I read somewhere that the DC gives its LED 3.3v, and that I need an LED that produces at least 1,000 mcd, but I'm not too familiar with LED specs or how bright 1k mcd is. I was thinking to order some LEDs online for really cheap, but I'm not sure what to get -- I see listings for 10k-18k mcd LEDs, and I don't want to turn on the DC to play at night and end up blinded by the bright blue light on the front of it that outshines the TV or something.
Any thoughts?
First I'd recommend getting all the stuff needed such as the soldering iron etc and the LED(s).
Few things you need to know Nightsail, and anyone else reading this.
LED's are 3V and yes for any other LED mods such as controller ports, and the fan led mod etc you will need to use the 3.3v pin from the power supply. For this you will need the correct resistor aswell.
But before you de-solder your original LED off the controller circuit board. Make sure you have a solder sucker gun. TRUST ME!
Then make sure your LED goes the correct way around, yes, one sides + (Live) other sides - (Negative). I found this out the hard way as none of the tutorials out there state that it has to go a "Certain way" including this instructable... -,-"
As far as I'm aware (Correct me if I'm wrong) The "LONG" leg on the LED (one legs longer than the other) Is the Negative ( - ) and the short leg is the Positive ( + ). - To be 100% sure or to test this, get a 3V flat battery and stick the LED on either side. Only 1 way will work. The battery should be marked with a + on the positive side. Remember the + goes to - in a circuit so the leg touching the + side will be the Negative side, and the leg touching the opposide side (aka -) will be the Positive leg. (Should be the short one)
Now you need to make sure you wire the LED the correct way. The long LEG (Neutral) goes on the A (left) side of the A-( * * )-K * * = holes for the legs for the LED. and the Short leg (Positive) goes on the K side. However you can check this (BE VERY CAREFUL) you will need the Dreamcast powered, and with the controller board partly out so that you can access the bottom of the board however it needs to still be plugged in. (Not sure the fans too important but I make sure its plugged in aswell as the ribbon cable). Then put the led legs on the pins already there (soldered) for the original led. Remember which side is A and which side is K (This is marked on the top of the board) With ports facing towards you, and the fan socket on the right, A is on the Left, K is on the right near where it says LED1.
See where the "wires" or contacts go on the circuit board, you'll see from the left there's 2 going in and on the right there's only 1. Put 1 leg (short) on the left bit of solder / pin. And the right leg on the other pin. If it lights up, it's the way you solder it. To double check, keep the short leg on the left LED pin (A) and put the right leg on the soldered pin along the single line (the first one you come to) again this should light up. Your original LED may go out but don't worry about this.
So once you've found the correct way to wire it up. Make a note. But providing your LED legs are correct, the short one being N (A side) and the long being L (K side) then desolder your original LED becareful not to touch the board with the soldering iron. I torched parts of my board which made it harder to solder the LED in place because I had to apply extra solder to get past the burnt parts so that it worked.
IMPORTANT! - Learn how to solder, before soldering. It's not as "Easy" as people make out. Remember, something is only EASY if you know how to do it. - There's youtube videos and articles on google. You need to heat the component leg / pin with the iron and apply the solder to the component leg/pin not the soldering iron. This will ensure a neat solder point is done.
But practice first and do your research. It's only a LED mod, but trust me I learnt the hard way by diving in head first. I had to de-solder an LED throw it away and re-solder another one in. All this in-experienced soldering torched part of the board / connections which made it harder to then get the LED soldered and working.
I will be doing a youtube video on this so if anyone is interested then be sure to search me: MikeyB2k9 on youtube. I'll probably upload it within 1-2 weeks of this post.
Hope all my info's helped anyone out there... Just be careful guys, you don't want to screw your dreamcast up for the sake of 1 LED. However if you want to do further mods, I recommend doing this first to get the hang of things. Or practice soldering / de-soldering on something else, a scrap circuit board or something not so important and rare as a dreamcast.
Enjoy!

Just one thing;
you're messing with original retro hardware, you heretic!
