I fix coin sorters for large grocery stores. The dirtiness of coins cause issues even in the best sorters. The best coin sorter i have worked on uses a rotating near virticle rubber wheel to get the coins on their side, then it will sort by height by knocking the tallest off the track first then getting smaller. Hard to explain in a KZfaq comment. Great first attempt

Because dimes used to be silver, whichnisnworth more than copper and nickle, so a smaller amount is more valuable.

For the problem with the coins getting stuck maybe take away the turn since it's losing a lot of it's momentum while going into that turn. And maybe add some sort of power function system that is able to vibrate the actual sorter so that even if the coins do get stuck they'll eventually fall into the desired slots. As for the coin being on top of each other maybe you could have some sort of system that will allow only the thickness of one coin to go into it although this could pose a threat to the machine being constantly jammed. I hope you develop this project further as I don't see too many coin sorting machines out of lego.

Why the fake build in the thumbnail

Now make a machine to sort legos. Out of coins.

If you look at the Japanese ticket machines or tills, you may find some inspiration: you can throw money inside and the machine will perfectly count the money and also identifies the ticket you are using in-between the coins (for machines in buses, where you throw the money and ticket all together before exiting the bus, to demonstrate you paid the fare). Anyway, it's basically a funnel, but designed in a way that the weight will not jam everything.

The coins are stacking because they climb over the ones that are stuck. Keep them from getting stuck. A small motor with a counter-balanced weight on the end can be used for a vibrator. Tilt the assembly slightly vertical more yes, but with the angle you need to get them to roll by themselves you will not have as much help from gravity, they will most likely have too much speed and roll right past the hole. As someone said, put a funnel and take out the turn. I would add the vibrator to the finish line of the assembly and a tapered gate with fingers at the bridge from the funnel, preferably with flexible material to help reduce jamming.

If you say the half-dollars are huge, image the ike dollar (eisenhower dollars). They were the dollar coins before the sacagawea dollars and the small presidential ones. They were twice the size of half-dollars (in weight). Also, dimes are the smallest because before, they were worth their weight in silver. So the weight of the coin was the value. However, for pennies and nickels the metal was not the same.

Most coin sorting banks don't sort by value. They sort by size. So the dime would be the first bin while the 50¢ piece would be on the end.

Coin sizes were set when it took $0.10 of silver, pennies were made of copper and the size was the amount of copper to equal $0.01. The Nickle was how much nickle was worth $0.05. And so on. Now none of the coins are made of solid whatever substance, and it costs far more to make a penny than what it is worth.

One of my first custom LEGO builds (i.e. not following instructions included in a set) was a coin sorter that could differentiate between 2€, 1€ and 20cent coins. It worked flawlessly and is still standing as part of the wall of a little LEGO house in the attic in pur house back in Germany.

Oh man this is the kind of project I like doing with patrons at my library (mostly kids but I wish more adults would get into it too - my programs are designed for certain age ranges but all of them are open to all ages). Yeah I've decided. We're gonna do this project for one of our lego clubs.

Great video, but please don't use click bait thumbnail

Where's the scene from the thumbnail?

ill do my best to explain why the nickel is bigger then the dime. in the early days of the usa, the coins were worth the metal content, so a dime was made of 10 cents in silver, etc. and we had a half dime, whih was smaller, but worth 5 cents, and in 1866, silver was going up in value, so we moved over to making nickels, which were worth 5c in nickel, im glad this guy isnt sorting the 3 cent pieces and the 2 cent piece. that would make it a lot harder. nice sorter, gets a sub from me

The sizes are exactly proportionate from when they were silver. A silver quarter weighs 2.5 times more than a silver dime. A silver half dollar weighs 2 times more than a silver quarter and 5 times more than a silver dime. A silver dollar weighs twice as much as a silver half dollar, four times as much as a quarter, and ten times as much as a silver dime. Pennies and nickels weren't silver, so their size was not dictated by their weight.

For an autofeeder if you have a box with a spinning part in the bottom, like a stirring to push them onto the slide part. Maybe a slightly angled ledge above the pusher so a few fall down there at a time so they weight doesn't just jam the whole thing.

I came here before you finished and yes I agree, you should have it so they roll more vertical instead of sliding.

The video had everything except the thumnail

Maybe use Lego motors to add vibration to a coin hopper and make the exit only one coin thick?

Something like this would be neat for an actual Lego set. Minus the Dollar and Half-Dollar, who even has those anymore?

