I plan to make a pre-heater for my SMD works, and i will need a controller for the air heater. From my job i know the PID controllers and how efficient they are, but i did not really know how they work. After some research i did, i sound the “secrets” of the PID systems (and i also wrote a theory for PID systems). So, now i feel ready to turn theory into product. Many will say again that i could spent $40 to get a PID controller… Yes, i know… But i DON’T want to. For me, making projects is not a chore, it is my hobby, i do it for fun.

K-Type Thermocouple PID Controller - [Link]

This DIYThermocouple project uses a MAX6675 chip and takes the millivolts produced by a standard K-type thermocouple, amplifies it, and spits out the results to the attached LCD screen. This particular unit can read temperatures up to 1800 degrees Fahrenheit which is probably hotter that you ever want to be near with your electronics. [via]
