This is just something I wanted to share as this project has been truly a journey for me to understand yoyo design 
“Monometal PIXEL HEART”
I have been attempting to design yoyos since early July 2023 and I have been at it non-stop, whenever I had the chance I would spend time working and perfecting my designs. This design I have made is called “PIXEL HEART” (Don’t ask how I got the name but it had to do something with One Piece) but I worked on this series of yoyos for 10 months now with slow iterations each time. Eventually, I reached out to @MarkD on Discord for advice and made many radical changes to improve the performance I am very grateful for the advice and wisdom he gave and now I have sent it to FPM for test prototyping.
These series of renders are the current iteration of PIXEL HEART and things that I would think I would like in a custom throw.
Specs are the following:
Weight - 64.6g
Width - 49mm
Diameter - 55mm
Material - 6061 Aluminium
“PIXEL HEART ES”
Lately, my newfound affinity towards 3A (and YYR throws) led me to make an inner rim bi-metal version of PIXEL HEART called PIXEL HEART ES. ES takes many inspirations from Hajime Mirua’s Autoscopy while keeping the design aspects of the original monometal design. However, when adding the thick inner wrap-around steel rims; such as making the walls thinner it meant the likely change to 7075. Another small alteration was with the added step on the rim’s exterior while the og PIXEL HEART was one curve.
Cross section of ES
Below are some renders of ES with gold and silver inner-rims (again taken inspo from the SpinGear colourway of Autoscopy)
Specs for ES
Weight - 66.7g
Width - 49mm
Diameter - 55mm
Material - 7075 + SS
Because I have not done any inertia calculations yet since I currently use a mix of AutoCAD and Rhino, I am unsure of the performance of ES. On the other hand, the width and diameter of ES are the same with the only exception of the weight being around 2 grams heavier. My current prediction is it would play a bit heavier and slower in terms of agility compared to the monometal design, however, the added weight from the steel could indicate more spin power and spin time which would work well for 3A play. Some might suggest that the width of ES is too wide for 3A play as it is recommended to have a width of around 43mm, nevertheless, there are current trends of yoyos getting wider and tricks getting harder (An example of this being YYR’s Liminal Autoscopy with a diameter of 54mm and width of 47mm) but just to remind readers that these yoyos are designed for 1A play.
To conclude my current thoughts on ES, the design is still in its early phase and more tweaking can be done to it to give it the best balance of power and agility (especially when mmoi calculations are not done yet).
I hope you enjoyed this post about my current endeavours and efforts to yoyo design and would you think you would play with one of these? Let me know your thoughts
