Equipment required is:
1. One fruit 1MHz crystal oscillator
2. An Audio Transformer 1000 Ohm to 8 Ohm (if there is no use IT transformer 191)
3. One fruit of ordinary perforated perforated PCB
4. One audio jack fruit (Phone Plug)
5. One fruit of the place / sheath 9 V battery
6. One 9 V battery
7. Cable Claws crocodiles (one side only)
8. Cable / anything that could be the antenna / antenna is also not what what ^ ^
9. A little solder soldering skills
Part Review:
Oscillator
Components called this oscillator is the main component of the tool that we will create. When his two feet to connect with the source voltage then on the other foot it would terbangkit voltage from 0 volts to 5Volt then to 0 volts again and so on in accordance with the frequency indicated on the body oscillators, in our tool written 1.000Mhz (1 mega hertz) there will be rising and falling voltage as much as 1 million times for second, In the world of telecommunications signals is called the Signal Carrier.
Oscillator itself has a shape like an iron box that the three corners No Runcing and pointed at one another angle. Sharp angle indicates the position of the leg oscillators unused. (Created like it to be easy to hold it at the time of going to soldering).
Audio Transformer 1000 Ohm to 8 Ohm
Components of this one is not as important as oscillators, when the oscillator carrier signal plays a role in producing the audio transformer also serves as a modulator by adjusting the amplitude of the signal information and menumpangkannya the carrier signal.
Schemes range AM radio transmitter (Transmitter Radio AM)
Here is a picture series that is so:
How to make this AM radio transmitter:
1. If the transformer you buy right then on one side will protrude 3 wire copper and on the other side will only have 2 copper wire. Side with 3 wires protrude is the side that has a high resistance of 1000 ohms while the side with 2 wires sticking is the low side berhambatan 8 Ohm.
If in Indonesia there are no wires leading from the transformer, which in isolating with colorful insulators such as the above items. But to more easily explain how to manufacture, position your transformer as in the picture and consider the top left corner of the copper cables are wired as shown in green, as well as the copper wires on the lower left corner we consider the blue wire as shown. (Position 3 cable is facing to the left and 2 cable facing right)
2. Attach an audio transformer on your PCB (Glue or whatever it's up) with high resistance side facing out (see picture). Last solderlah green and blue cable on the audio jack as shown below: (do not forget to close again when it is soldered onto the audio jack)
4. Connect the negative battery with leg oscillator bottom right corner and at the meeting point is also connected with a cable that had crocodile claw on one end of it. (Green Claws cable in the picture).
5. Connect the upper right corner of the leg oscillators with crocodile Claws cable (yellow claws at the picture)
6. Terahir, Connect the antenna and claws yellow with green claws with a good grounding (Ex: Your Body). Viola! Ready to operate your tool!
How to Use ?????
Easy enough, connect the audio jack us with an output audio source such as: Nokia Express music or speakers speakers SIMBADDA. after that install the battery and try to bring us to the radio transmitter secured AM radio sound that we play will be caught by the radio.
If we want our voice Entering ?????
buy enough Mic Compressor circuit. Do not forget to buy Condensator his Mic + Battery 12V. because in a series that has become his mic did not exist, only two holes where the solder his mic. so have to buy their own.
Hopefully Helpful ...
