"Wait, what? And you are writing a post about that?"
Ok ok, not very spectacular. I agree. But I replaced the broken red LED with a blue one!
Still not excited? Ok, you may leave.
For the rest of you, here is a picture.
For those that are interested: the scroll wheel works with an infrared emitter and receiver. The infrared light is blocked and unblocked for every scroll "click". I did not know this, so I thought I'd share it with you. To be honest, I never really gave it any thought..
For people that like salvaging parts, here is a list of parts you can probably salvage from a broken optical mouse:
- Several pushbuttons
- A tiny camera with crappy resolution
- Infrared receiver and emitter
- An LED.. :)
- USB cable [with one half missing]
- Some chips, but I'm not sure if they will be helpful, or if you will be able to find datasheets
Mind you, it's a broken mouse. So some parts may not work :D
