Has anyone seen Lasersabers new motor runs on 1000uf cap

[Magluvin]

Hi Mags,

Just my speculation,  perhaps Lasersaber buried one more reed and one more diode in the motor structure, then using the schematic in the link (very first post by Lanenal) the capacitor charging from the flyback pulses becomes possible:

Of course, careful adjustments for the reeds are needed to insure their simultanous switch ON or OFF operation, not an impossible task.  In the schematic a double reed is mentioned and I know Lasersaber referred to single reed type (SPST) as a substitute for his older reed type used.  Obviously a double reed can be substituted with two single reeds.

Hopefully he will reveal his schematic used, sooner or later.

Perhaps, but thats not what he said. So I wont speculate on that beyond what he has shown.

Like I just posted to TK, that diode is in series with the cap.  A one way street. So how do we have charging and motor function with all components in a series loop?

"The cap in Lasersaber's video is marked 10K 100. A poly film cap of that size cannot possibly be 10 microFarads."

hmm, your gunna have to recheck that. I have 2 caps in front of me, one a white box plastic and 2 blue drop caps, the blues say 4.7k and 22k both 100v and the white says 8,2k 100v and they read as uf respectively.

So you might want to redo those calculations.

Yes, my understanding on the 10K in case of poly caps is that the K means rather tolerance than a 1000 time multiplier.  The multiplier is designated differently like say 103 and it means you have to add three zeros after the 10 but normally this is valid for cap values in range from pF to nF, so 103 means 10000pF i.e. 10nF,  however in the uF range the "habit is writing the pure cap value number WITHOUT including uF.  So 10 means 10uF. I have also come across with such cap like Mags.
I think K means tolerance and nominally designates +/-10% tolerance. MAybe the letter J means +/-1%, not so sure etc.

EDIT just found the manufacturer of the poly cap, http://www.illinoiscapacitor.com/pdf/seriesDocuments/MWR%20series.pdf  However in its last page I noticed 106 designation for the 10uF cap  so they may have changed their habit (I speculate).

Well, a one way street indeed LOL  Earlier I thought of a Zener diode there but he mentioned germanium diode so... we have to wait. 
(A zener diode in its normal forward direction for the motor function and say with a 4.7V reverze breakdown for charging up the cap, allowing 4.7V loss from the flyback pulse. MAybe I am wrong here...)

Edit: yes I am wrong because the reed is open when the flyback is coming...

hmm, your gunna have to recheck that. I have 3 caps in front of me, one a white box plastic and 2 blue drop caps, the blues say 4.7k and 22k both 100v and the white says 8,2k 100v and they read as uf respectively.

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.

The dimensions of their 10 uF, 100 V cap are 18 x 34 mm. Seems larger than what's shown in the video. And they don't list a 0.01 uF at 100 volts. So I dunno, maybe.
I've found other sources that say a cap marked "10K 100" should be 10 nF not uF. But I'm willing to allow a 10 uF capacitor. It would be a lot more plausible in terms of energy content, that's for sure, turning that little rotor for some tens of seconds maybe.
