Ten years in Las Vegas

Starting with the move from our dorm to an apartment in Watertown, Massachusetts, Pololu has moved or expanded ten times.

Thoughts on Open-Source Hardware

As open-source hardware (OSHW) has become more prominent over the past five years or so, I have heard questions about where I or Pololu stand on the subject. Most recently, I got into a bit of a discussion with Phillip Torrone of Make and Adafruit on one of his blog posts, and his questions and subsequent interview pushed me to try to organize some of my thoughts about OSHW. Because there are many aspects to OSHW, I don’t have a simple conclusion like, “It’s great!” or “It’s the future!” or “Pololu will never release an OSHW product.”. I am skeptical of some of the claims by OSHW proponents and of the significance of the more organized aspects of the OSHW movement. However, what is going on is very significant to me because it affects Pololu’s business and involves issues I care about a lot, such as freedom, creating things, and education. Continued…
