Blade Detect Wiring For Crystal Chamber

Hello all,

I’m planning a Goth Grand Master build that I would like to switch fonts based on:

  1. Crystal 1
  2. Crystal 2
  3. No crystal

Generally behaving in this manor:

I understand that I can add resistors to the crystals with blade id to handle the font switching and I think I’ve got a handle on that, but I would also like to utilize blade detect to use the in out sounds of the crystal being inserted/removed.

What I’m not clear on is how I would wire up the crystal for blade detect. I understand that normally blade detect works on the npxl pcb by sending that pin to ground when a blade is inserted. So I need to use one of the pins on the crystal/chamber to send that to ground instead?

Any help is appreciated.

Blade detect is just a simple switch or connection that is connected when the crystal is there and disconnected when not.

It’s also possible to use RFID for these sort of things.
