Build Your Own BSD Beer Brewing Control System
gnuguru writes "Here's a great use for some of your old hardware, a BSD beer brewing kit! Components: one 486, FreeBSD, a temperature logger kit, a relay board, some odds and ends from the useful box, and some time. Summer's just around the corner, so get to work gang!" You'll have to use this recipe, naturally.
See, FreeBSD isn't dead! Just drunk!
There's something more useful or important than beer?
Shower temperature regulation is one of the things I've been thinking
of for decades. It requires much faster responses than beer brewing,
and to do it right you need to understand the differential pressures
of the hot and cold water. It's a lot simpler to buy a thermostatic
valve.
