After moving twice this summer, I finally got my workbench set up again (at least enough to start building stuff again). So I was able to build the latest version of the LCD ARM dev board (http://dorkbotpdx.org/blog/scott_d/arm_lcd_development_board). It works fine and I think all the errors from the previous version are fixed. So I've attached the Eagle files and the BOM. There is a spreadsheet version of the BOM which has pointers to purchase the various parts and a text BOM which has the part locators for the Eagle board layout as well as the values for the jellybean parts.
Several months ago, I was approached by the Portland band Starfucker (STRFKR) to build them an LED video wall for their upcoming tour. It needed to be large, bright, and durable, but also lightweight, portable, and easy to set up and tear down. They wanted to be able to plug in an iPod or iPad and play videos that are synced up along with their click track so everything goes along perfectly with the music. I enlisted the help of Alex Norman to take care of the software side of the project, and got to work trying to figure this thing out. It seemed like it could be made with mostly off-the-shelf components, and indeed that turned out to be the case. We decided that we would open-source the entire project, for the good of all mankind.
Anyone going to be in New York for the World Maker Faire? I would love to get you in for free if you mind hanging out in my booth for a couple of hours.... I'm kinda worried how busy its going to bee..... Feel free to bring a cool project to show off too!
I built a small battery-powered amplifier today.
I partially wanted to test the tindie waters and support the cause (since it's such a great idea), but I also figured I could kill two additional birds with this buy-build-a-kit-stone:
I bricked my long-running Seagate Dockstar a few weeks ago, but it was OK because I had already transferred its duties to a beefier GuruPlug. However, I hate having dead hardware lying around, especially when I can fix it.
I'd like to be help out at the pdx dorkbot booth... who's putting this together?

Recently I posted about the ARM based LCD development board I showed at a Monday DorkbotPDX meeting. At that time, I was waiting for another revision of the board before releasing the Eagle files. I got the next version back and it looks OK so I've attached the files.
The firmware source code is available on GitHub.
