One of the newest and fastest growing additions to the digital age in the 1990s has been the handheld personal computer. Given a little flash memory and a good LCD, anything is possible and commercial products like the 3Com PalmPilotâ and IBM Workpadâ are flourishing. But as these products expand their functionality so does […]

The Tompkins Instrument 3PO is a 32-function scientific calculator. It rivals the competitions with its blazing fast 4-megahertz Atmel 8515 Microcontroller based design. The TI 3PO includes a series of function useful in scientific computations such as trigonometric functions, base conversions, logarithmic functions, logical operators, inequality functions, floor and ceiling, and exponentiation. The main […]

A universal remote is a common everyday household appliance. Used to do everything from TV/Video/Cable to ceiling fan control, this project is a extremely versatile product. We planned to have a 32-button remote that could replicate the IR characteristics of a VCR & TV remote control.
Link: Universal remote, AT8535

As technology develops, computers are making people’s lives progressively easier and safer. Someday they will be able to drive automobiles, resulting in reduced deaths and accidents. We decided to make a prototype of a self controlled car. We started with a Hot Shot II radio control car and stripped out the radio receiver. Then […]

Project description:
Spectrum analyzers are used to output the frequency content of an arbitrary input signal. It was our opinion that such a system could be implemented on a microcontroller, almost fully in software.  Doing this, however, necessitated some knowledge of standard Digital Signal Processing techniques, namely sampling, analog-to-digital conversion and most importantly constructing digital filters. […]

For the final project, we designed a Microcontroller-driven Lego Vehicle (MLV). This project makes use of the ATMEL AT90S8535 8-bit RISC microcontroller unit. The microcontroller basically functions to determine the user input through button pushes, drive the DC and stepper motors to provide motion to the MLV as well as to set the speed […]

Our final project code calls for the implementation of an amusement game often bannered as “Test-Your-Strength” or less accurately (but more commonly) known as “Whack-a-Mole.” Our machine is in essence a miniturized version of what can be found in most theme parks across the world. Its construction involves a spring load plastic cap to […]

For our final project, we set out to write a Controller for the classic toy, the Etch-A-Sketch. What this basically means, is that we use an Atmel micro controller to control two stepper motors connected to the knobs of the Etch-A-Sketch. Thus, an order by the chip to the motors would cause different angled […]
