KegDroid: Combining Arduino, Android, and NFC to Dispense Beer

mikejuk writes, quoting I Programmer: "If you are looking for an exciting hardware project, KegDroid deserves a look. It is a sophisticated system that involves Android, Arduino, NFC, plumbing and — beer. Perhaps the final stroke of genius is to package the whole thing in a Droid body. Some how the little green fella looks at home on the bar. You have heard of desktop and laptop apps now we have bartop apps to add to the list" Details are fuzzy currently, but from all appearances this is a repackaged KegBot in a very fancy shell.

To be fair, all it does is open and close the valve to control whether it should or shouldn't give beer. The guy is doing the rest of the work and it looks like he's never poured a keg before.

• He doesn't use a clean glass. He should first rinse the glass in cold water to clean and cool it.
• He opens the tap just a bit, this guarantees to create a lot of foam. He should open and close it completely and quickly.
• The angle is wrong; he should start at about 45 degrees and then gradually move it towards a vertical position. Holding the glass at a too small angle like he does will generate too much foam.
