This project scans a 180 degree area from about 6 to 21 inches (15cm to 53cm) away and displays the information on a color LCD. To do this is uses. An infrared distance sensor from Sharp and an ultrasonic sensor from MaxBotix. This project is a short range, infrared and ultrasonic scanner that uses a standard hobby servo to move the sensors and a color LCD screen to display the information from the sensors. The information displayed on the LCD is an overhead view of the scanning area, with increments of distance from the sensors.

A master-controller board and three stepper motor driver boards drive this well-designed PCB drill machine. There are four single-sided boards each featuring an ATmega16/32 microcontroller. The master controller initiates and controls all communication. The result ? you drill your PCB’s precisely at the right spot.

With this ATmega32 based system, you can monitor a Fiat’s engine control unit (ECU) as you drive. You can display up to four of the available ECU parameters and have the values updated in real-time as you drive. It also decodes the internal ECU error codes as they occur and displays them in real time. An ECU is the Electronics Control Unit of a car that controls various things like the ignition time and valve timing.

This Atmega32 based WOL Server allows WOL packets to be sent over the internet to a target computer. WOL basically is a system that allows sending of a special type of packet to a computer to power it on (to wake it). Read more about WOL on Wikipedia. The system is password protected so you wont have any security issues.

This circuit is a church bell controller. If you’re not familiar with the idea, it basically sounds a bunch of bells after different melodies and the effect is pretty neat. The controlling is done by an ATmega32 microcontroller hooked up with a 24LC32 memory. For controlling the author implemented a 4×20 LCD and 6 buttons at the face of the circuit’s box (Menu, Up, Down, Enter, Start, Stop). Among the features are :
- More 75 different melodies (ADAM, PANYGJRJKO, AGJORJKO, etc)
- Percussion of clock each half but also entire hours, with possibility of choice of hours of silence (for tourist regions and hours of common quietness).
- When it runs a rhythm you have the possibility of increase or decrease its speed, the information will stored in memory 24LC32.
- Control up to 5 bells and 1 clock.
I must say this is the first project of its kind id seen.
