A few years ago, I realized I had a shoe box with several Raspberry Pi single-board computers just sitting around.

I came across an article saying that interfacing something called a “DHT-11” is a rite of passage for Raspberry Pi users.

I got a fancy magnifying glasses headset with LED spotlights to help me build a small Z80-based computer kit

Sometime when I was in 7th grade, at Ophelia Parrish Junior High school, a couple of guys that I knew showed me Northeast Missouri State University’s teletypes.

An interesting popular geology and paleontology book. Long, but it has a lot of great ideas, I recommend reading it.

I think I found a typo in a Cryptoquip.

Like every good late Baby Boomer, I watched many episodes of the Tee Vee show M*A*S*H. But I hadn’t read the book.

I found a blog post about Millisecond accurate Chrony NTP with a USB GPS for $12 USD.

Wow! I’ve had an interest in NTP since about 1994, when I had to prove that a system my (somewhat shady) employers were selling to an NSA cut-out could synchronize to an NTP server.

I got a Roomba robovac a few months ago, partly because I hate vacuuming, partly because I grew up in the 1960s, when we would have vacations on Mars by 2025, and robot maids and butlers would take care of us.
