If you throw up the code once you get it working, I can get the components and put them together myself. I'm about to embark on an ice box humidor project and this could be very nice.

Can it send to an email addrees and not to twitter? Can you hard wire to a plug in the wall style reciptical? Is there a way to add a lcd readout? Can you add a switch to bump up or down the curent humidity reading to match that of a unit already in the walk-in humi? Is adding temp readout a problem?

How many Island Churchills do you want for the above unit? ;o)

Yes (mine will send to both Twitter and an email), yes wall socket is fine, yes you can add LCD readout, yes you can have the arduino control an active humidifier, it already has temp and humidity readouts.

What's an Island Churchill?

Made major progress tonight. Got the new wifi access point up and running and the arduino talking over the network. It's not quite tweeting yet, but we're close.

I'm not 100% sure what he means but some really good cigars can come from islands in the Caribbean area...think about it...

Made a major break through tonight. The little guy is now playing nice with Twitter and publishing the temp and humidity! Check out the feed: http://twitter.com/MyHumidor.

Code still needs polishing regarding the timing of Tweets. I stuffed it in my humidor (don't worry folks, it's under construction and empty right now) on a 9v and will leave it running over night. Hopefully in the AM there will be a bunch of Tweets. Yay!

I thought I was pretty decent with wiring and stuff, but goddamn you're doing some crazy wiring and programming a microcontroller. I only dealt with SCRs and other small components for work related "issues". I wonder what one could do with a microcontroller in my past line of work...hmmmm...

Hmm, it seems like someone could use this to build an active humidifier and save a ton of money...

I really need to learn how to program... maybe this is the project that will make me do that, haha

Currently checking the accuracy of the SHT15 sensor with the 75.5% boveda calibration kit and I like what I see:

She's all done. I was having problems getting the arduino to stay connected to my network. I changed my security settings on the router from WPA2 to WPA and now it works perfectly! I'm so happy it was such a simple fix.

I've now go the little guy in my humidor (which I just started seasoning with 4 84% humidy paks) running on a 9v battery. It's set to Tweet every 1.5 hours. We'll see how long the battery lasts :)

The code I used has been added to the first post.

The 9v didn't last long at all so I'm going with the wired rout:

A little teaser of a Cigar Oasis XL that's been operated on and the daisy chained power cord.


Final updates to come tomorrow.

Very cool Jacob!

Out of curiosity... with the hardware and bits and pieces you used, would it be possible to add on a small monitor or readout screen which would show sort of a stock ticker on the outside of a cabinet or vino? I am picturing those case monitors that you see on high end PCs... this way you'd have the twitter feed for tracking and research, which is totally boss... but you would also have something local to the humidor when you just want to check on it.

This sort of concept:

This is all a bit beyond my level of geekdom... what are your thoughts?

The little guy was running too hot and skewing the temp and humidity readings (don't worry for those of you following Twitter, the humidor isn't 80* F), so I stepped the power supply down from 12v to 9v and moved the sensor further away from the board. This seems to have solved the problem.

Major progress tonight!

The hygrometer in the cigar oasis sucked so I cut it open and replaced its micro controller with a simple transistor switch circuit:



I then added a few lines of code to my wihygro and vuala, the wihygro turns on the cigar oasis when humidity drops below 65%. I've also added a larger secondary fan to help circulate the air up when the cigar oasis is on.

This week I will be doing some final installation cleanup and will post photos of the finished superidor including the wihygro.
