Hey all, firstly - i'm new to the forum (and arduino) so be gentle with me :)
My plan is this:
I've got a Raspberry Pi, Arduino, PiNoIr Camera Module, an LGH-5036 Infra-red Illumination Board with 36 Infra-red LED's, 2 servos and plenty of time on my hands.
I have dismantled a 450w ATX PSU to use to supply power, as they have a 3.3v, 5v, 12v power rail and i need 12v to supply to the IR board.
From my reading on the web (http://forums.reprap.org/read.php?340,288817) it appears that the minimum load requirements for a 450w ATX PSU are
3.3v - 0.1a 5.0v - 0.2a 12v - 0.1a
so, am i right in assuming that to get step 1 working (safely power the IR ring), i simply need to attach an LED to the 3.3v power rail with a 220 ohm resistor, the IR ring to the 12v?
also, what the heck do i put as a bare minimum over the 5v rail?
I've been playing for a couple of days so am beginning to understand the arduino a bit more.
i will no doubt be asking more about this project as time goes on - so i apologise in advance.
