This project is a thrust-vectoring inverted pendulum and it is demonstrating of how one might control an unstable system. It consists of a propeller and motor mounted to a servo on the end of a pendulum.  The servo allows the thrust to be angled or vectored in order to swing-up and balance the pendulum.  Control is accomplished by a PC running LabVIEW, but in the electronics you’ll also find a pair of AVR microcontrollers for PWM signal generation.

This project is a USB IR remote controller for your PC. This receiver is based on PIC18F2455 and is plug and play. It receives, decodes signals from a remote control and emulates the received signals as keystrokes in a keyboard. It is recognized as a USB keyboard. It is compatible with Sony SIRC 20 bit protocol,works with LG and SKY universal remotes when they are configured as Sony DVD. [via]

The Button Code is a system that allows a single button to act as a keypad. The user enters a 4 digit code into the system using button taps. When the correct code is entered a relay is activated. When activated it can either activate for a programmed time or simply toggle the output whenever the correct code is entered.

This project shows how to control your PC remotely. The heart of this project is an Arduino Duemilanove microcontroller, equipped with an Ethernet adapter, and a home-made circuit that connects it to power switch on my computer. The Arduino is always on, so at any time and from anywhere in the world, you can command the Arduino to start up the computer. Check this project’s details on the link below.
