The github[0] for it is kinda cool. Uses the 'CERN Open Hardware Licence Version 2 - Strongly Reciprocal'. The assembly instructions[1] give a bit of a hands on feel.
They had some more details on a reddit post[2] it looks like.
I bought the regular mouse and had a fun time assembling it. It works fine.
However the "ergonomic" design is extremely uncomfortable for me and caused hand pain. I let it ride for a few weeks hoping I'd get accustomed, the pain got better but didn't go away. Also the far-left and far-right mouse buttons are superfluous and detract from the core experience.
Please do a symmetrical version and maybe throw in a scroll wheel with steps/clicks, I'd happily buy another.
I dig that the Ploopy knob is QMK based, also high resolution. But watching how much effort E.B. has put into my favorite input device of all time, I can't help but want one of theirs.
The internal LED's are cool here. I like the indicator effect, especially with the partial transparency ball. I do wish this was bluetooh and ZMK based. Even though ZMK is lagging a decent bit behind QMK features. Zephyr is just so cool! Wireless is so great. In my opinion.
Who the hell wants to solder their own trackball? Equivalent products exist at roughly the same price point, fully assembled and tested with a warranty.
Hugged.

That's too bad.

I see we've reinvented the slashdot effect.
Can it detect rotation?
The repairable, open hardware angle is the real sell for me. Nice to see a trackball designed to be kept instead of replaced.
Don’t know what you have been using, but my Kensington Expert Mouse is over 20 years old now, and is still going strong.
They have a countdown for the pre-order here[0]. Seems like it's available as a kit Wednesday, August 19th, 2026 at 10am ET to pre-order.
I love all I/O devices..
I think the main difference from the Ploopy Adept is they added two knob buttons?

Not a trackball, but anyone else watch Engineer Bo, or tried their very nice Knob? https://youtu.be/ehd3Ue2fKKM
