There’s something so elegant about this project. In addition to liking the overall design, I really like the educational aspect of these solar shades – having kids learn about solar energy, and the importance of finding the most efficient angle as they turn the panels. On the other hand, it is still extremely wasteful, like [...]

What I’m trying to understand is how to make a slightly smarter circuit for the Roof-Link project (the mesh network of Xbee chips that send sensor readings from the 12th floor solar panel, down to our department on the 4th floor). What happens now, is that the 12th floor module senses the voltage coming in [...] Eric and I set out on a journey to create the ultimate experience for hoodie lovers. We wanted to make use of all that doodling around with the back and forth string movement of the hoodie, and actually generate electricity from that. We used a string with rare-earth magnets, going through a plastic tubing, which [...] Our assignment in sustainable energy was to work on producing electricity from a stepper motor. Hacking the life out of an old scanner I had lying at home produce two stepper motors. Connecting them to two diode bridges (rectifiers), turns the AC voltage generated by turning the motor into DC (diagram here – I used [...] |
