Since the Raspberry Pi was introduced, hundreds of clones have adopted the Pi's form factor (from the diminutive Zero to the 'full size' model B). Often they have better hardware specs, and yet they remain a more obscure also-ran in that generation of Single Board Computer (SBC). So when I saw Radxa's CM3 and Pine64's…
The Minisforum MS-R1 uses the same Cix CD8180 Arm SoC as the Orion O6 I reviewed earlier this year. But everything else about this thing is different. What this thing should be, is a box that runs Linux and can compete with at least an Apple M1 Mac mini, or a mid-range Mini PC. But what we got... is something…
tl;dr: I set up an open source Time Pi project to build a stratum 1 PTP and NTP timeserver using a Raspberry Pi. Time is important to modern society, and most of us have a clock on our wrist that's more accurate than at any time in human history. But highly precise time is important in many industries, especially…
tl;dr: Use an old-fashioned USB 2.0 flash drive, format it FAT32, download the firmware, make sure it's named correctly, and use the motherboard's 'BIOS Flashback' option after powering off the computer. This past week, I devoted far too much time to the task of updating my brand new motherboard's BIOS. It started…
Today I'm announcing Project MINI RACK, an open source project to help those building homelabs, RF/wireless rigs, and other electronics projects into mini 10" racks. Not everyone can afford (either due to budget or space constraints) to have a full 19" rack in their home. Besides that, people may want to deploy small…
This is the BliKVM PCIe, a full computer on a PCI Express card. This is an IP KVM (Internet Protocol Keyboard-Video-Mouse) that can be put inside another computer or server. Most server motherboards already have remote 'lights-out' management functionality built in. Most frequently this is referred to as IPMI…
Silicon lottery. Now that the Raspberry Pi 5s been readily available (at least in most regions) for a few months, more people started messing with clocks, trying to get the most speed possible out of their Pi 5s. Unlike the Pi 4, the Pi 5 is typically comfortable at 2.6 or even 2.8 GHz, and some Pi 5s can hit 3.0 GHz…
