therm

Therm rev2 is up and running! I don't have any photos of it actually powered up at the moment, but I have it running a sous vide setup to verify that everything is working properly. Software has been ported to the new micro and basic temperature reporting over a USB virtual serial port works as well.

Since my new micro does not have EEPROM, I need to rewrite my save/restore functionality to read and write from flash. Once I wrap that up along with some other tweaks, therm should be completely usable!

I'll add photos of the updated design and links to source in the coming weeks.

The second revision of Therm is out for fabrication! I included breakaway mounting tabs and switched to a new (smaller) processor. More updates will come soon...

The first prototype therm board is up and running! I currently have it regulating the temperature on my espresso machine. Thermocouple readings seem much more stable than my last design based on the MAX6675, and a faster PID loop has greatly increased temperature stability at rest. I'll post some photos and more information soon.
