It's not micro-controllers or robots, but I built some shelves tonight to hold a bunch of records and the record player in our basement studio. It's unfinished 3/4" MDF and 1-5/8" drywall screws. I had Home Depot make a few of the big cuts to make the MDF sheet easier to get home, then did the rest primarily using the radial arm saw. Took about 2 hours to build after getting materials.
I wish I had a picture of what this corner looked like before the shelves, even though it looks like I still need more.
