Linux-Based Bar-Monkey 551

An anonymous reader writes "The Bar-Monkey is a bar built around a 486 running linux that can dispense an 8 ounce mixed drink in under 10 seconds. It uses a Matrix Orbital Serial LCD panel with a keypad built into the bar surface for user input. Three Harvey Mudd College students built the bar in their spare time last semester. The bar holds 16 ingredients with which it can currently mix 188 drinks stored in its drink database. Total project cost: $235."

      Bahaha that was a great scene.

      For those of you who missed the reference, it's from the highly underrated Fifth Element. This guy is pouring out his heart to a bartender, and asks if he knows what he means.

      Camera angle cuts over and the bartender's a robot. It shakes it's head no and askes "You want some more?", which is funny since that's pretty much the reaction I've gotten from human bartenders the two or three times I've gone to drown serious sorrows.

      Windows would incorporate Drinking Rights Management to ensure kiddies are only served root beer.

      Before each drink request, imbibers of legal age must slide their driver's license through a slot for verification, along with the card of a preauthorized designated driver (even for home use). Remember to make each successive drink request with the same glass you used for your first request, or nefarious activity will be suspected and the tap will shut down, forcing you to call Microsoft for a reactivation code.
      • Oh, and add to this that the drink master remembers your drinking habits including what drink, how many, what time of day, and what day of the week. As such, if the drink master feels you are overdrinking it will send your address to counselors and doctors who will then contact you by unsolicited mail. The drink master will also make your drinking habits available to your employer for a price.

      Why not have this baby track it's users by sex and approximate weight?

      Since the user would get all their drinks from the machine, it could generate a report on what a user's BAC is likely to be (x number of drinks over y amount of time, adjusted to body weight). It could flash this info the the user everytime they buy a drink, so they know if they're going to be over the legal limit for driving or if they're getting close to dangerous levels. Hell, the barmonkey could even cut people off.

    The Bar Monkey
    Designed and Implemented by Steven Avery, Dustin Cooper, and Brad Greer
    of Harvey Mudd College

    The Bar Monkey, simply put, is a vending machine that serves mixed drinks. It houses 16 reservoirs which currently contain the following ingredients:

    * Vodka
    * Rum
    * Tequila
    * Whiskey
    * Gin
    * Amaretto
    * Triple Sec
    * Kahlua (or coffee liqueur)
    * Midori (or melon liqueur)
    * Orange Juice
    * Pineapple Juice
    * Cranberry Juice
    * Sour Mix
    * Cola*
    * Tonic*
    * Grenadine*

    *Ingredients currently under consideration for replacement

    Using these 16 ingredients, a total of 188 different drinks can be made, with the included ability to add ounce increments of each ingredient to customize (or create) a drink. The drink database is easy to update and nearly infinitely expandable.

    Customers sign up for a user account, for which they are assigned a unique, 5-digit, hexadecimal PIN. The account is debit-based, with each drink charging the customer at cost for the drink they are purchasing, automatically deducting from their account balance.

    All told, the project took about 3 months and $235 to complete. It is worth mentioning, however, that the LCD (the most expensive single component) was donated (approx. value: $100+), and various other components were otherwise acquired for free. The Bar Monkey was graciously funded by West Dorm HMC, even though we were overbudget by $85. Continual maintenance and occasional improvements are still always a concern.
    Some Pictures:

    Beta Testing
    Here's the cabinet when it was just a few shelves holding empty 2-liter bottles. One pump is hooked up to the computer for the purpose of taking time-constant data.

    Soldering I
    Having collected the time-constant data, Steve and Brad dutifully solder half-inch jumpers to each of the 4 leads on each of the 16 relays. Neither of us knows, to this day, why we did this outside.

    Soldering II
    Closeup of the meticulous but tedious jumper-soldering process.

    Bartop Under Construction
    The unfinished bartop, with various tools, containers, and other helpful things strewn across it in the midst of hard work.

