I got a math minor with my CS major 15 years ago, and just started sending applications to MS CS ML/AI programs. I really need this now to relearn linear algebra etc, and your site is really bringing things back quickly.
I’m not doing the coding exercises (yet), that’s just me for now, no feedback there.
I did have some feedback when I was reading last night, will send a PR when I have time.
I’m creating an electronic avionics sensor and display for experimental aircraft. I’m having a fantastic time learning about circuits and MCUs (I have a pure CS degree, zero background with EE stuff). I’ve been working on this in my off hours for over a year now, maybe someday it will be a product that people buy!
The current challenge is the display. I’ve struggled to learn about this part more than any other. After studying DVI and LVDS, and after trying to figure out what MIPI/DSI is all about, I think parallel RGB is the path forward, so I’ve just designed a test PCB for that, and ordered it from JLCPCB’s PCBA service.
