[Pocket Lucho], the builder of mini arcade cabinets, is back with another build. This time it’s a miniature Neo Geo arcade machine (translated). The build is very compact and neat. He attached the control panel and the PS one display using magnets to make the wiring more accessible. It has video out and second player input too. You’ll find an assembly video embedded below along with a trial run. Read the rest of this entry »
The folks at SparkFun were startled by how small USB bluetooth adapters had become so they split one open. They noted a few interesting design features. It has a small folded trace antenna on the board edge. The metal USB housing acts as the RF shield. The bluetooth IC is an AS3620QA. Now we wonder what those tiny Buffalo drives look like inside.
The latest Inventgeek project is a 12 outlet control box. They decided to demo it using a giant bulb based VU meter. The control box has 12 individual outlets hooked up to two layers of six solid state relays. [Jared] notes that SSRs can be very expensive, but he purchased his on eBay for ~$10 each. Wiring and installation on this project is incredibly clean and they plan on using the control box for future how-tos. The simple audio circuit used for the VU is based on the LM3915. You’ll find full plans on the site or you can watch the overview video embedded below.
[Shachar Geiger] sent in an interesting project that he worked on with [Tal Avivi] at the Bezalel academy in Jerusalem. They were given the task of designing a 1-person electrical urban vehicle. They took some cues from MIT’s Transology and designed the OmniDirectional Research Platform (ODRi). There’s a video of it embedded above. It can be driven using three different input styles: an accelerometer joystick, a traditional gamepad, or body mass shift. They started with an Arduino, but needed more I/O and had to switch to a Wiring board (this was before the Mega). The platform is built mostly from scrap. The accelerometers were placed in an old Microsoft Sidwinder. The standard joystick is from a Sega Mega Drive. The weight sensors are out of cheap home scales.

A little over a year ago [Ian Lesnet] joined our hacking team and began cranking out some of the best original how-tos Hack a Day has ever offered. You may remember our popular web server on a business card from last fall and we’re sure everyone is familiar with the Bus Pirate (yes, they’re still on schedule).
It’s a year later and he’s found himself with less time to contribute. [Ian] is stepping down from blogging at Hack a Day, but you’ll find him right where he started: in the comments. You can also reach him directly on whereisian.com. [Ian] will be continuing to develop the Bus Pirate. You’ll find the latest info on the Bus Pirate’s Google Code page. He’s also posted a guide to the on-board pull-up resistors as well as a self-test guide that uses the new v2.0 firmware to confirm your Bus Pirate is working.
[Ian]‘s contributions will be greatly missed. We’re always excited when we add contributors of his caliber to our crew.
For day two of Black Hat, we sat in on on [Joe Grand], [Jacob Appelbaum], and [Chris Tarnovsky]‘s study of the electronic parking meter industry. They decided to study parking meters because they are available everywhere, but rarely considered from a security perspective.
Update: The video of [Moxie]‘s presentation is now online.
[Moxie Marlinspike] appeared on our radar back in February when he showed sslstrip at Black Hat DC. It was an amazing piece of software that could hijack and rewrite all SSL connections. The differences between a legitimate site and the hijacked ones were very hard to notice. He recently stumbled across something thing that makes the attack even more effective.
The 2009 edition of the Black Hat security conference in Las Vegas has just begun. The first interesting talk we saw was [Andrea Barisani] and [Daniele Bianco]‘s Sniff Keystrokes With Lasers/Voltmeters. They presented two methods for Tempest style eavesdropping of keyboards.
