While researching the CHDK How-To, we came across the team’s instructions for porting the firmware to entirely new cameras. In theory, CHDK should work on any Canon running the DIGIC II or III processor since most of them are running the same VxWorks OS. A dump of the camera’s firmware is required before porting work can begin. On some cameras, the firmware was retrieved using software, but others required a hardware route. Pictured above is a Canon A610 that’s slowly flashing out every bit of its firmware using the built in LED. The photodiode is hooked up to a soundcard where the entire bitstream is recorded. It takes 1-7 hours to read the entire firmware. Once the sound file has been captured, it’s reverted to the original bytes and can then be decompiled with something like IDApro.
Since it happens to be the day after a nice holiday break, many of us are finding ourselves back in front of our desk once again. Perhaps some of you never left it the entire weekend. In any case, it seems fitting to take a look at a few interesting integrated desks we’ve come across lately. Follow through after the break to see our favorites.
A new legal precedent may be set with the case of [Lori Drew], the St. Louis woman who posed as a teenage boy on MySpace and harassed 13-year-old [Megan Meier] until she committed suicide. Drew is being charged under the computer fraud and abuse act, on the grounds that she violated the terms of service agreement of MySpace. If she is convicted of these charges (she is also being charged with conspiracy), it may allow for the criminal prosecution of anyone who violates the terms of service agreement of a site under the same law.
Not even a week ago we asked what we should do with our OLPC XO. InformIT’s [Seth Fogie] has written a great two part article that covers turning it into a hacker toolkit. Part one is an overview of the OLPC, how to upgrade it, and do some usability tweaks. Part two covers installing Nessus, Metasploit, and doing some wireless sniffing. We’ll be building our own little green monster based on this and let you know how it goes.
As anyone who has lusted over the technical specifications for Canon’s new Digital Rebel XSi knows, the capabilities of the average point and shoot camera are severely limited. Using the CHDK firmware hack, the features of Canon point and shoot cameras can be significantly expanded, allowing for ultra-high speed photography, very long exposures, time lapse photography, and RAW capture. This How-To provides a guide to our experiences using the CHDK firmware, and shows just how easy it is to get more out of a point and shoot than ever thought possible.
[Jerome] sent in this awesome Muffin maker (yes, muffins) that [Carl Boucher] and [Dominic Dussault] built for [Carl]’s final project in his Industrial Electrical Technician program. No real technical details, just some tasty inspiration. If you prefer cookies, you might want to check out fabbing with Nutella.
