Chapter 4 features an RJ-45 Ethernet network cable tester. This project is a real
time saver and prevents headaches. Wiring 10Base-T Ethernet networks can be a
long and frustrating task, fraught with problems. The RJ-45 cable tester uses
STAMP 2 to test all eight wires in an Ethernet cable using a “walking LED” pattern.
The tester is a two-piece unit. One end is placed at the originating end of the
cable and the second part of the tester is placed at the end user PC and will test
opens and shorts.
Chapter 5 presents an infrared communicator utilizing the STAMP 2. This IrDA
transceiver allows the STAMP 2 to communicate with other IrDA-enabled computers,
laptops, and personal digital assistants (PDAs), for data collection and transfer.
Chapter 6 illustrates a multichannel wireless alarm system. The wireless alarm
system is a two-part system that combines a 12-channel alarm system with a
transmitter and a complementary receiver and liquid crystal display (LCD) unit.
With this alarm system you can monitor sensors, doors, windows, floor mats, etc.
The resultant alarm warning is sent via radio to a remote receiver and display. The
LCD unit beeps and indicates the particular alarm sensor that was activated.
Chapter 7 describes the construction of a unique and inexpensive way to measure
lightning activity up to 50 or more miles away. This monitor provides real-time data
on lightning activity by counting the number of lightning strikes in the area. This
lightning detector project is a two-piece system: a remote outdoor sensor and an
indoor microprocessor and display unit. This system was designed to provide
advanced warning for weather hobbyists or amateur radio operators who want
advance notice of an approaching electrical storm. The lightning detector/display is
based on the BASIC STAMP 2, which is used to display the number of lightning
strikes per minute via a row of eight colored LEDs.
Chapter 8 illustrates a 12-channel remote control system using an IBM
PS/2–type keyboard, interfaced to an Abacom model AM-RT4/RT5 series wireless
transmitter. An Abacom receiver coupled to a BASIC STAMP 2 controller
provides a means to control 12 different devices via radio. This system can be
expanded to control many more devices if desired.
Chapter 9 interfaces the STAMP 2 to the Motorola MC145447 caller-ID
demodulator, to provide a very useful and low-cost caller-ID project. The STAMP
2 program reads in the caller-ID data, stores it in electrically erasable and programmable
read-only memory (EEPROM), and outputs the information on the
serial LCD backpack. The program also allows selection of up to 10 telephone
numbers, which are called “blocked numbers.” If a blocked number calls, the
program can choose to inhibit that call from reaching the telephone, answering
machine, or other device.
Chapter 10 presents both a touch-tone encoder and a touch-tone decoder based
on the new CM-8880 touch-tone encoder/decoder chip. The touch-tone decoder
project features an LCD display that will display the decoded digits, which can be
utilized in many applications including ham radio, robotics, and remote control
projects. The touch-tone decoder with display can be used to monitor touch-tone
sequences over radio or the telephone line for monitoring purposes.
Chapter 11 depicts a touch-tone controller, which can be utilized in many applications
including ham radio, robotics, or remote control projects. The touch-tone
