Audio Frequency Spectrum Analyzer & Spectrogram As a followup to a previous post on Music Visualization with Processing (and a good excuse to play with my Arduino), I decided to convert my Processing music visualizer into hardware. The project is not finished yet, but I wanted to post a quick update and how-to on making what … Read more
April 2010 Simple Powerline Remote Interactive Monitor and Enforcer SPRIME is an outlet that allows you to monitor power consumption and control power usage remotely, using a computer or even an Android phone. SPRIME is an open-source smart-grid technology. SPRIME GT-RNOC poster: SPRIME pictures: Awards SPRIME has made it on Hack-a-day! SPRIME has won … Read more
February 2010 I followed a circuit diagram on the Internet for making a guitar distortion, then stuffed it in a Curve cologne tin box. It sounds pretty good for a DIY project!
August 2009 This is an Arduino microcontroller that I wired into my car’s ECU and programmed to calculate the instantaneous/average miles per gallon of my 2002 Honda Civic. The circuit reads pulses from the Vehicle Speed Sensor and Fuel Injector wires. It is wired into my car via a USB cable. It’s pretty accurate once calibrated. My … Read more
June 2008 I used a PIC microcontroller in a circuit to measure my car’s MPH. It measures the frequency of pulses from the Vehicle Speed Sensor, and converts it to miles-per-hour. A summer project involving programming a PIC micro controller to measure my Honda Civic’s MPH. The circuit I made measures the frequency of the pulses coming from … Read more
