Hackaday ☛ LDU Decoded: The Untold Tale Of LEGO Dimensions
LEGO bricks might look simplistic, but did you know there’s an actual science behind their sizes? Enter LDUs — LEGO Draw Units — the minuscule measurement standard that allows those tiny interlocking pieces to fit together seamlessly. In a recent video [Brick Sculpt] breaks down this fascinating topic.

Mike Rockwell ☛ Framework: Hardware
Continuing my discussion of the Framework laptop that I started earlier this month. Today, I’m going to talk a bit about the notable hardware components of the machine.
As a bit of an aside, this one took me a little longer to finish writing than I originally expected. The Christmas season is always hectic, but for some reason this year felt like it was especially so. I’m still hoping to have the final part of this series published before the end of the year, though, in which I’ll share some final thoughts and touch on how the Framework feels to use.

Guido Günther: Phosh 2024 in Retrospect
As in 2023 I took another look back at what changed in Phosh in 2024 and instead of just updating my notes why not again share it here.
The Phosh developers focus from day one was to make devices running Phosh daily drivable without having to resort to any proprietary OSes as a fallback. So the past years were often dominated by adding essential features to make that possible and reliable at all.

CNX Software ☛ HiFi-Amped is a Raspberry Pi Audio HAT with dual DACs and class-D amplifiers
Sonocotta’s HiFi-Amped is a Raspberry Pi Audio HAT designed for Raspberry Pi single-board computers. It features dual PCM5100 DACs and TPA3110 (2x15W @ 8-Ω or 1x 30-W @ 4-Ω) class D amplifiers for high sound quality and power efficiency. Key features of this module include support for both small and large speakers, an external power source to drive speakers and power the Raspberry Pi, and the ability to shut down the amplifiers using GPIO pins for minimal noise when not in use. This makes it ideal for creating a Raspberry Pi-based media center or audio streaming setup.
