Woke up this morning and while reading my news feed I saw this article titled "7 Best Upgrades for Your Weber Kettle". As a big weber fan I clicked on it and after the tried-and-true hinge, pizza ring then I saw my little black box...so stoked! Wasn't happy with the PartyQ and PitmasterIQ 110 controllers, I started making my own controller with a solder iron and a bare PCB copper board. 4 years later it's the best controller keeping temperature steady for weber kettles and WSM's. Where PID controllers have a hard time keeping the temperature swing minimum in tin metal grills, our linear control algorithm shines. I have to give thanks to Meathead and his Amazingribs.com where I felt like I'm back in my Thermodynamic class back in college...
