General Scroll Saw Talk / Re: Diode Lighting Of Scroll Saw Creations.

G'day Jim,
I'm not too bright when it comes to power that drives these diode lights as I don't fully understand the power systems. I know that the power we have in our home is 240 volt DC and I think these diodes run on what is call 12 volt AC like a cars power system.
How where I live out in the bush the wife and I have two pumps setup that pump water from our outside water tank into the house. These pumps are generally used as bilge pumps in caravans and boats. To run these pumps on 12 AC we had to buy a 15amp 13.8VDC Regulated Power Supply - I understand that this thing reduces the power from our 240 volt down to 12 volt so we can run these pumps.
Now these scroll saw creations I have been looking at must be using small diodes to light them up and I don't think that one would need to go out and buy a big Regulated Power Supply. I was thinking that I have some 12 volt battery powered radios in the house and in order to run them they come with a little box thing that plugs into the wall and then into the radio so it will work. So to my way of thinking these scroll saw creations have to be lit up with diodes and possibly have a little box affair like my 12 volt radio.
I could have me DC and AC all mixed up - but I'm just fascinated by these creations and how its all done. Like I say I got no idea about power other than what I've tried to explain above.
