HAL 9000 (v2)

thingiverse

This is an update to v1 of my HAL 9000: https://www.thingiverse.com/thing:2774212 Major changes: - includes a TFT display, [glowing like HAL in the movie when interacting with mycroft](https://streamable.com/xvl5tx) (integrated into mycroft accordingly); the TFT display is attached via an USB connected FT232h - front side grill is not printed anymore; a wire mesh is used for much improved acoustics (the two microphones are located behind that wire mesh) Minor changes: - (optionally) using two mini turnbuckles on the backside for holding the two case parts together - (optionally) using a large size heat-shrink tube to wrap the ReSpeaker in order to better conceal it behind the mesh (see picture #1 vs. #2) - various minor optimizations in both case halves BOM: - Raspberry Pi 4 (highly recommended over 3B) - [ReSpeaker 2-Mics Pi HAT](https://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT/) - IDC/40pin extender cable 20-30cm - USB A-C corner adapter or USB A-C cable with parallel to cable A connector (there is not much space between the pi4 USB sockets and the display) - [USB FT232H with SPI support](https://www.adafruit.com/product/2264) - [Waveshare 240x240 1.28" round display](https://www.waveshare.com/1.28inch-lcd-module.htm) - Black acryl faceplate 185x90x3mm (hal9000-faceplate) - [1.8" fisheye dome](https://www.amazon.de/gp/product/B01376G9IK) - this one was unexpectedly hard to find; other sizes are possible but you'd have to adapt the mounting rig and the acryl faceplace - [Visaton K20.40](https://www.visaton.de/en/products/drivers/miniature-speakers/k-2040-8-ohm) - optional: [M2 turnbuckle](https://www.fechtner-modellbau.de/zubehoer/ladungs-sicherung/spann-schloesser/14468/spannschloss-m2-alu-mit-gegenlaeufige-gewinde.-gesamtlaeng) - optional: black 50mm diameter heat-shrink tube for enclosing the ReSpeaker as a visual improvement to better hide the Respeaker behind the mesh
