Hardwarezone.com has a cool article written in 2006 about a setup they made to run two motherboards using the same power supply.
The article goes through all the parts used on the setup and has some cool pictures. To make a system like this all you would have to do is fab some sort of case that has all the ports for both PCs.
Something to check out if you run two systems, why have two cases, supply and fans when you can just plug in one?

This solider in Iraq was shot in the chest with an AK-47 round (which had a good chance of piercing his body armor) and was slowed to a non-lethal speed by his iPod. Wonder if it still worked, lol

No Starch Press has released its newest book Linux Appliance Design. An excerpt from the No Starch site:
"Modern appliances are complex machines with processors, operating systems, and application software. While there are books that will tell you how to run Linux on embedded hardware, and books on how to build a Linux application, Linux Appliance Design is the first book to demonstrate how to merge the two and create a Linux appliance."
It looks like a good mix of hardware and software from the sample chapter Chapter 12: Infrared Remote Control. A CD is also included with the book that contains a “home alarm system” prototype appliance that supports the lessons.
This looks like a cool one to read.

Actressarchives.com is reporting that the car KITT from the famous 1980s action series Knight Rider is now for sale in California. The articles says
"...the red scanner light on the nose glows and makes a humming noise just like the TV version. In addition to the red nose light and humming sound, the car also comes with two working video screens in the dash and green, yellow and red lights labeled, ski mode, rocket boost, micro jam, silent mode, oil slick and eject."
If I were to buy it I would park it right next to Bond's Aston Martin and BMW Z3. Honestly though, I've always wanted to put an lit Eject button in a vehicle just to see people's reactions :-P

This week I got the entire gEDA suite installed on my machine and today I put it though its paces. A throwback to the early circuit days I put together a schematic for a parallel port interface. After the schematic was done I decided to post it here and make a dedicated project for any other quick schematics and circuits I make.
Take a look at the new project and the simple parallel port LED interface.

One of the earliest interfaces to a computer I made was 8 LEDs connected to the parallel port. I wrote a quick QBasic program to do all sorts of patterns like chasing lights, count up or down in binary, alternate flashes, etc. While it wasn't the greatest thing in the world it helped me learn a lot about the parallel port and of course programming.
Today I sat down and gave the full set a programs a run through by making a buffered parallel LED interface. I have posted the schematic for all to take a look at.

A little explanation for those who are new to hardware. The DB25 connects through two 78244 octal buffers to 12 LEDs, 8 for the data port (pins 2-9) and 4 LEDs for the control port (Pins 1, 14, 16, 17). The buffers are there so you don't fry your parallel port. There is also a 10 pin DIP switch to set the input pins of the status port (Pins 15,13-10). This is a simple setup that anyone can build to get started with hardware. I posted the schematic image and the image from PCB after I exported it, ran sch2pcb, auto routed and squished it down (the PCB image isn't very clear)
To learn more about there parallel port take a look at these URLs. Enjoy!

Run two motherboards from one supply
S1axter's Tech Log of Crazy Stuff
I've been saying Apple hit a gold mine with their 
A few weeks ago I found some 16F872 PIC microcontrollers I got a while back as samples from Microchip Semiconductor (about 6 of them). I never did anything with them and decided since I had some free time I would build a pic programmer and start messing around a bit. Well luck would have it that I had (almost) all the parts required for Bob Blick's Classic PIC programmer
