I just uploaded a new episode of PopCast about a style of yo-yoing called Astro. Astro is a sub-style of counterweight play that uses two weights instead of one.
To go along with this video, I’ve also released a few Astro weight designs that you can download and print out on a 3D printer. These files are available on my Github with a very friendly license, you can remix them, share them, and even sell them if you like. If you end up manufacturing these, send me a set and tell me about your shop so I can help spread the word.
