In this project I will show you how I combined an Arduino Nano, an LCD, a rotary encoder, three peristaltic pumps with motor drivers, a load cell and a couple pieces of wood to create a crude, but functional Cocktail Machine. Along the way I will demonstrate how peristaltic pumps work and in which way they can work with the other components in order to pump a precise amount of liquid.

[@gloglas]

The moment when you make drinks on party and everybody is like: Who turned on the washing machine?

[@UpcycleElectronics]

End of party: You find someone you don't even know passed out in your washing machine with an empty glass. ...out cold with shoes on?...break out the sharpies Picasso!!!

[@ig_foobar]

A suggested upgrade: after dispensing each ingredient, run the pump in reverse for a few seconds, to empty the portion remaining in the tube.

[@victoriamarotosilva7093]

Another idea; to save some cost in favor of preparation speed might be using just one pump and distribute the ingredients through the tubes with valves.

[@deangreenhough3479]

Cool project. Just a tip, pre drill your holes in the timber, you have a pillar drill. Perfect nails, no splits and you control where the nail goes. Same as electronics, provide a path of least resistance and the nail will follow Good Job on the electronics 🙏

Wood glue, and a little joinery technique would eliminate the need for nails and screws.

[@bur1t0]

AvE's been talking about building a bartending robot for years, and you've just smashed one out in a 10 minute video. I suppose with him it's more about the journey than the destination. Love your work sir.

[@greatscottlab]

Thanks mate ;-)

[@Fwacer]

I saw a group of 4th year engineering students did a similar project to this for their capstone project. Cool! Theirs worked a bit differently in that I think all tubes could run at the same time, no weight sensor. They also added an auto cup dispenser and conveyor for coolness factor.

[@rangaswamy8604]

Thank you. Very interesting demo with professional work. Different constituents can be placed at top and gravity fed into the bottom container. The flow of different constituents can be changed automatically using solenoid valves placed in the discharge line of upper tanks.The load cell can weigh cumulatively and stop in the end.

[@FBRB200]

A very nice project, as always. The only part that doesn't looks very good (for me) are the three tubes hanging there, i would recommend you to get a bigger black tube and put the three tubes into there, thus it will look better. Keep working, you are awesome!

[@greatscottlab]

Thanks mate. Sounds like a good idea.

[@NoHeroez]

GreatScott! Or 3D print a 3 to 1 adapter!

[@MrHandwerk]

Nice Cocktail Machine !

[@recklessroges]

I feel that the quantity and quality of videos can only go downhill from here, after creating such a practical and useful machine.

[@kylepreiksa8183]

Brilliant! For my senior capstone project in college I made a similar system, but it was gravity fed rather than peristaltic pumps. Ours had a fancy QR code based ordering system and inventory management though. I always wondered if we should have gone the peristaltic route, and it looks much cleaner and easier to manage/control

[@legomasterj]

is it going to be 400$ and only be wifi connectable?

[@ABaumstumpf]

And required proprietary ingredient-bags :P

[@Cicirifu]

We require you to subscribe to five monthly deliveries of ten packets of QR-tagged orange juice, so we can guarantee our quality standards and bring you the best experience.

[@veturis3111]

that reminds me of something.....

[@legomasterj]

I wonder what?

[@Kabodanki]

need connectivity to the cloud, because reason

[@krowven]

Would it be worth reversing the pumps for a few seconds after it finishes to clean out the hoses? That might keep the plate clean and make cleanup easier later. It would also make switching to other drinks easier. It's not a screwdriver with cranberry juice!

[@stephenborntrager6542]

That could cause problems if the pumps need primed.

[@bilzoo20001]

I dont think this type of pump needs to be primed, looks like it should be air-tight. but then again I haven't used them.

[@Badg0r]

I'm so going to build this and connect this to home assistant to use our smarthome as a web interface. By doing it this way I can also automate the cocktails when I'm done working in friday and entering the door.

[@cloutgang3951]

My uncle also made one a while ago that works with Apple Homekit/Siri and another app for android. Has a compartment for 50 red cups, 10 bottles of liquor and 10 bottles for soda/juices. Might make one of those as well in the future.

[@gasper5223]

If you re drilling holes in wood it s good to put another piece of wood under it to get a nicer hole

[@dieselgeezer18]

Hail Half life !!

[@Cockalicious]

That's what he said

[@meclucas]

This is an interesting project and I liked your design, thank you for these amazing videos. One idea to add variety to your drinks is to use solenoid valves to control from where the pumps are sucking, this way you wouldn't need as many pumps and the valves are definitely cheaper. Edit: Thinking again, maybe using the valves wouldn't be such a good idea for food safety.

[@greatscottlab]

Good idea. I like it.

[@ianmcnanie6081]

Hey man. You got to apply the solder to the pins as you're heating with the iron. When you put the solder on the tip first, the flux burns away and you get a cold joint. Love the videos!!

That is awesome, i wonder if with 3D printed parts for the case and a little bit more of engineering to account for the vibration so more structure would give a better stability, and a SD Card reader to read "recipe files" would render in a awesome machine. Nice job, i would like the video 10 times if i could.

[@greatscottlab]

Thanks mate and thanks for the feedback. Nice ideas.

