this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....
Hello Tilman, this is really a very nice design. I have ordered a pack of PCBs from elecrow, based on your gerber files, and have a few questions:
in your BOM you have listed 5 smd-capacitors and 7 smd resistors, but on the PCB i have solderpads for 6 capacitors and 8 resistors. Can you just explain?
is there a uniflächentaster-model for 2 ways?
i think i have to flash the bootloader first, do you have a tutorial for this, and a sample-sketch for the board?
Thank you very much
@martinhjelmare
Wow thank you so much.
I've cleared the eeprom and now it gets node id 1. After removing the persistence file the sensor now shows on the web interface.
@JahFyahh - I still haven't managed to et round to it. I've been really busy since this project and its still hectic here. I'm sure i read a few reviews somewhere, here or google. Not sure.
