Things used in this project

Hardware components

small through-hole protoboard or small breadboard
You can always cut down a protoboard to suit the needs. Basically you'll use this to create a power splitter to provide 5v power to all the parts via a 1 to 3 split.
×1
USB Adapter, Right-Angle
USB Adapter, Right-Angle
You may want to get a 4-pack from Amazon so you have left and right angle to ensure you have the right part.
×1
5v 4a power adapter
If you use a higher voltage adapter you'll need to add a 5v step-down regulator. There are mounting holes for a https://www.pololu.com/product/4091 regulator.
×1
Adafruit Adafuit CRICKIT for Raspberry PI
The CRICKIT should work on any SBC with a Pi-compatible GPIO. As an alternative, you can use a serial or I2C PWM/Servo controller instead. There are mounting holes for an Adafruit 16 channel PWM Servo controller.
×1
Adafruit Mono 2.5a audio amp
While the Crickit has a built in 3a amp that you can leverage instead, it can be difficult to make it work. So this is an alternative that you can use, mounting points are in the build.
×1
SG90 Micro-servo motor
SG90 Micro-servo motor
Note, you can also use the Feetech FS90 if there are none at Adafruit, there are a lot of TowerPro SG90 knock offs of variable quality. You can find the FS90 at https://www.pololu.com/product/2818.
×2
Flat ribbon HDMI cable with HDMI or Micro HDMI headers
These are basically HDMI ribbon cables made for drone cameras. If you're using an SBC with microHDMI output you'll want to look for HDMI ribbon cable sets that include those and regular HDMI terminals instead.
×1
Raspberry Pi 3 Model B
Raspberry Pi 3 Model B
Hey, these are impossible to come by, so you should also be able to get another brand SBC with a RasPi pinout/mounting pattern like the Libre LePotato, Libre Renegade, or RockPi. Just make sure the USB ports are positioned like the RasPi 3B or the right angle USB adapter won't work and you'll need to figure out how to make a USB extension cable work instead. :(
×1
Speaker with a 1.75 inch mounting hole pattern
This build used a salvaged speaker from an Alexa Echo Dot. So you'll want to find something with a similar hole pattern.
×1
Elecrow 5 inch HDMI display
Basically any 5 inch HDMI display with the HDMI and Power at the top of the display.
×1
Fishing line
Any strong thread with minimal stretch. I use 100 test pound braided line.
×1
female barrel jack
×1
M2, M2.5 and M3 Screws, nuts, and heatset nuts
I used a variety of M2, M2.5, and M3 screws, nuts, heatset nuts, square nuts, and standoffs in this build.
×1

Software apps and online services

Raspbian
Raspberry Pi Raspbian
You can use Debian or a Debian distro like Raspbian, whatever your SBC of choice uses. However, speech services on Ubuntu requires OpenSSLv1, which isn't supported on Ubuntu anymore.
OpenAI api python library
Microsoft Azure Speech Services

Hand tools and fabrication machines

Offline Wake Word training table

This is the wake word table for the "Hey Cippy" wake word, download this to the same location where you put the sample python code if you want to use the Hey Clippy wake word.

Code

Clippy sample python code

Python
Copy this to your SBC then edit to:
1. line 59 - replace x's with your Azure Speech Key
2. line 60 - replace x's with your Azure Speech Region
3. line 61 - replace x's with your OpenAI API key
NOTE: You will probably want to adjust the servomotor angles for your servos wherever you see "crickit_servo"
