This instructable is finally complete with the now missing steps.  The Dome and torso section coverage were a little sketchy the first time around as one of my SD cards went missing.  It was since found when tearing out some floor molding in the kitchen.  Geez, why do I never look in the obvious places... I added about 25 more photos, commentary and an additional step to round out the build, so now their is no excuse to build one of these. . .

Note: was given the option to enter this in some of the new contests, that would be cool if i won and all, but its more there for show and tell purposes.  If someone votes it in though, who am I to argue, just sayin'.... love to win a Wookie Bag!

While your at it, load up on some Star Wars Vader's Dark Side Roast Coffee from ThinkGeek and this project will be complete

Star Wars, Love it or hate it.   One thing you can’t deny is the universal love and identification of one of its side characters R2D2, the little astromech droid who could.   Only now, he even better… cause he makes me coffee.  Of course anyone who makes me coffee goes up a few notches, so why not have a world renowned icon make it for you.  And for the tea drinkers, well… I guess you could use it to brew tea, if you like that sort of thing, probably while you watch Star Trek Deep Space Nine… 
In my world, Darth Vader doesn’t go all soft in the end.  Instead of taking off Luke Skywalkers hand he takes off his head, the rebel alliance is quashed, ewoks are served up crispy fried on a stick and Darth takes R2D2 as his trophy trinket, turning him into his morning caffeine delivery device.  AKA R2D2 Dark Roast Edition.
Betcha Yoda didn’t see that coming, huh George Lucas

Thank you all who have posted all the great comments!  It was a great build!



WARNING – UBER LOOSEY GOOSEY SCIENCE PART
So the whole concept behind this was to have a coffee maker that could be used to brew coffee quickly for larger dinner parties that we have from time to time.  A regular coffee pot is just too slow to brew pot after pot as its being emptied so quickly by caffeine crazed guests.  Enter the industrial BUNN type coffee maker.  It uses a tank of water that holds two coffee pots worth.  First you pour in two coffee pots worth of water and turn the unit on.  It takes about 5 minutes to get the water hot the first time around, then it waits for you to add one more pot of cold water, this is when the magic begins.  As you pour cold water into the hopper tank, it descends a down a tube to the bottom of the heated tank.  Now this tank all ready has water in it that is nice and hot.  The cold water which naturally wants to stay on the bottom anyway pushes the heated water up and out an overflow at the top of the tank.  This overflow is connected to a tube which has its end set just below the level at which the hot and cold water find a balance.  As water flows out the tube it creates a siphon effect draining out the hot water from the reserve tank and allowing space for the cold water in the hopper to fill up.  Now the hot water has to go somewhere, so why not channel it into a coffee ground hopper where it brews up a tasty and oh-so quick pot of coffee.  The BUNN coffee units spout is kinda like one of those rain shower heads, where it sprinkles down hot water over all the coffee ground area at once.  This wets out the grinds quickly allowing for a quick brew.  Regular home units trickle it out at insanely slow speeds often inducing madness in morning commuters and small dogs alike.  Finally the large heater element takes very little time to heat up the now cold water in the tank and by the time you have drained the first pot of coffee, and gotten new coffee grinds ready the cycle is ready to start anew, remembering the tank holds two pots worth of hot water so is all ready ahead by one pot.
