Ultrasonic Spotlight Tracker

July 29, 2008 by Chris
This is a simple little project that shows how powerful automation can be. It uses ultrasonic sensors and a microcontroller to keep a spot light pointed at the object moving infront of the sensors. The project write-up has both detailed hardware schematics & the software.

Nintendo Mouse

July 2, 2008 by Chris
The standard NES controller has been made into mp3 players, walkmans & plenty of other random yet incognito devices. This time it has been made into a fully fledged computer mouse. Check out the project write-up to see how it's made.

Homemade Wind Vane

May 31, 2008 by Chris
The homemade weather vane is a simple project with a compass display to show you which way the wind is currently blowing. The purpose of course is for logging weather (wind) data over long periods of time. The write-up lists all necessary parts & the construction procedure.

Multifunction In-Dorm Automation System (MIDAS)

May 30, 2008 by Chris
This system has many different devices interfaced together all controlled by a central computer & program with a straight forward gui. The idea is to spice up this guys dorm room. He's made a decent write-up with pictures and videos, take a look.

Embedded Linux Sprinkler Controller

May 22, 2008 by Chris
This is a 4-zone sprinkler controller using embedded linux. It was also modified to control a garden hose sprinkler system. The implementation is fairly innovative, plus there's lots of pictures, schematics & lists everything you'd need to build it.

IR Remote Control

May 14, 2008 by Chris
Today's project write-up is an IR Transmitter/Receiver pair using a PIC microcontroller. The circuit for both the transmitter and receivers is fairly complicated however not impossible to build. All the information you'll need to make them can be found in the write-up.

Infra-Red Proximity Sensor

May 8, 2008 by Chris
IR sensors are usually housed in some nice casing to get optimal performance and it will be on a PCB with a standard output connector. Rarely do we see how these things actually work. This project write-up shows how a basic IR range sensor works using 2 LEDs (IR Transmitter/Receiver).

Low Frequency AVR Oscilloscope

May 5, 2008 by Chris
Digital Oscilloscopes made with microcontrollers are always both cool little gizmos and very useful. This AVR based oscilloscope is limited in features, however its small size and low build-cost make it worthwhile. Hardware schematics and software are available for download.
