Ding Dong!
Clive Webster has written a tutorial over on
expertreviews.co.uk which uses online service Pushover to send you an alert on your smartphone when your doorbell is pressed. He’s created the doorbell switch with a nice Adafruit button, hooked it up to the Pi and then played the sound of the doorbell from the Pi. It’s an interesting project. Be aware, though, that Pushover is a paid (albeit cheap) service that only works on iOS and Android.

Keep on Truckin'
vace117 has taken an old remote controlled truck, ripped the innards out, replaced it with a Raspberry Pi and then strapped an Android phone to the top to provide a video feed. (Yes, he could’ve used the Pi camera, but let’s not hold that against him). He’s then used WebRTC as a web interface for controlling the car. You can see a video below and

Slippery Slope
Linux guru Les Pounder has created this fantastic version of Snakes and Ladders called Pythons and Resistors, hooked up to a Raspberry Pi. You press a button to perform a dice roll and magnets and reed switches embedded in the playing pieces and the board trigger sounds to be played if you hit certain squares – the pythons (snakes) and resistors (ladders). It’s a really nice project for which he has provided
a complete build-and-code tutorial.
