- lmilcin 9y agoI am using Rancilio Silvia. It is well built machine but has absolutely no electronics and it is easy to disassemble and plenty of free space internally which makes it perfect for experimentation. My research of mods that are described on the Internet shows that most people put some kind of existing PID controller, SSR to control the heating element and a temperature probe which gets mounted on the outside of the boiler. Minority is using Raspberry Pi, Arduino or some other kind of existing microcontroller board to allow for nice display and more functionality. Few people are doing completely custom boards which is what I am doing for this project. I am currently learning electronics after almost 20 years in software and I find it very good exercise from design perspective.
