Are you working by yourself or in a team?

I am working by myself on this project. I will not use assets from the internet so the 3D modeling will be done from scratch. The most assistance I will have will be Mr. Renner printing my design.

What materials will you need for your project?

I will need my computer for the modeling of the design. I will then need a 3D printer to make it. Then I may also need an iPad to take pictures and record videos of it.

What is your plan to create in this project?

I plan to create a simple contraption designed to identify coins. It will have a chute the coins go down and where they stop will decide the type. There will also be a little door indicating the type.

What unique qualities will your project have?

It will have the quality of being a slightly specific tool having one use. But though the need to identify coins is only occasional when it happens it can be quite annoying if you want to double-check the type. That is where this minimalistic design will come into play.

Daily Log:

Day 1

I began work on my project beginning to model out the design. I began working with the door mechanism but had some technical difficulties. I decided that I would do a mechanism that slides in

Day 2

I finished the basic door mechanism on the design. It added two small edges within the track the door slid into to steady it. I removed this edge on the side that would have ruined the design if I had not caught it.

Day 3

I added labels to the door. I also double-checked to make sure the track design would work. I had to temporarily postpone this project though because of how long the queue was to use the printer

Day 4

On this day the project resumed after a brief intermission. I had spare time after completing 8p2 so I got back to work. The design was finally ready to be printed.

Day 5

On this day I got my project printed. I realized though that the fit on the door was slightly off from me editing it so it did not work. I learned that next time I should probably look more into the scale of the design.

Day 6

On this day I recorded the video of the identifier in action. I had issues extracting the files though so I had to redo it. It turned out that my project did not sort nickels correctly sadly.

Day 7

On this day I realized while I was transferring my video one of the files had been corrupted. I had to record it again which was quite inconvenient. Also I had to do it without a coin because I had already returned the one I used the day before.

Description:

Using TinkerCad, I created a coin identifier because I had trouble telling coins like quarters and nickels apart. I then printed this design using a 3D printer. The two pieces of the design were printed separately to prevent them from sticking together and to avoid inconvenient supports.
During this process, I learned that when I make 3D models that I plan to print I should keep my eye on the scale in all parts of the process in case I accidentally mess it up. If I had done this after fixing the edge the door likely would have fit better in the slot. But I did not so now it easily falls out.
The 7 standards of the class are Empowered Learner, Digital Citizen, Knowledge Constructor, Innovative Designer, Computational Thinker, Creative Communicator, and Global Collaborator. My project ties to Innovative Designer because at the beginning of this project, I had little clue how I would do a lot of the original goals but I kept refining it to solve it's problem better and be more convenient.. This ties to the Innovative Designer standard because they are all about working with problems that have indefinite answers and refining their designs through processes.
A challenge I overcame on this project was getting rid of this edge that would have blocked the door. I was able to do it by repositioning the hole so it would shave it off. I failed to notice though that I made the hole too wide which messed with the fit of the door.
Given a chance to do this again, I would change the fit around the door to be more snug. The reason why I would change it is because it was so loose it easily fell out. I would likely fix this by making it wider.
Hastings High School Career and Technical Education Program offers Agriculture, Business Management, Computer Programming, Construction Trades, Culinary Arts, Digital Multimedia, Engineering Design, Finance, Insurance, Marketing. My project connects to the Engineering Design CTE program at Hastings High School. It connects to this program because for my project I had to work with different ideas and designs until I found the one that was a good solution to my problem. My project connects to careers in Engineering. If I was to work in this field I would work in a very similar way to what I did in this project, in that I kept tweaking the design until it solved its problem well, but with different goals in mind.
