[Duncan Murdock] received a Canon DSLR camera for Christmas and wanted a remote shutter release to go along with it. Since nary a store was open on Christmas, he was pretty much out of luck. Scrounging around in his parts drawer, he found all sorts of goodies waiting to be reused, including a knockoff Wii nunchuck.
He pulled the original cable from the nunchuck and replaced it with an old telephone wire, attaching a 2.5mm plug to the end. The plug goes directly into his camera’s control port, allowing him to trigger the auto focus and shutter mechanisms with the push of a button.
We like the idea of a junk controller being recycled for use in a camera, though we think it has far more potential than being used as a simple wired trigger. If both the nunchuck and camera were fitted with some sort of wireless interface (Bluetooth, IR, etc), we think it would make a great addition to any hobby photographer’s kit.
[Bruno]’s Wii RetroPad Adapter was sent into the tip line, and we’re loving the possibility of using Playstation 2, Genesis, NES and SNES controllers with our Wii.
While there are commercial solutions that connect an NES or SNES controller to a Wii, everything connects to the GameCube port and there is no adapter for Sega or Playstation controllers. For his build, [Bruno] used an ATmega168 to read data from the classic controllers and translate that to the Wiimote I2C bus. Think of it as a new classic controller with the same form factor your 8-year-old self knew and loved.
The schematic for the build is very simple and [Bruno] has all the software out in the open. Even the PCB is single sided and looks like it would be a great candidate for a homebrew PCB. There’s no indication [Bruno] is trying to monetize his creation, so he’s either doing right, or so very wrong. Check out the Dualshock 2/Mario 3 demo of this board after the break.

Not to be outdone by their North American counterparts, these German-speaking hackers have come up with a truly unique console mod. Although modding one system may be OK for most, the builders of this console decided to combine three systems into one clear plastic box. A stripped down Xbox360, Playstation3, and Nintendo Wii were all put together to form this “Extrem” system.
The build style should be very appealing to those interested in video game hardware. Combining the look of a tower PC with a clear plastic allows one to see all components in action. Since the box is lit up with electroluminescent lighting, one is able to show off this system in the day or at night. Continue reading ““Extrem Konsolen Modding””
[Dan] wrote in to share a project he recently finished up, an autonomous Airsoft tank. The toy tank makes use of a wide array of technologies to get the job done, and will stop at nothing to hunt you down (provided you are wearing an IR beacon).
An Arduino board is used to control the tank’s motors, while a Lego NXT module handles most of the other operations. The tank makes its way around using an ultrasonic sensor, which ensures it doesn’t get stuck on any errant furniture or hung up in a corner. While driving around autonomously is well and good, [Dan] upped the ante a bit by making the Airsoft turret completely autonomous as well.
He fitted a Wiimote IR sensor to the tank, successfully interfacing it with the NXT module after a bit of trial and error. Now that things are up and running, he can place his IR beacon anywhere in the room, and the tank will drive around scanning its surroundings until the target is found. Once the tank locks on, a flurry of Airsoft pellets take down whatever stands in its way.
We think that [Dan] did a fantastic job here, but see for yourself in the videos embedded after the break.

Jailbreaking hacks have come and gone for the Wii, ever changing as Nintendo tweaks their software to prevent homebrew from running. Piracy concerns aside, there is a legitimate Wii homebrew scene, and a new, easy to use tool has been released for those looking to give it a try.
Many of the previous jailbreaks relied on bugs found within official Wii games, but there’s a new kid on the block that requires nothing more than an Internet connection and an SD card. LetterBomb is the latest jailbreaking tool, which was created by an individual named [blasty]. It seems incredibly easy to use, requiring little more than entering your Wii’s MAC address into a web form. The site generates a customized jailbreak file, which your run on your Wii via the SD card – that’s all there is to it!
If I had a Wii, I would be hesitant to enter any sort of globally-unique number that could identify my console into a random web site, but perhaps I am being overly paranoid. Either way, it would be great to see an open-source version of this tool released so that jailbreaks could be done offline, without any risk of having your MAC address recorded.
We never really get bored with remote-controlled rovers around here, especially when they involve reusing some old hardware as well as lasers. [Tycoon] wrote in to share his creation, which he has dubbed “Texas Ranger”.
Texas Ranger is built around an old Linksys WRT54GL router, which provides the rover’s WiFi connectivity as well as the serial interface through which everything else is controlled. The rover features a pair of PIC microcontrollers, which handle all of the servo control as well as telemetry calculations.
An onboard camera gives the operator a driver’s seat view of the action, allowing for precise control of the vehicle. Laser triangulation is used to help measure object distance, and a pair of airsoft pellet guns straddle the camera for whenever [Tycoon] feels like making his presence known. One feature we are especially fond of is the pair of Wii nunchucks which the rover uses to monitor its position. Always aware of its operating angle, it auto-adjusts the camera to compensate for uneven surfaces, guaranteeing that [Tycoon] doesn’t have to tilt his head to see straight.
Keep reading to see a quick demo video he shot of Texas Ranger in action.

Medical conditions that prevent individuals from being able to walk are difficult to handle, even more so if the patient happens to be a child. Shriner’s hospitals treat a good number of children suffering from cerebral palsy, spina bifida, or amputations. They are always looking for creative treatment methods, so their Motion Analysis Laboratory looked to some Rice University undergrads for help. They asked the group of engineers to design a system that would make physical therapy a bit more fun, while helping encourage the children along.
The team recently unveiled their project, called the Equiliberator. The game system incorporates a series of five Wii balance boards situated between a pair of pressure-sensitive handrails. The platform communicates with a computer via Bluetooth, registering the patient’s movements as he or she moves along the path. The software portion of the system consists of a monster-slaying game which requires the child to step on a particular section of the pathway to dispose of the oncoming enemies.
The game is designed to get more difficult as the child’s balance and coordination improve, encouraging them with an ever growing bank of points as they progress. The final goal of the project is to enable the pressure sensitive handrails to determine how much the child is relying on them for balance, offering in-game incentives to walk with as little support as possible.
We love seeing hacks like this which not only entertain, but truly help people in the process. Kudos to the team at Rice University – they have done a fantastic job here.
