This is Jack's occasional outlet for thoughts about designing and programming embedded systems. It's a complement to my bi-weekly newsletter The Embedded Muse. Contact me at email@example.com. I'm an old-timer engineer who still finds the field endlessly fascinating (bio).

A recent article in Embedded Systems Letters made some good points about low-power design, but missed the mark on what's needed, and what tools are already available. Read the rest of this post.

Transmission lines are interesting, sometimes baffling, and fun to play with. Here's a way to make a step turn into a pulse with not a single transistor. Read the rest of this post.

The conventional wisdom is that a very effective way to get higher-reliability software is to have independent teams develop two or more copies of the project from a common set of requirements. Some data suggests this isn't always true. Read the rest of this post.

In September it will be two years since I stopped writing a weekly column for embedded.com. Between that and my earlier monthly articles in Embedded Systems Design magazine I wrote over 1000 pieces about embedded systems. As of this writing 355 issues of my Embedded Muse newsletter have gone out. Then there are the six books I wrote or edited (plus one on sailing). You'd think I would have had enough of writing!
