Thus far I have no real project logs. I have acquired most of the hardware components I'll need, and I've experimented with the RPi to learn how to interface with the SSRs and the temperature sensor. When I am able to spend more time on building circuits or writing code, I'll add more log entries.
I purchased a switchable 18/24VAC wall-wart transformer so that I could begin building my power supply, but apparently I got a dud. And of course I can't take it back because I clipped off the interchangeable tip socket instead of getting the tip with bare leads. So I'll have to open it up and try to fix it.
