@Nomad As a general rule Roasting should not exceed 20 min to second crack What you are describing is baking

Looking around a bit on the internet there seem to be some problems with the HC06, and especially from DX. try looking here: http://arduino.cc/forum/index.php?top...c=111080.0 especially the blog link at the bottom. Maybe you can change the firmware and turn it into the HC05. The HC06 is the older version, HC05 is the newer version according to JY-MCU. |

Hmm you're probably right. I should look into these level changers. Actually I have just purchased 4 of the ones in your link :) I also have this Arduino bluetooth shield from DX which I assume must do the level conversion on board. http://dx.com/p/arduino-bluetooth-shi...een-138098 And I have attached my Andriod app and source code. Let me know how it goes. The code is a modified version of the Bluetooth Chat sample file.

I've installed the apk but I can't do anything until my bluetooth arrives (just ordered it). I installed the android SDK a few months ago but haven't tried using it yet, so this will be a good opportunity. You decided not to try plotting the output on the android, or is that too complicated in android? I started to suggest there is unfortunately no version of Processing for Android but I checked and there IS - however it seems the serial library doesn't work for Android, so it looks like its not much use to us for now. Android programming is pretty difficult to get started on! Is your device Android 7, or is that just coming from the Bluetooth Chat example? I was getting compiler compliance errors. |

Eventually I want to include data logging and graphing on the android device. But this is quite possibly too complicated for me. It took a fair bit of head scratching to get the Bluetooth chat example to do what I wanted. This was my first attempt at programming for android. Are you using the Eclipse IDE? There's an option there somewhere to 'Clear lint markers' which seems to help with errors that appear each time I open the project. I can't recall if I set it to Android 7 or if that came from the Bluetooth chat. I don't actually have an android device at the moment! I tested it on my brothers phone but I hope to pick up one of the new 5" phones soon. I'm thinking that the big screens should provide enough space for a graph as well as buttons. |

Bhante I got my level converter modules in the mail today and they work a treat. My 'non working' bluetooth module is now working well. Thanks for the advice! |

I think Brad mentioned a while ago that his server with all his images went down. I am not sure if he is rebuilding/repairing it or not.

Brad, I would be glad to help you edit and restore them. If the file names are the same it should be easy to match them to where they belong.

Sorry I can't find any of the photos of the controller. When I get a chance I'll take some new photos. I did find my wiring diagram showing how everything is connected.

Brad. Thanks for the diagram. The only part that I cannot pictured in my head is how did you connect the bigger display to the LCD adapter and the buttons.. Rgds. |

I have used the LCDapter board which is connects with the 4 wire I2C connection as shown in the diagram. The 4x20 display uses the same pins as a 2x16 display. The LCDapter allows the LCD and buttons to be attached to it. I got mine from Jim here http://www.mlgp-llc.com/arduino/publi...o-pcb.html |

I took a few quick photos of the controller today. The inside is a bit of a wiring mess!
