Lego Liquid Dispenser

Hello,
I was surfing on Youtube looking at some NXT vids and I stumbled upon this NXT liquid dispenser.



Here is a description on how it works:A Lego Mindstorms powered water dispenser. It uses two motors to directly drive he air compressor, and pumps air through the Lego pneumatic rubber tubing into an airtight water container, and water is pushed out from this container through another rubber tubing and exits through a nozzle in the front. The motors are driven whenever the touch sensor is pressed. Features include a push lever, a water container bay, rubber band powered container retainers, a glass pad and more. The NXT run LeJOS and the source code for this program and other programs using different sensors as well as pics can be found here:

And a 2.0 version
This one is a little more simple but it shows a different way of using the NXT motor


Enjoy!
