A comment on Show HN: A retro video game console I've been working on in my free time. Parent comment
- Being able to detect noise from the system clock crystal oscillator all cross the breadboard (using my oscilloscope)
- Seeing certain I/O pins float to a bit too high of a voltage, when they were supposed to be "low", probably due to breadboard capacitance
- Accidentally making an AM radio when I forgot to connect a wire on an LM386 I was testing as an audio amplifier
Things got a lot cleaner when I went to a PCB, but I did make it all work on breadboards first.
