Working as a Tech. in ISRO/Sac, Ahmedabad.I made a Home UV sanitizing machine made by me using old oven body.It took only two days to make. It has two modes manual and auto. In manual it is continuously ON and in auto mode it switches OFF after 120 seconds.
Many things like watches , purse,mobile etc which cannot be washed with water can be sanitized.
