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...

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...

SGI Granite may well be a nickname and slightly ambiguous, but it's by far the most commonly known descriptor of that keyboard. SGI Bigfoot? Enlightenment? 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...

So supporting a dozen or so keyboards with 8 different matrix layouts in one converter isn't enough for you?! :lol: There are differences in the way WYSE / IBM / ADB drive the lines that make them fundamentally incompatible, and even without that, auto-identify might cause issues. A future Soarer mi...

WYSE Converter
Introduction This firmware for Teensy 2.0 etc. aims to convert all WYSE terminal keyboards which have a 4P4C connector, to USB. See Wyse keyboard protocol (4P4C) for more information about the protocol and the models that use it. (There's also a thread for this project on GH ). Features All of the ...

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!
