This Instructable explains how to use a gas sensor with your Arduino. This lets your Arduino smell (and hence you program responses to) overall gas levels for a variety of nasties, including ethanol, methane, formaldehyde, and a bunch of other volatile organic compounds. My cost to make this actual device was under $100, including the […]

In this Instructable, I will step through controlling the temperature of most kitchen appliances. As an example, I will use an old Westbend Poppery popcorn maker (aka. coffee roaster), but these same techniques will be applicable to most hot plates, coffee makers, and waffle irons. This instructable puts you at risk of electrocuting or burning

This Instructable will show you how to modify an Altoids tin for a wireless 2×16 character display. Using an Altoids tin was inspired by the need to have a small yet protective enclosure for a pair of Xbee modules recently bought from Sparkfun. I purchased the Xbee Pro modules with external antenna for the extended range

Protect your secret hideout from intruders with a lock that will only open when it hears the secret knock. This started out as a bit of a joke project, but turned out to be surprisingly accurate at judging knocks. If the precision is turned all the way up it can even detect people apart, even

I’ve been really interested in doing J4mie’s Physical Gmail Notifier ever since it came out in February. I only recently dropped into the project and got to learn a lot about python, plists, and arduino auto-reset functionality. I’m going to share what I’ve learned because I think there are lots of other people out there

It’s been only a couple weeks since I discovered Arduino, an open source microcontroller platform. I was looking for a cheap interface between my laptop and electronic circuits. Arduino with its price $35 and easy to use development environment was the best choice. So after getting my Arduino Duemilanove board and ordering some cheap components

We’ve covered loads of airsoft, nerf, and gun projects, and here’s another superb pr0ject to add to our collection. It’s a coil gun placed on a turret which is triggered via Wi-Fi. Additionally, it uses remote targeting and shooting through an iPhone, iPod Touch or iPad. Don’t Miss: Our collection of airsoft and gun projects

What is it? It is a decorative lamp; a very, very impractical decorative lamp employing a few vintage display devices and a couple of LEDs too. A friend of mine was one of a group of artists who produced Ascension (the giant origami-crane tent) at the 2010 Coachella Music and Arts Festival. Since he was

I love the Arduino as a simple and accessible controller platform for many varied projects. A few months ago, a purchased an Ethernet shield for my Arduino controller to work on some projects with a mate of mine – it was a massive hit – for the first time, I could control my projects remotely
Not everyone wants to look like an athlete while cycling to work or school. This cycling-jacket, made of hemp and wool, is equipped with lots of shining bright LEDs. It looks just as good during the day as it does during the night. Embedding the Arduino Lilypad electronics in the jacket, makes it at practical
