can't get the aromaz 2n2222 audio npn transistor to oscillate. Lidmotor had the same/similar problem and added a pot & rheostat, and I'm wondering if someone could give me a few tips in this area. I didn't have a 5k pot, tried a 10k, no luck. I'm no electronic term techie here, just a very basic understanding of what does what.
I do get some voltage passed to the 2222 emitter when I touch the base, around 1 volt at the 2n2222 emitter and around 5 volts after Aromaz's darlington pair (5055) emitter. Add the 10K pot, and it's much higher, 12v on the Emitters. Help? What's the trick here?
Please and Thanks in Advance,
SirMikey...

It works because the base of the transistor rectifies ac em radiation into dc pulses;

See here for explanation YouTube - poor man's spectrum analyser theory of operation

Add an aerial or piece of aluminum foil to the base of the transistor and it will start working. A spark from a piezo lighter will start it up if it needs a kick.

Love and light

help bod...im a little out of my depth here....especially after seeing 430 VAC and 1200 VDC on the meter !

That's the spark causing (at least) voltage gain thru the high frequency discharge thru tiny capacitance and tiny Inductance LC tank that all sparks are..

The wierd part is the dc gain re the ac gain; with spark gap the dc increases much more.

What the?

Check your meter isn't being thrown out of whack by the RF+ coming from the spark. Do it by adding a capacitor to the bridge rectifier. Run it for x seconds without the spark. Then check voltage while ignition coil off. Discharge the cap. Then run for x seconds with spark in circuit and again check voltage in cap.

I'd be very interested to see if the spark gap is a loss or a gain mechanism.

Great work Rave, thanks for reporting your findings.

Love and light

sirmikey1,
when I was playing with Aromaz schema I was using 2n3904 transistors instead of 2n2222. I wound wire around ignition coil and one end connected to the base of 2n3904 other end of wire wasn't connected to anything. Hope it will help.

making jtc with multiple coils or the bedini solid state pg 46 charger

Imhotep,

Yes, that is the circuit that should be interesting to test. I recommend that the two ignition coils be identical for these tests, as you want the rise-times of the two HV impulses to reach the CFL at the same time.

As for possibly recovering power from the secondary to charge another batter, my guess would be that this will not work very well. The impedance mismatch from the HV to the battery would be considerable, so the efficient transference of energy between the two would be low.

A Special Congratulations to everyone who is experimenting in this thread and posting films on YouTube. This is exactly what Imhotep, Shiva and I had hoped would happen!!

ok, now even stranger

same circuit as my last post, with the addition of ...

coming from the HT lead....as well as going to the first CFL.....also going to 1 end of a 6 inch flourescent tube......which is inserted into the air-gap core of my coil...
also... the AC input of the rectifier only has one lead connnected to one lead of the coil...

giving 744 VDC after rectifier....also 246 VAC going INTO the AC side of the rectifier

Help !

whats going on !?!
