This has been done before. There are several good ways to do it: most use either a 555 timer chip and decimal counter chip, or an Arduino. Stefan and I used an Arduino (Boarduino, technically) which limited our scanner to 14 LEDs. No problem — 14 gives a nice scanning effect! Here’s how we wired […]

In line with broadening of our services and support to our products, we offer you a possibility to get off of troubles with printing of labels and other markers for devices, cables, terminal blocks,… We offer you a service of a preparation for print and printing of labels and terminal blocks itself according to your […]

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 […]

Project summary I found those beautiful vintage IV9 & IV16 tubes and I had to use them, clock being the perfect candidate. I made already mutliple others based on what was supposed to be a WordClock (hence the project name) only, but became more diversified. I did also a first test with a chainable 5cm […]

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 […]
