Sorry, it's me again
So I have a few more questions:
(1) I've put a 78L09 in REG1 and am going to use a 12V supply. Am I correct in assuming it uses a center pin negative supply? And what rating mA would be best?
(2) I'm going to use a female power supply jack socket connector. From that, can I just simply solder a small amount of wire off it, then split off to each board separately? Or would it be better to run to one board first and then the other from there? Or is there something a lot more involved required to power both boards at once? And am I correct in thinking I can just solder the wire to the PCB as all the pictures of other peoples builds seem to have some sort of 10 pin spiked thingy fitted? If I do need a spikey thingy, what are they called as despite searching, I've been unable to find anything like it.
(3) How difficult would it be to add a power switch? Is it as simple as adding a suitable switch to either the positive or negative wire?
Again, my apologies for the less than primary school level of knowledge on my part, but sadly I'm a moron. But a moron that is slowly learning, so thank you for any help! I hope this is the last time I have to bother you
