HAL9000 voice assistant

3D printed HAL9000 enclosure with a round TFT display (as HAL's eye); with OSS voice assistant kalliope based on Pi Zero 2

Similar projects worth following
This project consists of multiple parts:
1. 3D design of HAL enclosure (openscad) =>
2. Various improvements made to open-source voice assistant kalliope (and some plugins) =>
3. Software to integrate interaction with voice assistant kalliope and HAL's eye (TFT display) =>
4. Documentation (github repo at some point in the future)

Parts 3 and 4 are still work-in-progress.

The basic build just features voice interaction; optionally, the following can be configured for the top side of the enclosure:
- RFID reader (RC522 mini)
- 2x Rotary encoders
- Analog based 4x buttons
The 3D designs for these "features" are already completed; the software is WIP.
