@ Requires msysGit (obviously), which can be installed either from their website or through choco.
@ Put this file somewhere in your %PATH%, like C:\Windows\System32 (if you put it there, you'll also want it in C:\Windows\SysWOW64).

Open and close an animatronic mouth on a Raspberry Pi GPIO pin
#!/usr/bin/env python
This script animates a motorized mouth on a Raspberry Pi GPIO pin so that it
appears to be speaking alongside the audio on the specified PulseAudio source
(which usually should be a sink's monitor).
Find PA_SOURCE with `pactl list` and look for a monitor device that corresponds

OpenCV sample stereo camera usage
import numpy as np
import cv2
# Set up specifically for the ELP 1.0 Megapixel Dual Lens Usb Camera Module ...
# This camera enumerates as two separate cameras, hence the separate `left` and
# `right` VideoCapture instances. For a proper stereo camera with a common
# clock, use one VideoCapture instance and pass in whether you want the 0th or
# 1st camera in retrieve().

This is a set of scripts that calibrates and calculates a depth map from a stereo camera. It is primarily written with this ELP stereo camera in mind, but it theoretically should work with other hardware.

See for a full writeup.
