QR codes are addicting. Smartphones are smart enough to read them from virtually any angle or orientation. But imagine taking it a step further. I had dreams of a digital LED array that I could program with QR codes, and I wanted it really big! I used 16 matrices to create the QR code that […]

During the past spring a good friend of mine bought me my first house plant, a Lady Palm, and I’ve found myself rather invested in keeping it alive. To that end I wanted to monitor the plant’s environment so I could ensure that its needs were being met. My first thought was another ITP project,

A “fan cart” is a roughly constant-force device used in introductory physics labs. It consists of a fan (usually a model airplane propeller on a brushed DC motor) mounted on top of a low-friction cart. Students use it to pretend they’re learning something about force, acceleration, energy, etc. If you’ve ever taken an introductory physics

This device captures the IP address of your network and it publish on site DynDNS.com. All without PC. It allow a remote access to your LAN even if the IP address of the connections changes. For logistics reasons the provider can not assign a IP fixed for all users, so many users, especially private, work

Once you’re getting some values from sensors, for example using Arduino, (see my previous instructable), sometimes it’s nice to see the sensor data in a graph. Here’s how in only a few steps! I made this particular Instructables using a sonar sensor (XL Max Sonar EZ/AE) but you can do it with any data values

Make a game pad with an accelerometer inside! This project tutorial will show you how you can convert a console game pad into a USB keyboard mouse for playing games on your PC. The USB game pad can be used with nearly any software, such as a MAME emulator, game, simulation software, or for custom
USB Game Pad With Tilt-accelerometer Mouse using an Arduino Continue Reading
In an earlier post I described an Arduino-controlled fan cart. The driver I used was an L293D quad half-H chip, because I had one handy and was out of simpler parts at the time. It’s always bugged me that I was just controlling speed on that cart, since it’s possible to control direction with an

This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here. Making a plant sing has been a trick since the Theremin was invented. Here I am going to teach you how to do this with and arduino board, a gameduino shield and a the touch shield

This is the second part of our BaW-Bot (Bells-and-Whistles Bot) build – 5 separate instructables that look into different Arduino-related technologies, combining to create a Bot with all the bells-and-whistles. Part 1: Build an Arduino on a Board Part 2: Build the motor-controller & body Part 3: Adding Sight and Touch Part 4: Blinging up

One of my colleagues, Dr. Shane Mayor, has built a very nice LIDAR system for atmospheric research. It’s located at a remote site, at the end of a dirt road, and everything about the system can be controlled remotely except the main pump laser power supply. That supply has a key-switch, which has to be
