Annoy people with a remote-control car horn

Although April the first has passed us by, the following project by Lewis Callaway has both very annoying and very useful aspect. The main purpose is to have a car horn that you can activate from afar via an Internet-connected Raspberry Pi.

By adding a USB webcam to the Pi you can view the unlucky person before giving them the toot of the horn from the relative safety of your remote location - a demonstration of this is shown in the following video:

However this project also offers you the framework for creating a remote-controlled device that could be more useful to you, such a combined CCTV/remote door or garage opener amongst other things.

Nevertheless for complete details, visit the project page. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

For more complex Raspberry PI projects that require interaction between an Arduino and a Raspberry Pi for enhanced hardwre control you can save time and space by using our new PiLeven board:

The PiLeven is an Arduino-compatible board based on the Arduino Uno, but with a few changes. Obviously it's a bit of a strange shape! The PiLeven fits right on top of a Raspberry Pi (either model B or B+) using the Raspberry Pi expansion headers.

The PiLeven also has a high-current switchmode power supply, so you can plug in anything from 7V to 18Vdc using the standard 2.1mm jack. The PiLeven can power the Raspberry Pi, so you don't need a regulated 5V USB connection anymore.

Serial communications on the PiLeven is linked through to the Raspberry Pi, so your Pi can upload new sketches straight to the PiLeven or send/receive data and commands. We've included level shifters so the 3.3V Pi can talk safely to the 5V PiLeven. And you can plug standard Arduino shields right into the PiLeven, giving your Raspberry Pi access to the huge range of shields already available. For more information about the PiLeven, including our tutorials - and to order yours today, visit the PiLeven webpage.
