Of course.
I figure I'm not an idiot.
I built a relatively complex "one-off" tachometer for my motorcycle.
Used no diodes and still connected it backwards... (in my defense, the
wire colors were bleached out by the sun, after a few years - but I
should have double checked). The only thing that died was the first
eight volt three terminal regulator - and it died shorted, protecting
the rest of the linear ICs and five volt regulator.
Reverse bias diodes are cheap protection. I am a believer; oh yes,
yes I am.
