ARDUI
arduino-data-webserver-part-1
Sample Web Server running on the Arduino + Ethernet Shield.
Depending on the url used the Arduino will do something and/or send something back. The code is intentionally simple so you can modify it for your own Ethernet Shield projects. Enjoy!
I have an NKC Ethernet shield, but It uses the standard Arduino Ethernet library, so it should work with the Arduino Ethernet Shield too.

$3 WI
3-wifi-module-part-9-x-10-hacking
Hacked an X-10 remote so I could control high voltage devices via WiFi without involving any high voltage in my circuit.
Yes, I'm aware that x-10 makes computer interfaces, but this is more fun. :-)

I found out about the existence of this beautiful model on reddit.

Here is the model:

The guys entering the contest are out of my league. However, I'm pleased with my quick vase mode print. Yes, I know, I forgot to tell Slic3r to put a bottom on the vase. ;-)
