    I made this, but the drink kept flowing after releasing the button. Presume because there was no air getting back into the bottle? It stopped when opening bottle or pulling tube off the motor. Would using wider tubing for 'exit' pipe help? Recommended diameter?? Thanks.

    why i use 12v motor, but it cannot work

    Neat idea!

    But I have one concern... Since the bottle is open to the atmosphere (dispense tube) the soda will go flat won't it?

    To take care of that problem you would have to have two solenoid valves for each bottle - one in the air line and the other in the dispense tube. Unfortunately I think that over complicates things.

    Could also add a small check valve to each of the dispensing tubes

    How does a check valve solve the problem? CO2 escapes the bottle via the same path as dispensing soda does. And CO2 build up in a normal soda bottle produces a fair amount of pressure.

    This project is for FUN, I know, so its not a big deal, but it just really can't be considered for a 'permanent' installation.

    Nice, even better if you modify the fridge and have the control panel and dispenser on the outside of the fridge. Holes drilled through the door to the bottles on the inside.

    I realize that soda can freeze; however, if you had a side-by-side refrigerator with the water/ice dispenser; you may be able to rig something up. You will definitely need to watch the temperature of the freezer for this...not to mention explaining to your loved ones why they need to retrieve ice cubes out of ice trays, lol.

    Another possible idea may be to use this project on a cooler. Although the ice will melt over time, it would be a neat way to control accidental spills at picnics and family gatherings.

    And also forgot to include the iron welder on the list, my friend.

    What are the sizes of the plastic tubes? Thanks

    This is an awesome idea, definitely save the chance of spillage and they're able to be kept cold.

    this is awesome!

    Looks more like a Pepsi Cola machine to me ;-)
