Imhotep's Radiant Oscillator Video

[Jetijs]

Mart,
I already tried a high power solid state relay. I used my function generator to pulse it. It did not work well, I could not get more than about 15Hz, because after that the light just goes off. I suppose that this is because the relay has long rise/fall times.

i looked at that coil wow those are the cadillac of coils

Yeah.......60,000 volts......it's starting to get scary.

BTW....how can we measure the HV on these things without blowing up our meters?

you can get a high voltage probe to measure the voltage ,they sell add ons to expensive fluke meters ,or you can get a stand alone probe some are inexpensive on e bay or on the net . it is similar to taking the hv reading off a tube tv flyback transformer . there is also simple plans on the net to build a hv probe . but remember this output can arc 2 or 3 inches ,i have been hit twice now and survived .the other day when making the 2nd movie i just got near the exposed clip lead for the return ground on the dual coil setup and it jumped on my hand .always use one hand only and don't change any thing while it is running NEVER . and if you build a probe it has to be long 12 inches -24 inches i have to remind shiva to not pickup things near the tubes ,she almost grabbed the 48 inch tube that was next to the running one but i stopped her ,so if you have an assistant caution them also of the dangers.

I have a solid state relay, any ideas of how I would wire that in? I sure would like it quiter

i know i ran the proto for 72 hours trying to run the batteries down(which i gave up on trying not to mention i wanted to swap batteries but by the time 72 hours had passed Peters min run time was surpassed so i replicated another one to test if it was an annomily or a solid concept) and the relay was a quiet one but it was still loud .its easy to withstand the dishwasher or a drill or the washing machine but we are not used to our lights making noise . but i chose a relay for the interaction of the 3 coils . as far as a solid state device you are trying to switch the 12 volts on and off thru the primary .it is that simple .

I wonder could we use something like this to check the voltage on the HV end?

[hh1341]

But remember this output can arc 2 or 3 inches ,i have been hit twice now and survived

I think Tesla kept his other hand in his back pocket.

There are special rubber gloves that will handle hi voltage, as well.

be careful and if they are internally shunted they should be ok . i myself have only used commercial units that had long probes to stay away from the source of the hv .unless you are familiar with using these meters i would set them a foot or two away from yourself and use long probes ,real long






notice the long probe

One wire solid state HV CFL experiments

Jetijs,

I just saw your video, great. You certainly live up to your footer writing
I also saw Imhoteps new video with the extra CFL. Thanks to all, this is amazing and inspiring.

Although I at the moment ought to do ordinary work all my time awake, I can't help doing some experiments also.

The first picture below shows the high tension cord entering the picture from the right and connects to one filament wire. It is able to light the CFL with the other end unconnected.

On the next picture a test wire is connected to the other end of the CFL, the test wire does not touch the two other CFL's, a non modified CFL and the worn out 30W CFL tube seen on the picture.

The brightness of the modified CFL increases a little but not much when the crocodile test wire is connected to the other end of the modified CFL.

The third picture is a close-up.

The fourth picture I added two new and longer CFL's

The last picture I could not get enought space to view the whole length of the tubes, so you have to take my word for it.

I name the tubes right to left #1..#4
Tube 1, 2 and 3 is series connected, ie. HV cord to one side of #1, other side of #1 to bottom of #2, Top of #2 to top of #3. The bottom of #3 is unconnected.

I have the same tubes as the ceiling lights with high quality reflectors for energy saving reasons. Tube #2 closest to my small modified CFL has a brightness like the one of the same type in the ceiling, the long tube at the end of the series connection is about half that brightness. Note the hard shadow to the right despite the good illumination from the ceiling light..

Strangely my modified small CFL (#1) is now dimmed significantly while the next CFL (#2) in the middle of the series chain is incredibly bright.

The long tubes #2 and #3 are a high efficiency type marked 18W, the older and shorter worn out tube is marked 30W.

#4, the unmodified CFL same type as #1 (23W) still emit some dim light although it is 4cm away from the test wire between #1 and #2. It can not be seen on the picture because of strong light from #2.

The HV supply I made about 5 years ago for a specific purpose. It is strange that it can do this. At that time the only thing I knew about Tesla was the measure unit for magnetic flux.

excellent work !! Peter Lindemann understands this process much more than i do but i also was getting stange effects with glowing effects being induced in nearby bulbs .pretty cool experiments to do and learn from keep up the experimenting !!

Now two bright CFL's

I just added the worn out 30W CFL named #5 to the end of the series connection (to bottom of #3).

