SBC Case Builder v3.0 can create thousands of cases for popular SBCs and standard motherboards (mini-ITX, Pico-ITX, NUC…)

SBC Case Builder V3.0 case design utility has just been released with the ability to create over 1,000 standard cases – not including customization – for popular SBCs from Raspberry Pi, Hardkernel, Orange Pi, Radxa, and others, as well as standard motherboards following Mini-ITX, Pico-ITX, NUC, Nano-ITX, etc.., and SBC adapters following these standards, meaning you could install a Raspberry Pi 5 into a mini-ITX case if needed. … Once you have generated a case design, you can use the resulting OpenSCAD file with a 3D printer or CNC machine to build the enclosure.

How to connect to Raspberry Pi Desktop using wayvnc VNC Server

The following description is from a (slightly edited) Mastodon post:

When I prepared a Raspberry Pi with the latest Raspberry Pi OS (based on Debian Bookworm) as a monitoring and observability display, I noticed the “wayvnc” package during the dist-upgrade.

Turns out this is a pre-installed VNC server package – at least on the Desktop variant.

But how can the VNC Server be configured and started and more importantly, how can I connect using a VNC viewer? Figured it out and wrote about it

Reducing Raspberry Pi 5’s power consumption by 140x

Sorry to clickbait with that title… but it’s actually true. I can help you improve power use by 140x—for power off power consumption, at least.

By default, the Raspberry Pi 5 (like the Pi 4 before it) leaves the SoC powered up (just in a shutdown state) when you shut down the Pi.

Because of this, a Pi 5 will still sit there consuming 1.2-1.6W when completely shut down, even without anything plugged in except power.

GPS Raspberry Pi NTP Server

This post details how to create a stratum-1 NTP Server using a Raspberry Pi utilizing GPS and PPS, and get time within 100 nanoseconds of real time, directly from the atomic clocks located in the GPS satellites above your head. The best part about this guide is that this will work with no internet. After initial setup, you could disconnect it from the internet and they would work. All of the other guides out there that I have found do not include the configuration necessary for this.

Quickly resize and shrink Raspberry Pi SD card image on MacOS

From time to time you may want to quickly copy a raspberry pi image from one system to another….but only have a smaller SD card. Or you started your project as a tryout on a crazy 64GB sd card, and realize later that 8GB would be way enough. So what you want to do, is resize the source image to the smallest size possible, flash it to the new smaller SD card, and expand it again to its new maximum on the new SD card. And so far that process can be very long and painful….but luckily there is a very handy script for that, called PiShrink. I am using the mac version, but there is also a linux version.
