Kinect + Tesla Coils: Those Fools At The Academy Laughed At You…
If you only watch one online video today, it should be this one. Or at least the first 10 seconds of it. That guy is my new hero. [via adafruit]
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!
Collin’s Lab: Homebrew Piezo
Piezoelectric materials are about as close to magic as you can get. They turn physical pressure into electricity and can even turn electricity into physical pressure – an amazing sort of bidirectional converter for mechanical and electrical energies. Perhaps even more amazing is the fact that you can easily ‘grow’ your own piezoelectric crystals overnight using just a couple of common ingredients – awesome.

Working Handheld Homemade Pulse Laser Weapon
The claim of penetrating a razor-blade impresses me, although I note the only metal penetration in the video is thin aluminum, which has been painted, possibly so that it will absorb more light energy. Thereโs also some cool shots capturing the pulsed-laserโs plasma ball in midair.
Is It Time to Rebuild & Retool Public Libraries and Make “TechShops”?
To me, public libraries โ the availability of free education for all โ represent the collective commitment of a community to their future. They symbolize what is most important, a commitment to educating the next generation. The role of a public library should also adapt over time, and that time is finally here. It’s time […]
Polar Bear Spy Cams
These covert cameras employed by wildlife videographer John Downer imitate natural elements of the Arctic Norwegian environment to grab an insanely closeup view of the polar bear’s journey. Jacob Resneck at Cool Hunting writes: Downer employs three types of cameras to track the lives of two mother bears as they lead their clubs across Arctic […]
