       | had a better feel than the current model. I kept two running for
       | years but they finally gave up the ghost.

       | In theory a trackball is nice (I've used one for years). Your
       | wrist can rest while your fingers do the moving, and it keeps
       | rotational momentum after you lift your fingers, making long
       | movements easier. However, your fingers will always be a little
       | sweaty and the ball will deposit that on the wheels inside the
       | device that transmit the movements. Keeping those clean over time
       | can be quite a chore, but if you don't clean them the
       | transmission will become unreliable.
       | 
       | If a trackball could be magnetically suspended so it floats
       | without touching anything and still transmit its movements, that
       | would be perfect. You'd only have to clean the ball itself once
       | in a while, and that would be easy enough.

         | My Logitech MX ergo doesn't need a lot of cleaning. Once in a
         | while maybe. But it is designed in a way that the dirt comes
         | out at the bottom by itself. There are also no wheels, it uses
         | optical detection of movement, like an optical mouse.
         | 
         | Once in a while a hair or some dust gets stuck in front oft the
         | sensor. Then you need to clean it. But this happens maybe twice
         | a year for me.

       | Some drawbacks I can think of are the mouse wheel placement and

         | 
         | Due to the new QMK firmware, the Ploopy cannot be used
         | simultaneously with some very expensive KVMs and KMs. That's
         | because they are all built on the assumption that they are
         | connected to _one_ keyboard and _one_ mouse.
         | 
         | I have tons of great QMK keyboards and I can't use them with

           | I understand your particular pain, but I want to share the

           | because it's very rare that any of the custom firmware
           | configuration tools for input devices get ported to macOS.
           | But QMK has a port and if a device wants to present itself as
           | just a bog-standard USB device with all the "translation"
           | happening on the device rather than requiring custom drivers
           | and additional software on the OS side, everything just
           | works. I presume users of other non-Windows OSes have similar
           | takes, and I really hope the QMK trend gets picked up by
           | Logitech, Kensington, and MS's hardware team eventually so
           | that more hardware on the mass-market/affordable end of the
           | spectrum can also do these things.

         | all the tooling to them. Alas, I can't find an archive of the
         | page that was up announcing the whole thing in detail. Really
         | great product. Anyway I can't vouch 100% for the new
         | Trackballs, but I wouldn't think twice about buying another one
         | if e broke.
         | 
         | Two big advantages with the L-Trac, first it has very different
         | ergonomics from a mouse, unlike most other trackballs on the
         | market. (I still use mice for gaming, but too much mousing will
         | give me an RSI in my wrist.) The CST trackballs really promote
         | a fully open hand posture, and for me at least the pinching
         | with my thumb is what gives me problems with mice. The other is
         | the roller bearing that make the ball much smoother to operate
         | than anything I've compared it against.

         | The Open Source Hardware Association describes OSHW as
         | "hardware whose design is made publicly available so that
         | anyone can study, modify, distribute, make, and sell the design
         | or hardware based on that design. The hardware's source, the
         | design from which it is made, is available in the preferred
         | format for making modifications to it." Kicad/Altium would
         | certainly be appropriate for the electronics.
         | 
         | Gerbers are to Kicad schematics and PCBs as the STEPs and STLs
         | are to the mechanical design files in Freecad .FCStd or (more
         | likely) Autodesk dwg/f3d/iam or Solidworks SLDPRT/SLDASM
         | formats. For the other products like the trackballs, the author
         | did not release the mechanical design files, only the output
         | STEPs and STLs. This isn't quite as bad as, for example,
         | getting only the compiled code out of a software project.
         | Mechanical design tools are good at working with STEP files;
         | each step of hardware->electronics->software gets increasingly
         | more obfuscated. But I agree, it's hard to put "Open" as the

       | I have one of the original right hand Ploopy trackballs.
       | 
       | - It comes in a kit and as you need to assemble it, you feel

       | 
       | - The designer (Colin) probably has big hands. I have a small
       | hand and it doesn't fit right.
       | 
       | - The 3d printed texture is great.
       | 
       | - The ball doesn't 'flow'. It doesn't keep momentum. You apply a
       | strong movement and it spins dead within the second.
       | 
       | - I absolutely love it is open source, but there is not much of a
       | community around it, probably because the barriers of entry are
       | quite high. I never found the time to hack it myself.
       | 
       | - It tracks the movement extremely well. Accuracy, precision are
       | awesome. Better than any other trackball I have (and I have
       | MANY). On par with the logitech mx master.
       | 
       | - The position of the thumb wheel is not good for my hand. After
       | months of use it started giving me RSI. And now everytime I use
       | it, I notice within the hour that something is not right.
       | 
       | My perfect trackball would be the ploopy:
       | 
       | - With a smaller body for small hands
       | 
       | - With momentum in the scroll wheel ALA logitech mice
       | 
       | - With a different position for the scroll wheel

         | For this issue, some people have modified their Ploopy

           | Personally, I prefer trackballs (specifically the "thumb"
           | type) because they minimize wrist movement and finger
           | contortions. Using a trackpad or mouse for an extended period
           | of time, my wrist gets quite painful, and clicking on a
           | trackpad likewise makes my finger joints painful. This is
           | probably not fundamental, but trackballs just seem to make
           | ergonomics easier.
           | 
           | Secondarily, with a trackball it's easier to cover a large
           | area "ballistically" i.e. with a mouse or trackpad you might
           | have to do multiple side-to-side traversals in order to go
