interesting here is tunning resonance-as showed in video. Question is how?- there is not any trimmer pot or capacitor. -as per drawing. So how he change frequency?

Turn count and/or capacitor value C3.

Well, I must say, I'm impressed!

"Objekt 013b"...  I've started making the PC board for it, and I have all the other parts on hand. Except for the C-cores...

Do you think a toroid would work instead?   ;)

Are the "330" capacitors 330 pF? I am assuming they are, from the small size. What is the Diode D1? Looks like  maybe a small Schottky like 1n5711?

Good Day TK

This looks very similar to the device that Delemort made last year sometime using the same MC34063 chip.
He used a pot type core, so maybe that could be substituted?  I guess the $100.00 question is what type of core material is it? ( assuming it's not an April fools joke)
Super simple topology looks like super critical tuning to me...............

The color of the diode almost looks like a *diac*, but that would be too high a voltage range for this design.

take care, peace

R1 is one ohm, according to the schematic.

A ceramic capacitor marked "330" is usually 33 pF, so that's what I used in my build. I could also try 330 pF if I can find any in my box of goodies.

I used a flyback transformer core and wound the same number of turns as indicated on the schematic, and I used blue LEDs because I'm all out of white ones. I used 1n5817 Schottky for D1.

It works just the same as what is shown in the video... except that it does not keep running when battery is disconnected. Awww.... what a surprise.

I am also getting two cycles of "ring" for each output pulse from the 34063 chip and I _think_ that the video is only showing one, so this probably  means I still need to "tune" something. But the lights dim slightly when I select the "on" position of the switch, just as shown in the video. I'll show waveforms later on. I'm surprised at the peak voltages I'm seeing, over 55 volt peaks on the primary side when 9V input is used.

hi Tinselkoala,

There is a small problem with 1n5817 rated 20volts if the peaks is hovering somewhere below 100volts.

Maybe a UF series diodes of around 100volts ...200volts rating would solve the problem of ou if your lucky on a Good Friday.

Let's hope it was not a Russian version of "DR Lirpa Sloof"

Try tuning by varying the gap ever so slightly with shims while observing scope.

330 pF would probably be the correct value for C1 and C2.

Try a little bit of biasing with a PM.

Heh... I think that Dr. Lirpa Sloof has been the mentor of these folks for quite some time...

Yes, I thought of that too. So I changed the diode to UF4001. The only change I can see so far is indicated by the circle on the scopeshot below.

Try tuning by varying the gap ever so slightly with shims while observing scope.
The above shots are done with no gap, clean faces in contact, core halves squeezed together with rubber band.

For the TestPoint 1 trace, as I increase the gap the voltage goes up, to a  maximum of about 90 volts in the first peak, at about 1.6 mm gap. I'm just putting shims in on the "round" side of the flyback core and letting the rubber band pull the halves together, so the "square" side is still in contact.
This happens without any observable change in brightness of the LEDs with S1 "on" but _reduces_ brightness when S2 is "off". There is very little change in frequency of either the main pulsation or the double-peaks.

I'll change the capacitors for the next tests.

Bringing a strong magnet into contact with the core, in combination with 1.6 mm spacer,  has a pretty strong effect on the double-peaks, turning them into a single peak. Max voltage (90 v) and main pulse frequency are about the same as without the magnet. The LEDs are visibly dimmer when I do this.

Still no tendency to keep on running when power is removed, though.   :'(

You're welcome.


Well. Going back to no spacer in the core:

Capacitors marked "330" are 33 pF. But just in case 330 pF is meant.... I did some experimentation with 330 pF. Changing C2 to 330 pF didn't have much effect except raised the peak voltage at Testpoint 1 a bit. Changing C1 to 330 pF made a big difference, slowing the main pulse down and other waveform effects. By playing with core spacing I was able to get a single peak within the main pulse, similar to what the video shows.

BUT... Fooling around in this mode I have managed to blow 6 LEDs and 2 MC34063 chips, and I don't have any more spare chips, so I changed back to 33 pF for both capacitors. The chips and LEDs seem to blow when switching S1 from "off" to "on" while power is applied, or just after running with switch "off", removing power and switching "on".

