Imhotep's Radiant Oscillator Video

[**~Imhotep~**]

Just wanted to say thanks for such a great effort on behalf of so many members here in creating and developing the radiant oscillator circuit.

I decided i would replicate the basic circuit using a 9 volt (12 amp) relay to begin with so i might follow the development of the circuit to its current state of progress.

I'm using a :
-Accel (model 8140C) 12 volt performance coil
- a 9 volt (12 amp) SPDT Relay
- Condenser from a Briggs and Stratton repair kit
- 100 ohm - 1k ohm pot and a 100 ohm resistor (relay)
- 1uf 100volt cap and 1 k ohm resistor on (relay)
- testing batteries are 12 volt 4.5ah
- 1n4007 diode (backend)
- two 3 level 12/20/26 watt (50/75/100 watt equivalent) coil florescent bulbs


Fired up on my first try. Was pleased. It began by drawing 3.5 to 4 amps. I was ready with 3 flat dime sized rare earth magnets stacked up to to tune the relay as suggested. It took me quite awhile to search out an efficient placement on the relay to achieve a reading of around .5 amps. (between 4.5 -6 volts) I also observed that the circuit would seem to draw less as the it ran quite naturally. Not exactly sure why that is. It was suggested that it was due to the warming of the relay. Could possibly be due to the conditioning of the bulbs as they run as well, i might suggest. At first i hooked up one bulb and had ran it for nearly an hour before i decided to hook the second bulb up in parallel with the first. Initially the two bulbs were very uneven in their luminosity. However, it was not more than an hour or so before they were much more evenly illuminated.

As far as charging on the secondary battery i have witnessed an increase from 11.50 to 11.89 volts in relatively short period (about twice as much as i've spent on the primary battery). I'm really impressed with the basic set up already. Just ran a short test run. Need to button down all my loose ends before really testing the charge rate.

Other than that i haven't made any other real major observations. The relay has been warm, however i'm not too concerned. It seems to be a moderate temperature at best. ( might need a ssg fan ! :P)

Plans for setting up a 555 timer to replace the relay as in other replications.
If anyone can see something i'm doing incorrectly please advise.

Thanks again to everyone here. Great community.
Heres a pic of my first set up.
Oh ya and thanks Lidmotor for waking me up to this thread!

Super capacitor Imhotep Radiant Oscillator

Its great to see more and more people building this and all the ideas coming together. Some of my feedback comments on Youtube indicate that some people are not quite understanding what it does. So I made a video showing it running on just capacitors to help demonstrate the charging aspect. Here it is. YouTube - Super Capacitor Imhotep Radiant Oscillator

Resonant charging circuit

Lidmotor, super video, very instructive ! It certainly helps spreading the message

Today my luxmeter arrived, cost approx. 40$

It is a nice tool, so individual tests can be compared for light efficiency.

Lidmotor, have you tried to experiment with chokes in series with your rheostat ?

That lowers the amperage more, if you tune the value.

On the Imhotep I have tried the primaries of some small mains transformers.

It is also helps to optimize the value of the "Briggs and Stratton" capacitor. I tried with some high voltage polypropylene caps to get it right, I have 0,5 uF. With 1uF it dropped again.

The "ignition coil" primary is 86 mH, the small transformer 84 mH. The frequency was approx 280 Hz, with the help from a finger it rose to 1kHz with more brightness. I have measured up to 700 lux, but not in efficiency mode.

I put the luxmeter sensor directly on the 23W, 125w equivalent bulb, and the tuning increased from 170 lux to 370 lux with my single simple coil.

I found a trick to make my results more reproducible. In the bottom of my relay there is a hole that fits a 2.5 mm screw. This way I can reduce the free play of the magnetic arm movement to raise the frequency, and adjust accurately too.

But with ordinary electric drive of the CFL's:

The 120cm 36W tube delivers 17000 lux when the sensor touches the surface of the tube.
The 23W bulb has 2/3 the wattage at a smaller area, so it measures 120000 lux in the same position as I measured on the modified bulb.

For the HV supply 3::110 transformer:
The open loop 120cm 36W tube delivers 9000 lux at the middle of one tube.
The closed loop of 6 120cm 36W tube delivers 20000 lux at the middle of one tube.
The closed loop of 4 120cm 36W tube delivers 22000 lux at the middle of one tube.

For closed loop the 3:48 was better, but I am not going to resolder for exchange.
The 3:110 has better open performance.

When doing the open loop measurements I used a finger as support when holding the sensor.
I can then see a redish glow inside the tube, and I feel heat but no electric shock, and my finger smells of ozone.

Closed loop did not show this effect.

Awesome demonstration Lidmotor. Obviously i have a lot of work to do.

Imhotep, i appreciate the comment on the site. :P I'm still very much a novice to electronics of any sort, however i can't seem to get enough of studying these types of circuits. I hope that by illustrating my projects on the web that i'm not misleading anyone. I'm doing my best, but i would be no where with out people like your self and Peter and so many others on here now that it is tough to mention any one with out missing some one. A great collaboration of minds here, i'm humbled to be a part of it.

