Improving the Beginner’s PID – Derivative Kick
(This is Modification #2 in a larger series on writing a solid PID algorithm) The Problem This modification is going to tweak the derivative term a bit. The goal is to eliminate a phenomenon known as “Derivative Kick”. The image … Continue reading
Improving the Beginner’s PID – Sample Time
(This is Modification #1 in a larger series on writing a solid PID algorithm) The Problem The Beginner’s PID is designed to be called irregularly. This causes 2 issues: You don’t get consistent behavior from the PID, since sometimes it’s … Continue reading
Improving the Beginner’s PID – Introduction
In conjunction with the release of the new Arduino PID Library I’ve decided to release this series of posts. The last library, while solid, didn’t really come with any code explanation. This time around the plan is to explain in … Continue reading
Arduino Uno Keeps Header Offset
The newest version of the arduino was announced last week. At first glance it seemed as though they got rid of the offset header spacing, but a closer look at the spec showed that it is still 0.16 inches. It … Continue reading
Success!
Constant Air + Constant Heat = Constant Smoke. Who knew? Constant Air Holes. There were tons of holes. To have complete control over the air I had to patch them all. Most of them were fairly easy. A little JBWeld … Continue reading
DIY BBQ Smoke Generator – 2nd and 3rd Attempts
I’ve had a few more gos at making smoke and, well, there’s still work to be done. 2nd Attempt There were two main issues with the first attempt. The smoke was intermittent, and I needed to manually shake the ramp. … Continue reading
Sparkfun Now Carrying Offset Headers
The title says it all. Their picture is much nicer than mine too. That quarter or theirs really gets around. Here’s a direct link to the product page.
Arduino Offset Header
The Arduino has a problem. Not a big problem by any means, but still annoying under certain circumstances. As the story goes, an 11th hour design mistake has left the Arduino community with a header that doesn’t follow standard 0.1″ … Continue reading
PID Front-End v0.2
Some people spend the 4th of July relaxing with friends, drinking beer, enjoying some good weather. I… updated the pid front-end. I got several requests to add grid lines and axes, and now was the time. For those of you … Continue reading
Arduino Reflow Toaster
Pic 1: Arduino Controlled Toaster-Oven. No, I have not tried making toast with it The Mark 1 reflow toaster is complete! (“Mark 1” is another way of saying there’s a lot of work to be done.) It can hold +/- … Continue reading
