Our final project for ECE 4760 provides a simple but effective exercise monitoring system of the user’s walk or run. With an increase of the number of health conscious individuals hoping to remain fit, we designed a system that allows the user to keep track of his or her total number steps, current speed, and

Getting Started The goal of this project was to create filters and controls to that can manipulate sound that is being generated through an Arduino. Normally Arduino can only generate simple tones that are not useful if you are trying to achieve complex sounds and do sound manipulation. In order to do this project Mozzi

Introduction We designed a system for wirelessly controlling relays and monitoring current. This is used for a home load simulation. By wirelessly turning relays on and off by sending commands from a PC to a microcontroller we can change the total load (current) to our simulated home. For wireless communication, we used XBee Series 2

Arduino UNO project, Power Quality Meter, someone would call it’s PQ Monitor or PQ Analyzer. I had already published one blog devoted RMS voltage measurements on full band 20 – 20 000 Hz audio signals. ( Following my own style, I’d refer to already published materials whenever it’s possible ). This time measurements performed on

This Instructable will show you how to make a Portable Digital Optical Tachometer using an Arduino Uno. This project is inspired from This instructable and is an enhanced version of it with an LCD display and a modified code. Instead of a slotted sensor , it has a reflection based sensor. So : 1. You

Sure you can use LDR’s, potentiometers and buttons to generate sounds, but what about strings? When I began thinking about an Arduino string instrument, I realized what I wanted to create was a soft potentiometer. I found my inspiration from Hannah Perner-Wilson’s Fabric Potentiometer http://www.kobakant.at/DIY/?p=543. Step 1: Parts Step 2: How it Works Each string is

This Frankenstein Laser Cutter was built out of an old scanner and printer. The whole thing evolved around the instructable of Groover and his ‘Pocket Laser Engraver’. This is a Making-Of. Although a lot, if not everything, of the mechnical construction requires ingenuity I tried to document the complete build process as much as I

Heating things up is one of the most performed tasks in a lab. Quite a lot of times it is not enough to simply hold something at a certain temperature, but the rate at which something is heated and for how long is just as important. Especially when you try to develop catalysts for chemical

Have you ever wondered how migratory birds manage to have such an amazing sense of direction despite being so generally clueless? They can sense the Earth’s magnetic field with what is basically a compass built into their body. Wouldn’t it be cool to feel what that’s like? The following instructions are loosely based off of

We had a project that required connection to a digital micrometer with a data output jack. The idea was to connect a microcontroller to the micrometer, to read the measurements and make decisions based on the readings. The micrometers that we used are made by Mitutoyo, and have a funky 52 character data stream in