Maybe a light spray with silicone oil and polishing off with a clean, lint-free cloth might help getting the coins down the ramp. Also, a small battery-powered vibration motor connected to the ramp might be helpful as well. Just some thoughts from somebody who tried something similar for Deutschmarks... 😄

I’d make a ramp leading up to the coin inserter which would also add momentum but still sort them on by one.

My pride and joy as a kid was a candy machine that wouldn't work without the right coin.

You should definitely build a cool and uniform outer-casing for the internal machine (everything you’ve already built) housed within a cool Lego box. You can even include snot brick character elements to enhance the look. Another idea would be to implement a way to add empty coin rolls to be filled by your Lego sorter just like real ones do. Overall INCREDIBLE build. So amazed and impressed!!!! Keep up the incredible work!!!

To help with coins getting stuck down the ramp, try rubbing paraffin wax, or a candle, on the ramp then polish it off with a clean cloth. Good job on the sorter!

Dimes and dollar coins are smaller than coins that have a lesser value because of a desire to maintain a scaling property between dimes, quarters, and half-dollars. Each of those 3 coins contains the same blend of metallic alloys (the other coins are different blends.) Further, each of these three coin's masses scale exactly with their values. I.e. a half-dollar has twice the mass of a quarter and a quarter has 2.5x the mass of a dime. That way, any given weight of dimes, quarters, and half-dollars has a set value, regardless of the mix of the coins. If you had some amount of those three coins, any equal value substitution corresponds to an equal weight substitution. You can take a half-dollar from your pile of coins and replace it with five dimes and the value and weight of the pile remain the same.

It kind of defeats the purpose of sorting coins if you have to put them in one at a time. Still, very cool. Good work!

A working coin lego sorter would be much more impressive 😅

Make it drop into a bigger container so that there is space for more coins, make the whole system less compact and make more room for the slides that move them around, put the whole thing on a shaking platform to force them to glide even when they are dirty, and it should all work 🤗 Then add a feeder 😉

I respect the random colors

cant lie this was a fail

thats cool! maybe change the tubes to drop into containers so coins wont jam

This reminds me of my old LEGO projects when I had a huge box full of LEGO. Did very similar things. I vaguely remember doing some coin sorter too.

If you want to input a bunch of coins at once you should make a slanted spread plate, where you dump a few coins on and spread them out by swiping the hill of coins around, when they're flat they can slide into a slit at the lowest corner to go into the sorter one at a time. And I'd recommend you make it a rolling sorter, because I built one some years ago and it sorts the coins while they roll down a ~45° slope and lean against the wall of the completely-vertical, 1-stud-wide channel. I got them all leaned on the same wall by letting them slide down a short ramp into the sorting channel.

The government is trying to trigger my OCD with the size of the coins

Huge props for using a Pick-a-Brick cup to hold the coins. Also, I wonder how many people who weren't already familiar with the concept of Studs Not On Top thought, "What's a snot brick?"

As a child, I've tried something similar, but using weight to select the different coins. But I also struggled on sorting them by value and having multiple at once...

I would put a bar across the top to make sure coins dont stack on top of each other when sorting, (like the height of 1 coin) that's how some coins were able to bypass thier respective slots.

I built one about a decade ago. My needed extra engineering because I didnt have technic or snot pieces. I cant dump a bunch in, they have to be fed one at a time, but it never jams, never gets stuck, and never sends a coin in the wrong chute. If you'd like to see how i did that let me know. I later made one out of wood based on the same concept that I actually use. The lego one sits in a cabinet.

You should add a motor that vibrates the set to help with the movment with coins

I love how a coin sorter is the one that replaced your most viewed video.

Amazing bulid with Lego! it may work better if make it a more vertical so the coins could roll and reduce the friction

In some of coin sorter, the machine vibrates to avoid stuck coins. It's the same as you slam the desk with your hand.

Its because dimes, quarters and half dollars used to be silver, not the regular copper-nickel alloy.

This is impressive because it sorts by size, but then ARRANGES them by value.

the reason it started having issues was probably less about the coins being dirty and more about the overall weight of the system stopping it from shaking and letting the coins move more freely . you could test again with it emptied out and see if it starts jamming around the same volume

12:23 When your science fair project stops working...

Reminds me of this book I used to have when I was younger, where it showed you how to make 50 lego machines. It was awesome.

The reason why dimes are so much smaller is because dimes used to be made of silver, which was much more valuable than the copper or nickel that pennies and nickels used to be made of.

