Libyan rebels turn toys into weapons of war

They say all’s fair in love and war – trust us, you don’t have to tell these guys twice.

With the war in Libya raging on, the rebels have turned to anything and everything to help give them the upper hand. Engineers and engineering students have put aside their work and studies to become the architects of the Libyan revolution. In a school playground-cum-weapons facility people from all walks of life work together creating powerful weapons from scrap parts.

[Rajab], the group’s chief weapons engineer, used to drive trucks for a living. Now he is directing his fellow fighters on how best to re purpose scrap materials and recovered military weaponry into effective killing machines. As you can see in the video below, everything is fair game. Their creations range from pickup trucks fitted with recovered fighter jet machine guns, to a Power Wheels chassis that has been converted into a remote controlled machine gun turret.

It’s amazing the things that can be produced with some scrap materials and a bit of ingenuity.

Marvelous Magnetic Machines

[HP Friedrichs] wrote in to tell us about an upcoming book titled Marvelous Magnetic Machines. Ordinarily, we skip over promotional hype. After watching his promo video though, we couldn’t help but share. We want a copy of this book. In this book you’ll find details on how to build a number of different motors from scrap. You can see several variations in the promo video. He also notes that the music was created by himself and some friends a few years ago. If [H.P. Friedrichs] sounds familiar, it is because he’s been sending us fantastic projects since at least 2006.

PCB drill press on a budget

An accurate drill press is an essential tool for making your own through-hole printed circuit boards at home. Reader [Josh Ashby] offers up a solid design using scrap bin materials.

A major issue with PCB drilling is that even the slightest horizontal play will snap the delicate carbide drill bit. Hobbyist-grade tools such as Dremel’s drill press attachment are usually too sloppy for this task, while a more precise instrument might set you back a couple hundred bucks.

[Josh’s] design uses a nylon “sled” moving vertically in an aluminum u-channel track. Most of these materials were salvaged or were acquired inexpensively from a local hardware store, and assembled in less than a day. Surprisingly, this low-tech approach has proven sufficiently smooth that he’s yet to break a bit while drilling. And the entire setup, including the knockoff Harbor Freight rotary tool, cost less than the wobbly name-brand accessory alone.
