Finishing Touches

I believe that I've about wrapped up the iOS programming side of things for what I'm going to use on the initial install. Still have a few minor things to get put into the code like the segment selector to output data along with the volume, temp, and fan speed. Those should come along pretty easily. Have the switches tied in though and thought I'd put up a short video showing the output on some LED's.  Also, got the music part of the app updated to allow for seeking through tracks with a slider... will update this for smoother time seeking is a bit jumpy.

Hope you all enjoy!

    Hi Josh,

    I wanted to reach out to you because I have been looking into this exact thing! I want to put an iPad Mini in my dash and have it control my climate control and be my radio. I think that it would be really awesome to do this. I just wanted to see how it is going for you now? And also maybe get some advice on how to go about this.

    I am a developer for iOS already so the programming won't be a problem for me. My concern is how hard and technical it is to get the communications working between your iPad and car. If you wouldn't mind I would really like to chat with you about some of the things you did!

    Thanks,
    Ryan

    Ryan,

    I haven't worked on the project much lately as you have probably guessed. To answer your question in my car the controls are pretty straight forward. Fan control is basically a 4 way switch which my plan is to drive the fan motor from the pic with a pwm signal through a bjt or mosfet for a wider range of speeds. The temperature knob and the air position knob are both like a rotary switch and connects different wires together depending on what they are set to... plan there is trace it out and build a driver board that will use either bjts or relays to make the connections in place of the actual switches. However, as of lately I have been trying to decide if I should build the climate controls as a stand alone digital system that will take commands from the ipad when its connected. That way its still usable w/o the ipad. What year, make and model are you planning to do this with?
