Towards Realizing the TPU

[EMdevices]

I don't have a meter to measure inductance wattsup, but it sure needs to be tuned just right,  I think mine is tuned in the 20 kHz range or so,  I tried other outlets in the house and it doesn't light so maybe this particular signal is only specific to my place.   I know it's realy touchy on the tunning just like a radio, you have to get it just right or it won't work.  Just using plain induction will not work it needs a capacitor for the tunning to build up the voltage, but if the magnetic fields are high enough I guess a simple coil can do the trick.

Seems you have to retune each time you are close to other outlet. Hmm....how is it then related to original TPU ? I don't see SM adjusting TPU when going outside of house.

@EM

What do you see about polarities?

I doubt there is much power in the signal but if you have a remote read power meter there is a signal in the 10's of kHz used for those.

@EM

I would also like to know about polarity of your ring and simply if the diode LED will work if connected either way, or will it only light in one direction.

Just put another opposing diode/led in parallel there.
