DIY science is the perfect way to use your creative skills and learn something new. With the right supplies, some determination, and a curious mind, you can create amazing experiments that open up a whole world of possibilities. At home-made laboratories or tech workshops, makers from all backgrounds can explore new ideas by finding ways to study their environment in novel ways – allowing them to make breathtaking discoveries!

UK engineer makes own aortic implant, saves own life

UK engineer makes own aortic implant, saves own life

Well, OK, admittedly Tal Golesworthy had a team of respected doctors and medical imaging experts to consult with, but, as he puts it, “[w]hen you’ve got the scalpel of Damocles hanging over your sternum, it motivates you into making things happen and so they do.” Only two years elapsed between his fateful diagnosis and his recent successful surgery. The implant itself was designed on a computer based on digital imagery of Golesworthy’s heart, and fabricated on a form made using a rapid prototyping technique. Check out all the details at The Engineer. [via Boing Boing]

Math Monday: Five tetrahedra

By George Hart for the Museum of Mathematics Here is a geometric assembly challenge which you can try to make with wooden dowels or any other conveniently long cylinders. Each of these thirty aluminum rods touches ten others. The construction is rather tricky to accomplish even if you properly understand it as a compound of […]

How-To: Ultralight camp pot from Heineken “keg” can

How-To: Ultralight camp pot from Heineken “keg” can

In the summer of 2002, Heineken introduced its 24 oz. “mini keg” can in the US. Besides having twice the volume of a normal aluminum beverage can, the “mini keg’s” unusual design includes a number of ridges and rings that make it much more rigid. Sometime around 2004, so far as I can tell, ultralight backpacking enthusiasts began experimenting with using the new can design as a cooking pot.

The community has evolved the design of these cooking pots to a remarkable extent, and although there seem to be as many variations as there are builders, a few common features seem to be emerging:

1. The top of the can is removed with a side-cutting can opener and preserved for use as a lid. The tab may be bent up to provide a handle, or a small knob may be attached.
2. The side of the can is wound with 1/16″ fiberglass wick to provide an insulated gripping surface
3. An elastic silicone wristband is stretched around the rim of the can for drinking comfort.

I’m sure to screw it up if I try to give any particular person “credit” for any of these ideas, but the embedded video overview from Minibulldesign Cult gives the best general overview of the idea I can find. And Rick of Wilderness Survival Forums has produced a good phototutorial describing the fiberglass winding process.
