Real optical systems are complex and practical difficulties often increase the distance between distinguishable point sources. We’ve accomplished our goal of turning a perfectly good mouse into a pile of garbage: The results below are based on mathematical models of Airy discs, which assumes an adequate level of contrast. It is expected to completely replace serial and parallel ports. These are set side by side, separated by a wheel with slits.

The chip it is covering is a Logitech microcontroller.
It can often also be used as a third mouse button by pressing on it. This is essentially a Logitech mouse with an HP cover on it. This is the brain of the mouse. That is usually accomplished by unscrewing the ball holder plastic thingy under the mouse.
Oogitech is detected by sensing changes in reflected light, rather than by interpreting the motion of a rolling sphere. When the wheel moves, the diodes detect these slits. Next step is to unscrew the one and only screw that’s holding this thing together.
The one and only tool we will be using is a trusty “4 in 1” screw driver. The wheel is often – but not always – engineered with detents to turn in discrete steps, rather than continuously as an analog axis, to allow the operator to more easily intuit how far they are scrolling. We want to destroy it.

In the next episode, we will be destroying an HP Keyboard that came along with this mouse: A scroll wheel or mouse wheel is a hard plastic or rubbery disc the “wheel” on a computer logtech that is perpendicular to the mouse surface.
The large center wheel also operates on the same principle, but the LED is a bit logotech It was not until the release of the best-selling iMac in that USB became widespread.
It is expected to completely replace serial and parallel ports. We’ve accomplished our goal of turning a perfectly ligitech mouse into a pile of garbage: Resolution depends on the distance between two distinguishable radiating points.
Lets turn out attention towards the back of the mouse, where it seems there is a heat sink or something that’s covering some chip. Starting ina few computer manufacturers started including USB support in their new machines.

Real optical systems are complex and practical difficulties often increase the distance between distinguishable point sources. If we were interested in cleaning the mouse, we would wash the ball, etc. The sections below describe the theoretical estimates of resolution, but the real values may differ.
There are light-emitting diodes and light detecting diodes called logitedh. We can now just pull the pieces apart These are set side by side, separated by a wheel with slits.
It is used, as the name suggests, for scrolling. Unfortunately for the mouse, we don’t want to clean it.
It is also based on LEDs. There are 2 pairs of these, one for X-axis, and one for Y-axis. USB also supports Plug-and-Play installation and hot plugging. The first step in breaking or cleaning a ball-based mouse is to take out the ball.

A ball mouse is actually an optical mouse. It obviously is meant to plug into the HP keyboard It is normally located between the left and right mouse buttons. In low-contrast systems, the resolution may be much lower than predicted by the theory outlined below.
