The Ploopy A+ Trackball Is Here(blog.ploopy.co)

Around the 2000s I remember playing a match of Unreal Tournament Classic on a LAN party again a player of a major german UT clan of the time - he was using a trackball to play and slaughtered us so hard. To this day I can't imagine precise inputs with a trackball, but I saw it is possible.

It always seems like a missed opportunity that trackballs don't detect when you twist the ball. It would be so natural for spinning a model in CAD or zooming.

The easiest approach would probably be to add a second optical sensor and do some math to calculate the twist rate.

These have been made on and off since 1995 at the latest. They never work out even though you'd think they'd be super popular for 3d modelers at least. I first encountered one for SGI workstations.

https://en.wikipedia.org/wiki/SpaceOrb_360 as one example.

Twist scroll requires two sensors and is patented by Kensington.

The Kensington SlimBlade scrolls when you rotate the trackball.

That's too bad.

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.

Looks similar to my trusty Kensington Expert, only with more buttons:

Even the wrist rest, which I've never seen on another trackball, seems to have been copied from here. Anybody tested out both?

They really need to find a better name than "Ploopy" though.

> They really need to find a better name than "Ploopy" though.

The name reminded me of Kooky Plops, the fictional band from the brilliant animated skit[1] by David Firth (of Salad Fingers fame) about the state of pop music in 2009.

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.

This paragraph is wild to me:

"The original Adept had six buttons. However, ever since we released the original Adept, the PCBs have contained two unpopulated lands for additional switches. Our intention was always to eventually move to eight buttons. The A+ finally lives up to the ambition that we set for ourselves back in 2023."

So they designed it to have 8 switches from the start - but then hid 2 of them so they'd have a "new version" once the sales of the old one slowed down. I don't know if that's genius or sad capitalism...

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?

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.

I've found my Razer Deathadder 2013 and Logitech G5 v2 very easy to repair. I go through a set of switches every 4-5 years it seems, plus cables on the G5.

Took about a year for my Kensington slimblade to start double clicking. Many others reporting the same
