We usually use a small step-down transformer (9-0-9 VAC, 600 mA) for the power supply of our circuits. These are very cheap and they provide good isolation and safety. I do not suggest making our circuit without a step-down transformer. But if you still want to make one without a transformer then I suggest you google it.
Hello! How i can make it without transformer?
