[CyberPyrot] and [l0rdnic0] released their spitfire mod on acidmods for XBox 360 controllers. It involves some fine wiring, but a relatively low parts count. The heart of the mod is a PIC16F84A, a crystal for the clock and a few passive parts. It took me a little while to find it, but the code for the pic hiding under the parts list. For a lengthy demo of the mod in action, you can check out this video.

[bunnie] just happened to be at the Embedded Systems Conference in San Jose on exactly the right day to witness the live teardown of a Sony XEL-1 OLED TV. The XEL-1 is Sony’s flagship OLED panel that’s only 3mm thick… and $2500 for just an 11-inch screen. [bunnie] was able to take quite a few shots of the components as they were passed around. He pointed out a few interesting bits about the construction. There seems to be quite a bit of thermal material on the display to prevent “avalanche thermal failures” (which I’m guessing doesn’t look as cool as it sounds). OLED displays are completely transparent and their legendary contrast ratio is just a result of the dark backing material. The mainboard seems to be a bit of overkill for this TV and [bunnie] concludes that it’s just the standard image engine architecture from Sony’s Bravia line put into a smaller package.
[rustlabs] put together an interesting looking gaming gun for FPS games. He wrote up his build and how to use a webcam to provide gun tracking for games like Half Life 2. He gutted a keyboard to provide the button interface, and infrared LEDs on the gun body are tracked by the cam. Surprisingly, no USB game pads were sacrificed in the build, just a USB keyboard and mouse.
[qDot]’s been spending alot of time with the Novint Falcon haptic controller. He’s put together a ‘brain dump’ of everything he know about the device – and some notes on his efforts to put together his own software library for the thing. I’m definitely interested in the parallel robotics platform that it appears to be based on.
[Daniel] sent in his Nixie tube VU meter. It uses 14 Russian IN-13 Nixie bar-graph tubes. He built a custom circuit to amplify, filter, smooth and feed a voltage divider to assign signal levels to segments and finally some high voltage transistors to drive the tubes. The circuit looks pretty big, but it’s repeated for each tube – so he worked hard to keep the cost down as much as possible. Now this just needs to live on the front of a massive tube amplifier.
Remember [John]’s Halloween laser tracking game? He’s been busy since then. After building his own version of multi-player missile command based on his laser interaction game, he added head tracking (using the same method as [Johnny Lee] . Check out the video after the break, and grab the full source for Mac or Linux.
[Shadow] sent in this handy idea. For many, it’s sort of a captain obvious hack, but I’m hoping that this might keep a few of these things out of the trash. He needed to send video around the house from a media PC, and happened to have an old XBox RF modulator sitting around. He popped it apart and located the audio and composite video inputs. To get the signal to the rest of the house, he plans on installing a distribution amplifier that’ll amplify and split the signal to each TV set.
