Imhotep's Radiant Oscillator Video

[hh1341]

Guys,

If the SS frequency is very high, would that result in the ignition coils' HV being reduced ? (coil can't keep up)

Any idea what an optimal freq would be?

Also what would be good test points, to check this out on a scope?

Hey fellas. Take a look at the schematic i drew. Im trying to charge the same battery with the radiant energy between pulses and its working. The only problem is that the wires going to the primary of coil are getting warm.

It might be just taking too many amps out but let me know what could be the cause of this heat. Anything else that you see here that could be improved let me know as well.

hi do you need the relay .to drive coil,if you can pulse coil with 555 driver, the negitive runnung thru cfl back to battery ,will charge battery with no diodes and no heat .lets know how you get on, cheers

hi Carl
dont know what freq are best but the scope can go one end before the coil
and one end after the coil if you have two battery setup put one end on the -charge battery and the + of the primary Battery and the other atfer the coil.

Ren,Lidmo ,imhotep
thank everyone for the feedback will try and improve my video quailty in the future.
started playing with chokes the scope shows bigger leading edge spikes.
any ideas?

Coil Overload

Coil overload............

The reason I bring this up, is........in an 8 cyl ITCE at 5000 rpm, the coil fires 333 times a second.

In my SS IROL replication, the coil fires 3000 times a second. I don't think the coil can keep up with this rate. I very much suspect the coil is not giving out it's 40,000 volt, rated voltage.

What say you all?

[ren]

maybe not Carl, its enough to work with though.

I guess this thread is a little quieter because people are busy in the shed

I changed my setup to have two Ign coils and got better results again I have it setup now like others have shown previously, where the lamp is between the two central plugs. This way it doesnt flow straight to ground. I start the charger and it draws 300ma. When the light is put on after warming up (10-20 sec) the draw drops to 270-80 ma. Charging isnt as pronounced, but still does charge. The way I had it arranged before with it flowing to ground it would start on 300ma and jump to 400 or so when the light was on.

Pic is 12v. 20w globe. Fan I adjusted too (Thanks JKoorn ) and it goes HARD now.

Ren I wish that I had a shed!! All I have is a dinning table and a kitchen countertop. Anyway I have been working on the cap pulser and have been very frustrated. I tried to make a simple 555 timer circuit yesterday and failed terribly. I didn't have the right parts, big hands ,bad eyes, wrong circuit board, a total disaster. So today I just threw together a crude pulser using a little motor thing that I got at a surplus store. It worked well enough to catch the principle. Sounds like everybody is busy. Here is a video of my very simple cap pulser that I made today.

Thankx Ren and Lid, et all. At the rate you guys are going your gonna solve the energy crisis by the end of the year

[ren]

lol Ash.

Lidmotor, good work, you thought outside the square and figured out a way to pulse the cap. It can be frustrating trying to put together a small 555 circuit, but if you take your time and get the proper parts you may have more luck.

Look for a prototype solder board made specifically for IC's. The one I got is great. Room for 18 pins and it spreads them all out to make attaching simple. You can see it on my pics. The cap pulser isnt something you can just build and it is gaurenteed to rock straight out of the box. Im still finding out new tricks.

Whats the capacitance of your cap Lidmotor? And also, have you tried removing the caps off the Ign coils? I found that they smoothed out power to the light, but dramatically took away the charging ability.

Preliminary operational emergency fan/light combo.

Its a 6 inch by 8 inch by 3 inch case. This first version can be ran off the fan electronics and relay. Pulser circuits to follow. More work to do.







The fan folds in for storage. On low light level it draws 400ma @ 12 volts. (SS) Fan and light running with 12 volt charge. High light level 700ma @ 12 volts with 12 volt charge. (Relay).

Ahhh the king returns!

Nice compact unit!

What size is the globe?

[waterhouse24]

Great compact unit Imhotep!!

The only thing I have tried new is using 2 small 9v batteries in series to make a bright light with less bulky equipment..

Miniaturisation is my next mission

Interpretation Of Ren's setup-[ 12-volt system ]

This is my interpretation of Ren's setup using 12-volt sytem. I uploaded this schematic as a guide to beginners in electronics like me. Anyone can correct errors in this diagram. Only one coil is used here.

Please proceed to post # 592. Thanks.

If we are getting better results by raising the drive voltage (24/36v) then getting more out of the coil in the first place would mean we could continue to use 12 volts.

I would build a coil, if I had some specs. Or maybe try a voltage doubler.

thanks agongon i love the little picture it makes a bid different for me personaly.
one question what the duty cycle on the 555 and pulse rate?

Great work Sir

Thanks Agongon,

Like Bodkins, this makes a big difference for me to be able to see what is happening with that sort of a circuit diagram.

Imhotep,
Great build!! Now that this is really taking on a usable look to it, more people are going to want to build it. I like the way you did yours with the fold away fan. With that CFL bulb sticking up in the air with those two "coil towers", it takes on a kind of Dr. Frankenstein's lab look. Put the bulb in flash mode and it would be great for Holloween. lol

Ren,

The cap I'm using is a 1000uf 50 Volt. I tried several like you and Bodkins advised and this one just seemed to be the one that worked the best with my simple pulser. As far as the caps on the coil are concerned, I tried taking the cap off on the Bedini Fan unit and it didn't work. It might be just my particular circuit. Carl has been playing around with it also. As far as building the 555 pulser circuit, thanks for the tips. I didn't have the right parts.

Waterhouse,

Miniaturization is where I'm at also as soon as I get this cap pulser figured out. I'm going to try a motocycle ignition coil when I can find one to cut down on the size and weight of the unit. I really like the Lithium batteries that I'm using now. Way to expensive though unless you can get them like I did on sale some where. The back end charging aspect of them is still to be determined however. I think Bedini says lead acid only if you really want his design to work right.

Cheers,
