Maybe you would enjoy “Every tool’s a hammer” by Adam Savage.

The small board that was above the numpad has all the smarts for the whole keyboard, so I had to follow the traces it was attached to and find a new location to wire it in at. Luckily the big PCB I cut in half is pretty simple so I could just visually see where everything went and run a new wire there.

I guess that’s debatable, I just wanted the mouse closer ;)
