How to Build an Air Guitar With Arduino, Aka the AIRduino Guitar

The idea here is to build a wearable virtual guitar that is to be controlled with two hands much like playing Air Guitar. It has been created and prototyped during a two weeks project at ChalmersUniversity (Sweden) for a Physical Computing class. The aim is to get the feeling of playing a real guitar. The AIRduino Guitar is made of one glove and one stick. The glove is used to set the tone and the stick to ...

Space Race Game using Arduino and Nokia 5110 Graphical Display

Programming has always been fun and it just got a lot better with development platforms like Arduino. Almost every programmer out here would have tried to develop some kind of game using the language that they learning/practising. This helps them to tune their programming skills in a fun yet productive way. I have been a big fan of Arduino ever since I got introduced to it and always wanted to try something ...

The Aurora Boxealis – A Color Sensing and Mirroring Project

Introduction Besides looking damned good on an otherwise bland and ordinary desk, this project is about more than just being attention grabbing eye candy.  It’s about demonstrating a small portion of our single board computer capabilities by hooking up a color sensor, RGB light strip, and enclosing it in a nice looking wooden enclosure.  We’re dubbing it the “aurora boxealis”, and it’s made to stand out fro ...

DIY Time Control Machine

This project is about how to make a time machine! This machine looks like a glove, and can "stop" any moving subject. At first, watch a video with some demonstration and experiments, guess how it works, and then read about how to make it =) This effect looks like better in real life (by naked eye, not through a camera), without black lines. Smooth perfect time stop effectc!! IT IS REAL "OH MY GOD" REACTION! ...

Arduino Color Mixing Lamp using RGB LED and LDR

What if we can generate different colors using a single RGB led and make our room’s corner more attractive? So, here is a simple Arduino based color mixing lamp which can change color when there is change in light in the room. So this lamp will automatically will changes its color according to the light conditions in the room. Every color is the combination of Red, Green and Blue color. So we can generate a ...

Fluke/Philips PM66xx Frequency Counter OCXO Upgrade

In this post I will document an OCXO upgrade board I designed for the Fluke/Philips PM66xx line of frequency counters. Introduction A few months ago I purchased a Philips PM6674 frequency counter on eBay. It's an older 9 digit counter with two channels that has a maximum input frequency of 550MHz. The design feels dated compared to more modern counters, such as my Agilent 53131A. However, it is still a full ...

Voice Controlled LEDs using Arduino and Bluetooth

Controlling LEDs with voice command seems to be a difficult task, but it’s easy and you can quickly build it. We just need an Arduino UNO to serially communicate with HC-06 Bluetooth module and a smartphone to send voice command to Bluetooth module HC-06. For receiving voice command we are using “Arduino Bluetooth Voice Controller” android app which you can download from play store (link is given below). Ma ...

Arduino IR remote and Software controller

This one is an interesting one, it’s something we’ve been looking at for a while and figuring out how to solve it. We have sets of speakers and projectors and the users keep losing the remotes, or misplaced/stolen. Usually this wouldn’t be a problem, we’ll just contact the supplier or manufacturer and order replacements. Except we can’t any more. We have a set of Vision AV-1000 wall mounted active speakers, ...
