Testing, comparing and monitoring the feasibility of piezo, stepper and magnetic inductors for indoor energy harvesting. The whole system works! The energy harvesters are collecting, the xbee radios are sending storage values, Processing is retrieving the data and posting the values to a database, data is being graphed (both web and phone) via php, the […]

Piezo’s, we have concluded, both MFC or ACI types, are the least effective forms with which to scavenge usable energy. I decided, rather then test only piezo’s in varying environments, to compare three different forms of harvesting in the same location. At the moment I have restricted the harvesting to the two sliding doors that […]

I’ve been interesting in energy harvesting for a few years and knew at the beginning of this semester that it was something i wanted to explore – little did i know how frustrating it would be. Solar seemed limiting and after much research I narrowed it down to either mems or piezo transducers. I latched […]

Our assignment was to build an automated version of the ever popular game: rock, paper, scissors.  Rory and I sat down and built two xbee radios connected to two arduino stamps and coded a hand shake protocol for communication between the two.  It took us about two hours to workout before we uploaded to the […]

This past week was spent installing my project in the front space of the ITP floor. Rob Ryan has been super generous and gave me all the resources i needed to set up this project, test it and revise it. After speaking to him last week and explaining the project, he didn’t hesitate to find […]

As of midnight last night, everything is working again. The last major hurled was getting rid of the micro-controller and working with the chips on the Xbee radios to send and receive data. One master transmitter receives byte values from a video tracking algorithm using the jmyron library in Processing, which blankets out the data […]
