Live stream to http://twitch.tv/adafruit giving a quick look at Tor hidden services on the Raspberry Pi. This technology allows you to securely expose services on a Raspberry Pi (like camera streams, home automation, or even your own DIY services) to the broader internet over Tor's network. This video looks at how to expose a mjpeg-streamer Raspberry Pi camera stream over Tor with a hidden service.

Live stream to http://twitch.tv/adafruit showing part 4 in the Raspberry Pi Cat Laser 2.0 series. This part looks at how to build a cloud server with Python, flask, and flask-socketio which allows multiple people to control the cat laser. Instead of each user trying to individually access the Pi they instead access the cloud server (running a virtual machine for now) and it sends control messages to the Pi (using MQTT) and serves up the Pi's video stream. Adding the cloud server allows many more users to control the laser vs. if they tried to access the Pi directly and overloaded it's meager CPU.

Live stream to http://twitch.tv/adafruit showing part 2 in the Raspberry Pi Cat Laser Toy 2.0 project. This video revisits the code for the original cat laser toy project and gets it running again with the hardware for the updated 2.0 project. Will the cat play with the laser? Watch the video to find out!

Note there's some choppiness in the main shot at the end--sorry it's some issue with Wirecast that will hopefully be worked out for future videos.
