This is my second version of my arduino robot after “Build your first robot”. My Second version is slightly complicated as compared to my first one but offers better features. In this instructable I’m going to show you how to build a fast robot which can measure temperature, find things in front of it, stream […]

The breathalyzer microphone is a system for the inconscpicuous collection of blood-alcohol content level data sets. In other words, you can measure a person’s sobriety with a device, that for all intents and purposes, looks no different than a standard microphone. This tool adds new dimensions of truthiness to any standard interview. It can also
Introduction We designed a device that measures and graphs various aspects of AC power and acts as a computer-controlled remote switch. With the recent push for green energy and environmental friendliness, more and more people are concerned about their personal daily power usage. We developed a microcontroller-based device to measure AC power. The user will
This instructable will show you how to build a portable Touch Screen Oscilloscope for less than 40 U$! The oscilloscope is one of the most powerful electronic instruments that is available to electronics hobbyist, experimenters, and engineers. It is mainly used to measue time-varying signals. Any time you have a signal that varies with time(
The idea behind this post is to bring together some robot designs and trasform them in a new device with new hardware and standard software (arduino of course) and so easier to use. These robots have three things in common: a mechanical structure, the hardware and the software. While the mechanical part is necessarily different,
The photo depicts a speed controller, wired on a breadboard which allows you to vary the resistance in the potentiometer in order to, in effect, control the speed of the small DC motor. The big picture problem is creating an efficient PWM motor controller that allows for an analog variance of voltage across the motor.
This is a step-by-step on how to connect Arduino to OpenFrameworks using Spacebrew. More specifically our project focuses on the awesomeness of Capacitive Sensing to alter OF projections to create an awesome tactile experience! What the process will involve: Arduino -> Processing -> SpaceBrew -> OpenFrameworks What you will need: Software: Arduino Processing OpenFrameworks Capsense
Capacitive Sensing + Open Frameworks + SPACEBREW Continue Reading
This was inspired by Raj’s personal soundtrack shirt in Big Bang Theory S3, E16, “The Excelsior Acquisition”. You can now buy them online but it’s much more fun to make your own and it’s possible now that buttons designed for use in electronic clothing are available from Connectedwear. Nine of the buttons on the Connectedwear
One of my clocks stopped working – and it happened to be a clock my wife likes a lot. Went to the repair shop and the guy said that he didn’t have the spare parts and could not repair this. So – I thought – why not build an LED clock – I had tons
This instructable builds on top of the Geiger counter triggered LED decorations I made last year. This version powers the Geiger counter from the Arduino (itself now powered from a mains adaptor, so I no longer need to keep feeding them batteries) and the LEDs now fade in and out for a more gentle effect.
