Description
I am a HAL9000 computer. I became operational at the desk of Jürgen in Köln, Germany on some unknown day in 2022.
This HAL9000 is designed to house a Raspberry Pi Zero2 (much better performance than the original Zero) and a Seeed Respeaker 2-Mic HAT as well as a microcontroller with a display (currently either a M5Stack Core2 or a RoundyPi). Other hardware components are optional:
At the core, this HAL9000 is designed/constructed to be a voice assistant. Because all computation (wake-word detection, speech-to-text conversion, command execution and text-to-speech generation) is done on the Raspberry (thus the Pi Zero2), it is entirely offline-capable (no cloud) and therefore very privacy-oriented.
The hardware (3D printed parts and the selection of electronic components) are the result of a multi-year development process (albeit with long breaks in between); I consider the hardware to be finalized (but I am open for suggestions, create an issue or PR on github). The software (voice assistant and the integration of the physical user-interface components) are still somewhat work in progress, but are fully functional (think proof-of-concept).
For (voice assistant) software with proper integration and OpenSCAD source files, please visit the GitHub repository: https://github.com/juergenpabel/HAL9000/
The software can be comfortably installed using the installer (pre-build binaries exist for arm64 and amd64): https://github.com/juergenpabel/HAL9000-installer
Everything pictured has been printed on a Qidi X-Maker with a 0.5mm nozzle using 3DK.berlin PLA Aluminium Silber Metallic (I've tested many different filaments over the years and this one seems to be the best match) and some rather random black filament. Please take a look at the BOM.
