Coin Sorter

This is a list of pictures from the book that has all of the different things that I completed for that day of the project.

Images of me actually working on the project during class at the engineering workshop. It involved utilizing hot glue, x-acto knives, and a laser cutter.

These are the images of the different systems. They are from various angles so that you can see how it would look in person. The dime slot ended up being too large to the point where the penny could also fit inside of it.

Images of the all the system put together into one final project. The supports (which are boxes created in MakerCase) had to be redesigned so that the coin starting spot would have some downward slope. They were elevated by using electrical tape and napkins to raise it a ever so slightly.

Videos of the laser cutter being utilized to cut boxes for the project and glued together late. To use the laser cutter, you must go through a long process of downloading what you want to cut, putting it through RD works, and a whole slew of other things. But in the end, it was actually much easier and more precise for things to be cut with the laser.

This is a video of the holding containers for the coins. It explains how the coins of largely different sizes have differing containers. These boxes were laser cut, and were designed using MakerCase. When one of the support boxes was being cut, I ran into the problem of the cardboard moving while the laser was cutting. Therefore, the last piece came out a bit off-centered. But the box still had strong functionality without that piece, so it was utilized anyway.

This is a video of the dime slot working correctly. The dime slot is 1/4 of all of the slots in the sorting system. The dime slot had to be redesigned because it was large enough so that the penny could also fit inside. I was able to acquire electrical tape, and this was used to make the slot slightly smaller.

When my final test was about to be run, I ran into the problem of the wires connecting the circuit together disconnecting from the rest of the circuit. I had to get a whole new motor and reconnect it to the rest of the circuit. The motor is larger and therefore now makes a much larger hum and more hopping. Since the motor was larger though, I had to increase the space in the hopper container. I did this by cutting small pieces of cardboard and stacking it to create more space. I then hot-glued them together and it successfully gave it more space.
