Pyroelectric (“Passive”) InfraRed sensors: ”’What is a PIR sensor?”’ PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don’t wear out. For that reason they are commonly found in appliances and […]

Meet Easy Pulse: A kit that includes all it needs to make a DIY heart rate sensor. Although it is not built using an Arduino, it is still open and easy to build. From the site: “This project is based on the principle of photoplethysmography (PPG) which is a non-invasive method of measuring the variation

Want to tweet how satisfied you are cuddled up in your Snuggie? The Smuggie is a modified Snuggie, designed specifically for those who feel the need to express their smug satisfaction with a Snuggie to their friends on Twitter. Here’s a list of everything you’ll need: – Processing IDE (http://processing.org/)Arduino IDE (http://arduino.cc/) – A Twitter

Scott W Harden has built an updated version of his ECG circuit for tracking his heartbeat. The main goal of the update is to provide a hack for collecting heartbeat with minimal h/w cost and circuit complexity. As you can see from the project photo above, the heartbeat detector is based on photoplethysmogram. Scott nicely describes the basics

[Mac OSX Only] Because I use Quartz Composer, my program works only on Mac OSX. I am now extending and improving it toward cross-platform. If you have knowledge of computer programming, you can make your own system that connects to the blimp. The communication protocol between the blimp and the computer is simple. Read the
We moved house recently and I was obviously very keen to continue the home automation routine. As described in Adventures with an Arduino – Part 1: The Business Problem, I created an Arduino based garage door interface to integrate with a BOSS BOL6 garage door controller. The new house however uses a Gliderol GTS controller –

nspired by drj113’s great instructable on making a word clock, I wanted to make my own. After seeing the (extremely overpriced) commercial “qlocktwo” word clock, I decided to borrow its smooth glossy black design while basing the innards of my clock on drj113’s design. In the end, I managed to stuff the arduino and LED’s

I recently watched an episode of Stan Lee’s Superhumans which featured a blind man who used a series of clicks, like a bat, to echo locate his surroundings. I got to thinking about other blind people and their ability to navigate freely – without the use of a guide dog or cane. I came up
