Stumbled upon this easy to build DIY FM transmitter. The circuit diagram and information from this post has been rewritten from the source link below to make it idiot proof. But if you've got some spare time and don't know what to do with your electronics tool-kit, you can't complain anymore. Get all your parts in one place and start building your own, small FM transmitter.



The range of this FM transmitter is about 30 ft and can be extended using a simple antenna. Please be aware that it could be illegal to do FM transmissions without valid license. You may use any regular mono-audio jack as input source (connected to your mobile), or to a microphone.

This design is based on original design posted here - #-Link-Snipped-# . It's a nice set of FAQ if you encounter any problems. Otherwise, feel free to post your doubts here and our experts can help you out. Tagging @#-Link-Snipped-# for his inputs.



PS: The last time I actually used a soldier was in 2009. Been away from electronics for a really long time but we do have a lot of talented electronics engineers to help you with your questions and doubts. If you design your own FM transmitter using this circuit diagram, please do not post photos of your project. A video would be great!
