I have the guru wifi and have it integrated with an android app I built. Works perfect but I'd love to build my own controller though so will be watching closely. Might be cool to do some comparisons with the guru when all said and done. Theirs actually adjusts their fan speed algorithm based on the smokers efficiency. Might be a useful feature to consider as I'm sure it takes a more aggressive setting to keep an offset going than a ceramic. |

I have built a Raspberry Pi controller for my UDS following Bryan Mayland's Step by Step.
The Raspberry Pi is a credit-card sized computer- a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 Megabytes of RAM The complete project is actually very easy, the soldering is the hardest part. The cost is about 110 dollars for everything A case is still in the works but the design is being 3d printed and the files will be available to order if they fit correctly. The complete Pi-Hetermeter. You can see a spot on the board for a wireless receiver(below the "NO" on the display), when used you can add wireless probes This pic shows the Hetermeter(top) and the Raspberry PI(bottom) More info http://tvwbb.com/forumdisplay.php?85...BBQ-Controller Raspberry Pi Heatermeter http://tvwbb.com/showthread.php?3567...yPi-Standalone A list with links to all the needed components https://github.com/CapnBry/HeaterMet...r-4.0-Hardware A Step by Step https://github.com/CapnBry/HeaterMet...r-4.0-Assembly Anybody can build one without experience. The WRT54G/heatermeter was my my first project and I have learned alot doing it myself. Bryan Mayland over at www.tvwbb.com will answer every question and is very helpful. He also continuosly upgrades the software putting in around 30 hours a week on it. Here is a link to my still in use linkmeter and it also has a link to my older thread http://www.bbq-brethren.com/forum/sh...ht=heatermeter

If you have any questions about how my stuff works (in order to keep the size down, I've taken some shortcuts that may make the source more difficult to follow) I'd be happy to share ideas with you. Can't wait to see what you come up with! |

Are there any Android UI developers out there? I could use a hand in making the screens look more professional. I don't have any problem with the logic and algorithm stuff but my UI skills suck.
Update: I'm still waiting for my IOIO to arrive so I'm focusing on the Android programming. I've written some of the UI code and a service to monitor the smoker. I couldn't find a PID algorithm written in Java so I'm converting the one written for the Arduino. I'm getting help from the author but it'll take a few more days. Once I get all the basic screens finished I'll post some screen shots to get some feedback (assuming I can figure out how to get screen shots on Android). The cost so far is $80 (including shipping--thanks Amazon!). I still need to get the probes which I figure will cost $30. Anybody know a cheap source for Maverick probes? The last major item that I haven't bought yet are the parts that will be needed to attach the fan to the smoker; I still have no idea how I'm going to do that. Not including the Android (which is perhaps not fair) the total cost should be $120-$130. |

Hey moontz, thanks for the offer! My current plan is to create all the screens with the required controls, then I can pass that part to you for improvement. You can do as little as just making sure everything lines up or you can go crazy with sliders and icons or whatever else you think improves the interface. Then we can post screen shots here to get some feedback.
Once I get the PID stuff working I'll put the code up on github or SourceForge. Do you have a preference? If you don't care I'm leaning towards SourceForge since that's where most of my projects are. I'm hoping to have it up by the end of this weekend. Edit: Forgot to answer your complexity question. Right now there are 3 screens: 1) Initial screen with multiple settings (i.e. text boxes) and a button to initiate the Android smoker service. 2) Status screen for displaying current temps, fan speed, and input to change thermostat setting. 3) "Settings" screen for shutting down server. In the future it will have other little-used settings like PID values. Some day I'd like to add more functionality like graphing the temperatures, setting alarms, and automatically changing the temperature after a certain time. Or maybe something that turns down the heat after the meat hits a certain temperature. If/when I add wireless functionality there will no doubt be more screens. There's all sorts of crazy things we could add in the future. Last edited by Deeg; 10-10-2012 at 12:12 PM.. Reason: Forgot to answer moontz' question on complexity. |

Update: Still moving forward and working on the PID and the screen communication. Moontz, I should have something by tomorrow night. Do you have have suggestions on what to use to plot graphs on Android? I've been looking at http://androidplot.com and it appears to be simple but maybe you have experience with something else.
CapnBry, how steady have your temperatures been using the HeaterMeter? I'm just curious as to what my ceiling will be. Version 1 of the UDS controller will expect the phone to be tethered to the controller. The IOIO can use a bluetooth dongle for communication so theoretically someone can use an Android phone to connect wirelessly but that will not be my initial focus. Right now the lowest OS version that will be supported is 2.2. I don't see a need for that to change. For version 2 I have an old Motorola Droid that will spend the rest of its life connected to the UDS. At some point the Droid will act as a web server so I can monitor the UDS when I'm away from home (and also taunt my friends with "look what I'm cooking!"). This road map may change on a whim as I get new cool ideas or lose interest. :) |

I applaud you guys for this, time, money and knowledge. It's awesome but it kinda takes something away from what BBQ is in my opinion. After all it is BBQ not BBIQ. Maybe I'm a little jealous which I can admit. I'm an electrician by trade so yes I have put some thought into it. I guess I like the Nostalgia of the lack of technology.
Keep up the good work, can't wait to see you guys get it figured out.

This thread is WAY over my head. I'm able to figure out what you're trying to accomplish, but that's about it. Regardless, seems pretty cool. Good luck!

Watching this one since I have an arduino coming just for this.

Just so you know, I don't plan on using an Arduino. This build is using an Android device and a couple of break-out boards. See CapnBry's excellent HeaterMeter if you want to use Arduino. |
