Serial Hacking With An ATtiny2313

board

[Sprite_tm] automated a portion of serial hacking by sniffing out the baud rate using an ATtiny2313 and FT232 breakout board. The firmware assumes 8 data bits, no parity, and 1 stop bit (8N1). This is pretty much defacto among serial ports so it should work well, though some devices do use different settings. The auto detection routine can sniff rates as low as 110 baud and supports non standard rates. Released under GPLv3, the software is also supplied in hex format.  [Sprite_tm] has provided great project in past such as Working with VFDs, Controllable bristlebot, and AVR boost converter. Additional information regarding serial hacking after the break.

Review: The Manga Guide To Electricity

August 5, 2009 by 377 Comments

title

“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. Continue reading “Review: The Manga Guide To Electricity” →

Yo dawg, we heard you liked accelerometers… Apparently people have been wanting this for a while. We’re not completely sure why, so we’ll wait and see what gets done with it. [Ubiq_01] has connected a WiiMote to his iPhone and is using it to control and OpenGL application. He has released a tutorial (which seems to be down currently) if you want to try to reproduce it yourself.

Introducing ERP: Experimental Robotic Platform. This is an open source, modular robotics platform that, as you can see above, didn’t fair too poorly in the Robogames 2009. [John] has been working on this platform for roughly 2 years and states that it will never be “finished”. It is a development platform, and is always changing and being updated.  You can follow along on the project page to see the major design changes as they happen, such as the wheel suspension system cut from a single piece of plastic. All of the pieces, schematics, and software are available for download. Be sure to scroll down and see ERP’s reaction to some of crabfu’s inventions.

Defcon 17: Badge Hacking

Following up on their post about the new Defcon 17 badges, Wired recently posted some of the best badge hacks of the con. Among the hacks featured were an LED frequency meter hack, a sound seeking dirigible powered by three badges, and a wireless geiger counter random number generator that sent random numbers back to a laptop equipped with a zigbee card. Probably one of the most impressive hacks mentioned, the hack that won the badge hacking contest, was the LED equipped baseball cap modeled above by [Joe Grand], Defcon’s defacto badge designer.

The hacked badge is connected to the cap by an ethernet cable, where the LEDs pulse on and off in order to defeat facial recognition systems. The cap’s designer told Wired that he initially designed the cap in order to sneak into [Grand]’s room to steal the über badges under his protection. Needless to say, the winner doesn’t have to worry about stealing the badges anymore as he was awarded his own über badge at the award ceremony. While we’re not completely sure who pulled off this awesome hack, we congratulate you and all of the participants of the badge hacking contest on your fantastic hacks.

Update: We’ve confirmed that the badge contest winner was in fact [Zoz Brooks], [Grand]’s co-star on the popular Discovery channel  show Prototype This. From all indications, his hack seems to be legitimate and not a clever idea, however we are still looking to confirm this. Also, even though Wired’s article stated that the dirigible was sound seeking, we have confirmed that it is sound avoiding. Thank’s to everyone in the comments for pointing these things out.

Sticky Light

With the availability of webcams and projectors, multitouch and interactive demos have become increasingly popular because they’re so easy. Students at the University of Tokyo took a new approach that uses lasers instead. They created Sticky Light, which uses mirrors, a laser, and a single photodetector. Unlike camera-tracking setups, this system requires no visual processing. The laser moves around and bumps into dark objects, sticking to them. It can follow drawings on the table or objects in space, such as shirt designs. They also created a few basic games and a demo that makes sounds based on the movement of the spots. Video of the project after the break.

Malicious ATM Found At Defcon 17

A fake ATM machine, set to capture ATM information was found at Defcon 17 in vegas this year.  Its design has a tinted plastic window at the top which attendees noticed had a computer in it. It was quickly removed by the police. Is this an amazing coincidence? We doubt it. Someone probably knew exactly who was going to be there and either wanted to scam some hackers or just wanted to have some fun.
