| Description | An overengineered espresso machine mod. |
| Author(s) | q3k |
Intro
q3k's espresso machine (Rancilio Silvia) is not in service anymore after he got a new dual-boiler machine for home.
Why not make the old machine an over-engineered workhorse, and maybe keep it at the space for espresso freaks to use?
Planned Features
PID control
Instead of the stock bang-bang control, it should have PID control of the boiler temperature.
Flow profiling
Using pressure sensor(s) and flow sensor(s) we should be able to control the pump to maintain constant flow/pressure.
Remote control/stats
WIFI/Ethernet connectivity for pre-heating the machine remotely / on a timer. Also the ability to see/export brew session data (flow/pressure/temperature graphs).
Cup scale
Integrated (Acaia?) scale for doing coffee-in-liquid-out weight measurement.
Steam wand
Probably removing it, keeping it as a pure espreso machine (also less of a problem to clean).
Electronics
The brains of the operation will be either based around an RP2040 microcontroller or a QF105 Microcontroller (if it works). An ESP32 will be used for Internet connectivity.
Plan
TODO in somewhat sorted order:
- Take apart and clean (DONE)
- Fix pump hose
- Buy pressure sensors (DONE)
- Buy temperature sensors
- Design main control board (waiting for qf105, ETA 2023? :/)
