Six Monitors, One Video Card

6 displays 1 videocard

With most of us utilizing at least two monitors these days in our day to day operations, six monitors, while an awesome thought, might seem a little too excessive. After all, do we really have space for multiple video cards?

AMD has a new setup in their testing lab that is running six Dell 30inch displays at 7680×3200 through a video card holding six DisplayPort connectors.

Maximum PC has the scoop on the setup, and they say that this single GPU will be coming out on AMD’s DirectX 11 capable chips. Details are slim with the amount of video RAM, speeds and cost not known at present.

Think of the possibilities! Trade shows are one thing, but how about a video wall at home for gaming and movies? How would you use the six monitors shown above? Be sure to leave your ideas in the comments.

Nixie Plasma Ball

This one came out over a year ago and we missed it. [Daqq] has made a plasma ball out of a nixie tube. All that was required was the transformer from a cold cathode meant for computers and a nixie tube. He did have to do a tiny bit of modification to the power supply, which you can see on the project page. This isn’t the most useful project, since you can’t really see much of the plasma, but it is really cool nonetheless. We think this would make a really neat button. You can see a video of it in action after the break.

Classy Hard Drive Speaker Set

Hard drive speakers aren’t anything new, but they have yet to be done very professionally. Most hard drive speaker hacks are awesome, but aren’t meant to be a showpiece. [Oliver] took the opportunity to put together a set of 20GB drives and a custom-built acrylic case with a horizontal VU meter up front. The project is well-photographed and documented and can be recreated without the use of laser cutters or other expensive tools. The only thing it’s missing is an iPod dock!

Tube Amplifier In A PSU

[Niclas] sent us his home made tube amplifier. For the case he used a computer power supply unit, took out the guts and replaced them with the amplifier board. He based this build off of an existing design but took a more minimalist approach. The wooden face plate has an on/off switch, an audio jack, and volume control. Apparently, the tubes are floating loose inside of the case. We’d recommend a more secure mounting method for these delicate parts.

Controlling An R/C Car With A Pic16F84

[GuySoft] sent in this project. He doesn’t normally mess with electronics, but decided to give it a try. He chose a fairly complicated project to be his first, but seems extremely comfortable with it. This project was to control his R/C car with a pic16f84. That chip was chosen simply because it was the only one available at local stores. Though we’ve seen much more complicated projects in the past, he does a great job of showing exactly what has been done. He shares his thoughts and source code with us as well. He has express a little frustration about the closed source compiler he was using, so if anyone has any suggestions for him, he would probably appreciate it. The funny part is that he mentions that people would just tell him to “get an AVR”. We think the readers here will probably be happy with how he pulled it off.

Rock Band Drum Set Remake

We’ve seen some impressive mods for the popular video game Rock Band, from new cymbals to an air powered kick pedal, but we cant say we’ve seen someone go as far as the folks over at EDrums. They start off making their own mesh heads, a junction box to connect everything, and then a base to hold it all together. It is definitely some dedication and hard work for a setup that will only be used in the living room in front of the T.V. Check out some more video of it in action, and a comparison to the original Rock Band drum set, after the break.

Uzebox Video Player

Everyone’s favorite open source game console, the Uzebox (also cloned as the Fuzebox), just got a new feature hacked into it – a video player. At reduced quality (8-bit color), the Uzebox was able to play ‘The Matrix’ off an SD card @ 30fps plus the audio @15kHz. That’s a pretty impressive feat when one considers it is running on 4096 bytes of RAM. The video file had to first be converted into a series of pictures through a Photoshop macro in order to be playable. A Uzebox can be built with little more than a few resistors in addition to an overclocked ATmega644P, and AD725 (which has been skirted in certain incarnations).
