| Principle of this project |
Parts
• 1. BC547 transistor 3 in this number!
• 2. 10pf capacitor whose code is 10! Pf 2 of the 10 numbers!
• 3. 22n capacitor 223 the number pf 2 of the Code
• 4. 1n capacitor 102 which codes the number of pf 1
• 5. 100n capacitor 104 which has the number pf 1
• 6. The capacitor 39p whose code number pf 1 of 39
• 7. resistance 330 ohm 1, the color orange, orange, brown, gold
• 8. resistance of 470 ohm 1, the color yellow, purple, brown, gold
• 09. Resistance 47 kiloohamera 1, the color yellow, purple, orange, gold,
• 10. Resistance 150 kiloohamera 1, the color brown, green, yellow, gold
• 11. Resistance 22 kiloohamera 1, the color red, red, orange, gold,
• 12. Resistance 1 megaohama 1, the color brown, black, green, golden
• 13. Resistance 39 kiloohamera 1, the color orange, white, orange, gold,
• 14. tyanka circuit or an RF coil! It allows you to create your own! 20 or 22 gauge
copper wires twisted it with a pencil on the left for 6 to 8 can create! Motor oyendim
copper can be collected from the shop!
• 15. trimmers 47p capacitor instead of the Code 47 This number pf 1. It would
be helpful if you need to change phikuyenansi trimmers.
• 16. An electric microphone! It is able to collect from the old cassette
player!
• 17. A small red light LED.
• 18ekati small switch
• 19. Two pencil batteries!
• 20. 35 to 40 cm!
They collect the following image and Connect!

| Circuit Diagram |
1. Battery power has been used to ensure the LED.
LED switches positive = positive (which is derived from the battery). LED negatives
= battery negative.
If you think that the red LED will ruin your battery charge, then you
can skip it!
II. Microphone circuit's negative view of the negative = tinker.
When you're given a link to a song or music to play in front of Microphone or from
the device you want to transmit music to it and Audio output lines to connect the
Audio input circuitry.
Turn on the FM Radio 88 108 MHz any one position. If using the trimmers trimmers
set to turn the channel, please, if you do not use 47pf circuitry on one side
of the coil to naracara quietly with hands! Then you will see on your FM Radio which
you are going to hear the music clearly seems transmit
Or Radio tuinim OK. You will receive a new Station, which is playing your song
or music.
If you want to listen to Radio the other songs on the Radio bajateche megaharje
you select it.
You have entered the music circuit with the device will be a little less than its
sound. If it does not sound good for an extra base on karane Radio does not
sound. If your sound system is not the volume reduction system or small moves saundei
Extra Base Radio on which transmit sound can not be heard clearly, then the
quality of a variable resistance 100k lailei Sound Control, you can set the
input.
If you use 2 hands, as this tryansamitarera antenna 150 feet can be heard on Radio
durute like! If you use good quality antenna, it becomes able to transmit up to
600 feet situated! You also can use the antenna on the radio!
