[Shawn McCombs] has been spending some time refining his Xbox 360 rapid fire hack. This time around he’s got a lot more features, many of which we haven’t really seen before.
When we looked at the original project he had added an ATtiny85 which read a potentiometer to set the rapid fire speed for one of the buttons. This time around he’s opened up settings for individual weapons in the game. For instance, if you have a hand-gun and a rifle, you can set different rapid fire rates for each to account for the reload speed for those guns. He patched into the ring of LEDs on the controller in order to indicate which preset is currently chosen. There are three tactile switches on the underside of the controller too. One of them is a reset button which gets you back to your primary weapon and the default rapid fire rate. Settings for each weapon are saved to the EEPROM so you won’t lose them when the controller goes to sleep. Check out [Shawn's] description of the project in the video after the break.
[nickinoki] Made a light show using some amplifiers and an arduino. First he created a microphone circuit based around a LM386 Audio Amplifier. After amplifying the output of the microphone a second time, he uses three bandpass filters to block all but a few desired frequencies from reaching the arduino. By only letting a few frequencies through the arduino is able to determine if the song is louder at higher or lower frequencies. Then using the three analogue inputs he created a scheme for generating the light show on an arduino. While he was unable to achieve the exact target frequencies with his bandpass filters they worked well enough to allow him to successfully generate the light show.
The Israeli hacker [Ehud Tenenbaum], known as “the Analyzer”, was arrested along with 3 Canadians for allegedly hacking into a Calgary-based financial services company and withdrawing almost CDN $2 million. The arrests were the results of a months-long investigation by both the Canadian police and the U.S. Secret Service. In 1998, [Tenenbaum] was accused of hacking into unclassified computer systems owned by NASA, and the Pentagon, among others. He is in custody without bail, although the three other suspects have been released on bond.
We get a lot of email challenging us to hack things. Sometimes we ignore them, other times we send some words of encouragement. But this time around we thought [Tait] had really come up with a great hack; to build a Bluetooth handset into his prosthetic finger. He hasn’t done much hacking in the past and was wondering if we could put out a challenge to our readers to make this happen. After a bit of back-and-forth brainstorming he decided to take on the challenge himself and was met with great success.
Like other Bluetooth handset hacks [Tait] started with a simple ear-mounted module. He extended the volume button with a piece of plastic and placed it under the battery. A couple of wooden matchsticks space the battery just enough so that it can be squeezed to adjust the volume level. He then extended the speaker with some wire. Next, he used the Oogoo recipe from our previous post to mold a false-finger and a thumb-ring. The PCB and battery fit in the finger, which places the microphone near a hole in the pad of the plastic pinky. The thumb ring houses the speaker to finish the look. Don’t miss the photos [Tait] sent in after the break.
The completed prototype can still be recharged:
And it fits like a glove:
Originally he told us this hack was above his skill level. Well congratulations… looks like your hacking skills just moved up a few notches!
Because his computer is gradually turning into an all-inclusive media display device, [Shawn] figured a remote to control the volume and a video playlist would be a reasonable addition. TV remotes for computers have been around for years, but [Shawn] decided to go the DIY route and build his own computer remote.
For the build, [Shawn] used a Teensy dev board with an IR receiver module and the requisite infrared remote library. To translate infrared signals to keyboard commands,[Shawn] decided to base his project off a previous build that used a small program called AutoHotKey.
Right now the build can cycle through a pre-defined YouTube and Shoutcast playlist and change the volume of the currently playing track. There’s also support for moving the mouse with directional buttons on the remote, but we’re wondering if a better implementation would be using the Windows multimedia keyboard scan codes that should be supported by [Shawn]‘s laptop.
Still, [Shawn] managed a very nice build that would fit into our computer battlestations quite nicely. Check out the demo of the remote in action after the break.
