Welcome to, the Internet presence of James A. Langbridge. Here you’ll find more about me, what I like to do, the work that I do and a few random thoughts and rants in my blog section. You can read more about me, or maybe read some of my rants and raves about my life, and the projects that go with it. My CV is also available, if you are curious.

I’m an embedded systems expert and author, working as an independent consultant.

For some useful Linux hints and tips, see the hints section. There are also some articles on hardware and some other postings in the articles section.

I spend most of my time developing embedded C systems, and providing training for C, assembly and Python. When not developing, I love to write, and I’m the author of an embedded ARM book and a book on Arduinos. was, originally, a site on computer security, one of my passions at the time, but a passion that took far too much time to be able to do anything serious. From time to time you might see a few lines of code, my second passion – software development. A few projects have been labelled Packetfury, and one of these days I’ll upload some projects to the site. In the mean time, feel free to have a look around, and don’t hesitate to contact me!
