# What if I stored data in my mouse

> It started with a dumb idea.

> I have a Logitech MX Vertical, which travels between my home machine, work laptop and other devices constantly. At some point I looked at it and thought: this thing has a flash memory. It has to, otherwise how does it remember the DPI setting between plugs. So what if I stored something in it?

[Tim Wehrle](https://www.timwehrle.de/) hat geguckt, was sich auf seiner Logitech-Maus speichern lässt. Stellt sich heraus nicht viel, aber immerhin 2 Byte, also etwa `hi`. Aber darum geht es ja nicht. Funktioniert für alle Logitech-Mäuse mit einem Unifying-Receiver. [Hier der Code](https://github.com/timwehrle/mouse-fs). `bye!`
