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.

The Electronic Mini-Badge is a PIC24FJ64GA004-based electronic badge that displays color slideshows. Many electronic badges display scrolling text using a matrix of discrete LEDs. This low-power system features a graphical OLED display and can be easily upgraded to handle animation, video, or RF communication.
I’ll have to take a look over this circuit’s schematic to see if i can easily adapt it to a Nokia 6100 LCD display, because i happen to have one, and it would be a nice project.

The handy Butterfly GPS is a cost-effective system that presents location, date, and time data on its LCD. The system features an ATmega169 and a highly sensitive GPS receiver engine board based on the SiRF chipset. Its amazing what you can do with such a low cost development board.

This system automatically switches from one ADSL modem to another every time there is a link failure. The ATmega16 monitors network connectivity over Ethernet. When a failure occurs, it automatically powers off the primary ADSL modem and powers on the secondary ADSL modem.

Were starting to see more and more green designs, which is nice, some people are really concerned about the planet we live in. The PowerBox is part of the Cornell University student projects 2008, and its main goal is to calculate and report the following parameters:
- Real power
- Apparent power
- Power factor
- RMS Voltage
- RMS Current
- Frequency
- Energy usage (Kilowatt-Hours)
All of the data is gathered by a C application which shows real time graphs and data display. Another feature of the PowerBox is that it features a remote switch that allows the computer to turn the power on or off and set wattage limits for auto shutdown. This way people can monitor and control their energy usage. Good job Cornell students.
