> Optical computer mice work by detecting movement with a photoelectric cell (or sensor) and a light. The light is emitted downward, striking a desk or mousepad, and then reflecting to the sensor. The sensor has a lens to help direct the reflected light, enabling the mouse to convert precise physical movement into an input for the computer’s on-screen cursor. The way the reflected changes in response to movement is translated into cursor movement values.
I can't tell if this grammatical error is a result of nonchalant editing and a lack of proofreading or a person touching-up LLM content.
> It’s a clever solution for a fundamental computer problem: how to control the cursor. For most computer users, that’s fine, and they can happily use their mouse and go about their day. But when Dycus came across a PCB from an old optical mouse, which they had saved because they knew it was possible to read images from an optical mouse sensor, the itch to build a mouse-based camera was too much to ignore.
Ah, it's an LLM. Dogshit grifter article. Honestly, the HN link should be changed to the reddit post.
