[Alan] noticed that his external hard drive was getting quite hot to the touch after a few hours. He says that it was probably designed to handle the heat sufficiently, he thought it would be fun to beef it up. He’s using a pic 12f675 microcontroller as the brain and an LM35 temperature sensor. The Fan speed is varried in 8 steps from 35 degrees C to 45 degrees C.
As we posted about [Atarity]’s XBMC hiding in an SNES controller, we were finishing work on a tutorial for [Adafruit]. The tutorial combines a Teensy USB development board with a 3D accelerometer inside of an SNES controller. The Teensy is programmed to poll the SNES controller buttons and read the accelerometer values. The buttons are set to keystrokes and mouse buttons, and the accelerometer values are processed into mouse movement. Programmed to play Portal, we created a video showing how to use the device. You can see it after the break.
It was not quite as easy or quick as the typical PC gamer left hand: WASD, right hand: mouse stance. However, we can think of a number of other games that could be improved with the use of a device that, with a bit of hacking, could time keystrokes as the user needed. With a bit more hacking, the device could be made to brute-force passwords. What else would you do with this?
Its been quite a while since we’ve featured something from iFixit. But when we saw they had torn apart the next greatest Apple product, the iPad – released today, and how everyone on our team loves it, we thought why not also let our user base enjoy the destruction informative teardown as well.
In both the original and the FCC teardown, we see some awesome features and tricks Apple implemented. Most notably the two separate 3.75V lithium polymer cells, not soldered to the motherboard, allowing users to easily replace the battery if need be. However, in the opposite respect, more components than ever are being epoxied to the board, making the iPad much more rugged.
We’re left wondering, with everyone able to see the beautiful insides, does it change anyone’s mind on getting an iPad? Or would you rather make your own?
This one could be a game changer. [Chris Harrison] and a team of researchers are showing off a method of using your arm as an input device. An arm band worn by the user picks up acoustic signatures created by tapping on your arm with the other hand, or taping your fingers and thumb together on the same hand. They’re achieving accuracies in the 82-97% range but it gets even better. Take a look at the video after the break and see what they’ve done by adding a pico-projector to the arm band in order to use your arm or hand as a touch display.
We liked seeing the concept mice from October, but the future of input devices might already be attached at the elbow.
Here’s another SNES controller converted to house a USB system. The one we saw last time used a kit as an adapter for the controller but this version uses a home-built PCB and an ATmega8 microcontroller with the latest revision of an open source adapter for NES and SNES controllers. As you can see after the break, [Atarity] built the adapter, then added it along with a USB hub and thumb drive so that he could run a copy of XBMC from the controller. Now he’s got XBMC as a way to launch emulators for those classic games, as well as play traditional media.
You will be seeing more of this type of mod soon. We were tipped off that an in-depth tutorial for SNES controller hacking is on its way, although that is unrelated to [Atarity’s] work.

[Daniel] wrote in to show us the project his group has been working on. It is a massive display wall consisting of 28 projectors and 30 computers. With a resolution of 7168×3072, viewing a 13.3 gigapixel image is a treat. That treat is made even stronger by the fact that navigating the image is done multitouch style with a touchless system built from web cams. We’ve seen lots of projects come out of the NUI group with similar interfaces, but none that used the webcams like this. Usually, the webcam is detecting some kind of interaction between the person and an infra red light source. Maybe that is happening here and we just don’t see it.
[Viktor], one of our favorite avid hackers, has been playing around with 1-wire systems all this month. What started out as a MicroLAN Fonera has turned into an iButton interface, to a 1-wire powered hub, and finally a 1-wire character driven LCD. Anyone looking at 1-wire systems or OWFS could surely benefit from his testing.
However, if you still haven’t gotten your fill of 1-wire goodness, let us remind you of the 1-wire HVAC and IPv6 to 1-wire protocol translator.
[Thanks Juan]
