Any time I show power consumption graphs for the SBCs, computers, and servers I test, I get a number of comments asking for more details about the setup.

It's quite simple, really: using my Home Assistant Yellow 's built-in Zigbee radio, I connect a number of ThirdReality Zigbee Smart Outlets to it, and then I use ApexCharts Cards to add graphs of power consumption over time on my Home Assistant dashboards.

I can then monitor power consumption, accumulate long-term energy use data,

Sipeed's NanoCluster is a tiny compute module clusterboard with room for up to 7 tiny computers.

Each slot has two inline M.2 (NGFF) slots which accept either a custom-designed SoM (System on Module) or an adapter board to adapt a standard Compute Module form-factor board into the slot (as pictured above).

One end has a large fan for cooling, and the other end has power and IO. You can power the board via either PoE++ (60W)

I just received my second community guidelines violation for my video demonstrating the use of LibreELEC on a Raspberry Pi 5, for 4K video playback.

I purposefully avoid demonstrating any of the tools (with a suffix that rhymes with "car") that are popularly used to circumvent purchasing movie, TV, and other media content, or any tools that automatically slurp up YouTube content.

In fact, in my own house, for multiple decades, I've purchased physical media (CDs, DVDs, and more recently,

The most unique Raspberry Pi I own is a limited-time flavor: blue raspberry . And no, this isn't the Brazilian version , or the red Chinese version . This blue version is one of 1000 blue Pis that were made to celebrate Raspberry Pi's first anniversary, 12 years ago.

What's crazy is this original Pi (well technically the 2nd revision of the original Pi...)? It's still supported . Apple usually stops supporting their Macs after

I'm deep in the rabbit hole of all things time and timing. One step on any modern horologist's journey is GPS time.

NIST just put NIST-F4 online , accurate to within 2.2e-16 ppm (that's 0.00000000000000022 seconds. The clock is described in Metrologia thusly:

The fountain uses optical molasses to laser cool a cloud of cesium atoms and launch it vertically in a

I've been deep into time and timing lately (more shenanigans coming tomorrow), but today I posted a video covering the install of a PCTEL GPS/GNSS antenna at my studio.

I put up the antenna after realizing how indoor GPS reception is just never that great, due to a variety of factors (like multipath propagation and interference), even if I placed my antennas up in the plenum space right under the roof. Of course, it doesn't help that my studio has a metal roof :

...with caveats.

TL;DR

• The Radxa Orion O6 is an Arm ITX motherboard with up to 12 cores, 64 GB of RAM, and Armv9.2 support, starting just over $200 USD
• The board has a SystemReady SR-certified BIOS , which allows running Windows on Arm and many Linux arm64 ISOs unaltered
• The firmware still has many quirks, enough that I wouldn't recommend it if you don't enjoy tinkering with drivers (remember how I said

For the past couple years, I have transported my 'working set' of video and project data to and from work on an external Thunderbolt NVMe SSD.

But it's always been slow when I do the sync. In a typical day, I may generate a new project folder with 500-1000 individual files, and dozens of them may be 1-10 GB in size.

The Thunderbolt drive I had was capable of well over 5 GB/sec, and my 10

I've been getting into time , with my most recent project being a DIY PTP Grandmaster Clock with a Raspberry Pi .

For most civilians, the most accurate source of time available comes from satellites—GPS, GLONASS, Galileo, Beidou, etc.—nowadays referred to as GNSS (Global Navigation Satellite System). Originally targeted at GPS only, even cheap dongles today cover multiple constellations adding to the accuracy and coverage of satellite-based positioning and timing signals.

I've done most of
