Having heard about the new camera driver built into the kernel of the new Raspbian OS image, I decided to have a play, using my PS3 EyeToy camera. The steps below are based on this forum thread, with some changes to reflect my own experience. The Raspberry Pi supports a number of cameras, not just the EyeToy, so if you have a spare one lying around, give it a go.

Install the ‘motion’package:sudo apt-get install motion

This should automatically install the required ‘ffmpeg’ package – if not you can just do sudo apt-get install ffmpeg.

Edit the config file:sudo nano /etc/motion/motion.conf

To enable daemon mode (so you can run the software in the background without it tying up your terminal):daemon on

How to Find ANY Icon

Open the application such that you see the icon on your screen.
Open Activity Monitor
Double click the name of the application (i.e. Finder or System Preferences)
Select "Open Files and Ports"
Copy the output to a file and then grep for .icns

Similarly you could run this command, but it may take several minutes to complete:

	#!/bin/bash

	# Steps to create the macOS Catalina (10.15) VM:
	# login to developer.apple.com or beta.apple.com to download a tester's profile for your OS. Install it.
	# Go to System Preferences > Software Update and start the update process
	# When the Catalina Installer (few MBytes) is started, it downloads the remain part of installation.
	# After all `Install Catalina Beta.app` should lay in the /Applications folder with approx. 6.5g size
	# Proceed with the following script.
