The Jargon File describes a wizard as someone who groks something to a very high degree, or the kind of person that builds a polymer concrete CNC machine with a pneumatic tool changing spindle that they designed by themselves. It makes you think that maybe Tony Stark COULD build it in a cave with scraps.
It’s a five part video series showing snippets of the build process. The last video gives an overview of the design of the machine. It is all very much in German, so if you speak German and we got anything wrong about the machine or missed anything cool, please fill us in down in the comments.
The machine starts with a 1500 kg polymer concrete pour with some steel stock embedded in it. It is then machined within an
inch mm of its life as shown by practically zero deviation over its length when measured against a granite block. The wizard then goes on to make his own spindle, get castings made, and more. We liked his flowery kitchen hotplate, which he used to heat the bearings for an interference fit. It added a certain amount of style.
Unfortunately the videos don’t show the machine running, but we assume this sort of person is happily building arc reactors, power suits, and fighting crime. They probably don’t have time to film “CNC Bearbeitungszentrum im Eigenbau Teil 5”. Videos after the break.

The 31st annual Chaos Communications Congress (31C3) kicked off today and you’ve already missed some great talks. If you’re not in Hamburg, Germany right now, you can watch the talks as they happen on the live stream. So stop reading this blog post right now, and check out the list of presentations. (But don’t fret if you’ve already missed something that you’d like to see. All the talks are also available after the fact.)
For those of you whose worldview is centered firmly on the You Ess of Ay, you’ll be surprised to learn that the Congresses are essentially the great-grandaddy of the US hacker conventions. If you’re one of the many (old?) US hackers who misses the early days of yore before DEFCON got too slick and professional, you’ll definitely like the CCC. Perhaps it’s the German mindset — there’s more emphasis on the community, communication, and the DIY aesthetic than on “the industry”. It’s more HOPE than DEFCON.
This is not to say that there won’t be some great hacking showcased at 31C3. It is the annual centerpiece of the European hacker scene, after all. Hardware, firmware, or software; it’s all exploited here.
Some of the talks are in German, naturally, but most are in English. If you haven’t attended before, you at least owe it to yourself to check out the live stream. Better yet, if you’re a member of an American hackerspace, you can at least set up local remote viewing for next year. Or maybe you’ll find yourself visiting Germany next Christmas.

The e-volo VC200 has made it’s maiden unmanned flight. Does the craft above look a bit familiar? We first reported on the e-volo team back in 2011. Things have been going great for the team since then. They’ve created an 18 motor (Octadecacopter?) prototype dubbed the VC200. The group has taken a smart approach to building their craft. Rather than try to keep everything in-house, they’ve created a network by partnering with a number of companies who are experts in their fields. A sailplane company laid up the carbon fiber composite frame for the EC200. Junkers Profly, a German aviation company, developed a ballistic parachute system in case something goes wrong in flight.
From the outside, the VC200 looks like a grown up version of the Quadcopters we’ve seen here on Hackaday. Even the control system used for the test flight looks like a modified Radio Control Transmitter. The motors are outrunner brushless motors. Props are carbon fiber. We’re hoping the control system is a bit more evolved (and redundant) than the systems used in R/C quads though. Just like in smaller scale models, batteries are still the limiting factor. The VC200 will only fly for about 20 minutes on a charge. However, e-volo says that new technology should allow it to extend that time to around an hour. Not very much for a cross country flight, but plenty to pioneer a new type of aircraft. Where do we sign for the beta program?

Zero Day has an interview with German researchers who have found a way to take down the Storm Worm botnet. Their program, Stormfucker, takes advantage of flaws in Storm’s command network: Nodes that are NAT‘d only use a four-byte XOR challenge. Nodes that aren’t NAT’d are only using a trivial 64bit RSA signature. Their solution can clean infected machines and also distribute to other nodes. Unfortunately, installing software without the user’s consent is the exact same behavior as malware. Don’t expect to see this in any sort of widespread use. The researchers did point out that some ISPs have moved to shutting off service for infected customers until their machines are cleaned.
