I spent the evening with a good friend of mine, Matthew Flego an industrial designer, at his metal fabrication shop, Ferra Design in the Brooklyn Navy Yards. He and I plotted out the design for a 12 gauge stainless steal housing for the inDOOR Harvester module in Solid Works, a 3d object CAD application. The […]

A glimpse at the revised version of the online dashboard monitor for the energy harvesting module. It been a big javascript learning curve this past week, but well worth it. Many more features and improvement still to come, as well as further data integration. check it out – let me know what you think.

I’ve spent the last two week testing and researching linear motion guides, blocks and rails, to carry the gear motor along the door and across a rack. Due to exploding bearings and bent rails, McMaster-Carr has both saved my thesis and made a nice chunk of change. A far more effective and elegant system from […]

Energy Graph


The available ambient power is the energy produced by the generator as the door opens and closes. Basic testing on the prototype with a dc-gear head motor with a 10:1 gear box and a 1″ spur gear running 12″ along a rack produces approximately 2.5v @ 184mA charging a 1F 5.5v capacitor. The system power […]

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 […]

I’m generally not one for inspirational quotes, but i came upon this again while waiting for the subway after the first snow of the season had already turned grey and yellow. “It is something to be able to be paint a particular picture, or to carve a statue and so to make a few objects […]

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 […]
