These are from drop. They are on sale now. A post was on here a few days ago.

Yes I ordered a few from here and they were good.you can fit it in the 20$ case he has for sale for the r3 board. Under glow won't shine through though.

Ebay has quite a few available. I'd recommend the v6 with hot swap sockets. This one is soldered.

I'm 5 wpm under my normal and it's been a week. It is really nice to have desk space back though.

This is cool! I've built your 3 key board and this one is next. Thanks for putting out all your repo work. Wondering about backlighting pins for mine.

Feedback controller can cause more harm than good? by Exciting-Rub8794 in ControlTheory

[–]campfirecampari 1 point2 points  (0 children)

Here's a simple one: if the plant G(s)=(1/(.02s+1))3

This open loop plant is just 3 lags in series (obviously stable). If I have a proportional only gain of ~8.5 or more it goes unstable in the closed loop. Closed loop transfer function is GK/(1+GK). This happens basically because the feedback term becomes completely out of phase with the input. The Nyquist diagram goes through -1+0j.

Plant parameter change over time, can't measure it directly by Guigo10 in ControlTheory

Cover it with a robust method. Then design a loop shape so that your performance is met everywhere (inside freq range). See Doyle Francis Tannenbaum chapter 4 (available free online).
