Knex Coin Sorter

I didn't want to buy an expensive commercial coin sorter, so I decided to make this instead! It sorts dimes, pennies, nickels, and quarters into store-bought paper sleeves. It runs using a motor, and the sorting tray on top goes back and forth, sorting the coins according to their size.

You don't have to use paper sleeves to store the coins; you can just have them fall into piles or into something else.

EDIT: This reached 5.00*, thanks to everyone who rated! :-)

Here is a video of the coin sorter in action!



So, if you like it and want to build it, then it's onto Step 1!

Enjoy!

Step 1: Parts List

[zacharye08]

-_- I posted my reply but it didn't show up and now I have to re-post. So... pictures of all the connectors excluding green, and the Y-connector. If you can, of course. I will be very grateful for this because i first saw this almost half a year ago and I'm only just getting around to following through with it. =/
By the way...
this was my second post attempt, copied and pasted because it would not let me reply. it kept saying "please type the 2 words on the page, but it would not do anything when i tried.
Thanks

Hi, I was just wondering if you could post some pictures of the pieces in the list, I don't have all of the necessary pieces so I'm trying to buy them but I'm not sure what you mean by some of them.
Any help would be appreciated. Thanks.

[Shadowman39]

If you tell me which ones you don't know, I can give you a link so you can find out what they are.

[Blorph]

What part is the tannish-grey thing in the middle?

[Shadowman39]

It's a yellow connector.

[Blorph]

I'm building one right now!

[Shadowman39]

Cool!

[BalintRules]

does it hold english coins?

[collinjo12]

I made my coin sorter. As you can see, I used regular paper and wrote the name of the coin that goes in to each holder.
HERE'S MY PICTURE!!

[rlaxrlax]

even though i had to not use spacers and sleeves it works

[dan1900]

Hey really cool coin sorter I'm building it and was curious what is the name of the moter you used

[Shadowman39]

The motor doesn't have a name, it's just a motor manufactured by the Knex company.

[Snosageman99]

Does it sort australian coins?

[Shadowman39]

No, but you might be able to modify it to sort those.

[scottyboy8274]

I've already started making this but I had to order black hinges from Knex.

[Snosageman99]

Btw...if you get to step 10 "the coin holders" you can mod it so that it doesn't use black connectors...use grey single connectors and put the spacers ona s you go :)

[urtlesquirt]

the macince is cool, but nice cat!

[Shadowman39]

Haha, thanks!

[Snosageman99]

This step was really hard and i didn't really understand it. Can you post better pctures or tell me exactly what each piece is

[Shadowman39]

Yeah, this is the hardest part. Unfortunately I don't have better pictures, but what exactly do you need help on?

[Snosageman99]

don't worry...I finished it...but for some reason the tray doesn't tip all the way back so the coin doesn't slide anywhere. But still 5 stars

[Snosageman99]

this is epic...im gonna make it right now

[Shadowman39]

Cool!
