Has anyone seen Lasersabers new motor runs on 1000uf cap

Hey Gyula

Yes I think that K is a tolerance value.  I looked these up last year some time as I was determining what caps I wanted to pull from PC power supplies.

I thought of a zener also, but he said germanium.

Laser doesnt seem to be one to pull the wool over our eyes, so I believe what he is saying. But its what he is not saying and showing that bothers me at the moment. Its the spoon feeding of info that has a familiar smell to it if you know what I mean. If I were to show something of this caliber, I would prepare all things and present it all at once.  The biggest reason would be to make sure it does get out there. The spoon feeding is a bad move in my honest opinion. Showing the vids, such as this, im sure that we(tinkerers, inventors, people on the ou quest) are not the only ones watching and knowing the difference between a simple pulse motor and what is being shown here. Im just anticipating that there wont be a complete reveal because he might be stopped from doing so. I pray not, for him and his family first off.  But there seems to be a pattern with spoon fed projects. Then when they back out of a complete reveal, some will just go for it and build, and as history shows, nobody ever gets it working. I guess we will see.

Are you quite sure about your caps? Not reading nanoFarads instead of microFarads? The web reference I gave says the K means what I said, and even gives the example of "10K" being 0.01 microFarad.
Can you post a photo of your caps?
As I said, the physical size of the poly film cap in the video seems too small for it to be 10 uF/100V.

Here are the dimensions of a typical 50 V 10 uF poly film cap. The 100 V one, if you can find one, will be even larger.
Length: 1.69 in, Width: 0.53 in, Height: 0.77 in

Searching google for "capacitor 10K 100" I get this link, which shows a 10K 100 capacitor: 10 nF, 0.01 uF. (not axial leads but the marking is the point).

So I'm not quite ready to redo my calculations yet.

On the issue of the series diode: I can't tell right off the bat about the drive circuitry. All I can say is that the amount of drive that he gets from the capacitor seems a bit large, even if it's really a 10 uF (which I still don't believe) instead of a 10 nF.
I don't have any fine magnet wire, either.

Yes Im sure. uf.  I even used 'good lighting' to be sure because you had me doubting my caps that I have used for some time now.  Some are from car audio component speaker crossover modules. I have 2 that are 12k(12uf) 100v and 12uf makes a lot more sense than 12nf for crossover points in typical cutoff ranges in audio.

I did the 'recheck' right here before I replied.

I remember looking at different sites back then for the info to determine these values visually, and not all were helpful in telling me what my meter says. Strange.

If you wish, I can do a short vid of the testing. I have quite a few of these caps around.

No, we are cool, I agree that 10 nF doesn't make much sense for an audio crossover network and I think you know what you are doing, most of the time...

But you can understand my position too, I hope, since I found a couple of references that support the interpretation of 10 nF.

(I guess we should just be glad it's not one of those old rectangular mica caps with the colored paint dots in the little embossed pits, I guess.... paint flakes off, etc...)

Back to the video, with calipers....

@Farmhand: Very nice blueprint schematic. Are your L1 and L2 coils on the same core? Where are the clock signals to the mosfet gates coming from?

Are ya gunna build it?
