Playing with a Power Meter
I bought a outlet power meter from Amazon — the kind where you plug-through the device to reach to the actual outlet — and the device measures energy usage. This particular one has the basics: power (kWh), current (A), AC voltage (V, presumably rms), and a couple oddities like power factor and energy cost that…

Comitting Life to Memory
As we grow older, time moves faster because we have fewer novel experiences per unit of time. Also, each day we experience is increasingly less significant to us if we think of each day as equally impactful. It seems inevitable that time moves faster and faster for the rest of our days. Why? The reality…

The Sad State of Consumer IPv6
IPv6 on home routers is in a sorry, sorry state. I got the itch to learn IPv6 networking and started with testing several high-end home routers to see which units might best meet my educational and experimental needs. I figured that once I identified a solid fit, my new (potentially used, but new-to-me) device would…

From SBC to Mini PC
Hardware matters, but software matters so much more. Easy as Pi For years software support, documentation, and the surrounding community of hobbyists made the Raspberry Pi outstandingly popular to the point of techno-culture phenomenon. The Raspberry Pi 5 was released earlier this year, but supply issues continue such that a casual purchase today won’t be…

Not a Car Guy
I drive a red 2018 Kia Soul. It features an inline-four flexible grade gasoline internal combustion engine. The design has recent improvements like variable valve timing and direct injection, but the design is decidedly static compared to more exotic engine designs like small forced induction (turbo charged) and hybrid designs. My living arrangements cannot support…