On another note i have made an attempt to hook up a PWM in a bedini like setup in my radiant oscillator. I believe that i have it integrated in to the trigger position as Ipariah shows on youtube. The PWM adds 160ma to the load so i don't think that its ideal (has a built in fan). Just roughed it together and tweaked it down to as low amps as i can achieve with a very low illumination on the bulb. ~weak~ Fun to play with but not I'm not certain it would be the way to go. Need a simpler 555 timer type instead.

Heres a picture. Any suggestions are welcome, however i won't persist in flooding this thread with my project photos. :P

I tried running the oscillator yesterday using my little Bedini SSG as the trigger and it worked but the light was~ weak~ like yours so I went back to the relay with the little neo magnets. I finally crazy glued the bottom magnet onto the relay and used the top two with a steel washer to adjust the relay. Crude method but it works. I'm glad that you are sharing what you find out here. It all helps. Lidmotor

Hi thedude
i agree the bedini trigger pulls to much power also we need a coil collapse before the iguition coil to achieve better results. working on doing this witth the 555 but i will also build the relay setup too.
the selfdriving oscillation has more going for it with no outside input.

With the 555 and im trying to split the postive and negative of a second coil the pulse down the ignition its on the ipariah reedswitch video this one is a simple version to show the concept.
Have fun

Ps Anyone had a blub go orange run my 555 setup over night to test the charging.In the morning the light was very very low and had a orange glow.
Put in with some more blubs and there fine just that one, any idea folks?

[thedude]

need more time. :P

Thanks Lidmotor. You too Bodkins I appreciate your work on the 555 timer set up as well.

There is something about playing with a PWM that i found enjoyable. In playing with the gate and the pulse being sent to the coil i found that i could dial in efficiency and it would light multiple bulbs in a parallel (not in series for some reason) with near to same brightness as just one. I only had 3 helicoil to test at the time though. :P The setting that i had going in the photo was doing this. I doubt the PWM could handle the draw of 2 coils but i might give it a try before moving on to greener pastures.

Lidmotor have you observed any wear in the relays that you test? I had the thought that the relay i'm testing was becoming easier to tune for efficiency as it accumulated run time. Too early for me to tell, was wondering if you had made any observations. Had any burnt out? (sorry if i missed this topic some where else).

watched your vid lidmotor . great demo i will have shiva put with the growing collection on the website . well done

Some sucess with bedini circuit

I hooked up the ignition coil as the power coil in the bedini circuit and then set it into self oscillation mode. Normally the wheel goes into self oscilation mode while balanced between the magnetic poles on the wheel. Pretty bright and cheap and charging my secondary banks better than before with the wheel running! Current draw is only 190-200ma in the picture.
Also observing a radiant effect whereby i can remove a connection in the series of bulbs and one or more will keep running with only one lead hooked up.
WILD! I love this stuff.

Heres a video to show what i'm seeing on Modvid.com

Or on Youtube, which ever you prefer.




I'm going to hook up my probes and try to get some scope shots to show.

Thanks. Maybe this will help people realize that your invention is more than just another way to light a flourscent bulb. The charging aspect is very important and you and Peter did a great job with that. I'm still struggling with my relay to get it reliable and stable. Today I squeezed the whole oscillator into a plastic 1ft. square tupperware box. A very tight fit but it all went in. I'm getting it ready for use on my boat. Thanks again for doing this and making it easy enough for a novice to build.

Kinda falling behind the rest of u guys, since I can't seem to get my relay to stop welding it's self.

Hi Guys,
Carl I'm having the same problem. Every time I get it set at the perfect setting, I go away for awhile and the oscillator stops. Then I give the relay a tap and off she goes again. Good news is that the relay has not burned out and seems to run better and better. I have everything else in the system exactly where I want it. The brightness is good. The charging is good and the whole thing is enclosed in a box now. I found that if I run it off a small plug in the wall 12 volt power supply that it runs stable so I think that it maybe a voltage drift that is messing it up. Anybody else got any ideas?

Thedude,

Very cleaver running the ignition coil from the Bedini coil trigger! Can you give us the schematic of the circuit you show in the YouTube vid? I'm sure others would like to replicate this.....including me!

Keep up the great work!

I'm now using my SSG Bedini computer fan to run the lights. By connecting a wire from the collector of the transistor to the negative of the coils it provides brightest light and no relay noise.. I can then use the potentiometer on the SSG fan to control amp draw.

I'm just playing around with using the relay along with the fan to see if it will improve brightness more.. at the moment all it is doing is adding amp draw but no extra brightness.

Like thedude I can stop the fan and it continues to light up even brighter!

555 driver

howdy is anyone using a 555 driver circuit for the coil, im not getting as bright a light as the relays and would like to compare notes,any circuits for twin coils,double coils,cheers te
