Hi every one today I'm going to give you 230 V light sensitive circuit diagram.When it is getting dark light switches on automatically.If you are under 18 years old Don't try this circuit diagram .To get positive results build this circuit on a PCB.<div>

Hi all today I'm going to give you a <a href="http://freecircuitdiagrams4u.blogspot.com/" target="_blank">Tv transmitter circuit diagram</a>..Actually Tv transmitters are ban in some countries. So If build this build it with your own risk.Here we have used transistor BC 108.This circuit can be operated with 12V power supply.With out supplying an antenna don't supply power for the circuit.With this circuit diagram you can send signals up to 75 m to 100 m.Try this circuit and have a nice day.<br />

Here I'm going to give you a <a href="http://freecircuitdiagrams4u.blogspot.com/" target="_blank">circuit diagram</a> which is sensitive to sound.According to the sound this will blink its LEDs..Here we have used Tip31 transistor to light up the leds.But that power is not enough so I have used Lm386 Ic to boost the power of music.This whole circuit can be operated with 12v power.<br />

Hi every one May you have a good day.Most of members asked about 120V LED Lamp circuit Diagram.You all know <a href="http://freecircuitdiagrams4u.blogspot.com/" target="_blank">Free circuit Diagrams 4U</a> is a web site which is giving wide range of electronic circuit diagrams.When you build this circuit Build this circuit on a PCB.And also Don't forget to add a fuse for <a href="http://freecircuitdiagrams4u.blogspot.com/" target="_blank">this circuit diagram</a>.When you use electronic equipment always use correct watt value.<br />

Today I'm going to give you <a href="http://freecircuitdiagrams4u.blogspot.com/" target="_blank">a simple bug circuit diagram</a>.By using this circuit you can send your FM signals up to 30-50 M. Here the coil is tapped at the 6th loop.We have used common transistor 2N2222. And also this circuit can be operated with 3V power supply.When you build this circuit build this circuit in a small space.Antenna should be 1 feet to 3 feet.With <a href="http://freecircuitdiagrams4u.blogspot.com/" target="_blank">this circuit</a> you will be able to transmit FM signals between 90Mhz to 180 Mhz.<br />

Hi We all like to make music circuits .So today I'm going to give you a very useful circuit diagram.Actually <a href="http://freecircuitdiagrams4u.blogspot.com/" target="_blank">this circuit</a> operates with common Ic called UM66.And another important thing is <a href="http://freecircuitdiagrams4u.blogspot.com/" target="_blank">this circuit</a> runs with 3V power supply. By using BC 548 the power of the sound has been increased.I think you will enjoy with this circuit diagram.<br />

Hi guys today I'm going to give you 24V to 12V converter circuit diagram.Most of the heavy vehicle drivers asked me about this.Here we have used IC LM 338.With out connecting a heat sink don;t power up the circuit.We hope to give you more 24V DC circuit diagrams.And also this circuit can generate only 5A don't forget it.<div>

Hi every one most of you guys asked me about some circuit diagrams which are related to transmitters So today I'm going to give you a very simple but powerful circuit diagram.This circuit can transmit signals up to 1Km in an open space.This circuit powered with 12v power supply.Here we have used very popular transistor 2n2218.When you design this circuit diagram try to fix all the parts in a small area then you can get positive results.Without fixing an antenna don't give the power to the circuit.As an antenna fix 30cm wire.So enjoy this wonderful circuit<div>

Today I'm going to give you a very impotent circuit for vehicle owners .Because most of you asked me about 12V Led circuit diagrams .So here is the circuit diagram.This is very simple and you can use three LEDs with this circuit diagrams.We have used only one resistor with this It is 47 Ohm resistor<div>

Hi every one today i'm going to give you a very useful circuit diagram .At present we can see a lot of scientist talk about wireless power transmission.Here I'm going to give you a basic knowledge of it. Actually it is a very simple circuit diagram so that you will be able to get some idea about wireless power transmission.I have used 9 V power supply to give the power for this circuit diagram.Now I like to talk about the coils you can use 22 SWG and two turns and the diameter should be 6 cm.Either coil should have the same diameter and the turns.<span class="Readmore">

This is very useful circuit diagram because we all love to make different types of sound generators .Today I'm going to introduce you a machine gun sound generator circuit diagram.Free Circuit Diagrams 4U has already given you different types of sound generators with our previous posts.Actually this machine gun sound generator operates with 3V power supply.And also here I have used common IC UM3561.To amplify the out put signal I have used BC548 transistor.I have attached this circuit for my mountain bike and enjoy with this a lot.Hope to see you soon with another post <br />

Hi every one this is 230V LED bulb circuit diagram.At the moment 230V LED bulbs have become very popular due to its low power consumption and due to it's clear light.I suppose this little circuit will be very useful circuit for you all.If you are an underage guy don't try this because 230V is so dangerous.<br />

Hi every one today there is a special circuit for you .It is nothing but an inverter circuit diagram.If you supplied 12v you can get 230V as the out put current.IRFZ44t loads up to 200W ,or 350W into IRFZ48 IRF3205 Can load up to 600W.When you build this circuit always try to use quality parts.And If you are a kid don't try this circuit diagram because 230V is dangerous.When you check this wear rubber gloves.<br />

Hi guys today We hope to give you a very simple fade circuit diagram.First of all I must say that this is a circuit for beginners.When we switch off the circuit it will take some time to switch off the light.After switching off the circuit the LED will get the power of capacitor.When the charge of the capacitor reducing we will be able to see like fading out the LED<br />

As electronic lovers we all have to face many troubles when we check some circuits.Among them soldering matters act a major part.Sometimes we can't see those faults with our eye.Some times using multimeter is also some what difficult because we have to read the value of it but by using following circuit diagram you will be able to guess whether the connections of the circuit is ok or not..Here we have used IC 741 .This circuit is operated with 9V power.<br />

Hi every one today We are going to give you a very simple night lamp circuit diagram before this time also FREE CIRCUIT DIAGRAMS 4U has given you night lamp circuits.Here we have introduced 120V circuit diagram with little modification you can use the same circuit with 230V power.<br />
When you build this circuit always try to use correct values Because Ac is dangerous.If you are a kid don't try this circuit.<br />
