We’ve seen plenty of custom keyboards here on Hackaday. Seriously, like more than we can count. But custom mice? Those are far more elusive. Though we wouldn’t be surprised to see that change should this excellent example from [Tyler Richard] catch on.
The goal was to build a customizable mouse that could match the performance of Logitech’s MX Master 3, but without the $100 USD price tag. In the end, [Tyler] says his mouse is around 10x as responsive thanks to a 1,000 Hz refresh rate, and the total cost is just a fraction of the retail price of the Logitech. Though as you might expect, there’s a catch or two.
For one thing, he says getting your hands on the PixArt PMW3389 mouse sensor in single quantities can be difficult. It seems like he was able to secure a sample because he’s a student, but you’ll have to figure out your own way to con secure one from the company. There’s also no friendly GUI to configure the mouse, and indeed, you’ll need to write some code should you want to modify any of its buttons. Oh, and despite the fact that the cheapo donor mouse you need to use for parts is wireless, the replacement guts you’ll be fitting it with currently only support wired operation.
Alright, we’ll admit it’s not perfect. But it’s still a huge step in the right direction if you care about being able to spin up your own input devices. With some refinement, and perhaps somebody willing to do bulk buy of the sensors, we could see this project becoming quite popular. In the meantime, you may have to settle for a macro stool.
