Wireless Programmable Pace Clock

A Wireless Programmable Pace Clock Using Atmega644

For our ECE 4760 final project, we designed and built a wirelessly programmable digital pace clock with a large format LED display and Android smartphone control and programming. This original design achieves the functionality of commercailly available pace clocks but with an intuitive user interface that goes beyond anything that is available in the current marketplace, all at a small fraction of the cost. The clock …

Lock in Amplifier and Temperature Control

DNA Melting Part 2: Lock-in Amplifier and Temperature Control Using Arduino

In Part 2 of the DNA Melting Lab you will make revisions to allow greater control of your instrument and to reduce the effects of noise. You will add a pulse-width modulation (PWM) heater controller to enable careful control of the heating and cooling rates of the DNA sample. This will allow you to maintain …

Arduino Solar Shield

Arduino Solar Shield – A DIY solar source for your projects without waiting for PCBs

This instructable is a basic version of Bley Joel’s (“It’s nine o’clock on a Saturday, the regular crowd shuffles in”) Solar Shield, and it should work for most arduinos.  I’ve tested it with SparkFun’s Arduino Pro, and the new Leonardo. Myself and the other Solar Pocketeers* are actually waiting for a new set of PCBs for …
