Hi! I thought of using a power supply by deconstructing a Switched mode power supply adapter for a project I'm doing without using a transformer power supply. Is it possible to do this? How do I calculate the current required by the system? My project consist of a PIC, 4 relays, DS1307 IC, LCD, PIR sensor and a TC35 GSM modem. Is 12V 1A power supply going to be sufficient for this?
