BlueSCSI v1.0-c external LED?
- Thread starter reallyrandy

That's what I was looking for, thanks. Don't know a lot about the hardware part of it but I'll see if I can make sense of it.
OK, so if I attach the LED to the 5v & GND circled in the photo that's just for power, right?
It says "you can use the same pin, PA0 as 1.1 does, you will have to solder it yourself" but I don't see a PA0.
and it says I'll need a resistor rated for my LED (between 300-500 ohms. I know very little about that sort of thing, any recommendations for a resistor for the built in SE/30 LED?

PA0 is Pin A0, this is for activity, which I assume you want.
You seem to be looking at both the power and activity sections of the link I sent, pick the one you want that LED to be and follow those instructions.
Lastly, we'd usually just pick 330ohm resistors - something in the middle. You'll need some resistor or you'll burn out the LED. Unfortunately it depends on what the LED is rated for so I cant just tell you the resistor to get. But 330ohm is generally safe, though may be a bit dim. You can usually pick up packs of resistors of varying values for cheap - handy for projects like this.
