Hey Guys,
A while back I ordered the parts needed for a PID controller on the temperature for my Breville Cafe Roma.
This may intrest people as I know that some people are paying hundreds of dollars for these things, but with a little electronics Knowledge, I have set this up for a fraction of the price.
Ebay PID controller: $15
Ebay Thermocouple: $2
Ebay Solid State Relay: $5
Parts I aready have: Misc wire/cable, tape, wood for an enclosure, tools etc. (yeah im a bit of a hoarder
Now the PID i recieved had a 3A internal relay, I had to unsolder this and solder some wires so I could hook it up to my SSR, so some electronics knowledge is required for the parts I used.
The last of the parts only arrived last night, so I have only done basic bench tests. I still have to make the enclosure and wire it up neatly.
The temperature before the PID was ranging from mid 80s to about 110 degrees max, which pretty much sucks.
From initial testing, this this is just magical I set it to 96 degrees, it heated to 80 something, switched the element off, slowly got to 96 and then it just blips the element occasionally to keep it at the temp.
I am very impressed with this so far, and provided these cheap parts dont break on me, its a bargain!
I will post more once I have set it up properly!
