So I have a project I'm working on a project to light these "NFC fingernail lights":
They light up when in the presence of a 13.56MHz RFID field. The issue is other than my phone, I have no way to light them day to day.
I would like to develop a device I can hold, like fist semi closed and it would light up the fingernails.
I have had some success with a Pierce Occiliator, infact it 100% works. The issue is to get a brightness I am happy with I need to provide ~30v from my variable power supply. For reference here is the schematic of the circuit that worked for me:
Unfortunately given I want this to be compact I don't think this circuit will work for me, or at least I don't know how to tweak it to work better for my usecases.
I haven't had much luck finding anything helpful in the internet. Everything relating to RFID focuses on reading and writing.
Also a stretch goals for me would be to instead have a bracelet that if I curled my fingers towards the wrist it would still be able to power it but I'm not sure how realistic that is.
Any guidance would be much appreciated. I am fairly competent at wiring things up, making my own antennas and that sort of thing but the RF stuff kinda goes over my head.
