SPAN has announced that its four newest smart panel models are the first to receive UL 3141 certification. This safety standard for Power Control Systems ensures devices can manage electrical loads effectively while protecting consumer safety and device integrity. The certification supports increased home electrification by utilizing existing utility infrastructure, potentially helping homeowners avoid expensive service upgrades.
The author demonstrates how to run Espressif's ESP-Claw agent framework on an ESP32-P4 microcontroller using a self-hosted Qwen 3.6 LLM. Unlike standard TinyML implementations that only use microcontrollers for simple tasks, this setup allows the chip to manage sensing, decision-making, and tool execution through Lua scripts triggered via Telegram. The project shows how hardware behavior can be modified in real-time through chat without needing to recompile firmware.
Main topics:
* Implementation of an agent loop directly on a microcontroller
* Using Lua modules for dynamic runtime skill acquisition
* Interfacing with LLMs via OpenAI-compatible APIs
* Controlling peripherals like GPIO, I2C, and sensors through natural language
* Utilizing Telegram as the primary user interface

This article explores the concept of harness engineering, arguing that a functional AI agent is defined not just by its underlying model, but by the scaffolding built around it—including prompts, tools, sandboxes, and feedback loops. The author suggests shifting focus from picking the smartest model to designing robust systems that turn raw models into reliable agents. By treating mistakes as signals for new constraints rather than simple failures, engineers can create a ratchet effect that continuously improves agent performance through better configuration.
Main topics:
- Defining an agent as the combination of a model and its harness
- Reframing model errors as configuration or skill issues
- Using failure history to implement permanent rules via hooks and documentation
- Core primitives including filesystems, bash execution, sandboxes, and memory management
- Managing context rot through compaction and tool offloading
- Achieving long-horizon work through planning, verification, and agent splits

>"A practical comparison between rule-based PDF extraction using pytesseract and an LLM-based approach with Ollama and LLaMA 3, based on a realistic B2B order scenario."
- Regex approach excels with stable, standardized layouts.
- Regex offers speed, low cost, and deterministic results but requires high maintenance as document variety increases.
- LLM approach (using LLaMA 3 via Ollama) leverages semantic context to handle diverse field names and formats automatically.
- LLM approach reduces manual rule updates.
- Trade-offs: LLMs provide superior flexibility for complex layouts but incur higher latency, greater infrastructure costs, and probabilistic uncertainty compared to traditional methods.
- Selection depends on document stability, required throughput, and need for explainability.

This article explores the feasibility of running Large Language Models (LLMs) locally using only a CPU, challenging the assumption that expensive GPUs are strictly necessary. By testing eight different models on an older Intel i5 laptop with 12GB of RAM via Ollama, the author identifies which models offer practical usability for everyday tasks.
Key points include:
- Using tokens per second as a more critical metric for usability than model size or RAM usage alone.
- Why 1B to 2B parameter models provide the best balance of responsiveness and reasoning on low-end hardware.
- The effectiveness of GGUF quantization (specifically Q4_K_M) in reducing resource demands.
- A comparison of various model tiers, from ultra-fast tiny models like Qwen 0.6B to slower, high-capability models like Ministral 3 8B.
