Village Idiot looking for light aka trying to wire Model M terminal to LEDs
« on: Fri, 04 April 2014, 15:34:06 »
Hi Folks!

I am looking at the back of my M122, trying to find places that I can wire up to LEDs.

Does anybody know if there exist traces for LEDs on this controller? It's just a little project I might undertake.

I would love to have a LED on my SSK for Num Lock, like the RF TKL boards have. It seems every time I turn on my computer, and need to type a password to unlock, it starts up with Num Lock on, and there is no visual representation letting me know this.

I thought that the Teensy has a few connections for this, if you are using a Teensy.

Actually, I do have a teensy adapter. But I was wondering whether something could be done on the board itself. Am in the mood to cut some holes in the casing, just because it's there for me to cut.

likely not: there's no output from the chip for LEDs. There's a chance that the non-soldered part on the left of photo#2 was for LEDs, but since you don't know what chip went there it won't help.

I recommend an internal teensy for LEDs and programmability.

So far the stuff I've seen from other people are for external teensy with pins, and LEDs stuck on the breadboard.

If you use an internal teensy, that means running wires from the teensy to a little LED-PCB (or whatever you call it) mounted at the cutout holes in the casing, right? That means I'll have to find a little LED-PCB (or whatever you call it)?

You can probably chop that piece out of a worthless rubber dome keyboard PCB before you toss it into the garbage.
