Gaggiuino community for espresso DIYers modding machines with custom controllers and PID tuning.
Coffee tinkerers gather around the Gaggiuino project to add temperature control, pressure profiling, and custom electronics to their espresso machines. Members share wiring photos, troubleshoot builds, and dial in shots once the hardware's done. It's a delightfully specific crossover of soldering, software, and the pursuit of a better cup.
