is one Smokin' Farker
try the xBee line of adapters, I think a completed one is $25 at Makershed.com, the unassembled kit is 10 or 15 bucks
This actually crossed my mind the other day on the way home from work. But i wanted to use a Raspberry Pi, Two temps, (one monitors meat temp, one monitors grill temp) and the one that controls the power for the fan.
I didnt see any reason it wouldnt be feasible, may take some doing and may have to write some software for it. but keep us posted, i may get mine underway in the winter when i actually have time to do it
My only problem, is, right now, that the fan draws 12 V/0.07 A, (I swear it was advertised as 5 V but whatever), and the Arduino power pins only supply 5 V, which really doesn't move the fan too well.
Can any electricians help me out here? Will the fan not work or do I need to introduce external power from somewhere?
Thanks
I did but it resides in my brewing system
Well mines done, just tweaking the Software.
I used Maverick ET732 probes with a 22k resistor.
Were you able to use the Arduino shield for wifi? I read some time ago on the tvwb thread that it no longer worked for this application since a different version is being made and sold now.
twinsfan: keep us posted!
Different view
The green PCB is the back of the LCD display. I originally had made it to control my two WSMs. That's why there's a 1/2 switch and the display has info for two cookers.
Eventually I want to lay out a real PC board instead of the hand wired board. I also want to lay out a nice aluminum front panel that looks way more professional than my hacked up plastic box.

I am currently in the process of building a controller using an Arduino. I wanted to take range out of the equation so rather than use something like ZigBee or Bluetooth I opted for a USB host shield. I had an old Android phone laying around which requests voltage reading from the Arduino and then it acts as a server that is connected wirelessly to my network. I have an Android Server app which I've written and an Android Client app which can connect to the server. You can set alarms and graph the temperatures. I can go out on a date with my wife and still check my temperatures even though I might be 30 minutes away. My eventual plan is to use a different micro controller with slightly more processing power and a wifi shield so that I can remove the need for an old android phone. The server software will run on the micro controller and the same Android client app which I've written will connect to and communicate with the device over the internet/intranet depending on how it is setup. I'm still in the early stages, but as I get farther along with it I will post more information here.
I'm not going to pretend to understand everything you said, but finally... someone is messing with an Android temp controller!!
Are you building a temp monitor or a PID type controller? Great job so far!
Hey, Bryan welcome too the Brethrens. Its about time you posted over here. :thumb:
Im also building a Rasberry Pi BBQ controller, I should have it finished next week while i take a week off from work.
