Imhotep Oscillator Fan/Lite--Solid State Cap Pulser

[sirmikeydotcom]

It's going to kick everything up a bit. The important thing about this, is that Stanley Meyers fuel cell accomplishes with a half amp the same work that Joe's Cell requires 30amps to do. Duh! I hear bells ringing. A capacitor (hv pulse) can provide one hell of a HP punch to get a motor going. HV pulsing or cap dump is therefore capable of providing horsepower without amps, using HV instead? If so, then could this technology entend the life of an electric car battery or home generator battery?

I've been looking at the water sparkplug videos, and they are adding a HV 12KV diode from Microwave oven, connected between the coil positive and the coil HV output, which kicks the HV output spark up trememnously. What effect do you think this might have on your LB circuit? What effect on the back-emf pulsing? Would this help with efficency in any way? Here's a sample vid, watch timer for 2:30

I have been following the water spark plug project also. I have already bought some big diodes. I just have not had the time to try the experiment. I don't think that it will work well with the CFL.

[sirmikeydotcom]

Isn't the coil oscillator more practical, more kosher? Lid, everyone is watching you, mainly, and so try to be careful to prioritize things, and stick to the most practical circuitry. Each video you make is really a progress report or update on the circuit, so try to keep that in mind.

[Lidmotor]

Thanks sirmikeydotcom. You are right the primary purpose of this project (put forth by Imhotep and Dr.Peter Lindemann) was to develope a simple efficient light with energy recovery that anyone could make. If this thing gets so complicated that it has to be built by a big tech company, then there was no point in doing it. The LB (lunch box) version is porbably a good place to stop.---For me.

[sirmikeydotcom]

The fine-tuning will be interesting, and then hopefully to up the wattage (heavy duty version). Thanks Lidmotor, good job.

[calfellows59]

Your work on the project has been groundbreaking, priceless. You have kept things moving very quickly, have accomplished so much in very little time; and it's likely that none of this would have ever happened without you.

One question: Can you please explain why you can't pulse the car coil back EMF into the main battery, and what happens when you do? Would regulating the input, losing the spikes, allow you to do so? Thanks LM

[Lidmotor]

This what is called an open loop system and that is why it works. You can't put the energy back into the front directly. The way to do is to let the system run and then swap the batteries around after a period of time.

[calfellows59]

Why can't you put it back into the front? Does it foul the circuit or oscillation, or is it just that it's weak current trickles which aren't strong enough to be asborbed, get lost in the running circuit?

[Lidmotor]

I wish that you could that. It would be so much simpler. Unfortunately the system sees putting back energy into the front as a short circuit and just shuts down. Sparks, smoke, and melted wires. :(

[calfellows59]

Another 555 timer to swap the batteries along with cap pulser? Need first to look at the efficiency?

[Lidmotor]

Yes. There is a way to do it if you engineer a circuit that quickly disconnects the drive side while the charge side puts the energy back in. Efficiency is a big issue. Are you going to gain anything- bottom line- by doing it. Circuits eat energy for breakfast and don't leave a tip. lol

[Drevtoobe]

So you are still having fun and learning! I have to confess that I was fooling around with 555 timers and breadboards and stuff like that 29 years ago to make laser light show equipment for discos! My how the time flies! lol Triacs and silicon controlled rectifiers control all the lighting equipment for the disco dance floor! Keep on boogieing!

[Drevtoobe]

I am going to make some suggestions for your circuit. Ha! ha!, time to stir up the pot!!

I will start with a disclaimer, I am not building the thing and there is only so much insight that you can have watching a YouTube clip and looking at a schematic. With that being said....

On the top half of the schematic I would get rid of the whole trifilar circuit and both full wave bridge rectifiers. It way too much guts just to fire the transistor. Replace the whole shebang with a second 555 timer

[Drevtoobe]

I honestly don't see the reason for the opto-coupler and the SCR either. It looks to me like the high voltage to light up the CFL can't go anywhere else and is not a danger to the rest of the circuit.

Imagine this: A 555 timer drives the main transistor + bifilar coil (a.k.a. a step-up transformer) to light up the CFL.

A single diode (replacing the FWBR) off of the primary of the step-up transformer transfers the energy in the primary coil to your capacitors, which have a common ground...

[Drevtoobe]

... which have a common ground with the supply battery. Therefore, as the circuit runs, the voltage on the storage capacitors keeps on going up and up.

The charging batteries share a common ground with the supply battery and the storage capacitors. Again, this is somewhat unusual as compared to a typical Bedini circuit.

Between the storage caps and the charging batteries there is some sort of solid-state switch that is driven by the second 555 timer circuit.

[Drevtoobe]

Now I am going to throw some serious added value at you that is going to stir up the pot even more. The original 555 timer that times the charge dump for the caps is running as a "dumb oscillator", a.k.a. "bistable multivibrator." You want to run the 555 timer as a "monostable multivibrator". In plain English that means that you trigger the 555 timer and it generates a single pulse, and you choose the R and C components to set the length of the single pulse. Now for some secret sauce....

[Drevtoobe]

The secret sauce is to trigger the 555 monostable multivibrator from the voltage on the storage capacitors themselves!! You make a resistor divider network with some fairly high value resistors (so as to mot loose too much energy) and connect that to the 'trigger' input of the 555 timers. YES, that's how a 555 timer works, it is simply waiting for the voltage on the 'trigger' input to reach the 'trigger threshold'.

Okay, so now you have a 555 timer chip set up to automatically dump charge...

[Drevtoobe]

... to automatically dump charge from the storage caps to the charging batteries when the voltage on the storage caps reaches a certain voltage. You can control that voltage easy as pie by changing the values in the resistor divider network.

The only thing that I am not certain about is the silicon switch between the storage caps and the charging batteries. It could be a PNP transistor, or an FET, I'm not sure.

I know that text-only is very limited, but try this "text block diagram"...

[sirmikeydotcom]

Are you using bedini fan as oscillator in this video? Was your own oscillator causing problems? Just that oscillator also needs enginnering if that's the case.

[Lidmotor]

To test out the cap pulser, I'm using the fan oscillator circuit with a single ignition coil attached to drive the CFL. The LB (lunch box) unit is all buttoned up and working so I did not want disturb it. I may make the fan as a pulg in to the LB. The pulse charger circuit will work on either one.
