I needed another corded mouse and this time around I thought of @[email protected] and @[email protected] 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:
You don’t need to pay them anything.
You can just download all the files they’ve made available and build one yourself. The electronics have full schematics so you can either make it yourself or send the schematics to a PCB company. The shell is entirely 3d printed. All extra hardware is readily available.
If that sounds like a lot of work, maybe it’s worth paying the person who created it and is offering to do all that work for you.
