CALLER ID/BLOCKER PROJECT
CONTENTS AT A GLANCE Basic Components Operation Caller ID/Blocker Parts List
nwanted calls are highly interruptive and very annoying; why not screen your incoming calls Everyone knows those pesky unsolicited callers always phone you when you re indisposed or just sitting down for dinner. Screen your calls from unwanted phone callers, bill collectors, your ex-wife/husband. The Caller ID/blocker project will allow you to identify up to 10 incoming telephone calls and display the phone numbers on a liquid crystal display (LCD). The Caller ID unit will also allow you to block incoming calls, if desired. The Caller ID project is shown in Fig. 9-1.

122 CALLER ID/BLOCKER PROJECT
Basic Components
The Caller ID project centers around the BASIC STAMP 2 microprocessor, a Motorola MC145447 Caller ID chip, and a handful of external components, as shown in Fig. 9-2. The Caller ID connects across your phone line with the ring and tip connections. A metal oxide varistor (MOV) is placed across the phone line to limit damaging high-voltage spikes. Capacitors C2 and C4 couple the phone line to the input of the Caller ID chip. The ring and tip phone line wires are fed to the Caller ID chip s input op-amp and then on to a bandpass filter, followed by a demodulator, and finally to the valid data detector, shown in the block diagram of Fig. 9-3. The output of the valid data detector is the actual Caller ID data information. Two additional capacitors, C1 and C2, are placed across the line ahead of a diode bridge, which is used to rectify the ringing voltage. This ringing detect signal is then input to the ring detect pins on the Motorola MC145447 Caller ID chip, pins 3 and 4. The ring detect network is formed by resistors R3, R4, R5, and R6, along with C5. The ubiquitous 3.579-MHz color burst crystal forms the basic reference oscillator. The output at pin 7 of the Caller ID chip drives an npn transistor, which in turn drives the data indicator LED at DS1. The Caller ID data is next coupled to P19 on the BASIC STAMP 2. The ring detect output of the Caller ID chip is fed to P18 of the STAMP 2. The ring detect signal determines that the circuit should pick up, or initiate. Once the ring signal is detected, the STAMP 2 pulls in the relay at K1. Indicator DS5 indicates that the relay has pulled in. The indicator at DS4 is a monitor LED; it stays on
