If this sort of topic is up your alley (community and spam management, harassment and abuse issues, etc), I highly recommend Sarah Jeong's recent book The Internet of Garbage. It's a very quick read, and a great summary of the state of spam and abuse management in online communities today, and thoughts on the future.

Just a note: this appears to not actually be an 802.3af power source, but rather a passive supply.
So, if your project actually requires real negotiated 802.3af (some embedded boards, some routers, etc), you may want to check that this will work for you. -
$19.94?! I'm quite certain I saw this just last week on DealExtreme for only $9.95. Save your money, people!

Just FYI: it looks like all the images in this tutorial are throwing "Forbidden" errors.

Just FYI: the images (when you click on them) are no bigger than the thumbnails. The images on the 5V/16MHz board product page look right, though.

I'll have to second a few other comments here: the 10k/10k divider on the RX lines had me pulling my hair out for a little while with a touchy SD card (one card worked, even though 2.5V was out of spec, but another card didn't). Suggestion for a future revision: use FETs for all four lanes. Now, you've got a four-port bi-directional level shifter.
Good example (but skip the voltage regulator):

I think what you're seeing is a function of community size and involvement; the hobby electronics community, and particularly the "open" community, is significantly larger that the organized open community of physical makers. Low-cost 3D printing and CNC tools are improving that, but it's still an emerging community.
From looking through the OpenHardwareSummit website and forum, I don't think the lack of attention to physical makers (vs. electronics) is an intentional snub; it's just a natural bias of the experiences of those who've chosen to make themselves involved in the process. If you work on electronics all day, you might not feel as though you're in a position to speak about the particular needs of the 3D printing community, for example. -
Awesomesauce. I threw in my $5 on a whim, hoping it would be something at least worthy of tuning into a wall ornament. ;-)
I was definitely not expecting a high altitude sensing board! It powers up just fine, and interacting with it via serial suggests that at least a few of the sensors are just fine (apparently, I need to run my humidifier a little more). :)
Awesome. You guys just made my day. -
My kingdom for one of these! :) Apparently a breakout was sold for this at one point in Europe, ready-to-go for breadboard use:
