I have a Mac Mini so basically I have an adapter from mini DVI to a VGA, then I have the VGA splitter running from the adapter to the two screens. One of my “monitors” is my 32′ TV that is hanging on my wall. I use the computer as my DVD player so its nice to not have to keep connection one screen up then unhooking to hook the other up. Now they both show the same view. The splitter works great. Only problem I seem to have is on my actual monitor (21.5″) at times when there are darker colors on a web page, the colors seem to be scrolling down. This can be very annoying. I’m not sure why this only happens at times, but it never happens on my actual TV. Besides that, this product works great.

Sorry, too lazy to read orig article on iPhone right now

And I need an external mouse… so yeah.

It was to power a Xircom parallel port ethernet adapter.

A while back, I rescued a number of such devices, for grins, from otherwise being ground up, compacted, and sent to Africa or something. They make great little enclosures…but I’m going to hold on to one or two of them in case I ever need quick ethernet access to a junky old box.

I’ve had a bad mic fry the mic input on my motherboard (Just after I could have returned the board!), so in general I’m wary of doing something like this unless I know it’s safe… I’m far more likely to take a couple few minutes to build a +5v regulated power supply with a USB port output. But that’s just the geek in me. :P

Though I still use both in tandem for dual monitors.

I’ve been coming to this site for YEARS, and I am glad that my random act of boredom actually resulted in something useful. :)

I posted on the INSTRUCTABLES site that there will be a newer version in the next week or so that has protection on it, just in case.

Also, just for giggles, different colors of rubberized coating.

Thanx!!!

Awesome idea.

Good thinking!

The vga/dvi/hdmi uses the power pin along with ground and two i2c pins for communication. That i2c channel can be tapped. On some linux and macs, you can use the i2c yourself, but you need the correct settings.
