Ok hackers, it is time to show what you are made of. [Michael] has issued a challenge. He is willing to pay for hacked together science tools that meet some accuracy and price requirements. You could win money for doing what most of you are already doing. He needs a few specific things, so go to his site to see what he’s looking for. The goal here is to bring scientific equipment down to a price level that allows a broader audience to access it. Come on guys, it’s for science!
“The Manga Guide to Electricity”, part of “The Manga Guide” series by No Starch Press, is a novel approach to the old problem of getting over the initial mental block when trying to learn electronics.
We decided to compare this book to another introductory text: “Getting Started in Electronics” by [Forrest M. Mims]. [Mims]‘ book is a handwritten masterpiece of electronic literature. The writing style is friendly and concise, the examples are simple, and the drawings are excellent. It also makes sure to keep the learning process as application based as possible. Unlike other books, it doesn’t bog the reader down with math and theory that is only useful to advanced students. Since its original printing in 1983, [Mims]‘ has become the de facto standard for beginner electronic literature. Read the rest of this entry »
Libelium is holding another Arduino Open Hardware contest. Just create a how-to by April 15th that makes your daily life easier. Prizes include GPS, GPRS, SD, and solar modules designed for the Arduino.
Our own [Anthony Lineberry] has written up his experience participating in the 2008 Malware Challenge as part of his work for Flexilis. The contest involved taking a piece of provided malware, doing a thorough analysis of its behavior, and reporting the results. This wasn’t just to test the chops of the researchers, but also to demonstrate to network/system administrators how they could get into malware analysis themselves.
[Anthony] gives a good overview of how he created his entry (a more detailed PDF is here). First, he unpacked the malware using Ollydbg. Packers are used to obfuscate the actual malware code so that it’s harder for antivirus to pick it up. After taking a good look at the assembly, he executed the code. He used Wireshark to monitor the network traffic and determine what URL the malware was trying to reach. He changed the hostname to point at an IRC server he controlled. Eventually he would be able to issue botnet control commands directly to the malware. We look forward to seeing what next year’s contest will bring.
While doing serious fruitcake research, (no, really) we stumbled across the Great Fruitcake Toss held every January in Colorado. The particular entry above caught our eye. Omega 380 was built by a group of Boeing engineers and currently holds the distance record of 1,420feet. It’s a large compressed air cannon. All pressure is human generated using an exercise bike turning a pump. Apparently the team’s first contest entry was a classic surgical tubing slingshot. It eventually broke down during a very cold year, so they switched to this newer design. You can see more videos on the Operation Fruitcake blog.
Capture the Flag (CTF) is a long running tradition at hacker conventions. It pits teams of security researchers against each other on the same network. Every team gets an identical virtual machine image. The VM has a set of custom written services that are known to be vulnerable. The teams work to secure their image while simultaneously exploiting services on the machines of other teams. A scoring server monitors the match as it progresses and awards points to teams for keeping their services up and also for stealing data from their competitors.
The Chaos Communication Congress in Berlin December 27-30, 2008 will host a CTF competition. Most CTF matches are done head to head in the same room. While 25C3 will have local teams, it will also be wide open for international teams to compete remotely. Remote teams will host their own images on a VPN with the other competitors. Now is a good time to register and familiarize yourself with the scoring system. It will certainly be interesting to see how this competition plays out now that teams that can’t make the trip can still compete.
The Dallas Personal Robotics Group held their semi-annual Roborama contest on Saturday November 22nd in Garland, TX. The DPRG had a table at the recent Austin Makers Faire. Each spring and fall, they hold the Roborama contests for autonomous robots. The spring event has contests for outdoor self-navigating robots. The 2008b contests were designed to test the abilities of indoor robots. Normally held at the Science Place, this year they elected to have the contests at the DPRG warehouse in Garland.
Escape From Berkeley (By Any Non-Petroleum Means Necessary) is an alternative-fueled road rally that starts October 10th and ends October 13th. The rally begins in Berkeley, California, and finishes in Las Vegas, Nevada at the Sahara. Contestants are required to use any fuel other than petroleum, and using only those fuels scavenged “for free” along the way. Fuel cannot be purchased. Judges will present awards for both artistic and technical achievements. If you want to get in on the action, there are a number of ways to participate, from registering your vehicle to volunteering for the event or even sponsoring the route “by the mile” or by landmark.
Congratulations to [John Keppel] for his winning t-shirt design. He wins a Dash Express, an in-car navigation device with both cellular and WiFi data support. It’s running Linux on top of the Openmoko FreeRunner’s hardware platform; yes, [John], we do expect you to hack it. We’ll let all of you know when we plan on putting the shirt into production. Thank you to everyone that entered!
The Trossen Robotics Blog has announced the winners of the “Crabfu challenge”. The challenge, issued by [Crabfu] was to make a robot that was full of character. It didn’t have to have a purpose or be autonomous, it just had to be full of character.
The first place winner, pictured above, won us over when he “blinked” a few moments into his video. Strange how something so simple can add so much life. Read the rest of this entry »
