Hi all,
I've no real knowledge of electronics, however i've decided i'd like to install some LED lights on my Playstation 2 (although am currently considering the modding possibilities of just about every piece of electronic equipment in my home).
Ok, so my questions are:
A) I used a resistor calculator online which told me (after I punched in 12 3.3v 20mA LEDs coming off a 12v supply (no idea if that's what i'll be using)) that i'd need a 1/8w, 330ohm resistor. I looked on my local electronics store website and the resistors aren't listed by wattage or by Ohm's (Well I do see Watt's but I think 10 might be overkill ), so how can I tell? ps. The site i'm using is http://www.maplin.co.uk.
B) How do I connect a resistor to multiple LED's? Wrap the resistor around all the positive legs and solder? (Guess, based on what i've read) But then what do I do with the negative legs?
C) How can I use a multimeter to find a suitable component on my PS2 to solder to the resistor? I understand i'm looking for the small silver ball-like components (god i'm a newbie), but how can I tell which is negative and which is positive? And can I use any positive and negative component which is the desired wattage, or do they have to be next to each other/corrospond to each other in some way. Also, should I just measure the watts? I'd love to know how to do this so I could take apart my GBA next and put some cool stuff on it.
And I think that's me for just now. Anyway, really sorry about the length of my questions, just want to make sure I get everything down before I get to grips with it.
Thanks
Jamie
