Last time i researched adding shift registers was over a year ago and I didn’t find many examples (I vaguely recall one possibly with qmk), and very little public discussion besides a reddit question. Popular guides like ai03’s at the time recommended upgrading to a microcontroller with more gpio before introducing shift registers.
Edit: You could avoid using diodes, but diodes increase the number of switches possible via a matrix more than shift registers do by giving you more gpio. I’d imagine one can use both together.
I also hoard information. Keeping a stream of links where I go back to a small percentage. But I find that it is a good habit for me. The links are a slice of the pages that I actually care about.
Though, I wish for a way to index and search specifically within my stream of links. So that I can better recall content that I have glanced at in the past.
I’m assuming DDA stands for demand/direct deposit account. Keeping a separate one with a low balance for internet accounts can help keep a primary account unaffected if paypal or other internet services initiate a transfer without your permission (could also be due to a compromised paypal account).
Searching again, looks like zmk added support for the common 595 shift register: https://github.com/zmkfirmware/zmk/pull/1325
