The problem is that you are limited by the thermal conductivity of the pepsi itself. You can only cool it so fast until the outer layers of liquid start to freeze before the heat has a chance to escape from the middle. You should find a way to gently stir it, maybe have it spin very slowly with changing direction.
You can either mount it between your cpu and a good heatsinc, with thermal compound on both sides, or you can buy a unit consisting of a peltier and heatsinc in one.
Another way to do this is to build something similar to the cylinder-shaped fan blade system in a tower fan, but have it capable of wrapping around the can with only a little bit of space on the sides, and then on the bottom have a platform for the can to sit on that can spin with ball bearings so that when the lid is closed, it can grab the top of the can to keep it from spinning yet still allow the fan blades to rotate around it. The lid and can platform will have slits for air intake and the blades will push the air outward...and from there all you need to make it use no electricity at all is a crank that spins the fan blades at a high ratio, perhaps a 8:1 or 10:1 ratio from the crank.
Just a little suggestion: Although there's the episode browser on the top of the videos, you should number each individual video for a better overview. Keep up the GREAT work!
Peltier CPU coolers have existed for years now. You can buy them online. But be prepared for a hefty energy bill, because those eat several hundred Watts of power to cool the CPU and still need a fan to disperse the heat. So such a cooler is a lot more expensive, requires a powerful PSU, still creates noise and costs a lot to have it running. That's probably the reason they haven't caught on. But they're a great option for overclockers where money and noise isn't really that much of an issue.
I'm still using a Coolit Freezone Elite CPU cooler that is based on peltiers on my i7 2600K overclocked to 4.6Ghz & never surpassed 56c even in a 30c heated room & benchmarking. This with it set to only 40% of full potential power, at full potential it easily drops well below ambient temperatures to the point where I have to worry about condensate build up but the software keeps everything in check perfectly. Best cooler I have ever owned including my custom multi radiator water cooled systems.
Ben didn't share with us what power supply he used. At the end, I kinda saw it hooked up to the 24 pin connector of a SFX PSU. Although which connections did he use?
Stir is a verb, to stir. It is not an ingredient. It is when you use an item like a spoon and move it around in a mixture. In this case stirring it would be to use a spoon to mix the salt with the ice :)
easiest can cooler is a bowl of ice and salt. stuff a can in the salted ice and 2 minutes later the drink is ice cold. the salt causes the ice to drop its temperature far below freezing which cools the drink quickly. also, its practically free since everyone has a bowl, ice, and salt in their house.
I like the idea of the Green-O-Meter. It is a definitive indicator of how well designed the project is -- how efficient it is. This is important I think. I converted my HD V-Rod motorcycle to all LED and refused to use wire-wound resistor loads to trick the ECU for that very reason -- it destroys the benefit of efficiency! Buck-Booster controllers well for LEDs. Hey... funny... a pal of mine gave me a USB powered can cooler that works the same way as the can cooler in this video! A fan blowing past the hot side heat sink.
Yes.IR thermometer is reading some of the room heat reflected in the reflective aluminum surface -- you need a contact thermometer. I love these optimal -- overkill designs!! Great!
just an advice to your videos: I'm from germany, so my english is not as good as your, so I can't read your subtitles/ below information as others do. I try to follow your videos as good as I can, but often I have to pause and look back. I would like to see the below informations longer so I can read them through without pausing. I think all foreign countrys will have a advantage from this. Thank you very much, keep going like this, apart from the below information thing. =) THANK YOU !!!!
1 flaw in your design ben, you have to have the heat pipes in the cooler pointing up for work correctly. and the fluid inside heats and steams it rises carrying the heat "UP" to the cooling fins. they will not work properly sideways or upside down. In that orientation, only the copper is carrying the heat to the fins and not the liquid inside.
Incorrect, these are common CPU heatsinks for a pc. Generally, your CPU cooler is mounted onto your motherboard in the same orientation that the ones in the video are.
you can build that OR you can use water, ice cubes, and salt, put them all together in a bowl and mix them, then put the can of soda in the cold water and stir it a couple of times, it will get cold in matter of seconds, more eco-friendly, and without doing all that stuff ;D
An Arduino is way overkill for this. It only needs a simple thermistor controlled voltage regulator circuit. Ben also demonstrated the perfect way to destroy a Peltier. They have to be kept DRY. They should be insulated and sealed around the edges to keep out condensation.
I used to not like Ben, but he is pretty cool since i've been watching over the years. I like these older videos because Ben and his crew seem more relaxed and natural in these earlier shows. Now he seems overworked and stressed out lol. poor Ben
Lol I like this guy a lot. His character is quirky, smart, and idiotic. All the science and engineering is legitimate. The things he uses his awesome powers for is idiotic. lol keep up the great work man!
i beg to ask but how much would this thing cost ? It looks cool but i'm not a electrical engineer, I build computers but working on the electric side isn't for me. I'd really like to know how much something like this would cost.
I have just discovered you on UA-cam! Your videos are excellent and very entertaining. My next effort might be the solder reflow oven. You evidently have a preference for diet "soda" or "Pop".... So I was wondering if you are aware of apartame (artifical sweetener) poisoning. It's extremely toxic. People gain weight from diet soda because it makes them crave carbs. Keep up the great effort and I think that you are a very bright person. Respect from Apache Junction, Arizona.
Also, where do you get your screens to the portable game systems? What screen is best for that system and that system (Amiga 2600 series and PS3 as an example) Also, me and my buddy are thinking of getting a defect ps2, but we cant find anyone, wanna help us find one? We live in Norway, PM for more info. Also, we are thinking about replacing the parts with old pc parts (most of them dont work we think) Is this possible?
Ben wouldn't it of been better to use more peltiers (Pill-tea-A) to get a higher QMax use less voltage and be more green? :D From what I have experienced with peltiers the more you use the more effiecent they get, I used 8 132w Qmax peltiers for a watter chiller in my rig, so I'm speaking from experience.
I am all for MCUs and Arduinos, but why use one in this build? Its a control circuit simple enough to be realized with a simple voltage comparator + a little extra components.
+iver sobakk (jawa master) did you ask a question did he answer you prob not..nice guy but rude pple ask for his advise and dont even rply how rude !!! as viewers i think we have a right to an answer and for the videos he makes he should answer questions,. true ?? its the viewers that drive you tube
I need to use my 240 rad outside tower. Im going to put the petier with noctua heatsink on hotside and cold side ontop of the res then onlt to gpu phanteks cooler block in tower then and back out to loop. Worried if condensation getting inside pc tower but doubt it could. But ill watch but with all outside i doubt it could. If i see any sign ill unplug the pelteir use just radiators alone. Only as have these sitting thought put onto res. Square cheap one. Spare cpu cooler to. Wide channels could go through that with peltier before gpu and back. But unsure if 300lmin is ok. Cheapo pump. Have sc600 but maybe too much.
The ignoring by a sister or family member when you explain how something works is too real! Nice project
I think Alyson just wanted lunch
Best show on UA-cam, hands down!
gotta say hooked on watching these (i might not be able to do this but i love watching random videos like these!!)
Can cooler to take to a park or when ridding bike cool AWESOME idea Ben...
I love the fact he pulls out a 'Luke Warm' Pepsi......from the Microwave. XD
if only i was a skilled engineer i'd rock like Ben...damn!
why do I think that gluing the aluminium together would break even heat transfer
started to watch all of your vids, going to be fun
Tip: If you put a nice layer of Arctic Silver between the can and the aluminum blocks, it will help get your coke colder faster.
The problem is that you are limited by the thermal conductivity of the pepsi itself. You can only cool it so fast until the outer layers of liquid start to freeze before the heat has a chance to escape from the middle.

