It's dead-dead. This Dyson motorhead broke shortly after we bought it. Dyson warrantied it and sent a new one so here's the broken one. Input fuse was blown but even after replacing that, the power rail is still shorted out. Nothing else obviously blown. Board has conformal coating so hard to debug.

One of my cans of Plastic Wood rusted through. It's not that old but I guess it's pretty strong stuff.

First room complete. Started with the small squarish room. Only gets more difficult from here.

Over three years later, it was time to replace my phone case.

Installed the replacement.

Bought a garage door opener and it wouldn’t turn on. Could hear a loose part inside when I shook it. This part has solder on it but was not connected. I pressed it into place and it powered on. If it wasn’t brand new I would’ve soldered it myself but I have no idea how it made it out of the factory.

Gotta love 3D printing. Found these designs online and was able to modify the vacuum so it could actually hold the pieces.
