University of Washington EE478 2009: Automatic Wireless Drink Mixer
Automatic Wireless Drink Mixer Designed and Implemented by: Robby Connor Richard Evan Cross Zach Rasmor Automatic drink mixer features: -Remote touch screen allowing users to pick from preset drinks or customize their own. Touch screen donated by 4DSystems (www.4dsystems.com.au) -Remote interface sends drink selection via wireless to the main controller (Microchip PIC32). -Local LCD touch screen allowing users to scroll through preset drink options and select a drink. -Infrared cup sensor that detects if a cup is in the fixture. Liquid will only dispense if a cup is present. -RFID sensor that detects if an RFID cup is in the fixture. If so, it remembers the last drink that the cup ordered. If it sees the cup again, the local LCD will jump to the last drink selected. -Drink valves are turned by servo motors -Windows GUI that allows the user to change the available liquids and add new preset drinks (not shown)

- when using wireless cameras if you disconnect the main camera will that kill the feed to the others?
Cool! I guess the proportions wont be the same if one item is about to run out, since the pressure. Some liquid flow-ometer would be more precis. Really cool though!
I see what you are saying and got the point. Good job.
Oh, and –
C – If a cup isn’t present, the order should complete without user interaction once a cup is placed underneath, unless the order is cancelled.
.
Also I’m wondering if a PIC32 is even needed for the dispenser system, sure a powerful chip is needed to drive that touch screen display, but the dispenser back end seems nothing more than a ‘valve’ timing system which also needs to store the liquid proportions.
I’m guessing a PIC16F877A wud b ok. I’m happy to be corrected though! ;-)
Awesome! great work guys.
I’m loving the quantity customisation feature, future improvements could be added –
A – You can scale the overall timing system for all four servos and make a larger drink of the same proportions. In fact a fifth slider on the customisation screen for customising this would be great.
B – A voice feedback system for user friendliness- “Choose your drink.”, “Place cup under the dispenser”, and “Your drink is ready”. etc. Loud so you can hear it in a bar scenario.
way awesome…is pic easiest to get started with or do you pefer avr/arm?
Awesome Job Guys! A very cool final project.
I see an IDE cable!
I want one!!!
pity, that’s only water. lol
there is everything for iphone now-a-day. i’m very sure its not going to be left out.
That’s cool and all, but you should have written an Iphone app for the drink mixer interface!
jk, good job guys!
