[Vince Briel] has created an embedded device based on the Parallax Propeller chip that acts as a serial terminal. It takes input from a standard PS/2 keyboard and outputs color VGA. It also has a second serial port to connect to a PC for debugging or programming. He is selling kits and has the schematics available. The board has a lot of hacking potential and it could easily be made into a video game or a Wikipedia browser.

[gmgfarrand] needed an extra USB port to power some devices. Since he just needed power, and no data, he slapped together this quick adapter that pulls power from the vga port instead. While we’re not sure if this could possibly damage your video card if you pull too much power from it, we’re happy to see someone being original. That VGA port goes unused so often, this adapter might just make it a tad more useful.

In case you were wondering what industrious hacker [Joe Grand] was doing when he’s not building stuff for Prototype This!, designing Defcon badges, or testifying before congress, it’s this: The BSoDomizer is a VGA pass through device that displays an image of your choice on the victim’s screen. It can do this either periodically or via an IR trigger. The image of choice is a Windows style Blue Screen of Death. It’s powered by a watch battery. The project site has all the schematics you need plus ASCII goatse imagery; you’ve been warned. Embedded below is a demo of the device. We unfortunately didn’t get to see it when it was originally presented during Defcon 16. Read the rest of this entry »

Deogen is a small, self contained device for testing monitors. It was designed back in 2000 to reduce the amount of space and effort required to test monitors in a computer shop. The initial design used an AT90S1200 microcontroller to generate test patterns for the monitors. Being about the size of a portable CD player, it was much easier to take to any monitor and plug in for testing.
Version two of the device, pictured above, is much smaller, being about the width and height of a credit card. The depth is slightly larger than a 9 volt battery. Compared to the last vga test project we ran, this one is tiny. The unit boasts a decent set of features, such as; eight test patterns at four different resolutions, battery or DC power, and small form factor.
The processor of version two is an ATtiny2313 at 20MHz, and controls the H sync and V sync signals directly. The RGB is converted to analog using a resister network. The power circuit is custom made for low power consumption, though they note that a 78L05 equivalent unit could be used in its place.
The plans for the PCB and the software are available from their site. Head on over and check out some pictures of it in action.
