    i could do that as well but no need, the board I posted above is a mega328p on board with a usb port for firmware uploads, you can program it using the arduino interface once the bootloader has been loaded. I can add a header for more I/O pins as well, the one output pin that is there now is powered by a tip122, its pulled high and triggered low in the mcu so you can hook it to the negative of a relay coil that drives something like the afterrun pump. there is a header on the bottom for the temp probe you are using, and a port to attach the canbus shield that can pull all the engine data you need. I priced out the pcb at osh park and it would be $60 for a run of 3 pcb's.
    Never argue with an idiot, they'll bring you down to their level and beat you with experience.

    I dunno how this will dictate what Rob wants to do. Rob? I am just shadowing him and typing commands into [a pretty shitty] IDE.

    Is that the same chip on the nano? If so, shouldnt really matter, just change some pins before compiling?
    What he is doing sounds pretty sweet. If the 2 are somewhat compatible, options are always good.
    There are only 2 things needed to make an Audi work properly - Duct tape and WD40. If it moves and it shouldn't - Duct tape. If it doesn’t move and it should - WD40.

    same chip as the uno, but still easy to swap pins.

    Rob, we should be fine to spearhead our way with what we have planned. I am writing the code modular enough that the physical architecture doesnt really matter. anyone would be able to change the code with relative ease to meet their needs.

    I have a mosfet, 5 fans, and some nano's en route. I ponied up the extra cash for the US located ones, that way I don't have to be at the mercy of some customs agent on a friday evening.

    also on of the benefits of the arduino ide is just changing the target board and swap a few pins in the code and it will port right over to another board.

    That is a great point actually.

    Just curios, with this new board you’ll be using the uno as a board in the IDE?

    Give me a day or two and I'll build the bootloader and set up the hardware files for arduino ide, then you just choose the board from the drop down, it will have it's own custom name.

    Are there advantages to making the board from scratch, as opposed to making a board that a nano plugged into?
    There are only 2 things needed to make an Audi work properly - Duct tape and WD40. If it moves and it shouldn't - Duct tape. If it doesn’t move and it should - WD40.

    Space, custom, and exactly everything you need. Less wiring too it’ll look super clean. We can also send a fritzing file in for manufacturing or with eagle cad. I am lazy though, the nano will be fine :D

    Custom and exactly what we need shouldnt be affected.
    Space maybe a little bit, but it would be losing a chip, and only gaining a set of headers to plug the nano into. And the nano of course

    If we were producing a commercial product it would be a no brainer. But I’m ok with the spaghetti mess.

    For sure.
    Seems to me that the further projects like this get from "off the shelf", the shorter the life they have.
    Sounds like it will have excellent compatibility though so can do it however we like.

    Got a chance to frankenstein something up and see how the mosfet would do running a fan.
    Ambient was 26C, it leveled off at 28.6C after running for ~60sec.
    I would have thought it would have made more heat, but only +3C is way better than I expected.
    Will have to see how it does when we start switching it on and off to control fan speed.

    There are only 2 things needed to make an Audi work properly - Duct tape and WD40. If it moves and it shouldn't - Duct tape. If it doesn’t move and it should - WD40.

    Quicky update on this.

    This is just an example and basic layout. (much of it is just stuff to mimic what is in the car for testing)



    Switches left to right
    1- Basically the alternator. (how the oem fcm knows if the engine is running or not)
    2- Aft run switch
    3- Manual override switch. (turn the fans on manually if needed)
    4- AC on switch. (how the oem fcm knows if the ac is on or not)

    Lights from left to right (these just represent fans, aft run pump, etc)
    1- Front fan
    2- Rear fan
    3- EFK
    4- Aft run pump
    5- Low switch emulator sig. (tells the oem fcu the low switch is tripped)
    6- High switch emulator sig. (tells the oem fcm the high switch is tripped)

    The thing with "TMP" on it is a temp sensor so we can move the temp around and see wtf happens.

    The power supply is car voltage.

    The oscope is to see wtf is going on.

    We are using a nano, but the uno does pretty much the same thing here.

    This is engine running, and the temp just above the efk on temp.
    The efk is lit, and running a low duty cycle.




    This is with the temp a bit higher, efk lit, and running a higher duty cycle.

    This is engine running, and temp above the low temp switch setting.
    Efk is running 100% duty cycle
    The front and rear fans are running 1/2 speed (50% duty cycle)
    The low switch emulator is lit, and would be triggering the oem fcu low speed if you were only using this to run the efk.

    Engine off, aft run switch tripped.
    Front fan running 50% duty cycle
    Aft run pump on.

    Will run until aft run switch turns off, or the set max time.

    Engine on, override switch on.

    Efk, front, and rear fans running 100% duty cycle.
    High switch emulator on, and telling the oem fcm it wants high if you are using it.

    Being that I’m close to Rob, I can be a test car for this. All expenses paid of course.

    But, but, no fancy lights and switches and shit on that one

    The thing we are working on would be fully configurable fan controller replacement if wanted.
    Or just a configurable efk controller that also allows you to configure the switch points of the oem fcm, and some other stuff.
