Introduction: Single Serving Ice Cream Maker

Picture of Single Serving Ice Cream Maker

Homemade ice cream has a unique taste which simply isn't duplicated amongst commercial brands. Add to that the large number of flavors one can make, the sense of accomplishment through all things DIY, and of course enjoying your creation and you have a winner with ice cream made at home.

Warning: It has been brought to my attention that only food grade plastics should be used for a project such as this. For this tutorial, that would basically mean replacing the spindle with something designed for use with food. You can never be too safe- especially if you have kids.

Step 1: Gather Materials for Ice Cream Maker

Picture of Gather Materials for Ice Cream Maker

There are really three major parts to this, all of which were found in my home. The most important part is the electric motor which can be salvaged from any number of electronics. This particular one came from a non-working disc drive and the motor was used to open and close the tray. I left the gears attached and just cut the plastic around it so everything stayed intact. Also needed is an empty jar of peanut butter with the lid, and a 100 recordable DVD casing, which needs to be the type where the spindle unscrews from the base as opposed to the type where it is fixed in place. You'll need a few other odds and ends such as a little plastic ring from the stack of recordable DVDs, some cocktail straws, four pieces of short (3-4 inches or so) galvanized wire, and something to secure the motor down later in the process.

Step 2: Make Some Modifications

Picture of Make Some Modifications

I was lucky enough to have the electric motor already mounted to something usable, so we'll forget it for now. To start with, I drilled four evenly spaced (eyeballed) holes in the peanut butter jar on the neck of the bottle. I then cut four notches in the DVD case to correspond. Not too deep, just enough you can hang a piece of wire over the edge without interfering with attaching the base again. I then ran some wire through the holes and hung the peanut butter jar inside the upside down DVD case. Finally, I used a hacksaw to cut off the threading from the spindle so I could glue the gear directly to it.

Step 3: Make the Spindle

Picture of Make the Spindle

I drilled some holes in the spindle, and cut the cocktail straws to where they would fit into the peanut butter jar, then inserted (without glue) into the spindle. Nothing inside the jar should contain glue, and more importantly SHOULD NOT CONTAIN SOLDER! A lot of solder contains lead, which is bad, as any self-respecting pirate could tell you. Next, cut a hole in the peanut butter jar lid large enough for the spindle to freely turn, but small enough to help keep it in line. I took the spindles out, added a plastic spacer/washer to the spindle, then the peanut butter jar lid, then the DVD base, and put the cocktail straws back in. I glued the peanut butter jar lid to the base to hold it in place, then once again made sure everything fit. Oh, I also cut the spindle to peanut butter jar depth.

Step 4: Add the Motor

Picture of Add the Motor

The largest gear that moved along grooves in the disc tray hung out further than the other gears, so I glued the spindle directly to that gear. I also drilled a small hole in the side of the black base and the electric motor casing to tie down the motor and keep it from just spinning on top of the ice cream maker. It would probably be better to actually secure it down, but this worked and I went with it.

Step 5: Something to Keep in Mind

Picture of Something to Keep in Mind

I gave this a short test and it worked for a few seconds, then stopped turning the spindle. After some CSI work, I discovered the screw holding in the last gear had got glued to the spindle, and caused the gear to become unattached, thus not turning the spindle. I took it apart, and just made sure not to get glue near it the second time. Then I put the spindle back together and tested it again to make sure everything was working smoothly.

Step 6: Prepare the Ice Cream

Picture of Prepare the Ice Cream

There are lots of recipes online for making your own ice cream. After a little searching, I went with this instructable:

The main reason was because it was for a small amount and would translate well to my project. I mixed in a cup first, then transferred it to the mixer. For illustrative purposes I went with the chocolate mix, and did not use ice/salt like you normally would. I did include ice melt in the pic because I thought it would be something people may already have on hand and use in place of the salt. However, I don't really know off-hand how toxic this would be if it happened to get in your body.

Step 7: Set It... and Forget It!

Picture of Set It... and Forget It!
Ala Billy Mays... add the top on to the mixer, and I used a AA rechargeable battery to power the motor. A little electric tape and put the corresponding wires on each end of the battery. The mixer should start turning as you do this. Take the mixer and place in the freezer. I'm not sure how long a battery would power this. At first I was checking it about every 15 minutes to make sure it was still powered and still operational. After the first hour I went to half-hour check-ins. After about four hours in my freezer, the spindle slowed down significantly. I'm not sure if this was a power issue, or because the ice cream was much thicker. I thought it looked ready from the outside, and tore everything apart. In retrospect, it needed to be left in a while longer, maybe with a fresh battery.

See it in action!

Step 8: Enjoy... Then Refine.