Now #2 and #3 is very bright while #1 and #5 ( the end of the series chain ) is dimm with #5 more bright than #1.

I also tried to put the #3 to #5 test wire in between the tube "windings" of #4, then #4 is nearly the same brightness as #5. And #3 now has a bluish color at both ends.

Sadly I have to say there is interference with my internet connection. Lately I have been subject to a man in the middle attack on my server, same day as the recent DNS internet error was published. I have several times been excluded from security updates. Hopefully this post goes through after I just lost my connection and had to reset my router. I'm not used to unstable internet, it is the first time I saw this router message.

Before joining a yahoo group (maybe an coincidence ) my previous for years rock solid linux, is not so solid anymore

Thank you for your kind words. You led me in that direction. I hope Peter has a little spare time to help us understanding this.

If it is not some kind of standing waves, I missed the train at the moment.

Now 6 CFL's in series, 4 bright, also series-> parallel->series test

4 bright CFL's, 1 dimm at each end. The second last ( farthest from the HV cord ) is slightly less bright than the 3 preceeding.

so

HV->dim->BRIGHT->BRIGHT->BRIGHT->bright->dim-> no connection

and

HV-->dim->|-dim---|
.................. |-dim---|
...................|-BRT--|->BRIGHT->dim-> no connection

Weird for this parallel series connection. is series they were equal brightness, in parallel two dim and one BRIGHT, maybe its just because the BRIGHT is not the same type as the dims. But why were they then equal in series. probably not the same gas density

Editorial: The periods are "white space" necessary for indentation.

Eric,

Would you please show us a photograph of the power supply that is creating these effects, as well as the schematic, and give us some idea of how much energy is being expended to light these lights?

Thanks,

Peter

Nice and very long HV probe, whats the voltage spec ?

I myself have an old 15 kV probe and a Tektronix 40KV probe. But until now I have not dared measuring my HV tension. I fear for my expensive probe.

Also please observe the derating of max allowed voltage, when measuring high frequencies with the HV probe.

The experiments started as follows:
First I tried with the high tension cord alone to one filament wire at one end of the modified tube, and no wires to the other end of the tube. The CFL was lit about the same as when connected to Imhoteps circuit, but with my home made coil instead of the car ignition coil.

Then I connected the HV supply ground wire to the other end of the CFL.

I hit the pushbutton very briefly to get a very short burst. The CFL bulb made a distinct sharp ping/bang like a flashlight, and the light also seemed like a photo flashlight in intensity.

Thats also why I tried the serial connection, maybe the parallel connected bulb would end up exploding.

My HV supply is aggressive. Arching to ground with normal wires just melts the ends of the wires.

Arching with Wolfram welding electrodes burns them after 2-3 seconds radiating UV light like a TIG welder, same intensity. Protect you eyes, the alternative is painful I can tell. even from relatively short time exposure.

My HV power supply was built for both HV and power. It is no watts sawer, but it has the tension to demonstrate some effects.

The question is: Can one of us succeed making a functional solid state supply without sacrificing the efficiency. From my 3 week build and optimizing period for the HV supply, the build up of the flyback trafo were the most difficult part.

And yes, take care.

16 years old I toyed with my homebuilt strong discharge ignition. A 2-3 cm spark went out of the insulation of the high tension cable and into my finger, through my body and clothes and through the insulation of a mains wire to ground. My heart went galopping missing some regularity, I just had to lie down. After half an hour I felt better. That was close.

Peter has did alot of experimenting on his own, and I am sure he has not shared alot of it with me. I will let him comment on his experiments with solid state. Myself I had examined their circuit carefully (cfl) and it appears what they are doing is ping ponging it through two fets's or two transistors coming from a torroid for very high frequency but i am sure it comply's with not emitting interference with radio frequencies that are utilized. I really dont know what frequency they are running at. But I do know they are hitting it on both ends continuously. Not what we are doing. I have seen various circuits that will do it from 12 volts, but they appear to draw more amps, the proper amps using ohms law. One circuit i saw was drawing about 5amps. But unfortunately drawing 5 amps off a 12 volt battery would run it down pretty quick and i dont think you can get any recovery off the torroids. Im not really sure I have tried it.

I thought very carefully before choosing this path, felt the light output was good, and with the low current draw and energy recovery it was a good alternative in certain applications. Other people in the forum have already greatly improved on the design and I like what i have seen so far.

I do relive you can go totally solid state but im not so sure on energy recovery or matching or beating the current draw with comparable light output. That would have to be worked out. Good luck.
