DIY or buy? Arduino needs 9v, relay 5v and fan 9 12v (and I'm struggling to determine the current each of these units need). So I was thinking either get some power supply like this: 60W Dual output 5V 12V Switching power supply which seems to be a bit of an overkill or get a decent 9v 2 3a wall wart and use L7805 with capacitors to power the relay.