Something like this need to be a set it would sell, as a kid I remember thinking coin sorters were fascinating for some reason.

Nice work! I also made one a while back, the 5C and the quarter were also very close in diameter haha

Hi! Can you put the instructions for the build please?

You don’t have to pay for coin sorters😂

First video, Thoughts : His Neighbors Think He's Insane For Sure

Coins sliding over the Legos may be abrading the polished finish of the Legos, causing friction

For batch sorting, I would have a gently slopped shelf in the shape of a Y which funnels coins to drop off the edge vertically onto a ramp so they then roll down the ramp towards the sorting holes. There would need to be some way to vibrate the shelf so that the coins slowly trickle forward.

This is a pretty good attempt at a coin sorter, I think if you use gravity better and tilt the slopes further and more steeply, most of the issues of things getting stuck are solved. Also, making a curved path for things that have to go round, instead of slopes falling into slopes will lose less momentum, a sort of playground slide if you will, then getting the whole contraption higher up and having bigger containers will make sure there will be no clog of coins at the bottom. Lastly, having a more stable base shouldn't be too hard to accomplish, the whole thing looked pretty flimsy with the awkward angled legs. This was a fun experiment, thanks for posting it. It might be a fun idea, if you have the time and are willing to re-iterate on your design and make a second or third build after this, trying to fix the issues that you encountered. The whole idea of making such a project is improving while you do it and I think you did a great job at mentioning the current flaws. Also, as a general rule for a LEGO channel, having a nice looking color design is a huge plus. Just invest in the most common bricks in 2 or 3 colors, so you can at least build something that doesn't look haphazard. I'm not a huge brickowner myself, but for such a relative small build, it shouldn't be too hard to get something done in one or 2 base colors. Then again, don't take the criticism too harshly, this was a great idea and some very smart solutions for a functioning first design!

With the dirty coins it feels like the gambling game where you have to add coins to push coins to get coins

Coin slide sorters do get dirty because of the dirty coins. So you have to clean the slide often. Sometimes putting baby powder on it will help for a while but really, it is hard to avoid it getting gunked up if you use it often.

What if the mechanism was rotated in degrees? Then the coins would roll around their circumference but still have a 2% angle for gravity to feed them through the slots.

Forgot Eisenhower dollars, Susan B. Anthony dollars, mercury dimes, a whole bunch of denominations.

Have you ever been to a planetarium? They tend to have a black hole simulator you can run coins on. When it gets to the bottom the coins are moving flat. Coins also don't pile up on each other. If you find a way to use centrifugal force, you might be able to sort multiple coins at once. Try using clear pieces. It will make troubleshooting easier. Maybe make the chambers round so the coins land flat.

Penny:oo a free candy van Penny:yeyyyyy WAIT NO MY HOME SOMEONE HELP I BEEN KIDNAPPED

Old pennies are heaiver because they were made out of 95% copper while newer pennies are made of copper plated zinc. In 1943 the us switched to using steel because of a copper shortage. However a small amount of copper was left in the machine and a small number of 1943 copper pennies where printed. In 1944 the us switched back to copper pennies but again some steel was left in the machine and a small number of 1944 steel pennies were printed.

The reason the dime is smaller than the penny and nickel is because the dime used to be made of coin silver and it was once 1/10th of an ounce of coin silver (an ounce being a dollar of silver). Pennies were once entirely made of copper and were valued at a cent and a little bit over (the extra amount of the penny value was supposed to help pay off the national debt). Nickels are (perhaps unsurprisingly) mainly made of nickel and zinc. The quarter was also intended as a silver coin and once had a weight of 0.22 ounces. (being slightly less than a quarter ounce of coin silver). The Kennedy half dollar was originally a silver coin having a little bit over a third of an ounce of coin silver. Of course, today's coins do not have anywhere near the same intrinsic value in metal as most coins are now entirely alloys of nickel, copper, and zinc.

If you have them flip an roll on ther side you could make it more efficient and save space for sorting

POV: You get click baited

Looking forward to a more reliable version of this if you plan on making one in the future! Maybe make a color scheme, more reliable storage, and coin sorter on top??? 🤔

Make a claw machine with Lego people in it 👇

I would add a motorized agitator to the top tray, should help the coins feed better - every coin counter/sorter I've used has them.

Did anyone notice that when he said “make sure to like,subscribe” the subscribe button corners turned rainbow?

