If You’re Going To Kill It, Open Source It! @ MAKE… [via]
Another week, another company killing off a giant product after spending millions of dollars and years developing. Back in 2009 Cisco bought Pure Digital Technology’s Flip. Gadget fans and makers were puzzled by this; phones were just about good enough to start beating the Flip. Now, it’s heading for the landfill.
Some companies fail, some kill off product lines that are not profitable, but in the end, where does all the knowledge go? Nowhere, usually. In a world of disposable everything, is it time that we demand companies do what’s good for humankind in addition to the bottom line?
If companies are going to just kill something off, why not open source it? Some companies do just that, and others, like Nokia, will promise open source (Symbian, dead product) and then quickly reverse itself, locking it up. Pictured above, a Nokia coffin.
In this article I’m going to share my collection of products that no longer exist but should (or could) have been released as open source projects. Part of the goal is for you to post the ones you’d like to see “open sourced” as well. My list includes some familiar favorites, like the Sony humanoid robots, to some old timers like Ricochet wireless cards.

BoxMaker is a little Java application that can generate the outlines for a box to be out of some material with a cutting device (ideally using wood/acrylic on a lasercutter!). You tell it the dimensions of the box (width, height, depth, material width), and it generates a PostScript file with the outlines for the 6 sides of the box. The dimensions are the outside lengths of the box. [via]
