Description The AH1898 is a micropower magnetic range selectable (Bop/Brp) Omnipolar Hall effect switch IC with internal pull up and pull down capability, designed for portable and battery powered consumer equipment such as cellular phones and portable PCs. To support battery powered equipment and low voltage microcontrollers, the AH1898 can operate over the supply range […]

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( […]

In this instructable I am going to show you, how to paint a black and white image of Darth Vader and bring it to life by adding a binary clock and making it talk. If you are not a big Star Wars fan, don’t worry you can use the electronics and code to make any […]

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. […]

I finally finished my Arduino Monitor/Tester! This is how it turned out to be: One LED for every single input or output Can be used with Uno, Leonardo, Mega, Due, Mini, etc. Also fits with my universal I/O board Power taken from Arduino 5V and 3.3V outputs, and the Vin Load on any pin is […]

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 […]

Abstract   ISO 26262 is intended to be applied to safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production passenger cars with a maximum gross vehicle mass up to 3 500 kg. ISO 26262 does not address unique E/E systems in special purpose vehicles such […]
