A lot of my friends ask that last one. Of course, most of them are Jewish, so there’s a history there that’s pretty hard to argue with. I just let them know the technical basics and most are like “Great. Still not for me,” lol.
It’s an atttempted implant that would light up like a xLED implant, but instead of being powered by a reader, it would react to normal household power. 110V A/C power, like what your refrigerator / tv / microwave runs on.
This is where I was working at it.
It fell by the wayside, cause life overwhelmed me. I’ll get back there soon, just gotta finish some stuff up first.
The trouble is, it’ll never work: the frequency is much too low, and the “inductor” (the wire in the wall or wall socket) is not a coil. There’s a reason why transformer primaries are coils wound around a core.
The mains barely radiates enough power for an AM radio to pick up as noise - sometimes - but certainly not enough to light up a LED.
I hate when reality is being a downer, I’d pay for one of these in a heartbeat.
It might be possible to detect AC if sufficient current is travelling through the cable (commercial toaster oven sort of current) but theres a reason all the VoltStick-things (non contact voltage detectors) are active. These companies would definitely go passive for cost and reliability if they could.
