So I have a project I'm working on a project to light some 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 through my fingers.
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. 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 at the 13.56MHz frequency focuses on reading and writing that I found.
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 / following schematic, also have some experience making my own antennas (thanks to this project) and that sort of thing but the RF stuff kinda goes over my head.