    The Monkey's Central Nervous System
    The finished relay board, connected to the computer via parallel ports. The computer is running the Bar Monkey program, which displays the drink code prompt on the LCD.

    LCD and Keypad Closeup
    The above-mentioned drink prompt, but closer.

    Behind the Scenes of the Relay Board
    It looks really nice and neat on top, but the relay board was quite possibly the most difficult part of the entire project. What you see here are 16 relays, 16 diodes, 16 resistors, 16 transistors, and approximately 70 small segments of wire (not counting the 64 jumpers).

    Inside the Finished Product I (shown above)
    Pretty self-explanatory. The pumps and their respective reservoirs in place, the computer and relay board safely tucked on a shelf, the LCD behind a half-inch of acrylic, and all the tubes pulled through the PVC dispenser neck.

    Inside the Finished Product II
    Same as above, but from a different angle.

    Electronics Closeup
    The LCD, with extension cable to the keypad and serial cable to the computer, is at the top right. The bottom of the computer is unimpressive, though dominant in the frame, and the relay board is seen off to the side.

    Outside the Finished Product
    Here we see the Bar Monkey as customers see it, complete with Dustin's excellent stencil design and the nozzle, which is removable for cleaning.

    The Finished Bartop
    The top of the Bar Monkey, covered in rugged black plastic with a viewing window for the LCD.
    Finished LCD and Keypad Closeup
    It still looks pretty much the way it did when it was unfinished, only now it isn't just laying on the floor.

    Drink Confirmation
    The true beginning of the customer's experience with the Bar Monkey.

    Technical Specs:

    * Runs a program written in C by Dustin Cooper, in Linux.
    * Bartop is approximately four feet above the ground.
    * Holds approximately 1.75 liters of each ingredient.
    * Uses 16 windshield washer pumps run by a 12V adaptor. Pumps are connected in parallel and run sequentially by the program.
    * Dispenses an 8 oz. mixed drink in less than 10 seconds.
    * Currently has 30 registered user accounts, with expected rapid growth as people cease being broke.

    My biggest beef with the interface is you have to enter a numeric code to pick a drink thus requiring some chart of all 188 drinks. Once you've partaken of the Monkey a few times, are you really going to be manage it? A-ha! The interface is intentially difficult to act as a throttle on consumption. Once you're sufficiently drunk, you can't manage to order another.

    For v.2 I'd use a bigger LCD and display actual drink names, possibly grouped hierarchically by type or primary ingredient. Drink numbers would remain to act as a shortcut for patrons who remember the number of a drink they order often. A touch screen would kick ass but I think they're less robust and more expensive.

    Since each patron has an account, I'd give it a "The Usual" button which could be set for each patron. Instead of a PIN, I'd also consider a card swipe. They're students so they could use their student ID as the card.

      Yeah, peri pumps are great. We have hundreds of impeller pumps to recirculate ink on our presses, and the are always dying, going off balance, or developing other problems. Plus, they have to be meticulously cleaned with every ink color change. We're moving to peri pumps exclusively in the next few months...just rinse out or throw away the tube, snap in, and go.
    • When I was in college, a friend related a story from when he was in high school. He thoroughly cleaned out his windshield washer system (pump, reservoir, tubing, etc) and ran the tubing to a nozzle under the dash. He then filled the reservoir with alcohol , and was able to make his own mixed drinks while road-tripping. He even hooked up a reversible pump so if he ever got pulled over, he could just suck the drink back into the reservoir!

      (yeah I know, DISGUSTING. and STUPID too!! but he was in high school, so he was young & stupid by definition :) )

      Anyway, his "system" worked great until one day when his dad used the car & the windshield was dirty.......
    • Yeah I think those would be great. Unfortunately the ones you were pointing to were specialised and very expensive. I think a good alternative would be to go to your local model shop and buy a fuel pump. These are used for getting the fuel into model planes etc. These are almost always peristaltic pumps. You can either get a ready motorised one or get a manual one and hook up a stepper motor to it for precision.

