What it does

This repo holds the Python API, sample code, and SD card images for Google’s AIY Projects—cardboard kits that let you bolt a Vision Bonnet or Voice HAT onto a Raspberry Pi. The aiyprojects branch covers both kits; older branches preserve the original Voice-only code and a deprecated “Voice Recognizer” demo.

The interesting bit

Google essentially productized the maker experience: pre-trained vision models and Assistant integration, wrapped in a Python API tidy enough that hobbyists didn’t need to wrestle TensorFlow directly. The project is now in maintenance mode—last meaningful activity appears to be around 2017–2018—making this a fossil record of Google’s brief hardware flirtation with the maker crowd.

Key highlights

• Pre-built SD card images with all dependencies baked in (aiyprojects-2017-12-18.img onward)
• Separate branches for kit-specific and legacy code
• ReadTheDocs-hosted Python API reference
• Example code in src/examples for common vision/voice tasks
• DIY image building possible via the separate aiyprojects-raspbian-tools repo

Caveats

• The master branch contains a deprecated demo; the README itself warns you away from it
• No clear indication of ongoing development or support lifespan
• Hardware kits themselves are discontinued and increasingly hard to source

Verdict

Worth a look if you already own the hardware or want to study how Google packaged ML for novices. Skip it if you’re starting fresh—modern Raspberry Pi AI options (like the Coral USB accelerator with current software) have left this behind.
