[Dale Dougherty] interviews [Steven Levy] about the history of hacking. [Levy]’s book Hackers has been released in a 25th anniversary edition. The interview alone is fascinating and the book is a must read for any hacker. If they offered a course in hacker culture somewhere, we’re positive that this book would be the textbook. The 25th anniversary edition has been updated to include major figures from the last 25 years including [Bill Gates], [Steve Wozniak] and others that have impacted our lives drastically.

Cat Hacking

After a gruesome accident involving a harvester, [Oscar] lost his legs. [Noel Fitzpatrick] a mad scientist veterinary surgeon came to the rescue. [Oscar] now has leg implants prosthetic feet. It is pretty amazing that a cat would even function in this manner. Have you ever seen one try to walk with tape on its feet? We have to wonder why that cat doesn’t have some more awesome looking legs though. We think that cat needs to team up with [Aimee Mullens], the olympic athlete with no legs, to get a better looking pair.

Multitouch Using Water

[Taichi Inoue] is back again, this time with a multitouch system that uses water as the touch surface. The setup consists of a tank of water placed atop an LCD, a lamp, and a web cam. The web cam pics up the light that is reflected when something breaks the surface of the water. It is, as far as the computer is concerned, no different than the blob recognition we see with many of the home made multitouch systems. Mixed with his Yukikaze, this guy might end up with the most relaxing computer system in the world.

Yukikaze, Music Visualizations

[Taichi Inoue] put together this beautiful visualization system called Yukikaze, japanese for “snow wind”. Basically a spectrum analyzer, Yukikaze is delightful to watch. We would love to see what kind of response he gets, as most of the footage shows very slowly changing smooth jazz. While we don’t think he gets crisp EQ visualizations out of this since it is a single large chamber, we still think it is amazing to watch.

Like many specialty plants, growing mushrooms requires that you keep a fine balance between humidity and temperature. this can be fairly tedious at times, so many opt for automated systems. [Anthony_p1234] has chosen to build his own. Using an Arduino, he controls power to two heating pads, a sonic humidifier, and an air pump to keep his mushrooms happy. He shares the process of building the system, testing and calibrating the parts and putting it all in use. We didn’t see any schematics, but he does describe everything fairly well. The source code is available for download.

Mr. Burns Prevents Sun Burns

June 24, 2010 by Caleb Kraft 13 Comments

[nmcclana] wrote out this very detailed instructible on building Mr. Burns, a sun burn alarm. Enter your skin type, sunscreen type, and UV levels for the day and Mr. Burns will let you know when it is time to go seek shelter or re-apply that sunscreen. Built on a Propeller platform, he’s using a blue LED as the UV sensor. He mentions that the device is fairly accurate, however people tend to put sunscreen on too thin and that will throw off the readings. There is a video of it in action on the instructible.

Giant LED Matrix

June 23, 2010 by Caleb Kraft 6 Comments

We all love blinky lights. What we love even more than blinky lights is a very detailed tutorial with great photos. [Richard Kline] has written this fantastic tutorial on how to build a large 5×7 LED matrix and control it with a PIC processor. The bulk of the body is a foam insulation board, covered with a diffuser. Source code and schematics are available for download from the site. If you’ve ever thought about getting into PIC processors, this would be a great beginner project.
