Changing a cordless beard trimmer into a corded beard trimmer, because I don't like dealing with NiMH cells.

They wear out every couple years, and it's never at a convenient time; can't travel without a power cord because when I do, they run down. And I always trim my beard in a bathroom, where there's a mains power outlet, so why not just use a cord?

This particular model happened to have an easily-replaceable NiMH cell, which is unusual in my experience. But still - the cell died, and with a dead cell it won't work even when it's plugged in. So I decided to rebuild it my way.

Full description is on my blog.
