This project is for Cal Poly Humboldt for the Engineering class 205. It is to create trophies for the CSU research Competition. This is for the users of the trophies to have a larger understanding of their trophies and maintenance.\n\n== Background ==\n\nIn 1985 the California State University Research Competition was created to bring forth ideas from numerous categories across the state every year. '''April''' 2025 marks the 39th year the competition takes place with the location being Cal Poly Humboldt. To celebrate the first ever hosting of the research competition Cal Poly Humboldt became dedicated to creating unique trophies for each category with the involvement of its students from the engineering department.\n\n== Problem statement ==\n\nThe objective of this project is to design and create two functioning egg of Columbus based trophies for the Physical and Mathematical Sciences category, they are to be presented to the 39th annual CSU research competition winners in this category.\n\n=== Criteria ===\n\n-Below resides a list of our criteria weighed in order from most important to least important\n\n{| class=\"wikitable\"\n!

Instead of using a copper coil design to create magnetic field we decided that we will be using a magnet and motor for similar results and easier design. We also conducted a test on wood conditioners for the best cosmetic appearance. For the housing of the trophy the type of wood we picked to use was redwood to represent Humboldt County and because of its distinct color. <gallery widths=\"300\">\nFile:Spf2025csucomplasercuttingredwoodbox.jpg|Laser cutting machine cutting box sides for our box\nFile:Spf2025csucompRedwoodBoxHousingeoc.jpg|Red wood and prototype boxes side by side.\n</gallery>\n\n=== Video instructions ===\n\nA good way to display a process is by making a video explaining your process. See [[Template:Video]] for information on how to add and annotate videos.\n\n{{Video\n| video = https://youtu.be/wOzJP-J9YvM\n| align = center\n| title = Egg of Columbus\n| description = Spinning Columbus Egg Prototype\n| keywords = Columbus Egg, Spinning, ENGR 205\n| authors = Ibrahim Alyassiry, Derek Gomez, Aiden Higgins, Miaka LaRose\n| date = 2024-01-12\n| location = California\n| language = english\n| license = CC-BY-SA 4.0\n}}\n\n=== Bill of materials ===\n\nDescription of costs, donations, the fact that this is just proposed, etc. For a simple cost table, see [[Help:Table examples#Cost Table]] and [[Template:Bill of materials]] for two nice formats.\n\n{{Bill of materials\n| currency = USD\n| item1 = Redwood\n| item1-amount = 1\n| item1-cost = 65\n| item1-text = Get at\n| item2 = Acrylic Sheets\n| item2-amount = 2\n| item2-cost = 8\n| item3 = Egg of Columbus\n| item3-amount = 2\n| item3-cost = 50\n| item4 = Brass\n| item4-amount = 2\n| item4-cost = 8\n| item5 = 19mm Latching Pushbutton\n| item5-amount = 2\n| item5-cost = 10\n| item6 = LED strips\n| item6-amount = 1\n| item6-cost = 10\n| item7 = Battery Holder\n| item7-amount = 1\n| item7-cost = 7\n| item8 = Magnet Assortment\n| item8-amount = 1\n| item8-cost = 6\n}}\n\n== Operation ==\n\nThe operation of this trophy is designed to be intuitive and affirming for the user. the Trophy contains a push-button switch and a rotary dial switch and a choice of two objects to spin, an aluminum egg and a 'flip-over' spinning top.\n\n{{Step\n| number = 1\n| title = Locate and Press Button\n| text = Locate the Main On/Off push-button on the front of the trophy and depress it with one finger until it clicks into the ON position.\n| image = Spf2025Eggofcolumbusfrontviewfusioncadwithpushbuttonhighlight.jpg\n| caption = Trophy with button location highlighted.\n}}\n\n{{Step\n| number = 2\n| title = Locate and Adjust the Rotary Dial\n| text = Locate the rotary dial on the trophy after it has been turned on and slowly increase or decrease the speed until an ideal frequency has been achieved causing the egg to increase velocity steadily, once the egg or spinning top is moving the dial can again be increased to achieve rotation on the vertical axis of either object. The Dial should be increased until the object is rotating at the steadiest rate with the least amount of horizontal movement.\n| image = Spf2025Eggofcolumbusfrontviewfusioncadhighlightedrotarydial.jpg\n| caption = Trophy with Rotary Dial location highlighted.\n}}\n\n=== Maintenance ===\n\nMust remove and insert batteries within the machine. Batteries last around 5-10 hours in high drain situations. Overall the user should replace them once a month.