Hello all! First of all, thank you for all information gathered it these threads. I learned so much, mostly important food safety protocols and guidelines. I'v made my SV setup myself. I used 1kW bucket hater for heat source, beer can for should so it would not melt container and bags, small submersible pump for circulation, MAXIM/DALLAS DS18B20 digital temperature sensor, Arduino for control board and mechanical relay. So far I'm satisfied with performance, and I can control every detail of algorithm as I coded it myself. Bonus feature is that board can control multiple bathes at different temperatures. I'm planning to add Bluetooth module to control it with my phone - I think it would be nice with presets and timers.
