I can't believe it's been over a year since I first mentioned my sous vide project! Ugh; I'm so discouraged.
I actually have made some progress on this project. In the past year I've prototyped the circuit, I've written the software, and verified that it does, in fact, work. I haven't documented any of that on my blog, though. I've been wanting to do some tutorial-style posts on this project and have drafted three or four posts in the series but I need to get in the workshop and take some pictures to go along with those posts, and the workshop has been a mess. (There's progress on that front, too, but that's a separate post.)
Yesterday, I ordered parts from Mouser for my sous vide controller. I'll lay out a circuit board with those parts and order boards, then build a real, actual board. Hopefully that'll take less than a year!
