Raspberry Pi controlling small LED array. Here is using a LED strip, but the chip may be the same to move the wished module:

Example in Python of a TTS server for Catalan ONNX models

More into the side of how to ensure that the Raspberry Pi 5 behaves correctly having an Ollama service running. Memory, CPU, Temperature... very interesting to have control over the hardware behaviour, to peek on what's important to control.

Piper is a fantastic tool for providing very realistic sounding TTS while also being efficient and fast. There are some publicly available pre-trained models, but if you’re here, that means you want to create your own voice. This guide aims to walk you through the steps.

This GPIO Pinout is an interactive reference to the Raspberry Pi GPIO pins, and a guide to the Raspberry Pi's GPIO interfaces. Pinout also includes hundreds of pinouts for Raspberry Pi add-on boards, HATs and pHATs.

Ollama Model for Catalan

The tool/function calling equivalent for Ollama, looking quite similar to Gemini

The offline Model library for Python

A Python class that encapsulates a Selenium-based web scrapper that outcomes a list of products and its prices from a given department URL.

Similar to the previous link, but apparently there is a new way to do so in the newer 2.x versions that simplifies all internally.