Picture of Enjoy... Then Refine.

I dipped out quite a bit of the ice cream and then poured out the rest... it clearly wasn't done setting. I still enjoyed it, but it didn't really remind me of ice cream as a kid either. First, I made way too much for just myself. Secondly, it needed to be much thicker, added to the fact that I had never had homemade chocolate ice cream, only vanilla or some fresh fruit variety.

I think this has a lot of potential though... if I had used ice and salt instead of just the freezer, I'm sure it would have set faster and better. The paddles probably also need to be thicker to keep a lot of ice crystals from forming, but it's hard to tell from this batch. Finally, I think I would prefer the vanilla instead of chocolate (a little chocolate syrup really helped the flavoring though).

Overall, this was a pretty satisfying project, and I think the more someone did this, the better results they could get. This project is also entered in the rechargable battery contest, so if you enjoyed it please remember to vote. And, if you guys try this, please drop some pics and let me know how it turned out for you!

This is an awesome idea. The biggest improvement I have is to build the spindle out of a second peanut butter jar, so you have food-grade plastic, and you can cut portions of the wall out, cut holes in them and build nice big paddles to really break up the ice cream. This would get it a lot closer to commercial ice cream makers. Ideally the freezing should be done in about 20 - 40 minutes. It should be a uniform thickness ( I think the paddles will help with this ), and then you can freeze it normal for a few hours without any mixing necessary. Thanks for the great instructable! I am going to try this if I can get a chance to do it.

MushiiiW (author)suckrpnch2016-05-17

Yes Its really great think thanks admin but I also suggest you another New maker which have updated features :)

yokozuna (author)suckrpnch2010-11-29

That's actually a really good idea, using a second jar as the paddle. Also, I think if I had used ice instead of trying to just stick it in the freezer it would have been fine. Thanks for your comments.

AxcellaZ1 (author)2017-10-05

What about using a large Mason jar, with the sealer lid and another one for the inside. I would suggest a Starfrit spinner blade, plastic for the mixer. If you can try doing it that way I would love to see if it works. I am great at ideas and solutions but not on the technical or assembly.

yokozuna (author)AxcellaZ12017-10-14

I like the mason jar idea, though I was really just using what I had available at the time.

mohamed4data (author)2016-07-10

This is an awesome idea ...good luck

ladybanksia99 (author)2010-07-08

My thought includes the need for some sort of scraper, as is used in conventional ice cream makers. Hhmmmm... ...maybe modify some sort of spatula that could be shaped to follow the contours of the peanut butter jar so that it could scrape the sides of the jar as it freezes. It may make it a little too much work for it to run on the battery source; therefore, needing to be hard-wired for electricity. Are the cocktail straws strong enough as well or do they bend back as it turns? This is a great project!

yokozuna (author)ladybanksia992010-07-08

Thanks. The cocktail straws seem to hold up fine, but I think you're right. Long story short, even with some improvements there is still a good deal of crystalization as it hardens. I'm not sure what the answer is... freeze quicker, turn harder, or what.It's not terrible, but it's not awesome as I had once hoped. I guess it's back to one gallon chocolate tubs for the time being. :)

pearlheartgtr (author)yokozuna2015-09-20

I know it's been a while since this instructable was posted, but have you considered McDonald's coffee stirrers? They have a paddle on the end of them.

yokozuna (author)pearlheartgtr2015-09-27

I haven't- but I did try plastic spoons. They seem to work very well.

coniosis11 (author)2012-03-28

..Can I put the motor directly without a gears?

yokozuna (author)coniosis112012-03-29

It would turn way too quickly. Keep the gears, they're always there to slow the CD tray down.

coniosis11 (author)2012-03-28

..haha.... if you will make your cellphone battery as the motor's battery,Your Ice cream maker will be also called a blender so you can now make a FRUIT SHAKE in this summer !!! enjoy.... ask me if how to make a fruit shake.. ( with evaporated milk)

docz (author)2011-09-07

Shouldn't you put ice and rock salt into the DVD case? If you have trapped air between the freezer and ice cream mixture it is going to take forever to freeze.

HamenChips (author)2011-06-01

One tip is that you don't have to put that inside the fridge for so long you could put some ice in the CD container (make it has salt) then turn it on, that should take about 20 minutes or so.

KenzieTheGoodShot (author)2010-12-11

I used this for a school project. In my technology education class we were able to choose something to construct, I chose this, I showed my techer where I got the idea and he loved it. Thanks!

Cool... hope you got a good grade, and I would love to see pics if you have any.

suckrpnch (author)2010-07-29

After a decent soft serve or milk shake consistency is achieved, you could freeze the ice cream in the freezer for 2-4 hours, and it should reach the final thickness you are looking for. Seems like most home and commercial ice cream makers still require this last step of freezing to get the best final results.

