Reflow toaster making is a very fun and exciting experience and the interest thing about it doesn’t even cost you too much to start this project.

Ok, first thing first, you need to purchase a cheap second hand toaster from WallMart or anywhere you can think of it (It will measly cost you about $50-$80 for it). With the 200 degree Celsius and above, it is powerful enough to melt down the solder paste!

The main objective for this project is to create an embedded system, which will takes in temperatures and actuates a relay that will constantly controls the heating elements.

Oh, you also need a tool called “thermocouple” for this project. Did you say you’ve never heard of this thing before in your life? Well, a thermocouple is a type of temperature probe, where it can withstand very high temperatures (>100C) of the toaster.

You’re better use the 16F88 PIC for the microcontroller as:

  • It’s assembled with an ADC
  • It’s cheaper than other PIC
  • It can be easily boot loaded

After you have all of the require equipments, now you need to turn and off the oven to read the temporary data. [link]
