The Ploopy A+ Trackball Is Here

Hugged.

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.

Instantly couldn't resist clicking on some unknown thing called "the Ploopy A+".

I see we've reinvented the slashdot effect.

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?

What is a kit here? A trackball? All the parts needed to assemble a trackball? A populated circuit board, where the rest needs 3D printing? A pile of electronic components that need to be soldered together and the rest needs 3D printing?

The repairable, open hardware angle is the real sell for me. Nice to see a trackball designed to be kept instead of replaced.

Can it detect rotation?

I'm really put off by the poor quality of the 3d printed body

What size is the ball?

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

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.
