PiShrink is a bash script designed to automatically shrink Raspberry Pi images, making them easier to store and faster to flash onto SD cards. Once the shrunk image is booted, it will automatically resize itself to match the maximum capacity of the target SD card. The tool also supports compression using gzip and xz, with an option for parallel compression across multiple CPU cores to improve speed.
Key points:
- Automatic shrinking of Raspberry Pi images
- Boot-time filesystem expansion to full SD card size
- Support for parallel multi-core compression
- Compatibility with Linux, Windows (via WSL 2), and macOS (via Docker)

This project details how to serve offline content (Wikipedia, etc.) from an ESP32 microcontroller, specifically using a LILYGO T-Dongle-S3. It covers the process from downloading ZIM files, processing them with Python scripts, transferring to an SD card, and loading a sketch onto the microcontroller to serve the content via a WiFi access point.
Michael Wessel has released the PicoRAM Ultimate Rev. 2, a memory and storage emulator for vintage computing systems, increasing RAM emulation to 4kB. It supports various systems like the 6502, MC6400, Micro-Professor, and Heathkit, offering SD card storage and ROM emulation.
A user has generated higher zoom level map tiles for Meshtastic 2.6, based on OpenStreetMap data, and is sharing download links for various regions (World, Europe, USA, Canada, South America, Oceania). They also suggest formatting the SD card with a small block size (8K with FAT32) for optimal performance.
