Dance of the… (construction) cranes

Hacking is all about using parts and resources in an unconventional way. If stringing a pair of high-rise cranes with LED Christmas lights and making them move to a piece of classical music isn’t unconventional, then we don’t know what is. For nearly a quarter of every hour last night, 2 crane operators, along with two ‘choreographers’, swung and spun the cranes around in a coordinated fashion. The project was created by [Brandon Vickerd] as part of Nuit Blanche.  Its purpose was to showcase the technology that builds the cities we live in. A live video stream from various viewpoints was projected on site, below the cranes.

A bright way to cycle

Want to be visible when cycling at night? [Neon Dean] came up with this possible solution, which he cruised on at Nuit Blanche. Its a bicycle with neon lights mounted on every surface possible. [Dean], who gave a similar treatment to his car, explained how it worked. All of the tubes take their power from a 12VDC battery he carries in a fanny pack. 12V is a far too low voltage to power the tubes, so a step up transformer is used to bring that number way up. [Dean] also decided to install a neon tube on each wheel. In order to deliver power to them, he mounted a rotor on each wheel, with two conductive tracks running close to the edge of each rotor. Two strips of steel act as brushes (in a manner similar to those on slot cars), and deliver the stepped-up power to the tubes. One creative, but perhaps not so bright, idea is [Dean]’s neon tube helmet.

CN Tower synced with techno

As part of Nuit Blanche, Toronto’s annual community art event, the CN Tower’s lighting system got put to some creative use. Installed 2 years ago, the RGB LED-based system is composed of 1330 individually addressable lights lining the glass elevator shafts. It costs just under $1000 to run almost every evening for a month. Named ‘Bright Lights Big City’ (not to be confused with the book, movie, or song of the same name), this project was coordinated by [Ryan Stec]. The lights on the tallest freestanding structure in North America were animated to CIUT 89.5 FM for the entire night. This innovative solution allowed one to appreciate the light show from almost anywhere in the city with access to a radio.

Toronto embraces 4-letter words

This year was not the first in which the City Hall of Toronto was lit up in a unique way. However, it was the first time that the government building was used to project 4-letter words. Brainchild of [D.A. Therrien], the 4LWM represents something that he imagined for a long time. [Therrien] built the huge sign in Scottsdale, Arizona, where he displayed it over the waterfront. He was later commisioned to bring the sign to Toronto for Nuit Blanche after making some adaptations (due to weather differences). The sign is composed of 4 huge 16-segment displays. Each segment is made of many neon light modules. This configuration makes it less noticable if one such module fails. The sign is controlled below from a computer, which allows it to display text and simple animations. It’s the first in a series of installations dubbed ”Beautiful Light” by [Therrien]. Despite the name, no inappropriate language was displayed on the sign.

Garage door… packet sniffer

Some type of logger or sniffer exists for almost every form of electronic communication. Your keystrokes, phone conversations, and wireless networks could all be monitored. In this awesome proof-of-concept project, [James] expanded that array to include garage door openers. After receiving a piece of chain mail which stated that criminals have the technology to record any remote code and play it back, [James] wondered if he could build such a device that would work on at least his opener model.

Batcave-style entrance (on a budget)

Want to enter your hidden lair in style? Well [Jimmy] simply wanted to create a cool prop for his school’s homecoming dance. This project includes some obvious inspiration from Wayne Manor. [Jimmy] wired up the automated entrance with a 12VDC motor. In order for it to be able to push the door , the motor had to be attached to a gearbox, which directly powered a wheel. Current consumption issues were solved by using a wall-wart. Because a real bookshelf would still be too heavy, [Jimmy] dressed up a regular door with some patterned wallpaper to give it the right look. Coupled with a Shakespearean bust concealing the button, and some other cosmetic touches, this project was sure to impress any student who knew its secret.

PSP Go gets butchered (teardown)

Not due to be released until the beginning of October, a PSP Go demo unit (shipped to G4TV) has already earned itself a teardown from [iFixit]. Among what was discovered:

- Once a few screws are removed, the battery is user replaceable (as-in: no soldering iron required)

- Wireless connectivity is only supplied through a 802.11b chip (no update to ‘n’, or even ‘g’, by Sony)

- Almost all chips are EMI-shielded (making them a bit more annoying to get to)

With a cheaper version of the PS3 ready to hit shelves, one can only wonder whether the relatively high price tag on this new PSP is worth it.

Update: It seems as though no party involved wanted the info leaked this early, which explains why the video and picture gallaries (up courtesy of Google) have been removed.

Update 2: The article (linked above) and video are now available. An explanation on why Sony had them remove the items for quite some time (plus some repair manuals) was posted by iFixit.

Arduino-human synthesizer

(Thanks to [Aaron] for the tip) As a promo for [Calvin Harris], some of the creative minds at Sony Music have put together an Arduino-based sythesizer composed of 15 bikini clad babes. By analyzing which circuits are closed, the Arduino Mega is able to tell a sequencer which sample to play. The only innovation happens to be that the circuits are painted onto the aforementioned girls with a conductive body paint known as Bare.

Developed by students at the Royal College of Art, the paint is not available for purchase, but they are willing to mix a batch up for art installations or performances. Technical stats (such as resistance) have not been released, but for a washable paint it seems to be performing quite well.

How was the whole project set up? The video below reveals all:




Nokia PUSH competition

With the upcoming release of a Cortex-A8 based handset, Nokia is looking at gaining some popularity with the hacker crowd through their new project/competition. If you can think of a good hack for the Maemo-running Nokia N900, you could win a vague prize pack consisting of the device itself, plus support (including financial) to make your idea a reality. The website states that winning hacks will be toured around the world. The due date for submissions is October 11th. A getting started guide is available (though it mostly consist of instructions on connecting the N900 to an Arduino through bluetooth).

Wireless RGB light bulb

Want to make the above yourself? [Sprite_tm] did a thorough job documenting the build step by step (complete with pics, schematics, graphs, and links to the parts used). In summary, [Sprite_tm] busted open an Ikea CFL bulb to reuse the housing. Inside, he installed a scavenged power supply, ATtiny44, RGB LED module, and a radio receiver. A remote control allows [Sprite_tm] to change the lighting of his room to nearly any color. The cost of the project is a little under $30. The price tag isn’t so steep when one considers the insanely long lifetime of LEDs.
