Ok question 1 yes it seems like a dumb question but I want the best viewing angle to get the most light from a jewel
do I solder to the top or bottom of the 0603? also which side do I glue to the PSP UMD door? do I I glue it sideways? bottom on the door? top on the door?
Ok also I have 7 0603 LEDs and another with 7 0603 LEDs also both on separate circuits. So for the one with 7 LEDs from the 5v spot on the slim how many ohms do I need to resist if each LED is 1/8 watts each? I used this cac:
http://www.the12volt.com/ohm/page2.asp and got 28.57143 ohms how many is that? do I round it off?
I plan to have 7 amber/yellow LEDs, 3 in UMD door 2 in triggers and 2 in bottom light like the "cleaned up my PSP" thread, then 7 green, 2 in bottom light 3 in UMD door and 2 in speaker holes. All these green/Yellow will be sound reactive and on separate circuits.
Then have 4 (another set) of yellow fader LEDs, 2 in bottom light and 2 in triggers.
total of 18 LEDs
So I need to know what size resistor to use for 7 0603 1.8 watts (each) LEDs coming from the 5v spot on the mobo.
