Assalamualaikum. I m a hobbyist. I need learning material for altering/modifying electronic goods to some other useful good. E.g radio to intercom. Which may be converted back to radio by using a switch. Pl help. From Dr aamir.
Peace be to you, too. Welcome to the forum.
You need to be far more specific if you require detailed help. What sort of learning material? What is your present level of understanding/experience of electronics?
