project suggestion of electrical

sir plz suggest a project of electrical for me which is low cost' well efficient and use in daily life

You can build a wireless charger with trasnformers and diodes, I think this good and cheap project

The only limits on possible projects are your budget and your level of expertise.

Here are a few sites with a great variety of electronics projects

What your market needs will be your project trends.

Anything on Renewable/Non-Conventional energy is way good...has a lot of real life applications
