Do you often get irritated by sorting the coins after work every day? People usually spend quite some efforts sorting the coins before they could calculate the total amount of money. It would be so much easier if there is a coin sorter to handle this task for you, and all that is left to do is add up the total amount! Today, we are going to show you a home-made coin sorter that you can build on your own!
Home-made Coin Sorter That Sorts All Your Problems
Makers are a group of inventors who find inspiration from daily life and solve problems using technology. Now, Wen Create Maker Room would like to show you how to easily sort the coins that we use every day!
The entire structure can be divided into the following parts, “Coin Holes”, “Ramp,” “Separator,” and “Coin Chutes.” The Ramp involves a bit of inserting the coins and separating them.
The biggest difference between the coin sorter built by Wen Create Maker Room and those by others is the minimal space used. A sloped surface is used to keep the runner, the ramp, and the separator on the same surface. By doing so, there is no need to connect a separate ramp to the runner.
The first model was built based on instructions from a video, where the runner was built on a stand. It turned out that there was a height difference between the runner and the ramp due to some minuscule tolerance. The same problem still existed in the second version whose stand we had strengthened. In addition to the height difference between parts, the motor was a bit shaky when it was rotating, causing it to be stuck occasionally due to the interference between the runner and the ramp.
In the third trial, as we kept trying to strengthen the foundation of the standing column, we realized that the best way to make the two different surfaces completely parallel was to raise and lock the stand and the parts supporting it. Just as we expected, the fourth trial turned out to be quite successful.
Despite what had been achieved, the motor still shook at rotation because the runner used was too large. Therefore, we downsized the runner that could originally hold the weight of 8 coins to a smaller one that can hold 6. A celluloid sheet was used as a backboard to prevent the coins from dropping out. In this way, the entire structure was stable. As for parts that required electromechanics, we used a TT motor and a speed controller switch.
Makers make constant improvements from a couple of trials and errors in learning. With abundant resources on the Internet today, beginners can build their own works from scratch. Through open-source platforms where Makers share their experience and methods, more people can avoid the same mistakes and get a sense of fulfillment and satisfaction in their work.
