Hello everyone! I have been planning this project for a while now: Coin Sorter Version 2! This sorter has many new features and improvements over Version 1, including:

  • Faster sorting
  • Easier to adjust for different coins
  • Choices of how to take the coin holders out and easier to replace them (more info in Step 7)
  • No longer uses a motor
  • Includes an optional funnel so inserting coins is easier

These features make this sorter much better than the original. This coin sorter sorts American coins (dimes, pennies, nickels, and quarters), but can be easily adjusted to sort coins of different sizes. Also, I've made the instructions so that the coin funnel is optional, just in case you don't have enough pieces. The funnel just makes it easier to add the coins into the sorter. I first built this new sorting system in my skeeball machine. If you use this coin sorter anywhere else, please be sure to give me credit. 

This won in the Rods and Connectors Contest, thanks for everyone's support! :-)

Here's the video of Coin Sorter V2 in action:



So, if you want to build it, let's sort to the next step!

Could you please make instructions for British pennies please :) There are a few oddly shaped coins (hexagonal & an octagonal one coming soon) that may muck it up. I would make one myself but I am not the best at the mechanics. Thanks.

I'm not sure if a non-round coin would even work, since it would have trouble sliding down the tray.

Hi, shadowman! I thought this looked really awesome, so i was wondering if this worked with canadian coins?
Shadowman39 (author)  GNShmurdeshmur5 months ago

I've never tried to use those coins myself, but it should be possible since the sorting tray is adjustable. More info about this is in step 5.

How should i go about modifying it for British coins?
Shadowman39 (author)  skletz5 months ago

You'll have to adjust the connectors that make up the sorting tray, and use trial and error until the slots are the right sizes. A more detailed explanation is in step 5.

it works ok. I had to add some extensions on one side to actually get the coins to roll but other then that it's fine
Shadowman39 (author)  Bigg_Z2611 months ago

Looks nice, thanks for building!

Hi shadowman39,

I was wondering if you knew what this part is. I think it's a motor. Here's a picture. I tried putting batteries in it but it didn't work. Any tips?

That's a light module, clear tubes go into the sides and light up. It came to one of the amusement park sets.

hi ive just made this first time ive built anything with knex since my niece was little so about 10 yrs ago great instructable i extended it to work with 5 uk coins .im now 50 and unable to work so missus said get a hobby think ive found it

Shadowman39 (author)  ScottyT11 year ago

Ha, glad to see you've gotten back into Knex! It's also cool that you extended it, do you have a picture?

hi shadowman 39 thanks for the reply i got a long way to go looking at youre instructables which by the way was wrote and photographed to make it easy to understand i have a couple of pics the one with the boxes was my first one then i decided to make it with the coin holders
Shadowman39 (author)  ScottyT11 year ago

That looks nice! And I'm glad the instructions were easy to follow. I've added a picture of yours to the last step.

Hey Shodowman39 any chance you can make the coin sorter for the Canadian money?

Shadowman39 (author)  badinbadin1 year ago

I've heard that there are Canadian coins that are the same size, so I'm not sure. If you choose to sort only coins of different sizes then yes, it is possible.

No they are not I have had to adjust the coin sorter a little bit for the coins. In Canada we have two more coins a one dollar coin and two dollar coin so if you could just make it so that those can go in the coin sorter it would be very much appreciated.

Shadowman39 (author)  badinbadin1 year ago

Sorry, I'm not into building Knex right now, but it would be easy to extend the sorting tray so those other coins could be included.

Okay thanks. But why aren't you in to k'nex anymore?

Shadowman39 (author)  badinbadin1 year ago

I just lost interest, I guess it was because of moving to college.

What about your ball machine Citadel?

Shadowman39 (author)  knex akbar1 year ago

That's still standing, I've been wondering whether I should keep it or tear it down. Thing is, I was excited that Citadel was going to be a unique ball machine since it would have mostly new elements in it, but now someone else is planning on building a ball machine like that. So maybe there isn't any point in continuing it.

Will you try to build it

Will you try to build it

R.i.p shadowman39, he was a great builder, who lost interest

Quick question I had to post a comment to use images. We recently bought a motor from ebay (arrived yesterday). I tried to install it on this years ball machine (to save batteries). It didn't work so I tried another configuration, it still didn't work. Then I thought that it might be a problem with the worm gear on the motor. I took a look and noticed a chink out of the gear. Picture is below:

Is it supposed to have that chink?

Shadowman39 (author)  www1391 year ago

I'm not sure if it's supposed to have the chink because all my motors are hidden away, but I doubt that's the problem because the other white gear doesn't touch the bottom of the worm gear. When you turn it on do you hear grinding? Does the motor run fine when it isn't hooked up to anything?

What do mean by 'grinding'? It seems to work fine. Although it doesn't seem to be able to handle as much torque as yours and other knexers. Earlier this morning my brother was able to link it up with the chain lift! We had to slow it down with gears because it wasn't able to compensate for the torque. Other knexers motors seem to be able to go faster and to handle more torque. If it would help you I could take a short video of the motor in action and upload it to show you its performance.

Thank you for your help!
Shadowman39 (author)  www1391 year ago

If the chip in the worm gear is causing the problem, I think you would hear a grinding sound. I think the problem must be that the motor is either old and worn out or there is something with your power supply that's making it slower. I'm not really good with testing those motors, as I only have 3 and all have been new when bought. You could post a video if you want, though I don't think I can help any further.

The motor came a day early! All is well I guess it's supposed to have that chink because the other one had it. Thank you for your help! :D

We have another motor coming on Friday and we can compare the motors. Thank you so much for your help. Thank you!

Sounds good, and no problem.

Hi shadowman39 I made a social network that I would like to share with you. Keep in mind it doesn't work on atat connections. Right now I'm on a cell phone but when I get a chance I will give you a link along with the master password. Hope you like it!
Shadowman39 (author)  www1391 year ago

If by atat you mean At&t, I won't be able to connect.

Will it work with Australian coins as there a bit bigger...? Thanks.
Shadowman39 (author)  AusKnex_1 year ago

It will work if you adjust it differently.

Here is my version of it! I was on mobile version so I couldn't use the I Mad It comment... Also I made it with bins and they fall in perfectly so I didn't add those things in the front!!!!!
