A Differential Scanning Calorimeter

Commercial differential scanning calorimeters used to measure enthalpy are often too expensive for colleges and universities. Although this project doesn't provide the extremely high performance of the commercial devices, it is a remarkably low-cost alternative that is more than sufficient for classroom use. The goals of the project were to create an instrument that has a wide enough temperature range to demonstrate measurement, a fairly accurate temperature resolution, and decent accuracy in measuring enthalpy energy. Most importantly, it had to be rugged to withstand use in the lab. An ATmega8 microcontroller handles temperature control and measurement functions. A PC serves as the user interface and display. This project made by Brian Millier got Honorable Mention in AVR 2004 DESIGN CONTEST.

Web-based AVR Interface using AT90S8535

Project description:
In the vein of today’s trends to embed networking cababilities into simple appliances, our project implements a webpage interface for the Atmel AVR microcontroller. One of the original motivations of this project was to develop a low-level network interface for the Atmel device, specifically by controlling an ISA network card to transmit UDP packets across the Internet. We greatly modified our original plans once we found out about the SitePlayer device.

The Autonomous Tank using AT90S8515

Project description:
Here is ,another cool project from course ee476 Cornell university, autonomous vehicle, “Homer”, which can stroll around an environment without getting stuck at obstacles. That implies that it need a robust algorithm that tells the vehicle how to steer when it gets into different obstacle situations. The goal would be to demonstrate a vehicle that will run by itself and not get stuck or bump into any obstructions.
