Fresh hacks every day
While we could be content following our "kiddie d-day" as [Caleb Kraft] suggested. We know you can't continue such an awesome Friday without trying to blow yourself up first. This Wiimote Rubens' tube caught our eye. A PVC Aluminum irrigation pipe is drilled with holes and propane is pumped through. A speaker on one end creates changes in pressure and a neat light show follows suit. … [Read more...]
This giant Madagascar hissing cockroach rides proudly atop his three-wheeled robotic platform. This project from several years ago is new to us and our reaction to the video after the break is mixed.
