The main use-case of the device is to help you recover easily from a failed BIOS upgrade (either due to using an incorrect BIOS image, due to power outages during the flashing progress, or whatever). The device only supports SPI chips, as used in recent mainboards (in DIP-8 form factor, or via manual wiring possibly also soldered-in SO-8 variants). It can identify, read, erase, or write the chips.
Of course the whole "toolchain" of software tools I used for creating the hardware is open-source, and the hardware itself (schematics and PCB layouts) are freely released under a Creative Commons license (i.e., it's an "Open Hardware" device). The user-space source code is part of flashrom (GPL, version 2), the schematics and PCB layouts are licensed under the CC-BY-SA 3.0 license and were created using the open-source Kicad EDA suite (GPL, version 2).
The schematics, PCB layouts, and other material is available from gitorious:
$ git clone git://gitorious.org/openbiosprog/openbiosprog-spi.git
You can also download the final Gerber files (ZIP) for viewing them, or sending them to a PCB manufacturer.
Some more design notes:
Basic usage example of the device on Linux (or other OSes supported by flashrom):
$ flashrom -p ft2232_spi:type=2232H,port=A -r backup.bin (reads the current chip contents into a file)

I have put up a lot more photos and information such as the bill of materials, the Kicad settings I used for creating the PCBs, the Gerber files and the Excellon drill files and so on.
The first few prototype boards I ordered at PCB-POOL.COM (but you can use any other PCB manufacturer of course), the bill of materials (BOM) lists the Mouser and CSD electronics part numbers and prices, but you can also buy the stuff elsewhere, of course (Digikey, Farnell, whatever).
I already hand-soldered one or two prototypes and tested the device. Both hardware and software worked fine basically, you just need a small one-liner patch to fix an issue in flashrom, but that should be merged upstream soonish.
In order to make it easy for interested users to get the PCBs I'll probably make them available in the BatchPCB Market Place soonish, so you can easily order them from there (you do still need to solder the components though). Note: I'm not making any money off of this, this is a pure hobby project.
All in all I have to say that this was a really fun little project, and a useful one too. This was my first hardware project using Kicad (I used gEDA/PCB, also an open-source EDA toolsuite, for another small project) and I must say it worked very nicely. I didn't even have to read any manual really, it was all pretty intuitive. Please consider not using Eagle (or other closed-source PCB software) for your next Open Hardware project, there are at least two viable open-source options (Kicad, gEDA/PCB) which both work just fine.
The choice of service was pretty obvious — while Twitter uses proprietary software and has custom Terms of Service, identi.ca is based on software under the GNU Affero General Public License, and the contents are CC-BY 3.0 licensed.
$ git clone git://gitorious.org/laconica/mainline.git
My account details are available under http://identi.ca/uwehermann, where I'm posting smaller announcements and notes about random technical stuff I'm working on (slightly more regularly than in this blog). Sometimes I use the web interface for posting, but using the Jabber integration available at identi.ca is even more convenient. You can both be notified of new posts ("dents") in real time via Jabber, as well as post your own dents from within your Jabber client, which is nice.
identi.ca seems to become more popular every day, which will hopefully make the proprietary Twitter pretty much irrelevant sooner or later.
I found out about TinEye a few minutes ago. It's a nice little search engine which allows you to find exact copies of a photo or even similar versions of it. You can either upload an image for comparison with their database, or point TinEye to a URL of the image you want to check.
The site is also used in Wikipedia for detecting the original source of uploaded images.
I know there is some other website which also allows similarity search of images, but I just can't remember the URL. Please leave a comment if you know of other such sites, thanks!
Even with my humble, and not really widely-known little photoblog, you can already see the Creative Commons license's effects on media sharing and remixing/reusing kick in. Quite a number of my photos have already been used by other people for various different purposes (blogs posts, articles, even album covers), including some of the "bigger" sites such as the Wall Street Journal Blog or Cult of Mac...
Here's the list of places I know of where my photos are used. Please leave a comment if you spot more of them in the wild. I intend to keep this list updated as more of my photos appear elsewhere.
(Oh, and I have no idea why people seem to be so obsessed with my "Sugar" photo...)
You might have already heard of it — the new Nine Inch Nails album "The Slip" has been released by them under the Creative Commons BY-NC-SA 3.0 US license. Yep, that's right, it's totally legal to download it from the web — and use it for any non-commercial purposes!
It's a bit annoying that they want your email address, though. Nothing that bugmenot.com (or similar) cannot fix, but still. Luckily, the files are now also available from archive.org! This, and the fact that the music is CC-licensed allowed me to "play" one of the songs in my Creative Commons music podcast (RSS), and more will likely follow.