\n\nThe user should also clean the device buy dusting once a week. Thanks to the acrylic shield it gets dusty less often then other trophies.\n\n=== Maintenance schedule ===\n\nThis is when to maintain what. Please keep the format the same as it populates the kiosk in CCAT.\n\n* No Work necessary\n\n;Weekly\n\n* Dust once a week\n\n;Monthly\n\n* Replace batteries\n\n== Conclusion ==\n\n=== Testing results ===\n\nDescribe the testing results.\n\nThe test Columbus egg was able to stand up on a plate on its own when held at the right distance from the spinning magnetic plate.\n\nNeodymium magnets were much more effective for producing Eddie currents compared to ceramic magnets.\n\nWhen testing different motors we learned that the RPM had to be significantly higher to create Eddie currents than the motor we used for our initial prototypes.\n\nThe laser cutter could only cut wood up to 3/8ths of an inch thick before excessive passes were needed to cut through it, our final conclusion for cutting speed was 2.6% speed with 100% power and 4 passes to cleanly cut the redwood boards.\n\n=== Discussion ===\n\nDiscuss the testing results.\n\nWhen holding a plate with a resting plastic egg with magnets inside you are able to lift an egg laying sideways at rest into an upright position. If the egg place is held too far the rotating magnetic disk will not receive enough force to lift. Likewise if the egg plate is held too closely to the rotating magnetic disk it will cause the egg to fly off the plate.\n\nNeodymium magnets were attached to a round fixture plate and spun with a brushless motor at the full speed at low voltage (1.5V) , roughly 500 rpm and the previously mentioned plate was hovered above the fixture plate. The same procedure was done with neodymium magnets. Ceramic magnets had little to no effect on the egg however the neodymium magnets allowed the washer to temporarily enter into a eddie current induced rotation.\n\nOnce we were able to test rotation with a smaller higher rpm motor we saw a significantly stronger reaction to the magnets eddie current at a higher speed.\n\nThe laser cutter we used to cut out our boxes is a CO2 laser and therefore ideally to be used for thin materials so when approaching a material like our thick redwood board we chose to test first with 3/8ths of an inch plywood to estimate settings and then dial them in as we developed prototypes.\n\n=== Lessons learned ===\n\nDiscuss lessons were learned during this project and what you would do different next time.\n\nDuring the research and experimenting of the Columbus egg, as a team we discovered that applying the concept sounds more difficult than it was. We learned that the speed of the spinning magnetic plate was not fast enough as well as the magnets need to be more strong. We also learned being able to adjust the speed allowed for a better demonstration of the eddie currents and their effects. Additionally we learned to set goals that were achievable based on our situation and capabilities and we learned to work well together as a team.\n\nIf we were to revisit this project we ideally would spend less time brainstorming and spend more time prototyping and building the final product. The more time there is to revisit issues or components the better the final project will be. The trophies were build according to plan the entire way through but some components had less reiterations and could be improved upon.\n\n=== Next steps ===\n\nDiscuss any next steps for the project as it goes on into the future.\n\nThe next step is delivering the trophies to the Mathematical and Physical Science CSU student research competitions winners in 2025, there is no further required research or testing needed.\n\n=== Troubleshooting ===\n\n{| class=\"wikitable\"\n! Problem\n! Suggestion\n|-\n| Slow or complete\nLack of rotation\n| Check that batteries are charged and the rotary switch is turned to a sufficient speed\n|-\n| Does not turn on\n| Verify batteries are charged and correctly installed, and that the power button is depressed\n|-\n| Object rotates sparadically\n| Increase or Decrease Rotational velocity with rotary switch until movement stabalizes\n|}\n\n== Team ==\n\n* Ibrahim Alyassiry\n* Derek Gomez\n* Aiden Higgins\n* Miaka LaRose\n\n== References ==\n\n<references />\n\n{{Page data\n| part-of = Engr205 Introduction to Design\n| keywords = Columbus Egg, CSU Research Competition, ENGR 205\n| authors = Ibrahim Alyassiry, Derek Gomez, Aiden Higgins, Miaka LaRose\n| organizations = Cal Poly Humboldt\n}}\n\n[[Category:Engr205 Introduction to Design]]"}
