Raspberry Pi Stratum 1 PTP & NTP Timeserver: The Time Pi Project

2025-03-28

An open-source project, Time Pi, builds a stratum 1 Precision Time Protocol (PTP) and Network Time Protocol (NTP) timeserver using a Raspberry Pi 5. Leveraging the TimeHAT add-on board with an Intel i226 2.5Gbps NIC and supporting hardware timestamping, Time Pi achieves high-precision time synchronization, further enhanced by an optional M.2 GPS module. While encountering driver issues with the Intel i226 NIC, the project successfully utilizes Ansible to configure Chrony, NTP, and PTP software, running stably for months. Future plans include outdoor GPS antenna installation, cross-device PTP synchronization testing, and collaboration with Masterclock for advanced time synchronization solutions.

My Bosch Dishwasher Demands a Cloud Connection: A Lament

2025-03-24

The author bought a Bosch 500 series dishwasher, praising its easy installation. However, key features like delayed start and eco mode require a Home Connect app and Wi-Fi connection. This sparked a reflection on manufacturers' over-reliance on cloud control, potentially contributing to planned obsolescence and data harvesting. The author argues that appliances should prioritize local control, with cloud features as add-ons, not replacements for core functionality. This creates unnecessary obstacles and dependence on internet access for basic operations.

Radxa Orion O6: Ambitious Open-Source Arm V9 Motherboard, But Needs Refinement

2025-02-04

Radxa's Orion O6 motherboard boasts being the world's first open-source Arm V9 motherboard, promising high performance, low power consumption, and enhanced security. However, real-world testing reveals performance doesn't quite match the marketing hype of rivalling Apple's M1 chip. While outperforming some competitors in certain benchmarks, results are mixed elsewhere. Furthermore, the open-source hardware claim is questionable, with full schematics and OSHWA certification currently absent. Software-wise, the pre-installed OS presents issues like a default device tree configuration and unusual CPU core load distribution. In short, the hardware shows promise, but software and driver support require significant improvement. Proceed with caution and temper expectations.

Project Mini Rack: Compact, Portable Homelabs

2025-01-17

Jeff Geerling announces Project MINI RACK, an open-source project for building compact 10" homelabs. The project provides resources for hardware and software, showcasing three example mini-racks: a battery-backed solar-powered rack, a low-cost Raspberry Pi cluster, and a high-performance compute-dense rack. A build showcase encourages community contributions and sharing of designs. This addresses the need for smaller, more portable homelab solutions.

Who Needs a $120 Raspberry Pi 5?

2025-01-09

The Raspberry Pi 5 with 16GB of RAM, priced at $120, raises the question: who would buy it? While a compelling option for some, the author argues that the 2GB or 4GB versions offer better value for most users. However, the 16GB model shines for demanding applications like large language models and running multiple VMs or containers. Performance gains are also noted thanks to the new chip revision and SDRAM tuning. Ultimately, the 16GB Pi 5 targets users needing high memory and performance for specific tasks.

Raspberry Pi 500 Modder Successfully Adds M.2 Slot

2024-12-15

A Raspberry Pi enthusiast successfully added an M.2 slot to the Raspberry Pi 500! While the Pi 500 has the header, the slot itself is absent, leading to some controversy. The modder soldered on four tiny capacitors and used a bench power supply to power a bottom pad, enabling the use of NVMe SSDs and other PCIe devices. This modification requires excellent SMD soldering skills and has sparked discussion about the Pi 500's design choices; speculation includes reserving the feature for a future premium model.
