MC activity LED?

[AutoMX]

I remember a japanese tutorial on this but cant find it.. Anyone know the site or have diagrams in english [or engrish]? Thanks for the help.

[ps2daddy]

Never seen it but I am sure that if you use a multimeter and probe the pins onece you open you should be able to find which points give you 5V and solder an led with a resistor to it and that should work just fine you have to drill a hole or something to mount the led proably though

[ps2daddy]

Try this
http://sami.ticalc.org/e_pxpand.htm

I saw that there is a 3.7 and a 7V power point you have to find the right resistor and see what works 100 Ohm would probably work fine but you need to know current load for your led to get exact numbers

*Other considerations
You might have to solder the connection to the data line instead of the 3.7 or 7V points the pinouts for the ps2 memory card is in that diagram on that page

i remember the mc activity led also. i was searchign for it but i guess it was lost in the move

[loy]

can't we just slap a transistor and be done with it??

[juandelacosta]

here it is

[loy]

thats the tuturiol

[MaCe1337]

ooh, engrish *slaps it into his engrish collection* :D
But seriously, it looks interesting enough, however, I couldn't understand a word of it. I'll just copy from the picture :) Blue led powerrr!!!!! :p

[juandelacosta]

sorry just copied it from that original site ages ago. i didnt edit much

[EspI69]

how about puttin an LED inside your memory card wit a hole so that where ever u take your MC , you can see your led glow.

any ideas

well, that´s what the .doc shows right?

[EspI69]

is that pic from the .doc juandelacosta posted?
i looked at the .doc but i see any of the pics, any got a pic of the inside of the MC soi can see where to solder an led inside the MCD and in my ps2?

yes it is actually, i´ll attach the proper pic....
edit: These are all of the pictures in the word doc....

[EspI69]

dude, that rocks, thanks for posting those, i couldnt see them from the document.
im going to be doing this mod in a few days , gotta hit up radio shack and get sum LEDs , and solder.

can i ask you a question.
would u be able to tell me how powerful that led is?
and the same for the resistors?>
so this way i can mimmick that same set up.
(the document is kind of hardto understand.)

No problem mate, glad I could help out.

As for the values:
You can see a diagram with the values in pic 2, the LED i don´t know really, I didn´t understand the doc too well... I guess you should use a 20 mA led or something, but i don´t know the voltage....

[EspI69]

has anyoen on here done this mod yet? if so , what exatly did you use,(led ,resistors)

[MaCe1337]

For the resistors use 10K Ohm and 330 Ohm.
also, get a 2sc1815 transistor.

As for the led, get a 3mm type, I used a 650 mcd royal blue LED. It´s maximum current is 20 mA, but it lights up just fine if it gets less. So just try to get a led with the colour of your choice, but small enough (3mm) and it should work fine :D

[EspI69]

kool. ill be at radio shack as soon as they open lol.u said you did this mod, have an y kool pics to entertain me till the shack opens

[MaCe1337]

Wish I had man, i´m too cheap to get a digicam, when I get round to it, i´ll get a mates digicam.


BTW, if you have problems fitting in your led, don´t hesitate to file off the top lens part of the led... as long as you don´t go all the way down to the metal thingies (anode and kathode) :)

[EspI69]

ill be buying this in a few hours lol... prolly do it in like 10-20 mins. .. you know any other MC mods? i might paint it i dunno.. ..kindda thinking of cuting out the rectangle shaped lable spot on the front of it and puttin sum sort of thin window... but i dont know what would be that thin. (maybe that clear plastic that comes on envelopse you get in the mail where it covers your mailing address but you can see thru it and it kinda crumples a little. usaully on bills lol) i dont know if that the best way to do this. think its worth it?

[MaCe1337]

Well, it would be fun to do, but because the crumple plastic is so fragile, when you would want to pull out the MC, you´d break the plastic :p. So you´d be better off trying to find some thin plastic. then again the underside of a PCB is not terribly interesting, is it?

What about putting a few bright leds in and drilling small holes all over the MC?

[EspI69]

ooo yeaaaaaaaaa, i just noticed its u underside, stupid me! lol i forgot its lifed upsidedown when in the slot. it would have been kool to see the other side glow tho.
:(

[EspI69]

ok, what if i put it on the underside of the MC, where it has that silver sticker saying ps2 8mb blah blah chinese letters. . its be kool, plus i never relly remove my MC , its been there for ever. loli only take out the second one. and if i do take it out, i can grab it on the sides, but i dont know what kind of plastic id use..or where i would get it.

