Inside one of the foot-spa detox units.
Added 2020-02-24 18:53:05 +0000 UTCI wasn't expecting much in these units. Maybe just a resistor to limit current?
Turns out that somebody has done some serious design on the current limiting circuitry.

2020-02-29 09:00:43 +0000 UTCTraditional power supplies used a big iron transformer running at 50/60Hz. But modern supplies use much smaller transformers for weight and cost reasons. They convert the incoming supply to DC before using it to pulse the small transformers at very high frequency, coupling a small amount of energy across magnetically with each pulse.

2020-02-25 23:41:37 +0000 UTCI use drain cleaner and foil, in a pop bottle to fill balloons with H to let them go with notes, or I did now it is frowned upon here in the US. The system in the video above, just uses electrolysis (like you foot thing) and they put it right in the plant water. (Like it's a new concept) and they are very expensive.

2020-02-25 14:40:41 +0000 UTCInteresting that it is revision 3.1 and the date code on the board isn’t from that long ago. So it isn’t like these are laying around in some factory/warehouse for long periods of time

2020-02-25 08:05:23 +0000 UTCI’ve been watching a bunch of your older videos and have gotten curious about the transformers in the power supplies. A quick search online shows pretty much everything saying that transformers are for AC, not DC, which makes sense given how they work, but in the power supplies you take apart it always seems that the transformers are on the DC side. I’m assuming that a DC transformers works by pulsing the current and using a diode on the output side. It would be interesting to see a video going over this.

2020-02-25 01:53:43 +0000 UTCCommercial HHO gas generators tend to use sodium hydroxide as the electrolyte (drain cleaner). Using the electrodes in water with unknown chemistry could result in unexpected chemical reactions.

2020-02-25 01:17:04 +0000 UTCWhy don't they just run it in a closed box, and pipe the H and o2 into the plant water system, that would take care of the toxins, and the heat, and it could be run with "salt" for more of the precious 02. and could make a Big Bang !
