I keep a few old phones as spares but if I don’t use them, they get recycled. I have a ton of electronics that aren’t used, but could still be for the right project. It’s nice to have parts whenever you need them.

Depends, if there are recognized certifications those always help. Otherwise, your previous work does matter. I’m sure it’s a terrible experience, but it’s still possible.

If there is something you want, create it. Lemmy is new, and there are not a ton of people posting. Someone will need to do it first.