With 33 pF as C2 and C1: with S1 "off", applying 8.7 V power lights the LEDs well. Then when switching S1 "on" with power applied, the LEDs dim a bit. Removing power, they go out. If power is removed when S1 is "off", LEDs go out. Then switching S1 "on" makes the LEDs flash briefly and brightly once, as C3 discharges.

With 330 pF as C2 and C1, behaviour is similar except that when S1 is switched from "off" to "on" LEDs and chips tend to blow.

I'm going to try using a higher capacitance value for C3 tomorrow, if I can find some spare MC34063 chips at the dollar store. The LEDs I'm using are from a very cheapo "christmas light" string, I have a lot of them and they are really poor quality so I don't mind blowing them. Blowing the chip is a drag though.

I'm sure that the Eastern watchers are very amused by my efforts.  ???

On video you can see about 630khz resonant frequency.-(that could be harmonics)
Btw Your primary coil is not litz wire as in original video-don't know if is that any difference or no?

However here in this oscillator  is one frequency x .

Somewhere on 3v thred was user avalon post test with 2 frequencies and get "fero-resonance"

I try  -test- coil from dual tl494 experiment with 2 signal generators with test range 0-2Mhz-and nothing.
Best result (highes voltage) of mixing was nothing near avalon experiment.

Mc34063 50pcs ordered so will be possible to burn something :-))

wire is litz wire, capacitor 330пФ (330pf) p=pico.

You will get nothing untill you don't find ferro-resonance for ferrite.

Ferrites are like a women - every one need a "key"  :D

Hint: Take care about "winding directions" as i said in my previous posts. Flip ferrite halves. Do experiments don't wait "key in hands"

Hey eugene900 - Do i see newest upgraded Rigol DS1054Z or is it Mirage ??  ;D

Hi Enjoykin,
Ferrite cores in the image above can be found or purchased from? You can tell measurements Kohm / cm on a clean surface of the core. . . this is just a little comparison, the core that I'm there. . .


Thanks

@Enjoykin:

Are you absolutely sure about that?

It is definitely true that standard markings for ceramic capacitors use the last digit as the exponent.
So capacitors marked "330" are 33 pF.
That is, 33 x 100 = 33 pF
"331" means 330 pF, that is 33 x 101 = 330 pF
"332" is 3.3 nanoFarad, that is 33 x 102 = 3300 pf or 3.3 nF, etc.

Do you have any evidence for the "330 pF" value of those capacitors?

Yes, roughly. See the scopeshot from the video below. I make it about 615 kHz or so. Odd, isn't it? The scope is indicating a wrong value for the frequency displayed. (The video is a prime example of what I call "scope abuse", by the way.) This is the primary pulsation of the MC34063 chip, I think. A harmonic? Maybe...

My own build is pulsing at about 215 kHz with the 33 pF capacitors and the 220 uF electrolytic, using the same number of turns listed on the schematic. Odd, isn't it?

Ah, I didn't notice that he used Litz wire. I have some but it's a bit smaller than what is in the video.

Does it make a difference or no? Well, there are any number of things that could "make a difference" to make any replication not work as a self-runner. It is up to the person claiming to have a self-runner to show that there is some difference: Compare Litz wire and ordinary magnet wire, all other variables kept the same, and show some difference in performance if there is any. Since my build doesn't self-run, it's easy to wave your hands about and say "well, he didn't use Litz wire, he didn't use a mystery ferrite core, he did his build at night on Thursday and wasn't holding his mouth right, so no wonder it doesn't work."  All of which without any evidence from the original claimant that any of those things actually do make a difference.  There are literally thousands of "third variables" that can be blamed for our replications not self-running... thickness of PC board, latitude of location, atmospheric pressure, exact ferrite dimensions, composition, aging.... it is always something. Send a working self-running unit to me, and I will explore the problem space thoroughly and rule out possible third variable problems. Otherwise.... good luck.

I ordered 10 chips for about 3 dollars but they won't be here for another week or 10 days. Meanwhile I can get them for 1.00 each at the dollar store, inside a "usb phone charger cigarette lighter plug" thing.

I like your oscillator!
