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
When a Maker Gets Married
I got married a couple of weeks ago. We did all the planning / decoration ourselves. By we, or course, I mean my wife. One of the things she wanted to do was have lit paper lanterns suspended above the tables.
The initial plan was to use throwies, but I felt they wouldn’t give as much light as a commercial 3 LED solution. This led me to a fun, albeit time consuming project.

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
This changes everything

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

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
A Robot that makes things!
There was an immense amount of work that went into getting to this point, and I can only stake claim to a tiny portion of it. It was really cool to see our Makerbot throwing down the plastic… on the … Continue reading