Would vibrating it, like ultrasound, work?
@@BrainSeepsOut that doesn't sound like a great match for a carbonated beverage

I love watching these even though i know i can never build any of this
This is a good look for Ben, nice shirt/sruff
Can i use this in a computer and set the peliter to never get below 0 and start to condense.
And is there any way to get the partis list and pogram ?
15 MINUTES?!
Might as well put a can in ice, add salt and stir. Due to thermodynamics the can cools in about 2 Minutes!
You can. You can use it to cool a heatsink, radiators, or run tubes along the cooler.
arduino is the best way to get into micro controlling! Thank you Italia^^
Nice stubble, Ben!
this is an irrelevent problem in sweden (is always cold)
7:59 "microprocessor such as the arduino"
noooooo
straight up Nerd stuff but i'm subscribing because i want to learn some stuff and you're channel is great keep it up.
THATS WHAT I REQUESTED :D
I'm always putting cans in the microwave, I like seeing the sparks

you have came to my rescue!!! i could not find a 12 volt 3 amp regulator any were!!! thanks to element14 i have one!!

You can invert the positive and negative for heating. Double functions!

I built a peltier fridge once...but this looks way cooler!
Hey did he just showed me middle finger saying the word stronger? xD
Great show Ben i love it :)
ja, schon krass, da kriegt man fast bock, ein stromkabel hier rüberzulegen und seinen Strom von da zu beziehen!

