You could make a Fiber optic communication system that could be used for transmitting video, voice and data between the rooms of your house. Or a wireless Home control system that includes smart control of lighting, HVAC, security, etc.
Best of Luck with your Project works, if it works well you could consider commercializing it. Such projects are rare to the Indian market, but with the abundance of highly paid tech workers and improvementin the quality oof housing there would be a widerand wider marketfor them.
