What’s all this? This instructable will explain how to build a fairly basic but working spectrophotometer out of easily sourceable parts. Of course, this device is nothing compared to a commercial spectrophotometer, but it will allow the builder to understand how such a device works. Huh? What are you talking about?! A spectrophotometer measures the […]

Have you ever wished lunchtime were longer, but didn’t know where to find those few extra minutes? Well, wish no longer! Thanks to great in advances in clock technology, I present to you a clock that speeds up 20% every day at 11:00 and slows down 20% every day at 11:48, giving you an extra

Previously, we introduced the Arduino’s analog-to-digital converter (ADC) in detail, looking at successive-approximation A-D conversion and how it’s the best compromise between speed and cost. This time, we start putting some of that theory into practice by building a stereo peak-program meter. Our Peak Program Meter (pictured above) takes audio from any phone or tablet.

Yes, this is more or less your average touchpad that one can find from inside a laptop. This model, like majority of touchpads out there operates with PS/2 standard. This means that it can be directly plugged in to a PS/2 connector and with proper drivers, function as a mouse. As it happens the PS/2

GSM is quite a common Device which is used in major Projects and Real Time Operations. There are many applications which are using features of GSM Module like the feature sending Messages, making a Voice Call, Reading Messages, attempting Call etc. Many at times you may have sent Messages using your Cell Phone and also

I wanted to create an Arduino instrument that was easy to play, but would sound better with practice. This “wind” instrument combines the Sparkfun Electret Microphone breakout board with the Tone library and 5 buttons on one analog pin. The musician must make a sound or blow into the microphone in order to enable the

An Arduino Duemilanove (other boards will probably work, but you will have to adjust the steps for your device) Working NES Console Super Mario Bros. (Note: this must be only the single game, not the two- or three-in-one cartridge) A controller you can cut the cord from Two LEDs (two different colors are recommended but

In this instructable you will learn how to make a Q&D-Poor man’s-Skinner-Sadist-Jeopardy game . First off, the disclaimer: I’m not responsible of whatever you do. You have to know that with a great power comes…bla-bla-bla. Just be careful and remember that electricity reserves respect. While the energy involved in this project is generally safe, it

Flying model rockets is fun, but there is always the question of how high did it go. Using a programmable micro-controller and some sensors, you can monitor the entire phase of flight and measure acceleration and altitude, among other things. With this project, I’ll show you how I did just that, using off-the-shelf open source hardware and

While being a bit lengthy and requiring experience with Arduino, this contraption is bound to grant you infinite glory among your friends, toddlers and grownups alike! Step 1: What You Need Here’s a list of the materials and parts I used: The Frame * 5 x 4-feet long rectangular profile (0.5″ x 0.5″) pieces of
