Hi,
Basically I've done no electronics work before at all (except for a little in school), but I have a little project which I'd love to work on.
Laptop cooling pads that I've bought (with the fans on) have been completely inadequate, so I'd like to make my own. Now, I can make the actual base no problem with a couple of bits of wood, but my main concern is the fans. I know that I can strip the end off a 12V DC transformer and as long as it has enough amps, rig up as many fans as I need to the positive/negative ends and they'll be powered, but that means... stripping the end off a DC transformer and the plugs of all the fans.
What I'd really love to do is have a little circuit with a proper socket for the transformer to plug into, and then sockets for the fans to plug into as well, and probably a switch to turn them on/off. So the whole circuit can be put together without damaging any components (say I want to use the fans later, it would be annoying if I've stripped the plugs off).
So I have a couple of main problems, I don't think one of them is actually wiring the circuit, but they are:
1) What components to buy, and where from (I'm in the UK)? I found a site called rapidonline.com which seems to sell what I might be looking for.
2) How can I mount the circuit (especially the sockets) in such a way that they actually work? I had a look at a few sockets and most of them seem to say they're for PCBs, and I have no idea how to use them.
3) What's the best way to "cover" to circuit to avoid it just being open on the bottom of the cooling pad and allowing people to touch it while it's turned on?
Many thanks,
Peter
