A big benefit is that you can even use it when sitting on the sofa or the bed with the laptop (I know, bad habit), which is just impossible with a normal mouse. I also tried some vertical mice but overall I like the ergonomics of a trackball much more. But maybe it's just that I used the MX570 for longer already and it wore out a bit more.Īnyway, having had trouble with pain in my wrist and mouse-work induced fatigue in my fingers I have to say that switching to trackballs has definitely improved this a lot. The cheapest model (MX 570) is also the best IMHO, as it seems that Logitech changed the sensor and made the ball harder to move in the newer models, which for me feels way more sluggish. Currently I use the MX Ergo, MX 575 and its predecessor the MX 570 from Logitech. I have been getting back to using Trackballs again after a 20 year hiatus.
#KENSINGTON EXPERT MOUSE SENSOR ACCURACY CODE#
Often, we release some or even all of the design files and source code for our products. But I agree, it's hard to put "Open" as the first word on your website and then describe your products as: Mechanical design tools are good at working with STEP files each step of hardware->electronics->software gets increasingly more obfuscated.

This isn't quite as bad as, for example, getting only the compiled code out of a software project. For the other products like the trackballs, the author did not release the mechanical design files, only the output STEPs and STLs. FCStd or (more likely) Autodesk dwg/f3d/iam or Solidworks SLDPRT/SLDASM formats. Gerbers are to Kicad schematics and PCBs as the STEPs and STLs are to the mechanical design files in Freecad. 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. 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. All I can do is tell you that I'm sorry the files aren't available, and that I hope you can find something that will satisfy your needs. I could spend all day trying to convince you that my reasoning was good, but you'd still leave unsatisfied. > I made the decision some time ago to keep the mechanical files for the Mouse closed-source. I may revisit that decision at a later date, since I've slated some major design revisions to it, but that won't be any time soon. > I haven't released the design files for the Mouse, no. It's certainly possible, but my focus is not currently on the mouse, so there's no timeline. > CAD files are not available for the mouse. With a different position for the scroll wheel With momentum in the scroll wheel ALA logitech mice My perfect trackball would be the ploopy: And now everytime I use it, I notice within the hour that something is not right. After months of use it started giving me RSI. The position of the thumb wheel is not good for my hand. Better than any other trackball I have (and I have MANY). I never found the time to hack it myself. 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. You apply a strong movement and it spins dead within the second. I have a small hand and it doesn't fit right. The designer (Colin) probably has big hands. It comes in a kit and as you need to assemble it, you feel emotionally attached to it I have one of the original right hand Ploopy trackballs.
