TRANSMITTER CIRCUIT
RECEIVER CIRCUIT
CABLE TRACER
Why pay $100 for a cable tracer when you can build one for less than $10.00! This type of tracer is used by telephone technicians, electricians and anyone laying, replacing or wiring anything, using long cables, such as intercoms, television or security.
Our cable tracer consists of two units. One unit has a multivibrator with an output of 4v p-p at approx 5 kHz. This is called the transmitter. The other unit is a very sensitive amplifier with capacitive input for detecting the tone from the transmitter and a magnetic pickup for detecting magnetic lines of force from power cables carrying 240v. This is called the receiver. The circuit also has an inductive loop, made up of a length of wire, to pick up stray signals from power cables, so if one detector does not detect the signal, the other will. Our circuit is nothing like that in the professional unit shown above.
يليت يا جماعة لو اى حد يعرف يساعدنى فى كيفية عمل هذه الدائرة بالتفصيل |
على حسب ما فهمت أن هذه الدارة لتتبع الاشارات ونقلها ؟؟؟؟
هل تتكرم وتشرح ما هي الغاية من هذه الدارة .؟
أما بالنسبة لتنفيذها فهي بسيطة وأجزاءها سهلة .
وللنقاش بقية انشاء الله
