Just two little questions I could do with answering, if you have the time.
First, are there any matrix/stripboards that can take 3A? Or I'm I just going to have make my own PCB?
And second, is there a way to slow down a 12v 2A water pump? In a way that it can be adjusted if I need to later. I've looked at pwn, but I don't think it will work as I'm controlling them through a relay, via a transistor. I've also looked into a potentiometer, but one rated to 24W is rather expensive.
Cheers in advance,