Can we get the code somewhere? Because i want to build this but is dont have the programming skills to make something like this
how much did it cost in the end to build

wouldn't be too worried, I speak english as my first language and I have to pause it.
So what are the temps of the cola before and after?

pepsi diet:Ben's favourite drink
what did you use to power the can cooler in the beginning? What is the name ov that thing?
An add-on for putting more drinks.
FIFTEEN MINUTES.... but I want my cold cola NOW!
I would use this to cool freshly pressed orange juice
I really need to get a CNC machine like his lol.
4:40 Water+Electricity, Great Mix
can peltier be used for cooling cpus on a pc ?
you can build that OR you can use water, ice cubes, and salt, put them all together in a bowl and mix them, then put the can of soda in the cold water and stir it a couple of times, it will get cold in matter of seconds, more eco-friendly, and without doing all that stuff ;D
can you use it as a external cooling for a laptop?
How long does it take you to freeze water every time you want to cool a can? Hours, when you factor in everything this is quicker and MUCH cheaper.
Any chance you could put the cnc files up for us to access/download? I want to do this but will get a local shop to cnc the aluminium can holder bit.
Those heatsinks are so strong that the can will be cooled faster without those thermal diodes ;)
eli hatamov Heatsinks cool to room temperature, not lower...

LOL cool intro

I can't imagine that JB Weld makes a good heat sink paste.
My comuter is laggy "Today we're building a P-Pills here"
i beg to ask but how much would this thing cost ? It looks cool but i'm not a electrical engineer, I build computers but working on the electric side isn't for me. I'd really like to know how much something like this would cost.
you can buy the mosfetts very cheap (like 2 dollars), the arduino nano is pretty expensive (you can buy them from chinese sites for much cheaper)

I also have an end of stroke switch.
I want one.
Just an idea but it would be great if you had something like references with parts lists with prices for projects like this one.
which machine is that at 3:32 ?
Depends on how its implemented...
"I'll just use this blow torch, YEAH!!!"
You can!
can you use this on a cpu?
could u integrate a cellphone into an old rotary phone so that the rotary phone is usable but as a cellphone?
@ 15:00 was a reference to an old Arcade game :)
I plan on building a hidden refrigerator inside an old computer case using those
Also, where do you get your screens to the portable game systems? What screen is best for that system and that system (Amiga 2600 series and PS3 as an example) Also, me and my buddy are thinking of getting a defect ps2, but we cant find anyone, wanna help us find one?

9:38 totally looks like Jake Busey off of Frighteners
is that a hyper 212 cooler
you say it doubles as a room heater but if its heating on one side and cooling on the other wouldnt that technically make it an equilibrium
Nothing is perfect and you are using electricity for the Peltier effect. The byproduct is more heat.
Your sister is cool. I mean... Bring her back for another episode!
Sorry to burst your bubble but there's no relation :)
The Ben Heck Show Are you From Wisconsin
I built a similar thing a few years ago, but i used a 140w cell and ended up freezing part of my cola... :)
you're from Wisconsin and say pop?! I'm originally from there and I say Soda!
17:39 He's flippin us all the bird and none of ya even caught it
If you really want to cool a pop quickly get a bowl put ice water in it with a good amount of salt and stir. In no time it's nice and frosty.
Howard Wolowitz, is that you?!
Ben wouldn't it of been better to use more peltiers (Pill-tea-A) to get a higher QMax use less voltage and be more green? :D

Yep, a simple electro-mechanical thermostat would've done the trick. Or a cheap electronic temperature controller.
The Ben Heck Show where can we get the code, and the list of things you used?
+iver sobakk (jawa master) did you ask a question did he answer you prob not..nice guy but rude pple ask for his advise and dont even rply how rude !!! as viewers i think we have a right to an answer and for the videos he makes he should answer questions,. true ?? its the viewers that drive you tube
15 minutes? Put a thermometer in the can of soda to see how quickly it cools.
Submerging a can in icy cold water is faster.
I need to use my 240 rad outside tower. Im going to put the petier with noctua heatsink on hotside and cold side ontop of the res then onlt to gpu phanteks cooler block in tower then and back out to loop. Worried if condensation getting inside pc tower but doubt it could. But ill watch but with all outside i doubt it could. If i see any sign ill unplug the pelteir use just radiators alone. Only as have these sitting thought put onto res. Square cheap one. Spare cpu cooler to. Wide channels could go through that with peltier before gpu and back. But unsure if 300lmin is ok. Cheapo pump. Have sc600 but maybe too much.
or you can wet a paper towel and wrap it around the can. toss it in the freezer and in 15 min it is starting to freeze.
You can, but where's the fun in that? If you want to do that, fine!
All you need is salt, water, and ice. That's it.
man i need a cnc
U forgot about the lights and how much power it took to charge the camera and heating
And now we can buy a spinning version. It's called the Frost Boss. I still like Ben's better.
You Should Do A Episode With Dave Jones
Freezer takes longer. Also, it's because he can.
DID you Flip ME OFF there BEN!!!!!!...........
The peltier is probably overkill... The heat sinks and fans would be enough...
notice how the atari 2600 in the intro has rca cable mod
