- 7Hacker News·8/10/2026model_releaseNeedle 2: a 14MB agentic LLM for edge devices
Cactus released Needle 2, a compact 14MB agentic LLM designed for tool use, structured extraction, and device control on phones, wearables, smart home devices, microcontrollers, and small robots. The model uses 45M parameters at 2-bit compression, claims very high token throughput on edge hardware, and can be fine-tuned locally with a Python package and automated data generation pipeline.
- 5Hacker News·8/2/2026open_sourceRISC OS Open marks 20 years of open development
RISC OS Open reflects on two decades since its 2006 founding, when it began opening up the proprietary RISC OS codebase to community participation. The post highlights major milestones including public source releases, stable RISC OS 5 updates, Raspberry Pi support, the Apache 2.0 relicensing, and the move to broader open collaboration.
- 5Hacker News·7/30/2026product_launchgpiozero flow UI turns GPIO device logic into visual streams
The author describes the evolution of gpiozero, a Python library for Raspberry Pi that models GPIO control around devices and value streams instead of raw pins. A new web-based simulator and visual editor now lets users drag devices onto a canvas, connect them with flows, and generate equivalent Python code, with plans to extend it toward remote Pi GPIO control.
- 4Hacker News·7/28/2026product_launchReFrame: an open-source ePaper camera
ReFrame is an experimental camera that uses a color ePaper display to show one photo at a time, with each image taking about 15 seconds to fully render. The project is open source and built from off-the-shelf parts, including a Raspberry Pi Zero, Pi Camera 3, and a 4-inch E Ink Spectra 6 display.
- 6Hacker News·7/19/2026open_sourceHN: Open-source bowling alley control system built with ESP32s
A bowling alley owner describes replacing a proprietary lane-scoring and control setup costing tens of thousands of dollars with a custom system built from ESP32 microcontrollers. The prototype uses ESPNow, RS485 fallback, a Raspberry Pi lane computer, and Redis to handle sensor events, relay control, and UI updates, with plans to open source the hardware, firmware, and software stack.
- 3Hacker News·7/19/2026open_sourceRebuilding a Raspberry Pi home server after microSD failure
The author describes a Raspberry Pi 4B home server that became unbootable after a likely failed microSD card, worsened by a recent power outage. They rebuilt the setup with a focus on reducing writes to the SD card, adding backups and redundancy, and moving volatile data to RAM-based storage and zram swap under NixOS.

QuadRF is a phased-array radio system built around a Raspberry Pi 5 and an FPGA board, designed for advanced RF signal processing, beamforming, and visualization. In testing, it could detect drones in flight and identify Wi‑Fi signals through walls in the 4.9-6 GHz range, while also serving as a platform for SDR analysis and radio experimentation.
