Make MW transmitter Using NE555   Using comments NE555 timer chip 330 ohms, 1K ohms resistance 0.001uF capacitor Condenser mic and 9V DC power supply. Power supply :-  Using supply only DC stable you can use 9Volt battery and smps supply And mobile adaptor unfortunately it is no 9Volt but approx 7V max. NE555 timer chip :- This chip number 1 pin Ground, pin 2 Trigger, pin 3 Output, Pin 4 reset, pin 5 Cout, pin 6 Three, pin 7 discharge, pin 8 VCC. Important notice this chip you cannot supply voltage 9 volt up otherwise timer cheap was burning. This chip integrated 2 op-amp or 1 SR flip-flop or one NPN transistor and voltage divider. Supply voltage minimum 4 volt up and maximum 10 volt. Capacitor :- Using capacitor 0.001uF this capacitor number 102. You can used any condenser mic MW frequency :-  Medium wave is the part of the medium frequency radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with limited sound qualit

FM transmitter signal booster circuit Diagram This signal Amplifier (booster) work only FM band. Important notice you can you big antana and antana place teddies on your home. so your signal more than area of coverage this booster more than 10 km range. You can watch the video go my youtube channel. This circuit Diagram work frequency boost up low amplitude to high amplitude. You can not use MW and SW transmitter because this design for FM circuit only. Using transistor - BC547. You can use any of MHz frequency range transistor examples (BC548, 2N222 extra you can search google). Using capacitor 1uF ceramic capacitor. You can also use 1nF, 10nF, 0.001uF. capacitor place transistor or inductor maintain distance 1CM. You cannot maintain distance than your frequency more than noise added your signal. Using resistance 220K ohms and 10K ohms. Using incuctor made than use you screwdriver throttle 10 turn 20 SWG wire. Using powe supply max volt apply 15V but I am using j

FM Transmitter using Raspbarry PI model 3 B What is respbarry pi : - The  Raspberry Pi  is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. Hardware requirement :- you can use raspberry Pi zeroW, raspberry Pi 2, raspberry Pi model 3b, raspberry Pi model 3b Plus, raspberry Pi 4. FM RDS setup :- Frist you go to GitHub and search FM RDS search results selected FM-RDS than copy clone link than go to terminal type $ sudo git clone (paste link) than prass enter file download start complete download than go to file path type $ cd PiFmRds/src press enter than type  $ make clean press enter  $ make press enter than automatic create run file. Run you pi FM transmitter type $ sudo ./pi_fm_rds press enter Run pi FM transmitter default frequency 107MH
