USB laundry machine for tiny (moist) Chinese panties.
This is a USB powered washing machine for doing your laundry. Ah, but wait.... Can a USB power supply really deliver enough power to do that?
No. But it does put on a show and it would certainly swirl some lightweight items like socks or sexy panties around in a bucket or sink. However the load capacity of 10kg stated on some listings is highly improbable.
The "ultrasonic" cleaning function is notable for using a vibrator motor and being completely not ultrasonic.
The circuitry is fine. In fact it's pleasingly minimalist to the point that reverse engineering it was fun due to the wide variety of transistors matched to each motor and the way the circuitry was optimised to use the 6 I/O pins of a cheap processor.
If you really want one of these short lived panty whirlers then there's a search link below. Note that some seem to have wisely removed the air function and just have a simple cable going to the agitator. Hopefully that will make them more water resistant.
Prices vary between styles. I don't really recommend these as anything other than a novelty.
