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.

Bush’s original tax cuts. This is the year everything reversed. Before this, under Clinton, Bush and Obama the deficit in almost every year was gradually decreasing. The balance we had of taxes and the economy was bringing the deficit down, the money coming in was slowly catching up with the money going out until 2015. Trump’s subsequent tax cut has continued the new trend even after the rest of Bush’s cuts have since expired. Obama had an average GDP of 2.3%, with 11.6 million jobs created and unemployment peaking at 10% in 2009, then falling to 4.3% in 2016. If we had continued on that downward deficit track, we would have again reached balance and another surplus in 2017-2018.

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.
