# Coin Sorter

Ever since I was little I have been playing with coins, flipping them rolling them and of course saving them. And I'm sure that everyone has a jar full of coins that they don't feel like sorting out into usable money, so today i'm going to show you how to make a cheap coin sorter, that is super effective and capable of many ad-dons and modifications. Some of those modifications include changing holes to accept different types of coins, increasing the rate at which you can drop in coins and changing or redirecting the chutes and coin collectors.

## Step 1: Materials/Tools

For this project your're going to need a couple of supplies.

Tools:

• Glue (preferably hot glue)
• Knife or (Lasercuter)
• Scissors
• Coins
• Ruler
• Patience

Materials:

• Cardboard
• Clear plastic sheet

## Step 2: Marking and Measuring

Before you start cutting, make sure you measure how large your coins are in length. This can change depending on your currency.

For U.S currency

• Quarter .955 inch / 24.26 mm
• Nickle .835 in / 21.21 mm
• Penny .750 in / 19.05 mm
• Dime .705 in / 17.91 mm

Once you have measured out all the coins you can proceed by cutting approximately 1 inch long holes the width of each coin. (Make sure that they go from smallest to biggest or else the small coins will fall in). Then carefully cut out the holes. This may take a couple of tries if you don't use a laser cuter as the difference between coins is minuscule. The next step is to cut out a small piece of cardboard no more than a couple coins thick and glue it to the bottom of the piece with holes in it. This will allow the coins to roll down it and then fall into their corresponding holes.

My friend (Ziven) and I designed a template that you can print out and trace, or laser cut. We are providing three types of files to you. CDR, for Corel Draw. DXF, for CAD. And PDF, for printing or pretty much anything else.

## Step 3: Completing the Ramp

Check with the coins to check that all of them fall in their corresponding holes. If they don't fall in correctly try and readjust the bottom strip that you glued on previously. If they all fall into place correctly you can continue and glue on the backside that will help keep the coins in and rolling straight. Apply a small amount of glue on the outside of the connection to avoid making bumps inside where the coins are rolling.

## Step 4: Attach the Coin Chutes

Now that both sides of the ramp are glued on cut out pieces of cardboard with rectangles at a slight angle so that they can slide over the ramp and separate the holes of which the coins will eject from. Glue these pieces on and using scissors cut them straight and lush with the ground. The chutes will help separate and order the coins into nice piles.

## Step 5: Attach Backboard and Front Shield

Now that the chutes are glued on and cut flush with the ground you can move on to gluing on the back plate. Make sure that you keep the chutes flush with the ground in order to keep the proper angle when gluing on the back plate. Before gluing it you can cut the rectangle down in order to minimize the extra cardboard, then glue it on to the side with the holes and chutes. Next cut out the plastic using the same shape with scissors then glue it starting from the small side onto all the edge of the chutes for the last part which should be the far left of the machine, just dab a small amount onto the corner and then press and hold the plastic until it dries. Now you have completed a coin sorter machine that can work.

Nice project. But I don't think you're not finished yet. Now you need to make a system to funnel a handful of change into the slot design. So more cardboard is needed. Thumbs Up!
