Bluesky is where you find the people who think they ought to run the Internet.

Well, I just got laid off from my job. If anyone needs a talented embedded systems engineer or hardware engineer with strong experience in video hardware, send me a message with details of a job opening and I can provide a CV. Remote work preferred, but I can work anywhere in central Minnesota. Boosts welcome and encouraged.

My first die shots. You can see a lot more than I'd imagined without a microscope. This is a 1:1 macro lens, and just changing the angle/size of the light source gives you a ton of control.
