Raspberry Pi Digital Signage
Raspberry Pi (Model B) is a single-board computer that uses an ARM 11 (ARM1176JZF-S core) processor running at 700MHz (it can overclock up to 1GHz) with 512MB RAM.
This article shows you how to turn your Raspberry Pi into a cheap, browser based digital signage solution. It covers setting up a mini webserver on using the lighttpd+PHP web server and also how to start a web browser without a desktop environment.
I will use Midori as the web browser since it is a default browser that is found in Raspbian (a free operating system based on Debian optimized for the Raspberry Pi).

To start the Midori in full screen mode, use the following command:
xinit /usr/bin/midori -e Fullscreen -a http://domain/homepage.html

Wireless Router Remote Control Car
This is my first RC car control by an Arduino and a wirless router running OpenWRT. There are many OpenWRT supported routers, I'm using a TP-Link TL-MR3020 3G/4G Wireless N Router for this project since it is very slim, low power consumption and it is cheap.
RC car features
- A webcam, the car can be driven without line of sight
- A horn so that you can honk at people.
- LED Headlights attached to the front of the car
- Two wheel drive motor
- Windows GUI application or web interface
- Future Additions: Control by a smartphone (Android & IOS)
