I didn’t think it was possible but MIT researchers have actually done it. Its based on a concept that NASA originally used where their space probes harvested heat from radioactive plutonium. Semiconductors can produce a similar effect between its hotter and colder sides and Enocean have a patented bit of kit that does just that. These self powered […]

Posted on June 11th, 2013 by bud
Creating a solid object from a 3D CAD model has become extremely easy. There are many ways of doing it, but essentially they all follow the same process: 1.The 3D CAD model of the object is “sliced” into many thin layers and fed to the 3D printer. 2.The 3D printer (through various different methods) prints […]

Apart from the firing pin and the bullet, this gun has completely been made using a 3D printer. The “liberator” (pretty apt for the anarchist group!), created by Cody Wilson, is entirely undetectable by metal detectors and the plans were released online for free last week. Naturally New York Senator Chuck Schumer is introducing plans […]

1. Determine how you would like the code to be displayed First, decide how you would like the code to be presented, the most common options are: A full, abbreviated or numerical form of the date: For example, 1 January 2012, 31 Mar 2012, 1.6.2012 and 01.08.12 are all quite clear. Julian dates (these are not […]
