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 [...]
Cockroach pimps a sweet ride

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.

It is a nice clean circuit that can be adjusted and fine tuned to your specific needs via some trim pots and dip switches. [via [...]

Minifigs beware, something’s afoot. This LEGO sniper rifle is in talented hands to clean up those problem areas. [Jack Streat] put together this fascinating build as well as the delightful demo after the break. The bolt pulls a 1×4 block out of the eight-round magazine and loads it into the chamber. A pull of the [...]
