The Smart Grind-by-Weight is a user-friendly, touch interface-driven, highly accurate open source grinder modification that can transforms any grinder (with a accesable motor relay) into an intelligent grind-by-weight system. Originally developed for the Eureka Mignon Specialita, the system can be easily adapted for other grinders.

The concept is simple: Perform a "brain swap" on your grinder. Replace the original controller with our intelligent ESP32-S3 controller and add a precision load cell to the mix.

Upgrade cost: €30-40 in parts
Target accuracy: ±0.03g tolerance
No regrets: No permanent modifications, and original grind-by-time mode is also available
