I wanted to create an implant that uses an LED to charge glow powder.

I used strontium aluminate glow powder, the NTAG I²C chip, and tried different LEDs.

First i tried just using two leds attached to a coil
But since there was no IC detected by the reader it would only blink very slightly
but it proofed that the concept works

I got myself some Ntag I2c Chips and soldered everything to its pads which was tedious but worked

SilentPotat0 designed this pcb (Link to Gerber Files) so i dont need to solder directly to the chip anymore

Chip used: Ntag I²c
LEDs used: UV 390nm 0603, Violet 0602, Blue 0602

Getting better and better

Got some Flex Pcbs so i dont need to manually sand every pcb to dimension so it fits the tubes

This is an implant without the glow powder added to the resin.

Finished implant was finally implanted
