I see it much bigger (AA, R14?).
Can someone hypothesizes why using such a high capacity battery when it is (supposedly) perpetually refueled? A button cell or a capacitor (not even a supercapacitor) should be enough.

Impedance of battery.  Large Cap and very small battery should work though.

Just checked ORBO site, they have reschuled the demo to later next week due to the weather!!!!!

Has anyone ever wondered what that knob that looks like a micrometer handle does on top of that machine.  I always assumed it was for timing adjustment, but I wonder if it is a loading adjustment to adjust the phases of the two fields?  Also, they have $7-800 dollars of plastic in that thing on Ch. 1, man it is massive!

Hi Ben,
The Micrometer a Mitutoyo Micrometer head series 149 carbide tipped, can be used to adjust the ceramic ball ( as contact surface to the top of the vertical rotor shaft) So the “sweet spot” of the magnetic bearing relative positions can be finely adjusted.
Yes, that can be an expensive setup for the avg builder.
In the other video just the DPO 7104 new, would run you well into the high 20k or low 30K USD depending on options. Pretty high end equipment and way out of reach for the avg builder out there.
I hope this helps.
Thanks for your contibutions
Mike
