    Hey everyone,

    Well this has been a project that's been on and off my drawing board & work bench for a little over 5 years now but never quite reached a complete state.

    tripping over it last week I said to myself i really should finish it off.

    So basically its a drink dispensor in a PC case.
    I'm not going all out with Arduino or Raspberry automation and after taking a look into the difficulties of dispensing carbonated drinks I've decided to keep it very simple.

    It all started with an abundance of spare water cooling gear.

    RUM PC MK1

    I started off with a spare thermaltake case and a few bits and pieces.

    [​IMG]

    had a custom twin chamber perspex res that would act as the window on the side panel

    [​IMG]

    [​IMG]

    using some solenoids I had visioned the liquid constantly circulating and with the flick of a switch it would redirect out and into your chalice.

    mounted it all up and even put some LED's and a motherboard behind the rez to complete the look.

    [​IMG]

    [​IMG]

    however I soon lost motivation and never got round to actually connecting up the solenoids and switches.

    RUM PC MAC MK2

    after getting hold of some old Mac Pro G5 Cases my motivation was renewed.
    so i stripped one of the cases and made a start on the RUM MAC.
    The case will be finished off in a Gloss Black powder coat with the Bundaberg Rum logo one one panel and the Apple logo on the other.

    I made a false floor that i could mount to and run cables behind

    [​IMG]


    Originally I had planned to reuse the 2 chamber rez but after a test mounting I found it would be to hard to fill as well as trying to drain and keep clean between use.

    so instead I will simply use the 1125ml bottles rum bottles themselves (one dark rum the other white rum)
    After finding the solenoid solution to be over complicated I have also decided to ditch the "Loop" scenario and go with a simple pressure pumps instead

    I made a blank plate for the rear to cover the holes left from the back plate
    cut out the section for the side cover latch.

    Just awaiting delivery on these taps

    that will mount in the reinforced plate at the top where previously there had been the slot for a ROM drive

    Pumps and Pressure Switches

    so after a few hours of researching I have found that for my price range there isn't anything out there in the exact pump i'm looking for.

    so instead I'm going to use the below pump
    12v 3Lpm 70 PSI Diaphragm pump
    1.5m of Vertical Suction, run dry and self priming.
    [​IMG]
    http://www.ebay.com.au/itm/311702497396?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT

    and i run a seperate pressure switch and 12v relay to get a usable pressure cut off.

    I spoke with the vendor and these will fit the job.
    Normally Closed and once it hits ~3psi Opens the circuit (Switches off the pump relay)

    got another hour or 2 work done on it over the weekend.

    Drilled the holes to mount the taps.
    [​IMG]

    drilled out the hole for the power cord.
    lightly sanded rough spots on case
    test fitted the taps.

    Very nice! I was wondering how the gold and black would look on the Aluminium of the G5. It seems to contrast well and not get lost in the G5's bulk, looks very classy.
    I'll be keeping an eye on this one, keep up the good work.

    Hey Cannula

    The plan is to have the G5 case powder-coated inside and out in a gloss black.
    should make those gold taps really stand out.

    Almost forgot.

    i did the re-wiring of the PSU.
    this G5 PSU ran metal power rails instead of traditional cords I decided to gut it and replace it with the insides of a cheap 450w PSU.

    Wired in the fans to 5v (dont want them running full speed)
    and connected the green wire to earth (so the psu auto powers on when a cord is connected)

    [​IMG]

    the mounting holes from the G5 let me mount 2 of the PCB corners, I used standoffs for the other 2.

    I cut off all the standard wiring plugs and wired a few of the 12v's into a terminal block for the Pumps and Relays
    setup another terminal block for the LED's.

    everything that i didnt need (rest of the 5v, 3v and spare ground wires. I just cut short, insulated and tucked away.

    [​IMG]


    just need to make a plate for the Plug to fit into the hole at the rear of the G5 PSU

    just a small update

    got the base plate done
    NOTE: I have replaced the bolts with counter sunk ones.

    I have a couple ideas for the inside panels. so i'm after some input or other suggestions
    1. Vinyl wrap or hydro dip a PCB design onto it.
    2. Powder Coated Black to match rest of cast
    3. Powder Coated White to have it stand out inside case.

    NOTE: white LED's will be used to illuminate the bottles

    What about a real motherboard in there sans gpu hsf, etc?
    What sort of bottles are being used? Off the shelf rum bottles or do you brew your own and use something else?
    If they are off the shelf, maybe the logo? eg Bundy rum = white bear on black background. Too tacky?

    Hey /invariance\

    thanks for the ideas.

    yes i'll be using off the shelf bottles.

    one tap will be a 1125 bottle of normal Bundy UP Dark Rum
    the otherside will change from time to time, might be a Bundy 5 white rum, or a special release bottle or select vat.

    so its important that the mounting for the bottles can fit most glass bottles.


    As for a bundy logo i was going to do one on the outside of the case. then on the other side do an Apple Logo. or maybe i could do a bundy bear logo on both sides but done in the shape of the "Apple" logo.

    unfortunately by the time pumps relay's and the bottles are mounted i don't think i'm going to have room for a mobo and extras.

    Moved into the Worklog Forum - Woo Hoo

    I should take this moment to mention and thank the sponsors of this build.

    1. My Wife :D
    - For letting me spend the money and invest the time
    2. My Kidneys
    - Its a love hate relationship. I do love a drink and I'm sure they hate me for it. :lol:

    I got a little bit more work over the weekend

    [​IMG]

    pumps arrived, happy with their size, they are a little on the noisy side but as its just dispensing 30ml or so at a time they are not on for long periods.

    [​IMG]

    I have a nutsert tool from working on my 4x4 and camp trailer so i thought id put it to some use in creating mounts for the pump.
    works just like a pop rivit, but instead of the centre section of the rivet its threaded.

    [​IMG]


    one down, few more to go.......oh and I put a nutsert in :D

    the nutserts let me get the pumps in and out without having to remove the base plate (vs if i had of used nuts and bolts)

    Update!!!

    Update!!!

    well the update is there is no update.
    I'm waiting on a friend of mine to complete the T pieces that will house the pressure switch.

    25mm Solid Ally Round bar is being used.

    a 3/8th Hole is drilled straight through on the lathe, then tapped with a tapered thread to fit standard copper hose barbs

    In the side a M10x1mm hole is drilled and tapped to house the pressure switch.
