- I think the most important skill for making hardware is just having a good fundamental understanding of electricity. Just developing an intuition around Ohm's law gets you remarkably far in terms of developing and debugging circuits. Towards that end, Khan's "Introduction to electrical engineering" and MIT's 6.01SC Unit 3 both look great.
- For this specific project, I needed to program an FPGA so I drew on my college experience (18-240) where we learned about FPGAs and Verilog. Coursera's "Introduction to FPGA Design for Embedded Systems" looks like a good option.
- Don't be discouraged by hardware tools. Coming from a software background, using hardware tools is like traveling to a foreign land where good UX is punishable by death. At its core, designing PCBs is really just drawing 2D shapes, and it's striking how painful drawing is using hardware tools (eg Eagle, Kicad) versus how delightful drawing is using artistic tools (eg Sketch, Figma).
