I do that same thing. Earning around $100 an hour, and I can do as many hours as I want, whenever I want to. I do this on top of my full time job, so I usually do a few hours at night or a weekend day here and there. That's similarly in the $60-70k extra per year.

What I do is embedded software for medical devices though, so beyond building there's a lot of documenting, reading documentation adhering to standards.

I'm looking to do exactly this. I'm currently doing embedded software for aerospace, so somewhat similar with regards to documentation and standards (it's critical software, just not human safety related). Can you share how you found the work?

I'm also curious to know how you can do small quantities of hourly work in this field rather than take on projects that would require much larger time commitments. Are you just consulting as a domain expert or something?
