Is it possible to do very few key Fn logic? I'm playing with the idea of different Fn layers, yet I want most keys using plain Fn(0). Specifically, I want a toggle layer to be used on certain keys you might not use in everyday situations, Fn1 by doing Fn+alt. What I was wondering if there was a way ...

How are you planing to use the shift registers? Well, I was thinking I was going to go with 7 PISO shift registers, each with (up to) 8 inputs daisy chained together. Like the image attached (the less saturated blocks are the shift registers and use the keys they touch as inputs, the brighter blue ...

OK, so looks like you have given up on the analog approach to scan keys. I think it is an interesting way to do it but also a way which is hard to do right. As for as chained shift registers. I already saw some thread where they wanted to do it that way. Either here or on geekhack. Essentially a 1x...

Just an update on this, I haven't been able to do any testing on this because my connections on my breadboard are really poor (because jumper cables) it was hard to get a stable voltage. I've done some research and am thinking of using daisy-chained (8bit, parallel-in/serial-out) shift registers (th...

that is exactly how the new cherry switch is configured to work. The result is a "zero-delay" keyboard, very interesting but you need a custom firmware and I wouldn't know how to help you with that. please keep us posted if you intend to proceed that way, but honestly the standard matrix is super e...

If you're willing to go to these lengths, you should at least consider making it a straight matrix rather than staggered. This means you could re-purpose some existing switch plates and save a fair bit of either custom ordering or custom construction. What do you mean by "switch plate"? The keycaps...

Advice for building a fully custom keyboard
Hello, After using a chiclet-style dome keyboard (which, having never used a mech keyboard, I don't mind. essentially it is an unbranded version of this ) with a 2-3key rollover (CR:3 on Rajagra scale @geekhack) that came with my computer for so long, I started wanting a new one. I realized that mos...
