This is a breakout board for our Blackberry Trackball.
The four spindles on the trackball have a tiny circular magnet the end; each of these are paired with an SMD hall effect sensor,
which are used to measure up, down, left and right movements of the trackball.
An SMD momentary switch is placed under the trackball to give you a select switch.
The BTN line will be pulled low when the switch is pressed.
Also included on the Trackballer are 4 LEDs: red, blue, green and white.
These can be powered to light the clear trackball up any color you can imagine.
All features are broken out to a 0.1" pitch header. Regulated, 2.5-5.25VDC power
must be provided to power the Hall sensors.
The trackball is attached with strong CA glue. Board comes as shown, with all components populated.
The hall-effect sensors and trackball combo are surprisingly sensitive.
A slight roll of the trackball creates multiple high/low transitions on the four axis pins,
easily picked up by any microcontroller essentially giving you the option of adding a mouse to your project.
A 360° rotation of the trackball, along a single axis, will result in about 9 high/low transitions.

Item Description
This project uses bright infrared (IR) LED and a phototransistor to detect the pulse of the finger, a red LED flashes with each pulse.
Pulse monitor works as follows: The LED is the light side of the finger, and phototransistor on the other side of the finger, phototransistor used to obtain the flux emitted, when the blood pressure pulse by the finger when the resistance of the phototransistor will be slight changed.
We chose a very high resistance resistor R1, because most of the light through the finger is absorbed,it is desirable phototransistor sensitive enough.Resistance can be selected by experiment to get the best results.
The most important is to keep the shield stray light into the phototransistor. For home lighting that is particularly important because the lights at home mostly based 50HZ or 60HZ fluctuate, so faint heartbeat will add considerable noise.
