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.
Were our leaders just stupid? Well, maybe. But there’s a deeper explanation of the profoundly self-destructive behavior of Trump and his allies: They were all members of America’s cult of selfishness. You see, the modern US right is committed to the proposition that greed is good, that we’re all better off when individuals engage in the untrammeled pursuit of self-interest. In their vision, unrestricted profit maximization by businesses and unregulated consumer choice is the recipe for a good society.
Support for this proposition is, if anything, more emotional than intellectual. I’ve long been struck by the intensity of right-wing anger against relatively trivial regulations, like bans on phosphates in detergent and efficiency standards for light bulbs. It’s the principle of the thing: Many on the right are enraged at any suggestion that their actions should take other people’s welfare into account. This rage is sometimes portrayed as love of freedom. But people who insist on the right to pollute are notably unbothered by, say, federal agents tear-gassing peaceful protesters. What they call “freedom” is actually absence of responsibility.
Rational policy in a pandemic, however, is all about taking responsibility. The main reason you shouldn’t go to a bar and should wear a mask isn’t self-protection, although that’s part of it; the point is that congregating in noisy, crowded spaces or exhaling droplets into shared air puts others at risk. And that’s the kind of thing America’s right just hates, hates to hear. Anger at any suggestion of social responsibility also helps explain the looming fiscal catastrophe.  – Paul Krugman 2020-07-28 NYT

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.
