I own a TP-Link TL-WR1043 V2.1 wireless router, I would like to test if it is able to run on OpenWRT or DD-WRT. it is first tested on OpenWRT, DD-WRT later, so far it has been working flawlessly for me.

This is a guide on how to setting up a simple wireless hotspot using a TP-Link TL-MR3020 3G/4G Wireless N Router installaing with NoDogSplash. The goal is to provide a free hotspot with a splash page to advertise who is providing the hotspot, it should work as well for other OpenWRT supported router.

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).
Midori is a lightweight browser using the WebKit rendering engine and it is a default browser that is found in Raspbian. This is a quick quide to start the Midori browser from the command line without a desktop manager.
 
To start the Midori in full screen mode, use the following command:
xinit /usr/bin/midori -e Fullscreen -a http://domain/homepage.html
However it is not in full screen mode, it just fill up about quarter size of the screen. To fix this problem, Midori must run on a windows manager. Here is the solution:
