After a tremendously long build spanning almost a year, the Superidor is now finished!

Build thread for the wifi enabled, tweeting hygrometer which I call the wihygro is here: [ame="http://www.botl.org/community/forums/showthread.php?t=38603"]Wifi hygrometer build - BOTL Cigar Forums - Brothers of the Leaf[/ame]. My final code is at the bottom of this post.
Temp and humidity readings are published on Twitter here, www.twitter.com/myhumidor every 90 minutes. Eventually I'll add a warning email function to message when the humidity drops below a predetermined point.
A huge thanks to Mike for the absolutely stunning drawers and GregEigsti at the Aynclabs.com forums for helping me with the wihygro code. Without both of these gents this project wouldn't have been possible.
And now, the finished photos.
In the top right above the shelf is the temp and humidity sensor, just below that is the micro-controller (http://www.sparkfun.com/commerce/product_info.php?products_id=666), on the bottom is Cigar Oasis XL Plus which I've modified and gutted to be controlled by the much more accurate wihygro. Also controlled by the wihygro is a fan in the upper left to circulate air up. Both the external fan and Cigar Oasis switch on when humidity drops below 65%. Temp and humidity are checked ever 30 seconds. In conjunction with the Cigar Oasis I'm using 1lbs of 65% Heartfelt beads.
A potent little 12v fan
I opted to have the wihygro control the humidifier because I found the hygrometer built into the Cigar Oasis to be terribly inaccurate at about +10%. The twisted pair goes to the fan and the barrel jack and black signal wire go to the wihygro.
I replaced the Cigar Oasis controller with a very simple transistor switch circuit.
Here's the wihygro which comprises of an arduino and a wifi shield featuring an external antenna (http://asynclabs.com/store?page=shop.product_details&flypage=flypage.tpl&product_id=29&category_id=6)
I located the temp and humidity sensor (http://www.sparkfun.com/commerce/product_info.php?products_id=8257) a bit removed from the arduino because I found the unit got a bit warm regulating my unregulated 9v power supply down to 5v.
Now I need some more cigars to fill her up...
For anyone interested in building their own wihygro, here is the code I used:
Thanks for looking.
