Maybe something like this? The LED would be connected to 2 resistors, so it would glow dimly, until the switch makes a connection that bypasses one of the resistors so it can run at its maximum spec. Trouble is, although that would change the current flowing through the LED, there isn't an easy way...

If you scan the rows and columns, you could illuminate any individual LED or set of LEDs. Perhaps have each key light when pressed, or backlight the entire board, and have the key extinguish when pressed. Well, of course, but you'll be adding a fair amount of circuitry and/or specialised driver chi...

For 'on all the time' you can wire to one of the two +5V pins on the Teensy and draw up to the USB limit (minus a bit for the Teensy); no need to extend and tap the USB cable itself. Even 5mA per LED would be too much really (well, how many LEDs?). Aren't you still thinking about the mA rating wrong...

Yeah, well, they often just switch the LEDs with a FET that can take the current. PWM and bigger resistors have the same effect - reducing average current, and reducing brightness. PWM might not be the best choice if peak current is still over the 500mA USB limit! Don't forget, manufacturers shave e...

Whatever, this is not a debate I'm willing to continue. If the answer to "Why not call it 'SGI Keyboards'?" is that SGI never actually made any, then you could just say so instead of posting childish insults.

No, I wasn't being sarcastic, it just seems the logical way to go if there is any uncertainty about the manufacturer. Are you certain that all these SGI Bigfoots are simply rebrands? Were the Granite Bigfoots made by Alps using SGI's special granite sauce plastic, or did SGI have them made separatel...

Of course it's "precious" - a decent layout, Alps switches, and PS/2 interface all combine to make it so. Do you actually know that the Indigo² models (part numbers 9500820 and 9500829) are not PC compatible? Are they not in fact PS/2? The only difference that I know of is the colour. There's a non...

SGI Granite may well be a nickname and slightly ambiguous, but it's by far the most commonly known descriptor of that keyboard. Why is that keyboard special? It just seems like a "precious snowflake" problem, that it has to be segregated because it's "pretty". It's not special for being PS/2, or Bi...

No. Now that we know of the nickname Bigfoot - for a group of (generally?) Alps based keyboards - then of course there should be a page that exp...

The data signal could use any pin, but for my code the clock signal needs to be on an pin capable of generating interrupts on both low-high and high-low edges. So that's one of PD0..3 or PE6, on an ATmega32U4.

Sould be fine to connect that directly, and use something like "unstrobed -PB0 F1" in your config. ('-' because it will go low when pressed). You might need to adjust your debounce settings to suit it.

You're gonna kick yourself :( This is Controller, not Converter!

Can't promise when anything KVM friendly will come along (pretty busy at the moment), but haven't forgotten about it. I guess we could try a test first that simply removes the NKRO/Media endpoint.

Has anyone heard from fossala at all since June? I emailed his paypal address a few days ago, but no reply.

He still owes me (and presumably others) IBM/Alps boards from the second round of him proxying them.

Not sure whether to be worried about him, or just annoyed that he wandered off!
