Tiny microcontroller chips, traditionally limited to simple embedded tasks, can now run a diffusion model for image generation and a compact 289-million-parameter large language model. The news, highlighted by Adafruit and Open Source For You, points to rapid progress in on-device AI, letting small, low-power hardware perform generative tasks without cloud servers. Enthusiasts are discussing what this means for smart devices, robotics and offline AI applications.
- 3Meshtastic Buyer's Guide Compares Solar Node and Mesh Tracker▼Meshtastic Hardware Buyer’s Guide: Solar Node vs Mesh Tracker — Which One Do You Need?
Adafruit has published a buyer's guide for Meshtastic hardware, comparing solar-powered nodes with mesh trackers to help users decide which device suits their needs. The guide walks through the trade-offs between the two off-grid communication options. Interest in Meshtastic, an open-source long-range radio mesh network, continues to grow among hikers, hobbyists and people preparing for situations without cell coverage.