Clearly, "Set it, and forget it!" is a Ron Popeil saying. ;-)

By the way... think Ron saw this and murdered Billy out of jealousy? You know how those Hollywood types can get!

yokozuna (author)mikesum322008-11-20

True... but have they ever been seen in the same place at the same time? Me thinks not.

souichi (author)2010-02-08

this idea is great it is not to expensive and it is eco-friendly

Riojelon (author)2009-12-07

I constructed one out of my old hand held mixer as the motor, some powdered milk cans and a plastic bottle. I don't know yet the taste of it but I'm sure my siblings would love it . . .

kalabog76 (author)2009-10-13

hmm... instead of batteries, a flat wire would do connected to a 12v DC power source ...

Nice what you did with gears, lower gear ratio should provide enough torque to stir the ice cream when it is almost hard.

Yerboogieman (author)2009-08-27

Sooo, whats the CD case for? Can't you just add the motor to the PB jar? Unless you add ice to the CD case..

yokozuna (author)Yerboogieman2009-08-28

the CD case is for the ice and salt, just like a normal ice cream maker. They were left out here, so you could see the process throughout each step.

Absol (author)2009-08-09

Your idea is pretty interesting.... Yay! Hooray!

yokozuna (author)Absol2009-08-28

Thanks, welcome to instructables! :)

mag400 (author)2009-08-02

Well. It seems like a great instructable. However, here are some bits of helpful advice. Firstly, you could fill the DVD container with ice and then add in salt. You'd have to maybe pull out the PB container when serving tho, unless you want salty ice cream. That also solves the problem of the batteries losing charge, since you can leave it out on the open and the batteries arent exposed to as much cold.

yokozuna (author)mag4002009-08-02

In step six, I stated the lack of ice (and thus putting it in the freezer) as well as choice of chocolate ice cream instead of vanilla are for illustrative purposes only. Otherwise the space between the pb jar and cd casing would act as an insulator, preventing cooling. While maybe not stated or shown, the peanut butter jar does come out in order to serve it.

Asura-Valkyrie (author)2009-05-01

Hmm, one thing to remember with batteries and cold temperature is that battery efficiency can vary and can go down as much as 70% in colder temps (I believe with NiMH and alkaline batteries). Lithium tends to do alot better in the cold but can also be pricey. I wonder if you have one of the former batteries mentioned, I can't tell from the pictures, other than it is an energizer battery. Of course it could be a combination of things which you have mentioned already.

Here is a nifty battery guide that I just found online :

Is it possible to mod this and make a hand cranked version?

yokozuna (author)CerealKiller2009-04-26

Naturally... but you might just check into modding old 1-4 quart glass jar butter churns instead.

Thank You.

This is awsome!

HappyToBeAlive (author)2008-11-21

stop being such a worry wart, for gods sake, most people inhale worse fumes walking to work than they would ever get poisons from this Ice cream Maker. Get a grip Dude!

123456 (author)HappyToBeAlive2008-11-21

"worse fumes walking to work..." This is not true at all. You obviously have no idea the odds you are taking on foolish pursuits such as this. The chance of cancer, kidney/liver failure, and other diseases skyrocket when using general household plastic. Plastic is literally petroleum it must be specifically formulated to be non toxic. There is nothing to debate here. If you use toxic products with your food you will pay for it with your well being. If you even think about giving contaminated food to a minor I challenge you to post evidence of this. In most states (of the USA) this is a clear case of child abuse and I will have social services explain it for you.

Mig Welder (author)1234562008-11-21

If you will notice the author is using a peanut butter jar, which last time I checked is a food. Therefore they are using food grade plastic. The CD case should not be making contact with the ice cream if done correctly.

yokozuna (author)Mig Welder2008-11-21

Actually I think this is a fair criticism. The cocktail straws and peanut butter jar should be fine, but I would suggest replacing the spindle with something of food grade plastic. I've been searching for something that can be made into more of a "paddle" anyway, thus avoiding the spindle and straws altogether. I'm open to ideas on the matter. With that said, I did eat this and didn't die, but that probably shouldn't be your standard either.

oakironworker (author)yokozuna2008-11-29

imagine yourself eating the whole spindle. Would that give you cancer? No make you sick? nah funny looking stools maybe. Now imagine you got a few atoms of the plastic from stirring your ice cream. will that make you sick. Only if you worry about it. The stress of worrying is a killer. relax

Mig Welder (author)oakironworker2008-11-30

hahahaha! funny looking stools lol!
