This is my machine that I modified. I have hobbies in electronics, and I have applied it to my other hobby which is coffee. I am a high school student who has applied for electrical engineering at several universities. I added 2 PID controllers which regulate the two individual boilers in the machine. One for the brew boiler and one for the steam boiler. The controllers initiate the solid state relays which completes the AC circuit to the heaters attached to the boilers. I can set the temperature of the boilers to whatever I want. The temperature is regulated constantly at my desired set point; this allows me to replicate good espresso shots every time. Also the digital timer allows me to pull espresso shots automatically so I do not have to manually turn off the pump. The cost of the total project was 0 which is an extremely good price for a dual boiler espresso machine. (I bought a used kitchen aid pro line dual boiler espresso machine(parts made by gaggia). The cheapest dual boilers cost 00 on average. I actually own 2 retired commercial grinders. One is a astoria super Jolly (as seen in the video) The other is a Rossi RR45 (not in the video; its in my school's shop, designing another 3d print chute). A good grinder is essential for high quality coffee as it ensures all coffee particles will extract at the same rate. The cheapest grinder for espresso will require you to spend a minimum of 0. FYI my grinders average around 00 a piece when purchased new ...
