Well, it's hard to figure out what's going on from that photo-loop, but one of your scopeshots looks just like what

it's a video... click on it.

Well... I just received my new batch of 10 chips from China. And I can confirm that there are some differences in behaviour when compared to the chip I used for the video demonstration-- even though they all claim to be from the same manufacturer, ON Semiconductor.

The old chip is marked:

34063AP1
        XAA
and the third line has a shiny black concave dot marking Pin 1, the ON-in-a-circle logo, and digits 0244

The new chips are marked:
34063AP1
NCCKXNS
and the third line has no black dot, has the ON-in-circle logo (but looks kind of funny) and digits 1236

Both types have the usual edge-notch on the 1-8 pin side. The new ones are much easier to read, the markings are higher contrast.

The new type seems more sensitive to low voltage operation. Sometimes it makes a double-peak waveform at TP 1. Overall so far, I think the new ones work "better", for certain values of "better". At least they light the LEDs at lower input voltages.

@TK
Hi,I got a stable waveform,but the frequency is about  212Khz. I can't increase it to 640Khz . Can you give some suggestion?
Now my parameters are:

C1--33pF
C2--500pF
Primary coil--(20  0.1mm enamelled wire roll up to a Litz wire) * 28
Secondary coil--(0.6mm enamelled wire) * 66
D1--1N4148
LED--White light and diameter is 5mm

I also used a PCB.My waveform as follow:
Oh, my oscilloscope probe is 100:1 .

Best Regards

On the video i shared i got the Feq twice that, 460 Khz but I  had to use a 10 pf i got my chip a good while ago an ST CHN 063A, I did notice Tinselcoala's litz wire is very fine wire, it might be an idea to get an old relay coil and put a pair of nails in a 1o ft piece of wood one at either end and go up and down till the thickness is about 1 to 1.5 mm thick and use that as the litz, then re try keeping the C on the PCB as low as possible, good luck. mine still doesn't work! I haven’t had the time to do the mods yet !

I didn't use the C1, and the  highest frequency I can get was about 330Khz . I can't understand why Lari Man can get 640Khz.  If the C1 in my system is 33pF, I just can get 212Khz.  @TK, How much is your frequency?

Depending on the state of the 9v battery my frequency at TestPoint 1 can vary from 350 to nearly 500  kHz.

OK.Thank you ,TK. Your suggestions are always important and precious.  You mean the frequency is depended just on the primary, secondary coils and the C2? Is there some obvious phenomenons in your system when it really works? Just the stable single pulses at the testpoint1?  And whether your system always works when the frequency varies between 350khz to 500khz? I'm sorry for so many questions,but I think they are important for fresh man like me :)

Thanks again for your important work and kind guidance.

best regards

Hey  TK
Congratulatios on new scope ;D
do you manage to upgrade scope by program?
And change cooling fan? - how is result?

I'm sorry, but everything I know about this circuit is from data gathered while it is being powered by the 9V batteries (fresh or mostly discharged) or an external  power supply. As far as I can tell, a careful balance needs to be formed by turn count and capacitors, if you want to get to the frequency and wave-shape that are shown in the Lari-Man video.  Also, different MC34063 chips from different lots or different manufacturers seem to have different performance in this circuit. I don't believe that the device shown in the Lari-Man video is truly self-sustaining. Mine certainly isn't.

Thank you! It would never have happened without Chet (ramset) doing the legwork and gathering the donations from all the people who contributed, so I thank them all profusely.

Yes, I was able to upgrade the scope to 100 MHz and unlock the other options by using the keygen program as described in the EEVblog forum. But I removed (uninstalled) the upgrade and am now running completely "stock" at 50 MHz bandwidth with no upgrades. I will reinstall the unlocking key at some point... soon.

The fan is not nearly as noisy as I was led to believe. I have not installed the silent fan I ordered. I can't hear the scope's fan over all the other fans, air conditioner, etc running in my lab most of the time. The scope's fan does make a slight running noise but it's not bad at all.

Sometimes, a noisy fan is a good thing.  You can be alerted when it stops.  A few computers ago, I had a very noisy fan...used it for years...and one day...it occurred to me that the fan was suddenly quiet.  I shut down the computer and the fan was seized.  I replaced it and was somewhat dismayed that I could not hear the new fan, ha ha.  I was overclocking that computer a bit (to 4 gHz) so with no fan, it might have had a melt down.

Any instruction in winding the core? Perhaps, someone could help me with some links.

Hi @ all,
pursuing this project anyone further?
I want to build this shematic in the afternoon.
Than i'll post my results.

here are my measurements.
I build it exactly as shematic, only the core is from an old monitor.
For the first measurements looking at the picture.
Then i'll have changed the diode from 1n4007 to a schottky BYV 10-40.
There ist no different between them if i look on the grafics.
I've also changed the capacitor from 220µF to 100 an 1000µF.
There are only very small changes at the voltage.
How can you get more than 400 kHz? The IC operating at max. 100 kHz (datasheet)
I've expanded the shematic at one more TP. This measurepoint is at minus at the schottky diode.
Here is a verygood DC voltage from 17 volts with a very small ripple.
My total current is round about 100 mA. The LED's are very brightly.
