Fresh hacks every day
Instructables user [Dustyn] recently constructed a wind-based lantern to provide a bit of free, renewable light in urban settings. The project is based around a vertical-axis wind turbine, which she says are better suited to these environments since wind often comes from all different directions.

Just as he was putting the finishing touches on his … [Read more...]

It came in what is obviously a laser cut wooden box, a material that tends to make … [Read more...]

Consisting of an LM1881 video sync separator, a handful of passive components, and a stylish PCB in the standard Arduino shield footprint.
