This portable Atari is the result of [Mario’s] toils. The core system is an Atari Flashback 2, an embedded system released in 2005 with several built-in games. The stock titles weren’t enough so [Mario] added a cartridge slot in order to play whichever games he wishes. The case was originally the packaging for an iPod touch so you know it’s sturdy. We also like the free-formed audio amplifier as seen in the work log. Does anyone know if the Flashback 2 has a pause feature?

We love it when footage of a robot prompts a “holy crap” response from us. This little guy, a product of the Chiba Institute of Technology, uses four rods as a suspension system for jumping. The bulk of the bot can be moved up or down, using its momentum to raise the wheels and jump to the next level. Check out the clip after the break to see how getting down involves a controlled fall as graceful as a dancer. Doctor Light better get cracking on another robot to take this one out when it turns on us.

[Peter’s] been hard at work designing an affordable Selective Laser Sintering (SLS) 3D printing platform. We first saw his work on this back in April when he was working mostly with acrylic. Now he’s moved on to a design that relies on hardboard which has resulted in a build that comes it at around $20 including the motors.
The design uses a dual z-axis table for the feed stage and the build stage. That is to say, as the powder is fused together by the laser the platform it is on is lowered. Next to this platform, the feed platform is raised, allowing the power to be swept onto the build stage. This setup is moving in the right direction, but we’re still waiting to see what works when it comes to adding the laser and sourcing the powder.
[_coreDump] was doing some database vulnerability testing using SQLmap to automate the process. To his dismay, the package was unable to test using the Simple Object Access Protocol. Faced with having to manually test all of the SOAP vulnerabilities he decided to work some Python magic and add support. His solution allows SQLmap 0.8 to parses XML data from the SOAP protocol by modifying three files from the package. He’s made the diff files available if you need this functionality for your own security testing.
If your soldering skills are up to snuff you can add a motion control feature to your radio controlled transmitter. [Starlino] used a combination accelerometer and gyroscope module as an alternate source of analog control information. He built a filter to dial in the analog voltage range to match that of one of the sticks on the controller. A switch is used to disconnect the signal when motion input is not desired. This would be a nice addition to one of those more creative aerial hacks.
Satisfy your need to view some quality machining by looking through this Stirling engine worklog. We’ve seen these engines used a few other times in creating electricity from solar energy, powering a car, and even built from aluminum cans. [David Morrow] built this rendition to push the limits of his machining skills. We’d say he succeeded. The finished piece should run with the help of a heat source such as a candle. There’s no video of this engine, but we’ve embedded a clip of a similar device after the break in order to give you an idea of how this would work.
[Geordy] added a serial port to his Zipit. It uses a 3.5mm jack as the connector. He managed to include an RS232 level converter inside the case. Both components were hard to fit into the cramped quarters but he did it and he kept the hacker-friendly device looking nice too.