[@davidfrau4517]

You could even use some Peltiers and cool the drinks to temperature, that would be cool, and with a bit of code you could easily compute the alcohol percentage and volume in a said mixture of drinks :)

[@imnota]

I've seen a pump like this in a bubble machine, and was surprised by the ingeniosity they used for a simple pump. It seems simple, but I would never have thought of that way.

I'm not the most experienced wood worker in the world. But I would like to give u a tip on keeping the wood from blowing out like you have around the tubes. First, drill nice and slow. Second, but a piece of scrap wood under the piece you want drill. It should keep the good piece from blowing out. Love you work!

[@D.Stekelenburg]

The 5V pin of the L298N is actually an output from the build-in regulator. So no need to hook that up to 5V

[@greatscottlab]

Correct, I realized that too late for the video but changed it in the schematic.

[@areg7182]

True

[@JackyNoTouchy]

Did you get the idea for the peristaltic Pump from William Osman?

[@greatscottlab]

Since I do not know who that is, no.

[@TurboSqu1d]

JackyNoTouchy coincidence? I THINK NOT

[@peepopalaber]

Well the idea to use peristaltic pumps to move liquids is not new ... but it sucks what happend to williams home.

[@IceBox3]

GreatScott! Alter du verpasst was! William Osman ist mega witzig!

[@JackyNoTouchy]

GreatScott! Oh, He made a video using one it was funny. It made me think of some projects

[@BeetleJuice1980]

great idea! the scale measures mass not volume so liquids with different viscosities will give different volumes. you could have one pump and a distributor that changes the liquid being pumped (plus some valves and that way you could have maybe 10 liquids and only one pump , plus you could do a flush to the pipes after each liquid was pumped)

[@raicogonzalez1720]

Wow, really great Scott

[@FlatFace986]

Hey GreatScott! I have a project idea for you: Modify a PSU to be constant current source. I think if you remove the feedback from the output and add a small resistor(current shunt?) to the low side, it could provide a feedback. This should be amplified to the appropriate level and voila CC PSU. I didn't think this through, but I think this could be done, with your knowledge. Would be useful to drive leds, even many in series, since the voltage could go above 12V. What do you think? Cheers

[@greatscottlab]

Hmmmmm I put it on my to do list.

[@gkshighfalutintubeexperien8205]

Why we didn't make an (selling) machine???

[@mustafaerdogan.apriltechnology]

I think instead of recording pumping periods and adjusting poured material's volume accordingly, knowing the densities of the liquids and adjusting the poured amount making use of the strain gauge sensor would be wiser. However, you have done a great job and congratulations for that. I hope you continue making such videos.

[@VMFRD]

From one Electrical Engineer to another, good work mate!

[@En1Gm4A]

it might be possible to measure the liquid on a other way. you might be able to measure the current of the water going through, because it is moveing electrodes it should produle a voltage !! can you do a vid on that ?

[@greatscottlab]

I don't understand what you mean. Sorry.

[@En1Gm4A]

GreatScott! Go on wikipedia and search for magnetisch induktiver durchflussmesser

[@En1Gm4A]

GreatScott! Dass meine ich

[@Algorhythm027]

I'm not sure what you're referring to, but you can't use the electrical current flowing through a liquid to measure the flow rate. To do that would require either a turbine in the pipe or something else that can be measured electronically which is not practical on this scale

[@Rostol]

Algorhythm no, you can do it. It is called magnetic flow meter. Or mag meter. It requires a conductive liquid. The problem here is that it requires a known conductivity on the liquids. Which would mean recalibration after each new liquid is used.

[@MaicahRu]

instead of using a timer you could have used the strain gauge measure the weight?

[@meclucas]

He could, but I don't think it would work as well as it does with the timer. The problem here is that the load cell produces a low signal that is susceptible to noise, in order to read a stable signal you must use some form of filtering, which will decrease the response time of the load cell, so he wouldn't be able to measure the amount of liquid poured in real time.

[@greatscottlab]

Yes, that would have also worked. But the problem was that due to the vibrations the measurements were a bit off.

[@farvizn5721]

how safe is it to move liquid from a pump like that, since you will drink it

[@jeremyhall7259]

Very as you see he replaced it with food safe silicone tube.

[@MrDaniyalAh]

Kartikey Agarwal He used food safe silicone tubes plus no mechanical parts come in direct contact with the liquids, the pumps simply press and push the liquid forward in the tubes

[@greatscottlab]

Correct, like already stated very safe due to the food safe tube.

[@agarceran]

If the tube is food grade it should be completely safe, as the liquid doesn't get in contact with anything else.

[@Rostol]

Very. Peristaltic pumps are used in hospitals for this reason. No mechanical parts come into contact with what is being pumped.

[@MrDaniyalAh]

The scale imo makes this amazing. You amaze me

[@Newjorciks]

Suggestion: When you drill into wood, Drill from the hidden side and also have another wood piece under the piece you are drilling. That way when material is pulled up the hidden side will have ugly sides(Because of wood pulled up) and the good side will have a nice hole because the wood piece it is against will prevent sides from separating on the sides. If you need both sides pretty, then sandwich the piece you are drilling between two other wood pieces and then drill.
