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:
Might not be too difficult to achieve by connecting a small electric motor to the scroll wheel axle. Then you could vary the resistance by changing a pot hooked the motor’s terminals.
