My 1984 Desk

I try not to spend much time talking about ye olde timey computing that I lived through, because it quickly becomes boring to all but those who were there, and the future is so much more exciting. But in looking up evidence I had of Tektronix having Ethernet (and Internet connectivity before that), I found a photo of my olde timey Tektronix office desk, and couldn’t resist cataloging how office computing has changed.

Cost-Reducing the Lunar Clock: IoT really is here

I have to confess that sometimes I need a push to make the right design choice.

It’s been a long time – way too long – since I worked on my Lunar Clock project. In the meantime, Sparkfun has introduced new, inexpensive microcontrollers aimed at Internet-of-Things applications. I knew one of those new microcontrollers would be perfect for the Lunar Clock, but I dragged my feet.

Chinchilla Cam: Installing the Raspberry Pi Camera Module and OpenCV

For some time we’ve caught rare glimpses of small, rabbit-like animals who seem to be living under our front porch. We’ve seen little, round ears bobbing past the window, footprints in the snow, and during one hot summer I found a dead chinchilla in the garage – the poor thing couldn’t take the heat.

Dog Water Bowl Scale, Part 3: Final assembly and installation

In my previous post, I covered the mechanical construction of the scale. In this post, I finish assembling the scale, calibrating it, and installing it.

After painting I put feet on the scale so it won’t soak in water spilled on the floor.

…then bolted the Arduino 101, Load Cell, and Load Cell Amplifier to the bottom plate. Continue reading Dog Water Bowl Scale, Part 3: Final assembly and installation
