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 […]
Have you ever wanted to impress your friends by saying something crazy like, “I think there’s going to be an earthquake soon” moments before an earthquake hits? Or do you just want some warning, a few seconds that could save your life. This project will allow you to hook up a seismic sensor to a […]
This project was inspired by this video from YouTube and the Pendulum Challenge Kit from Makershed.com. Its a simple game consisting of five LED lights and one pushbutton switch. The LEDs flash in a sequence and the player must press the button when the middle LED light is lit. The speed at which the lights […]
In this instructable i will explain how to connect 7 segment display, decoder and arduino. It´s pretty easy. At first we have to learn something about decoder. I´m using BCD to 7 segment decoder. My is D147D, this is old chip, but the newer are similar. Documentation about one of them you can find here […]
In this Instructable, I’ll be explaining how to build a motion activated alarm! It uses an Arduino microcontroller, a PIR (passive infrared) sensor, and a type of alarm. You can use an LED indicator, a buzzer, or a piezo. That’s the easy part. I will also be showing how to display to a character LCD […]
2000 pictures compose this piece- that is, 2000 perfect different water drops into which we mapped an animation. Droplets that behave and look strangely similar at the stage of less entropy, and become more disorderly as they splash. The final result of the piece you have seen has absolutely no CGI, and was shot in […]
Have you ever wanted to, without going out of your way to clock your processor, see how much stress your computer is under? With this project you will have a simple bar graph that constantly shows how much stress your computer is under. If the graph reads 0, your computer isn’t working too much. If […]
This Instructable details how to build a holiday dreidel display for your roof. It uses coat hanger wire, rope light, and an Arduino controller to control a fading demo mode and a “spin” mode. In the demo mode, the symbols fade in and out, going from one to another. In “spin” mode, the symbols flash […]
Arduino & Visual Basic 6 Light Controller This project illustrates an early attempt at bridging Visual Basic 6 (VB6) with the Arduino platform through serial communication over a USB interface. While the concept originated as a beginner’s exercise in VB6 after only two weeks of learning, it highlights important principles of cross-platform interaction, string parsing, […]
Bryan Zimmer emailed us this fantastic retro-themed DIY hack, a most timely submission as we just revisited the noir art deco-science fiction classic Dark City and we think this would have perfectly fit in the world (or in Adama’s quarters on BSG). Bryan gives step-by-step instructions of how he converted a 1940’s Swedish-made Ericsson bakelite […]
