Who doesn’t love music? These Piano Stairs are an interactive, relatively portable, musical installation that can be applied to basically any stairwell. I built them for HackPrinceton and won 2nd place in the hardware track. I’ve had requests to share my code and diagrams, so I decided to make an Instructable! These piano stairs use […]
Make PPE milk bottles into good looking LED lights, and use an Arduino to control them. This recycles a number of things, mainly the milk bottles, and uses a very low amount of power: the LEDs apparently dissipate less than 3 watts but are bright enough to see by. Among other things, I wanted to […]
The DIY Cellphone is a working (albeit basic) cellphone that you can make yourself. It can make and receive phone calls and text messages, store names and phone numbers, display the time, and serve as an alarm clock. It connects to GSM networks (like AT&T and T-Mobile in the U.S.) using a regular (full-size) SIM card. It […]
In this project we’ll create a small add-on PCB containing the a MSGEQ7 spectrum analyzer circuit and show how it can drive the RGB LED cube kit from Freetronics. This allows the cube to display the seven bands over four horizontal planes. There is a small amount of assumed knowledge for this project – To save repeating […]
High speed photography is generally carried out in a dark room with dedicated equipment (controlled remote flash for example)… The instructable proposed here enables to make high speed photography outside (and enjoy the sun!), in less than 2 hours with some generic DIY basic tools. The principle is the following : A marble is dropped in a repeatable way. During […]
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 […]
Last winter I experienced some problems with my car battery. I knew that it was about time to replace it so off I went to buy a new one. This fact reminded me of an old article about a car battery/charging system diagnostics kit I had seen in one of those 1980s electronics magazines. That […]
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 […]
I started this project because I wanted to make something that had mechanical, electrical and software components. After looking around on Instructables, I figured that an Arduino based laser engraver would be an interesting machine to make, and that the machine itself could make interesting things. Laser diodes have also advanced quite a lot in […]
Introduction This is the second in a series of tutorials examining various uses of the Arduino Yún. In this article we’ll examine how your Arduino Yún can send data that it captures from the analogue and digital inputs and a real-time clock IC to an online Google Docs spreadsheet. Doing so gives you a neat and inexpensive […]
