In this Project nbsp v dc to v AC we are going to make a very simple low-power inverter nbsp We have used some components to make this project Even this project can be make with scrap components present at your own home The Inverter circuit is used to convert the DC current to AC current You can make this project without any hesitation but it is an experimental circuit it can be used for commercial use There are two types of inverters True pure sine wave inverters quasi or modified inverters Pure sine wave inverters are costly while modified

In a previous post I made one transistor FM Transmitter that is also very nice and easy to make This is just another one nbsp nbsp two transistor FM transmitters It has two stages The first stage amplifies the audio signal generating a carrier signal using an oscillating and the second stage modulates the carrier signal with the amplified audio signal The amplification is done by an amplifier whereas the modulation and carrier signal generation is done by a variable frequency oscillator circuit Frequency can be set at anywhere between the FM frequency range from MHz to MHz The power

In this project we are going to design a single transistor FM transmitter circuit that works effectively in a - km range In this circuit we have used an electret condenser microphone as an input source that gains signal in analog form You can easily make this transmitter on PCB or without PCB because it consists of very few components The coils and the antenna can be designed as a part of the PCB as an antenna if you make it on PCB If you want to increase the range of the transmitter then you must install the long high
