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:

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)
 
TPicShow is an image slider VCL that enables you to create amazing splash screens and 176 transitional effects in pure Delphi code.
 
Features:
  1. Image transition can be controlled programmatically
  2. Image can be stretched or centered in the client area of the control
  3. Control can show a background image as centered, stretched, or tiled
  4. Transition process can use a separate thread
  5. New transitional effects can be easily implemented and added.
 
TPicShow's last update is on July 19, 2010 which does not support RAD Studio XE. By creating a package file, you can installing and running TPicShow on RAD Studio XE5 without any problem.