Cool. I had a coin sorter that sorted them into cylinders that were the same size as coin roll papers. I don't really interact with physical money much anymore.

I always wanted something like dis but i dont have enough pieces..😢

For the dirty coins problem, just add soap and water to the slide to make it slippery.

only real brickstudios enjoyers can like this comment

The old half dollar coins are about double the size of the current ones, had two but lost one

Track should be oriented vertically, with a slight slant backwards, to guide the coins into their correct chute. That's how older vending machines operated to deal with dirty and corroded coins.

What I'd do is create an initial drop that creates a little more speed, so that the coins have enough momentum to make it to their slot.

Oh my gosh!! You are amazing. Great job.

No coin sorter (that I’ve seen for home use) is perfect. This looks like it works pretty decently. One change I would suggest is to make the entire thing taller. This will give you more room in the individual bays to hold more coins. Maybe you can tune it so that each bay holds exactly one roll of whatever the coin is?

If you wanted no other coins in an area, get a cheap vibration system to help

The coins could be guided past the traps on a conveyor belt and a scanner pushes the coin into the correct opening using flaps.

So many people here offered there solutions! Great teamwork all around! 😀😃😄👏👏👏

For comparison here is the sizes of UK coins, from most diddy to most big: 5p, 1p, 20p, £1, 10p, 2p, 50p, £2. Seems completely random. However, some coins have actually changed - the 5, 10, and 50p coins all got a redesign to make them diddier. The original versions went like this: 1p, 20p, £1, 5p, 2p, 10p, £2,, 50p The next thing to consider is metal. Although these coins were WELL after the age of making coins from valuable metals, the alloys used were chosen to imitate the old metals: Copper/brass - 1p, 2p. Fine Sterling Silver - 20p, 5p, 10p, 50p. Fine Bullion Gold - £1 Which leaves only the 20p, as this coin has its own history. When decimal coins were introduces in 1971, the denominations were 1/2p, 1p, 2p, 5p, 10p, 50p and pound. In 1982 however the 1/2p coin was discontinued as worthless, and replaced by the 20p coin. Before, all the other coins apart from the 50p were round, and the 50p was a heptagon. They decided for the new coin, as it was the 2nd most valuable 'silver' coin to the 50p, to make it a 'baby' 50p, so it was introduced as a heptagon like the 50p to distinguish it from the other round silver coins. Unlike most things between the US and UK, US current coins have a lot more history behind them and so I presume they will have similar reasons for the sizes.

The easiest solutions i could think for the three problems you have are: A lego pouring cone to allow multiple intake but exit of one coin at a time. Allow the cone to rotate so if something is stuck you rotate it and it resumes 2) increase the inclination or add the technic mini wheel instead of just tiles. That might make it a bit thicker. 3) to improve performance pass the coins two times from the sorter instead of once that will help if coins are one over the other

Idea: Extend on the slots where the money goes by attaching containers for them to drop in, because you can’t fit much in how it is. You would obviously need to secure it aswell.

unrelated, but am ithe only one who hasnt heard of a half-dollar??

Ok, that’s coins from United States. That sorter can’t sort coins from Singapore. Hopefully the video doesn’t offend whoever lived outside United States.

Some reason this was an algorithm recommendation, enjoyed the process of seein a master and the craft

This is one of the coolest things I’ve ever seen

This sorter should be looked at as “Mark I” and it should be worked on, or updated, in several stages until it’s near perfect, IMO.

Just put a cover over the sorter so that no coin gets into the wrong hole with another coin.

What about the silver dollar, twice the size of the half dollar

After buying all these legos you won't have any mony left to sort.

make is so that there is a hole in the bottom of a tube/cylinder and the coins drop onto a platform. There is a sliding thing on the platform that pushes the coins into a seperate chute where it falls into the sorting mechanism. This is the simplest way I can think of, and it allows the coins to enter the sorting mechanism one by one

As someone that works in software development, this whole video hits too close to home

Right now you can fix this using gravity you can make the coins sideways it a really good idea, you want to make most of them drop down not in an angle, SO you can make 1 of the coin go around another instead of 2 switching with another this makes it more consistent, and reduce jamming problem. If you can make a thing more simple, do it. complexity is harder to do and comes with more problem.

why does this remind me of a vending machine

The dime is so small because dimes, quarters, and half dollars are all descended from silver bullion and have the same density: 22.68 grams per dollar. The half dollar (11.34 g) thus weighs twice as much as a quarter (5.67 g), and five times as much as a dime (2.268 g).
