Arduino PID Autotune Library
At long last, I’ve released an Autotune Library to compliment the Arduino PID Library. When I released the current version of the PID Library, I did an insanely extensive series of posts to get people comfortable with what was going … Continue reading
Collapsible Knitting Needle
I needed a break. I’ve been working hard on the osPID for several months, and I just needed to not look at code or control algorithms for a little bit. Nothing says “break” like an out-of-left-field project. I only started … Continue reading
PID-Controlled Espresso Machine [PID Showcase]
It is to my great delight that I can confirm that this Kick-ass, Kickstarting, Open Source Espresso Machine is using the Arduino PID Library. They seem to be using a stand-alone commercial pid controller for at least some of the … Continue reading
Introducing the osPID
About 5 months ago I sent an out-of-the-blue email to RocketScream electronics asking if they wanted to help me build an open source PID controller. It’s been far more challenging than I expected, but today I get to announce the … Continue reading
PID Library moved to GitHub

A Little Teaser
I haven’t done many PID posts in the last couple months. Rest assured I haven’t been sleeping on that front. I’ve been working closely with RocketScream on an OSHW project that should be released soon. Here are a couple teaser … Continue reading
Making a Custom Bottle Opener
I recently posted an improved bottle opener design to Thingiverse. Unlike the mighty bottle opener, this is one that I’m proud to give out, and people are happy to receive. Because I did the model in OpenSCAD, it turns out … Continue reading
