Hi everybody!
Is there a yoyo Database which shows the construction of the yoyo?
Is it possible to do a reverse engeneering
It would be fine to have cross sections including the point of inertia meassured in %…
Any ideas how a reverse ingeneering could be done ? (3D Scan?)
Nothing that I know of mainly to prevent people from just grabbing other designs. But tons of people are willing to help and answer questions.
That is one view. But any how if someone whanted to steal a design it is very simple to buy a yoyo measure it and give it back.
On the other hand it could help in the decision to buy a yoyo or not.
People mainly go off specs already, measuring doesn’t do you much good. It’s cutting it that does. Just saying I don’t see much gain from this, but if you just want to learn about yoyo design and have questions join the discords and ask plenty of amazing designers waiting to answer questions.
So hi everybody,
took a while 
but I have done some homework in the last few days and I can now start with the first design.
I have found this drawing here Peak - The Yoyo Archive and started drawing in CAD to measure the POI.
Ok, one is not a database so here comes the next. Also from a drawing which I have found here:The story of the gyrfalcon – Yoyofriends
Are there any mor known drawings which I can use anywhere? Hard to find…
Looks great! The Peak diameter is closer to 54.6 tho.
I only had the drawing and the datasheet of the peak. I think there is a newer version which is produced
But the third yoyo is a 3D scan and should be precise.
I would love for MMOI to become a standard spec in the list. From my understanding, it would tell you a lot about how the thing is going to feel in play.
While analysing the yoyos there are much things clearer now how the characteristics and how they play. I think it is a usefull thing.
Great learnings out of this project for me
Here comes the next from a scan the G2 Afterlive (thanks for @G2_Jake for permiting the publishing).
The Afterlive is my smoothest throw which I own and it is very well made
The 40,9% in the y-axis make it a little tippy and there is the need for proper play but one of my favorites!
Afterlife
Scan the AL7 version next
I would like do do so, but unfortunately I don´t have the AL7 due to limited budget (I´m married and have two kids ).
I´m working on an bimetal next which is a litte bit more complicated to analyse. I think next weekend it will be finished.
Curious, what system are you scanning with? I love this data.
I’m scanning with Revopoint Mini 2 to get the raw data than transfer the data from Revoscan to Vectorworks to Photoshop.
Very cool little unit. I work for ZEISS and sell industrial 3D scanners. Haven’t really delved into the personal space but this little unit looks pretty capable.
It would be interesting to do a correlation study.
What you were doing, took me back decades to a professor in a class I was taking.
Right before the class started one day at the very beginning of the semester, he walked past a few students that were trying to play one upmanship with each other about things that they have done. Two young guys that just seem to have accomplished so much at least consideration to themselves.
I was listening to the I did this. I did that accomplishment battle, and noticed as the professor walked by into the building he had a little smirk on his face.
As soon as the class started, the professor said I have a challenge for everyone in this classroom. He said this weekend I want you to all except my challenge. Your mission can take place on Saturday or Sunday… Your choice. The mission is as follows…
Get a good night sleep and when you get up in the morning, get ready like you normally do to head out the door. This mission is best accomplished if you were on foot. Although you can be on a bicycle or you can ride in a car.
Regardless, once you’re out to the sidewalk, I want you to start looking at everything. Obviously, anytime you leave your house and go anywhere you’re looking at stuff because if you don’t, you’ll bump into something or trip over something or get hit by somebody.
But this time it will be different. I want you to look at everything. Planes in the sky. Birds passing by. The various types of payment beneath you as you move along. The buildings you pass. The fences, the gates, the walls, telephone pools lighting structures… And the list is almost endless.
Don’t just glance at things. Give them a good stare and try to think upon much trouble. It was for those things to be produced, however, they were produced, and by whoever they were produced.
Look at cars and motorcycles and buses, etc.
Try to do that for at least two hours. Mentally absorb everything that passes before your eyes.
Now either make your way back home or possibly to a nice safe nearby park that has a bench you can sit on.
Close your eyes or just stare at a wall or a tree and replay the video in your head of everything you remember seeing.
Simultaneously, I want you to grasp the reality that almost everything you looked at, you had absolutely nothing to do with its existence. You didn’t make it. You didn’t design it. You didn’t think of it. You didn’t invent it. Many things you never even imagined until you saw them for the first time.
The Takeaway from accomplishing this mission is to face the reality that no matter what you think you’ve accomplished in your life. No matter what you think you’ve been instrumental in to help the world moving forward. No matter how impressed you may think you are with yourself.
You need to face the harsh reality that even if everybody that you know is even more impressed with you than you are with yourself, that what you’ve accomplished so far in life is probably less than 1000th of one percent of the things that have already been accomplished.
No man is a mountain. Hopefully, you can spend your lifetime being a provider to others of some Useful information. But also recognize that no matter how much you learn and how much you know, you will never be the possessor of all useful information.
Always appreciate and respect being a witness to anything you don’t know.
………. I shared the above story for a simple reason.
I think what you are trying to accomplish is Outstanding, very informative, enlightening an educational.
In how you are using the equipment and programs and your skill, set to accomplish your mission using methods that I have absolutely no experience using.
Reading how you were transferring the information is like me, crossing my eyes and trying to solve some Chinese arithmetic.
I’m certain a good number of the younger folks on this forum will or can have an easier time Wrapping your heads around your methodology.
I will definitely be following along in learning as I go. Because it’s a simple fact that if you start at zero info about NovaScan etc., you can only get a little sharper as you move down the road.
What a great idea.
I can’t lie… When Doc pulls out his professor stories, I grab a plate. Cos he cookin
@Noobs74 - Would you consider submitting these to the Yoyo Archive?
