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 […]
3D AIR mouse | Arduino + Processing I’m an Industrial design student, and last year as part of a course called “Technology as RAW materiel” I built this project as my final work. I work most of the time with SolidWorks, a CAD software for design and engenering. Rotating a solid body on the screen
This sketch shows you how to read and calibrate the Esplora’s light sensor. Because light levels vary from one location to another, you need to calibrate the sensor for each location. To do this, you read the sensor for a few seconds, and save the highest and lowest readings as maximum and minimum. You’ll use
When I got my Arduino protoshield from sparkfun, I wanted to make something cool with it. And since I had seen a few Theremin projects before, and already thought about making some, I finally made one, using the Parallax PING sonar sensor. Here are some informations about how I made it. You can see all
Small 4-wire resistive touchscreens are now amazingly cheap: they are produced in such enormous quantities for mobile phones, PDAs, and particularly handheld games such as the Nintendo DS that they can be bought brand new for under US$10. Larger touchscreens are also rapidly falling in price. The popularity of netbooks with screens between 7″ and
Bring out your 3D glasses and enjoy viewing in a novel way! I have added a new dimension to my instructable. If you do not have 3D glasses, then you can make one yourself. The following link explains how to make 3D glasses ( link ). Please Note: This instructable contains 3D images which are best viewed with

The Arduino offers the advantage that a lot of people are using it so it is usually quite easy to get help or information via the internet. The main website for the Arduino is: http://www.arduino.cc/. The Arduino can also be programmed to behave in many different ways. It has 6 analog pins (continuously varying controls
This was created to be some eye-candy for my kitchen. I wanted something unique for a special blank space on my wall, and adding movement, blinky lights and interesting mechanical “guts” made it even better. Ultimately, this project ended up requiring the following range of skills: 1. Basic mechanical skills 2. Light metalworking and fabrication
Origami is the traditional Japanese art of paper folding. In this project, with a little help from an Arduino, you can bring your origami into the 21st century and make it an interactive art! The result shown here uses Bare Conductive paint to give an origami flower proximity sensing powers. When you put your hand
In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan. When the button is pressed the fan will turn ON and will remain in this state
