[Jesse] sent in this beautiful 300 watt amp project. It uses six LM3886 amps to create a pair of 150 watt amps that are bridged to create a single 300 watt amplifier. Usually I don’t mind my lack of multi-language ability, but many of the parts were sourced from this site. It looks like the cases were bought in Hong Kong, anybody know were I could get some in the US?

Movie Screen Mask Controller

I was looking for some ideas for one of my little projects, and I ran across this screen mask controller that [Danny] was working on a while back. The roller drops a mask down, and an optical encoder lets the controller know the position of the mask. The final version is supposed to support ethernet, but I couldn’t find any updates on the project.
XBox 360 Hacking 101 Extra

[BlueMoon] let me know about a translation of an interview posted over at xbox-scene. The original dutch version is here. It’s a very good overview of XBox 360 security and the exploits needed to take advantage of the hardware.
If you dig EVs, you might want to check out my latest experiment. I’ll be building a EV, but each step of the process will be defined by reader votes. It’s $1/vote, with the idea that the votes will pay for the project.
[Jay] sent in a little info on streaming audio and sometimes video to your Wii.
[Robert] sent in his research on building and testing diy GSM antennas for extending rage range.
Solderless Aux In For Bose Sound Dock, Etc
This little how-to was sent in by [Ed]. The sound dock posts get quite a few hits, so I figured I’d share.
There is a solderless way to hack an aux input for the Sounddock.
(1)Go to Wal-mart (or elsewhere) and buy the Griffin Dock Adapter for iPod Shuffle (~$20) and a Belkin Speaker and Headphone splitter (~$4). (The Belkin splitter is needed in order to fit properly over the Shuffle plug on the device, but other cables/adapters might work.)
(2)Remove the existing adapter plate and replace it with the Dock adapter.
(3) Set the switch to speaker. (Very Important!) (4)Plug in one end of the Belkin adapter and you are ready to go! Any input signal automatically activates the Sounddock. Now you have a fully functional female and male stereo headphone input for your Sounddock.
–>Total cost ~$25 and no soldering required.
Biopong

[Teckjunkie] was inspired by Hack-A-Day to build a bio-interfaced game. He modified a thinkgeek pong kit with an Analog Devices instrumentation amplifier and differential electrodes to create biopong. Flexing either arm actuates the inputs on the pong game. (Now you can just grab some dumbells and get a pong workout.)
Hack-A-Day inspired projects are always welcome to the tips line.
Powerglove Wiimote

How, oh how did I miss this one? (original) A japanese hacker merged a powerglove with a wiimote. Need I say more? Seriously, who didn’t want a powerglove when they came out? video of the thing in action is after the break.
Quick extra:
It turns out that the Wii Nunchuck is a great source for parts. It’s got a 3-axis accelerometer, joystick and buttons for a mere $20 [chad]’s wrote a full how-to on turning a wii controller into a bluetooth transmitter and an interface for the wii nunchuck for the Arduino.

Aux Stereo Receiver Controls

[Bob van loosen] added a remote learning circuit made from a PIC 16F84A to his Onkyo receiver – which happens to have remote buttons and a ttl control link for external devices. The PIC listens to the remote link on the receiver. By grounding a pin, it will learn the next remote command that’s received. In this case, he uses it to swap the left/right front/rear signals to gain proper speaker orientation when he switches between his TV and Computer. This would make an entertaining external dongle if you combined it with a smoke generator…
