I needed another corded mouse and this time around I thought of @PKL@mastodon.social and @pronk@mastodon.social instead of Logitech's shareholders. These guys make open source mice among other open source hardware under the brand Ploopy. You can order one from them, assembled or as a kit, or you could print and build it entirely by yourself.
The mouse itself is pretty great. Coming from a long line of Logitech (MX518/G5/G500/G502), it's a bit larger than what I'm used to but I think I'm getting accustomed to it.
Here's another shot of it:
I bought a Ploopy Thumb a few years ago. I assembled it myself, and was pleasantly surprised at how easy it was (when actually following the instructions).
The small button on the right has broken twice, which wasn't a problem because I just downloaded the stl file and reprinted the button assembly.
I wanted horizontal scrolling, so I used QMK to make the trackball a scroll wheel when the right side button is pressed (that may explain the faster button wear). It was surprisingly easy, and there was even a comment in the source code pointing out which line I should modify for horizontal scrolling support. I guess they expected people to want this feature.
The price is high, but I don't expect to buy another mouse unless my needs change. The open source hardware and software is excellent, making repairability 10/10. The edges of the buttons are slightly rough, but I have the 3d printing files, so I get to choose what material it's made of and what post processing / smoothing is used. It hasn't bothered me enough to do anything about it.
While I can't recommend a trackball mouse to anyone, I can recommend Ploopy. It's one of the few products that I feel like I actually own.
How do you use a trackball mouse? Does moving the mouse and moving the trackball both move the pointer? Or one moves the pointer and the other does something else?
I helped a user who exclusively uses a trackball and started getting used to it within seconds. My thumb was definitely not used to the trackball but I very quickly adapted and could navigate the computer normally
The mouse stays in one location with grippy feet and the trackball moves the cursor. There is no sensor for mouse movement. It does take a while to get used to.
The reason I chose it was that I didn't have enough desk space to move a mouse. I barely even had enough space to put the mouse. Now that I've moved house, I just like the novelty. It's not as accurate as a regular mouse.
I would love a mouse that could do both regular movement and trackball movement so I could have 4 axis inputs. Sadly, I haven't found any like that.
This is not true of all trackballs. Some can be more accurate than a mouse with the push of a button.
That may be technically true, but what's stopping someone from using the same button on a regular mouse?
A regular mouse can have a large amount of movement with your elbow and very fine control with your wrist. Your thumb on a trackball may have more range or precision than either, but not both combined.
My personal experience is that a trackball mouse is a little less accurate when trying to move a large distance precisely. Perhaps I just need more practice.
Do you have a button in your regular mouse that enables precision mode?
I don't personally have a regular mouse, but most "gamer" mice have a DPI button.
I have seen several pro gamers use the DPI button on their mouse to rapidly change their precision while playing. I suspect it would take more practice than I'm willing to put in, but they seem to use it to great effect.
Ok.
How'd you make the surface this smooth?
Overuse and poor lighting.
I know some people have used an acetone vapor bath with ABS prints. I've never looked into what works with PLA.
Just to save the heartache, acetone vapor does not work with pla.
LOL, makes sense. I'm considering using epoxy. Seems like there's a product that can be brushed on. It fills the gaps. Can be painted if desired.
I'd be interested to see how well it works.
I'll try to remember to post if I end up doing it.
What I really want is this, but with a trackpad instead of a trackball.
They do have a trackpad, but not in this shape.
I was surprised when I started using the Steamdeck. The Steamdeck's trackpad felt almost identical to my trackball mouse, and it took effectively no time to get used to it.
The advantage of a trackball over a trackpad is that you can spin the ball for high movement speed, then stop it after a set time for fairly accurate distance. A trackball (or trackpad) will never be as accurate as a regular moue, but it is surprisingly usable (after a few months or practice).
I've used several trackballs, but they have all been seriously uncomfortable for me and my specific brand of RSI. My current "mouse" is a Steam Controller, but using it one-handed isn't great due to the uneven weight distribution. I also have much better accuracy using a trackpad vs a trackball.
Ideally, I just want a Steam Controller cut in half with a more confortable grip that doesn't dig into my palm.
