you’re free to also check out previous articles touching on other computer components.
You might have a desktop PC at work or home.
But how well do you know the components that make up a PC?
In other words, it’s the natural springiness of the plastic that provides the mechanism for the buttons.
Well that’s enough of the outside let’s hack it open!
Not surprisingly, it’s mostly empty.
Likewise, the rate of change itself can be used to indicate how quickly the scroll is.
A red LED is used because they’re cheap and most optical sensors are highly responsive to this color.
Here’s the well-regardedLogitech MX Masterwhich we’ll rip open and find out!
But when you open it up, you could more readily see what the extra dollars are paying for.
Another important chip is the optical sensor.
Logitech use the marketing termDarkfield laserto describe it, but what does this actually mean?
Rather than using standard red LEDs, two different colored laser LEDs are used.
Two lasers are used to illuminate these, so that they stand out better.
Even the two wheels are more complex the side one useselectromagnetic inductionto generate the rotation signal.
Measure this and you have your wheel output.
The top wheel has plastic spokes that break a light beam from an LED, as they spin around.
It’s akin to releasing the emergency brake on a car, to allow it roll away.
than the cheap model we looked at first.
The complexity and engineering ingenuity of the likes of Logitech MX Master was staggering, in comparison.
