Re: White label Model M flickering LEDs

So the leds flicker, but otherwise the keyboard works well? And you can still turn them on/off by pressing numlock/capslock, but it just flickers?

Do you have a video of the flickering?
Do you have an oscilloscope to probe around with to see where the flickering is coming from?

Re: Broken via on Model F sensing PCB

You took a picture of a couple column pins. Those are only connected on the bottom side, and we can't see on this picture if and how destroyed the pads are on the other side. Assuming pad pad looks good on the other side, you may still be able to solder to it SMD style. Pads can be lost for various ...

Re: Model M Requires Hard Key Press on S & F Keys

Try to remove the spring, and put it back on. (Or replace it if you have extra springs). There's various methods without doing a full bolt mod, like: https://www.youtube.com/watch?v=SnBsDeKs54w What I do is simpler, I just rotate the old spring counterclockwise, and pull to remove it. It's a bit cou...

Re: Need some help with my Mextel Autokey 40

I got one of these, and just tried it.

Re: New Compact Beamspring controller available

Yes, my code runs on all xwhatsits, even original xwhatsit boards, and on the "wcass" boards that are in the new Model F reproduction keyboards from Ellipse, and also I believe Ellipse switched over to sending out keyboards with my code by default.

Re: New Compact Beamspring controller available

Is your project the only xwhatsit port to qmk, or are there other ones? As far as I know it's the only one. The only other technology that can drive Beamspring / Model F keyboards, that I know of, is DMA's Common Sense. I believe that it uses a Cypress psoc, and that there's an ARM in it. And doesn...

Re: New Compact Beamspring controller available

is there a version of the xwhatsit code that works with the arm version? As it is, it won't work on non-avr architectures, because it uses inline assembly to precisely control the time elapsed between when the column strobe is triggered, and when the rows are sampled. However you can write your own...
