Title: can someone figure this out and build it?
Post by: damzam12 on January 01, 2025, 04:04:59 pm

Admin Edit: Video Removed, user is just spamming the video to drive up views

referring to this video id like 1k or 5k of these circuit's made and combined to power a usbc pd board with all or the protection features and a battery connected. how much would this be?
and how much energy can we expect to get from this configuration.?

And how many more times are you going to spam this crap?

Are you trying to drive up traffic for that junk Youtube channel?

Do you realize that it "harvests" energy that is in your house, so past the electricity meter? There is no free stuff, this circuit creates load. Normally it is minuscule and does not matter, but if you plan on building something that produces substantial output, it will draw substantial input as well.

Just plug in the wireless charger and you will get a way more efficient version of that and you won't need 5000 of them.

Napkin math from the other thread said 25uW of power.... you would need 40k for 1 watt... or 600k for 15w phone charger.  (I may be wrong, it's new years day :P) even at wholesale pricing of components, that's expensive power.
