Science

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!

Layer-additive “welding” 3D fabrication

Electron Beam Free-Form Fabrication (EBF3) is a rapid prototyping technology developed by Karen Taminger of NASA’s Langley Research Center. Dr. Taminger is prone to market EBF3 by analogy to Star Trek style “replicator” technology, which is nothing but shameless hype. Still, the basic idea is an interesting twist on extrusion-based 3D printing technologies (although there’s not really any “extrusion” going on), and is under development with an eye towards space-based fabrication. Working in outer space would eliminate the system’s major ground-based shortcoming, which is the requirement for maintaining a vacuum or inert atmosphere to prevent oxidation of the weld.

Driving a car with an iPhone. A freaking car. For reals.

John Boiles, who earlier this year showed us how to control an RC car using an iPod’s internal accelerometer (and also how to control the lights on a dance floor in more or less the same way), is a member of Austin, TX, based engineering collective Waterloo Labs, who have up-gunned his iPod technology to control steering, breaks, and acceleration on a full-size automobile. Definitely not the safest hack I’ve ever blogged, but probably the most impressive. Great work, lady and gents.

Telescope camera mod

Telescope camera mod

Craig Smith sent us these pics and note: My telescope is low end in the scope-world, a 60mm refractor. But I discovered the eyepiece is the same size as my digital camera telephoto lens. My digital camera is low end in the camera world, too, a 3.2MP. But put them together with a custom PVC […]