      As long as they've never been used to pump fuel they should be fine, plus as they are designed to pump fuels the alchohol should not make it perish or degrade.
    • actually the solution is to use solenoid valves and CO2.

      if you would simply buy a few old pepsi or coke premix containers that are stainless steel and simply use older but still purchaseable at low cost soda fountian parts you can have each of the canisters hold each ingredient in a fridge. pressurize each canister as they are supposed to be via CO2 and use stainless solenoid valves. you wont get super accurate dispensing unless you do aholding bottle... open valve 1 fill 1 ounce length of line, close valve one open valve 2 to dispense while valve 3 opens to purge the line to actually do the dispensing.

      I'd just go with a simple timer and open the valve for a certian time constant.. if someone accidnetly get's a stronger drink... whooptie doo.

      I discovered adding a soda bar to by basement is dirt cheap if you go for the older technology.. I purchased the premix-canisters from ebay for $5.00 each and simply use food grade tubing and CO2 is the absolute cheapest gas on the planet.

      PROBLEM... Orange juice is horribly acidic and will attack anything... including stainless steel. get low acid juice or remove that ingredient from your selection.

    • There's a good story about the windshield washer pumps that I haven't seem anybody tell yet. Before I tell it, though, I need to say a few quick things. The first is that I've spent a fair amount of time with Harvey Mudd students recently, and they tend to be seriously gifted individuals. I've also spent time with M.I.T., CalTech, and Rose Hulman students (to name a few), and I have to say that the Mudders are seriously underrated on the global undergraduate stage. These folks are personable, inquisitive, dedicated, and enormously talented. And funny. Really funny.

      Forgive me if I'm telling it wrong, this is second- and third-hand information.

      Not long after the bar monkey became operational, it was being used over the course of an evening to serve cocktails in the lounge. When the students retired for the evening, they deactivated the monkey and left to finish their 'stems homework and whatnot. Later that night, there was a localized power disruption, though I don't know its duration. What I do know is that the monkey wasn't on a UPS of any sort (and for $200, can you really blame them?) and lost power.

      When power was restored, and the machine booted back into linux, the parallel port data bits were apparently all lifted high at some point in the boot process. This, unfortunately, meant that all of the liquor-dispensing windshield wiper pumps were briefly activated. Now, as someone who has hooked a large inductive load to a DC power supply can attest, the momentary current draw of having all of these pumps simultaneously active was not negligible. In fact, it overwhelmed the power supply, but only after a shot of Bottle 1 + Bottle 2 had been dispensed onto the floor. Vodka and rum, I believe it was.

      Now, when the power supply sensed its overcurrent condition (I believe this is how the story goes), it did the noble thing and: rebooted. You can see where this is going: lather, rinse, repeat. The rebooting webmonkey once again lifted its data pins high, once again tripped the power supply overcurrent sensor, and once again rebooted the monkey (all the while dispensing yet another tasty shot of Bottle 1+Bottle 2 onto the floor).

      By the time someone came back to check on the monkey in the morning (a few hours later), the monkey had apparently drenched the floor in vodka, and was still rebooting. I'm told only bottles 1 and 2 were drained, and that the rest of the precious nectar was left intact inside the monkey.

      I'm convinced that nobody who witnessed the aftermath of this event will ever again neglect the power cycling / bootstrapping phase of an electronic device. I don't have a link to it, but I seem to remember AT&T having a similar problem with their switching software across the Atlantic seaboard, maybe six or seven years ago. You can draw your own conclusions, but if I were trying to hire a hardware engineer (not that there's really any other kind, you wimpy IT CS MIS MSCE slashdot derelicts), I'd give much greater weight to their ability to explain the projects they've completed (and the associated lessons learned), than I would to a 4.0 GPA or a Cisco certificate of trainability.

