- A working Mazzer Grinder (This is what I used and a purchased one that was not working because the time switch had failed; I do not need the timer switch so I got it cheap)
- I purchased this Stainless Steel Dispensing Funnel in the 13cm diameter version and removed the Handle and shortened the bottom.
- I purchase an ESP32-2424S012 device from Aliexpress ESP32-2424S012
- I purchased a JST cable (4 pin 1.0mm) to connect to the esp32 io.
- I purchased a JST cable (2 pin 1.25mm) to connect to an external battery. (optional Will just make the device capable of displaying information wile the grinder is unplugged)
- I purchased a solid state relay to turn on and off the grinder.
