Hi everyone today I'm going to give you a Vedio transmitter circuit diagram.As the transistor we have used  transistor 2N2222 And I must say this.this circuit is not a tested one this circuit was given by one of my friends you test this circuit and tell me the experience The transistors which can be used  are   BC108, BC546, BC337 or  2N2222.This circuit is operated with 6V. Note: This is a VHF Transmitter            Don't supply over 6V   

Today we are going to give you very interesting circuit diagram.Normally most of electronic lovers love to make transmitter circuit diagrams.Already FREE CIRCUIT DIAGRAMS 4U has given you many transmitters.The specialty of this circuit diagram is this is some what powerful.By using this transmitter you can send signals up to 5ooM.here we have used very famous transmitter 2N2219 .This circuit is operated by 12v power supply.Specially I would like to tell you If your country doesn't allow you to build transmitters don't try this.We have publish this with the educational purpose.If you misused this circuit FREE CIRCUIT DIAGRAMS 4U doesn't take any responsibility of that. Note: # Build this circuit on aPCB # Without connecting the antenna don't supply power for the circuit # By using some what long wire as the antenna you can send signals to long distance

At present we can see people use wireless transmission now it has become a very famous electronic device  so today Free Circuit Diagrams 4U is going to give you a wireless power transmitter circuit diagram.This circuit can be operated with 5V power supply. You can use different coils with different Gage and test what gives the maximum power.Here we have used common transistor BD139. Note:        # Build this circuit on a PCB        # Don't supply over 5V

  First of all I must say that we give this circuit with the educational purpose If you missed used this circuit we don't get the responsibility of it.Most of the viewers sent us emails asking RF circuits like this.Here we have used common transistor 2N918.To make L1 wind 2 turns of 22 AWG magnetic wire on a 5/32 steel bolt  #  This circuit Can be operated with 9V  #  Build this circuit on a PCB

Free Circuit Diagrams 4U has given you many transmitter circuit diagrams today I'm going to give you some transmitter circuit with some modifications.This circuit can send signals up to 100 M.Here we have used IC UPC 1651.This circuit can be operated with 6V.The special thing of this circuit is we can build this circuit with one IC. Note :  # Build this circuit with 6V power supply  # Build this circuit on a PCB

We all like to make transmitters.Most of guys sent emails to Free Circuit Diagrams 4U asking simple transmitter circuit diagrams .I suppose this would be the best answer for that.The special thing of this circuit is this circuit runs with one transistor.This circuit can be operated with 3V power supply.Here we have used 2N2222 transistor. you can make the coil winding 5 turns of 24AWG wire on a 1cm plastic former.You can send signals up to 5oM in open space. Note:          #Build this circuit on a PCB           # Don't supply over 3V

Most of people like to think about wireless power.Yes now it has become a reality.So here I'm going to give you a wireless power circuit diagram.In this circuit We convert Dc to Ac then we have the ability to send power from one coil to another.This circuit can be operated with 6V. For this circuit I have used 1meter Circuit  wires to send power and receive power.  By changing the lenth of the wire and the Gage you can increase the sensibility of this circuit. Note:          # Build this circuit On a P.C.B          # When you make this circuit be careful because it generates high frequency voltage          # You have to take some efforts to get the result of this circuit

I think most of you like to make transmitters today I'm going to give you a video transmitter.The special thing of this transmitter is you can operate this circuit with 9V power supply and you can send signals about 100M.I have used this circuits for my security camera system it's working well and also when we do a concert or a musical show we need to send live videos to a big screen or a projector normally video transmitters are quite expensive but you can build this circuit with less than $10 Here I used Bc 108 Transistor If you are unable to find Bc108 you can use similar Transistors like BC337, BC546 , 2N2222   Note # Build this circuit on a PCB # without connecting an antenna don't give the power to the circuit # Build this circuit in a little space

This is a powerful transmitter so first of all I would like to tell you not to use this for illeagl things.You can transmitt signals from 2km.Use a matching antenna for this. Note # Don't give power without an antenna # For L1 make 3 turns of 1mm enamelled copper wire on a 10mm diameter plastic former. On the same core make 2 turns of 1 mm enamelled copper wire close to L3 and that will be L2. # by using R9 the gain can be controlled # Inductor L3 can be a VK220J type RFC. # This circuit operates with 9V to 18V ( Dont pass 24V)

This is a FM transmitter circuit.the spacial thing of this circuit is, this circuit can be fixed in a small space.The coil is four turns of 18swg wire wound around a quarter inch former.After turning one and a half turns from the supply end tap and fix the aerial. Note # This circuit is not legal one so don't miss use this.Though you did like that we can't get the responsibility of it. # This circuit can be operated with 9V power supply.

This is a tracking transmitter.Normally we use these thing to track animals,Rc planes etc.The power of this one is about 3.7mA.This circuit can be operated by using 1.5V button cell.The operating frequency is FM 100Mhz .But if you want to use it between 108Mhz to 88Mhz you have to use Just spread the windings of the coil just a bit About 1/2 a millimeter .This is wonderful project. Have fun with this. Note #This is not long range one but you can get the maximum advantage #supply 1.5 v #Attach 12 inch antenna #Search until mmmmh mmmmmh mmmmmh mmmmmh sound comes from your radio set
