==Hardware and Software == | |||
===Chillmon=== | |||
* Have Chillmon persist state (temperature set point, PID constants) | |||
* Rebuild Chillmon on Occidentalis | |||
* Configure Chillmon application to use shared account | |||
* Replace temp sensors with DS18B20 for more accuracy | |||
* EPICS integration: | |||
** Expose Chillmon control variables to EPICS | |||
** Create EPICS control screens | |||
** Investigate EPICS web interface | |||
** Display screen for Chillmon | |||
===Brewing Station: One=== | |||
* Electrical insulation of contactor terminals | |||
* Experiment: When the chiller turns off, does it blow hot air into the fermenting space? | |||
* Experiment: In the winter, will the shop drop below our fermentation temperatures, and will we need a heater? | |||
* Real time monitoring of temperature, specific gravity | |||
===Brewing=== | |||
* Modify Keggles for brewing | |||
* Build RIMS or HERMS | |||
** Propane solenoid, thermocouple, and igniter under PID control (Arduino) | |||
** Pump, flow meter run by microcontroller (Arduino) | |||
** Multiple temperature probes (Arduino) | |||
** Safety gear: | |||
*** Alarm system (stuck flow, propane flame blew out) (Arduino) | |||
*** Emergency shut off switch | |||
** Raspberry Pi controlling the above via EPICS | |||
===Dispensing=== | |||
* We have a donated refrigerator; convert to kegerator | |||
** Determine location of critical components so we can safely make cutouts for beverage lines without destroying anything | |||
** Build internal structure to hold Cornelius kegs | |||
** Modify thermostat to keep beer at cellar temperature. (A second Chillmon?) | |||
** Consider plumbing water line for water dispenser / ice maker. | |||
* Add draft tower to the PS:One bar | |||
** Build draft tower and faucet system | |||
** Engineer beverage line and faucet chilling | |||