      Mudd grads (math, science, engineering, and other) are presently worth four times their weight in silver the first year after they graduate -- and that's a bargain. They should be worth at least one twenty-fifth their weight in rhodium.

    This is awesome! This has plausable commercial implications. How nice would it be to goto a bar and not have to worry about tipping someone, you just slide your credit card or insert your money and select your drink and you get it in 10 seconds. If I owned a bar I would consider it. After all, the money stuff would be pretty standard to implement, people have been doing stuff like that for years. So say you need 3 for your bar to operate efficiently and you would normally have 2 bartenders working. So you spend $500 a piece on the robots, and you normally pay 2 bartenders $5/hour+tips to work the bar and your bar is open from noon to 3 am each day. That accounts for $150/day in employee expenses.

    Now you implement the robots and your initial investment in them is $1500 and cost to run is literally nothing but electricity. In addition you would need 1 person there responsible for checking IDs and swapping out liquours, so that is say $100/day because you aren't giving the person tips anymore. You've saved yourself approximately $50/day in operating costs which means in 30 days the robots have paid for themselves and you see profits increase by $50/day which over the course of the year is $18,250. I'd say this is a bloody good idea if someone had the resources to market and mass produce this.

      However, this would be illegal or unwise in states where the bar owner is assumed to have liability for the actions of overly inebriated persons. Half of bartending school is how to recognize and handle customers who have had too much. Sad but true, in our litigious society.

      Not to mention that you're a cheap bastard for not wanting to tip :-).

    • This still doesn't make sense, because even a green Linux admin is going to cost you more than 4 full-time bartenders easily.

      You obviously haven't spent enough time in a bar, and have never been a bartender. Bars don't sell liqour - they sell socialization. You already have a self-service bartender, it's called your home liqour cabinet. Most humans go out becuase they want to socialize. They like talking sports with Jeff behind the bar, or flirting with Suzy the cocktail waitress.

      Any bar using these would loose revenue quickly. I've been a bartender, and I can tell you this - a good tender, or a good staff can easily double or triple a bar's income. A bad one can drive customers away. A good bartender makes customers feel good... so they stay and spend more money. If that bartender makes a good enough impression, they might keep coming back and doing so on different nights. A bad bartender makes people go elsewhere. So you can have your robot bar, but I'll stick to my old-fashioned, human charisma driven service model. And come Friday night, I bet my bar will be the one that's packed.

    So now you can punch the monkey, and it gives you a drink.

    And if you are two drunk to punch the monkey, you need to go home.....

    and brings a monkey along with him. The bartender notices the monkey stealing martini olives, sticking them up his butt and then eating them.

    The bartender asks the man "What the hell is wrong with your monkey?"

    To which the man replies "He ate a cue-ball last week. Now he measures everything before he eats it."

    I've always wanted to do little projects like this, where a computer controls various relays. The only thing I don't know how to do is get the computer to control them! Are there inexpensive kits that connect to, say, a serial port? I'd love it if anyone who has experience with similar things can tell me how to do this cheaply.

      Use your computer's printer port - 8 bidirectional lines you can wiggle to make things happen.

      I'd suggest using solid state relays (SSR)'s - your printer port wouldn't drive a normal relay directly, but it could drive an SSR.

      Either that, or use the printer port to drive a transistor, then use the transistor to drive the coil on a standard relay.

      Don't forget to add a snubber network across the relay coil - either a diode or a capacitor. Otherwise the inductive kickback from the coil when you de-energize it could fry things.

      There's a book called Controlling the world through your PC, or something like that. It's old and comes with a floppy disk, but i recall it having schematics for hooking things up to the paralle port. You can wire it directly but you generally want opto-isolators so you can't fry your computer. You can also get a wide array of stuff to interface to the serial port. I like the motoralla 68hc11 microcontroller. It does cool shit (we actually used one in a previous barmonkey prototype), and the evaluation board with chip runs around $100. Try
      Also, the amazon page for the above book: /-/1878 707159/103-7968018-2248661?vi=glance
