Laughing Man in Processing

laughing_man

The Laughing Man is the antagonist from the anime series Ghost in the Shell: Stand Alone Complex. During each of his public appearances in the series he manages to hack all video feeds/cyborg eyes in the vicinity to obscure his face with the logo above.

[Ben Kurtz] had been watching the series recently and realized he could put together a similar effect using Processing. The interesting bit, and what makes this more fun than a simple demo, is that he’s using the OpenCV library. OpenCV is a open source computer vision library. [Ben] uses it to handle the facial recognition in Processing and then apply the image.

It’s only 100 lines and we wonder what other fun tricks could be employed. Here’s a Hack a Day skull you can swap in for the logo.

SNES cartridge wallet

nes_wallet

[gamemaster87] put together this SNES wallet. It isn’t just a wallet, it also has internal lighting and theme music. He harvested LEDs from Christmas lights, switches and battery compartments from an old all in one joystick, and the sounds from a holiday card. There’s a Plexiglas window to show off his ID and a belt clip, because you wouldn’t want this thing in your back pocket. Match this up with the SNES clock, NES bike tail light, and the NES security system and you’ll be the king of the nintendorks.

Home made Macintosh for under $240

msiosx1
[Steve] sent in this great step by step writeup on how to load Macintosh OSX onto an MSI wind. The MSI wind can be found pretty cheap, roughly $140. It has a 1.2Ghz Atom processor, SATA, and 6 USB ports. Its a pretty decent system for the price. Add a hard drive, DVD ROM and some RAM and you ‘ve got a complete system. You might have to update the bios to install the new operating system, there are more details about that on in the writeup. The only real drawback is that you have to run the USB in 12mbps mode instead of 480mbps.

There are lots of little tips to keep you from hitting roadblocks, so follow the steps closely or you’ll have to redo it. Since downloading the modified version of OSX is probably illegal, [steve] suggests that you go buy a copy of OSX just to try to balance it out.

Refillable CO2 cartridges

co2

For those who use these little cartridges, you know how quickly the price can add up.  [steve] takes us through the process of adding a valve to a spent cartridge so it can be refilled. Over all, it doesn’t seem too difficult, and [steve] offers lots of tips to increase longevity and reliability. It isn’t very often that we show a hack here that doesn’t involve some kind of electronics, so take a break from the resistors and microprocessors for a moment and enjoy.

[thanks Wolf]

Quick robotic base for netbook

robot_base

This is a great example of how marketing should be done. TeleToyland and RoboRealm(currently down) have teamed up together to show you how to build a quick and easy robot base for your netbook. The build process is fairly in depth, including part numbers and links to various places to buy them. They are using RoboRealm software to control the robot, utilizing two web cams for sensory input.  This should get you well on your way to having an autonomous netbook wandering around your house.

Jacob’s Ladder

jacobs_ladder

[jandgse812] shows us how to build a Jacob’s Ladder from mostly household parts.   The bulk of the instructions for this project are included in the downloadable document, there is a downloadable video as well. Be sure to follow to the end where he shows us a much safer and possibly better looking revision. The Jacob’s Ladder has become standard fair for any mad scientists laboratory. If you plan on having a workshop suited for world domination, it absolutely must have one of these in it. Be careful though, the high voltage can be deadly.

25C3: Nokia exploit stops all inbound SMS

nokia

[Tobias Engel] released a serious Nokia vulnerability today. By using a specially crafted SMS message, you can block the recipient from getting any future SMS messages. The attacker changes their Protocol Identifier to “Internet Electronic Mail” and then uses any email address 32 characters or more in their message. The recipient will receive no indication that they got the message and no other messages will be allowed until the phone is factory reset. You can see a demo video here. This affects many different varieties of S60 phones and no fix is known.

[Thanks fh]