[Thinkdiff]

Ok, i tried this mod and i get the LED on all the time. I think it might because I have a different transistor. I bought a pack of 15 from radioshack, NPN type transistors. I looked up the spec sheet for the 2SC1815 and it is also a NPN trans. but it has a different pin-out than the one on the back of the radioshack box. for the radioshack ones, pin 1- Emitter, pin 2- Base, pin 3- Collector. according to the spec sheet, the 2SC1815 is pin 1- Emitter, pin 2- Collector, pin 3- Base. Am I correct? I switched the 2 and 3 pins and get it on full time. do I need to ahve the other transistor for this to work?

[EspI69]

DUDE , WHERE DID YOU SOLDER IT 2? I CANT SEEM TO FIGURE IT OUT. I JUST NEED THE led TO GLOW, IT DOESANT MATTER IF ITS ALL THE TIME OR ONLY WHEN THE mc IS USED. I POSTED SOME PICS AND INFO HERE http://ps2-scene.org/forums/showthread.php?t=25357

LET ME KNO WHAT YOU BOUGHT AND WHERE U SOLDERED IT... ITD BE KOOL IF U HAD A PIC.

[Thinkdiff]

I followed the picture that has the actual layout exactly, except I had to switch leg 2 and 3 (middle one and one farthest away from the board) to get mine to light up (all the time).

I bought a 100-pack of resistors (assorted, I used the 330 and the 10k as specified), one 3mm Red LED, and one transistor (from a 15 pack of NPN transistors) all from radioshack.

[EspI69]

ok , but with the resistors, does it matter if it says 5% tolerance?
and for the transistor... what numbers does it say on the back so i know which transistor to use becuase i cant find the 2sc1815 as i was told to use, ive tryed 2 radio shacks and cant find it.....can i just use any other transistor?

[Thinkdiff]

I'm not sure what it says. I just used any of the ones from the 15 pack of NPN-type transistors. it was a couple bucks at radioshack.

the resistors are supposed to be 5%

[loy]

Do you know how transistors work?? maybe u have the transistor wired up wrong

[Thinkdiff]

Do you know how transistors work?? maybe u have the transistor wired up wrong

Yes, I do. Usually you place legs 1 and 3 in the circuit and then leg 2 either turns high or low completing, or disconnecting, the circuit. I need to know if the pinout on the 2SC1815 being different from the one I have is going to affect that. and if so, how to fix it.

[eight_heads]

let's see some pics of this mod finished guys...

[EspI69]

i just put the light and instralled window on my ps2 , ill probably try doing the MC mod 2morrow

[fragment]

nice, been looking for this for a while...

[fragment]

what pinouts for light all the time?

[Purple Penguin]

lay your memory card donw in front of you face down with the contact points facing you. counting from the left the 4th one works for your power (the first in the second set of 3) and the 5th works for the ground (the center point in the middle set of 3)

that's how I did mine anyways and it works like a charm

[Thinkdiff]

I still have my lit up all the time cause I never figured out how to wire up the transistor properly.. All I got was a "do you know how transistors work". :\

Maybe i'll try it again some day.

[EspI69]

ohh o i got it... instead of using points on the chips...u used the contact pads forthe power....whats the voltage on that when its runnin?> u just attached and LED to it?

[Thinkdiff]

I got it!! I modded all three of my memcards with activity LEDs.. I'll post some pictures/movies in a bit

[eight_heads]

let's see them :p

[omegatron]

someone please redo this tut

[eye_fling_poo]

right click and save doc file This might help (http://home.comcast.net/~97gts/Memory_Card_LED.doc)

[dick_onion53]

Great guide. I'd like to see this in action...

[105854804]

i have a question:
which pin on the transistor should i connect?

the emmiter is to the led (point 2 and 4), that's for sure
but how do you connect the other 2 pins?
base to 1 or 3? collector to 1 or 3?

for the numbering, see attachment

[105854804]

did some research, found something, and made a pic which could help people the MOST, i guess.
figured that there are too many pics and when u install it u need to look back and forth for the right place to iron.
guess this pic will save u guys some time.

oh and BTW, if any of you have extra Resistor, blue or green LED, and Transistor that meets the standard, please DO email me, cant find any electronic store here in malaysia.
yeayearite@hotmail.com

[omegatron]

thanks for that pic
Also what strenght led should i s use is 25mA to high??? 7000mcd blue is what i want to use

[eye_fling_poo]

The first time I did this I followed this pic (http://www.ps2-scene.org/forums/attachment.php?attachmentid=7438) , it didn't work and I thought I killed my memory card :cry: . The Collector and Base were switched. After I figured this out I did this (http://home.comcast.net/~97gts/Untitled-1_copy.jpg) and it worked. I have since done this for all my friends, they had to have it after they saw it.

276-2009 - NPN Transistor MPS2222A $0.69
271-1335 - 5pk 10kΩ ¼ watt resistors $0.99
271-1315 - 5pk 330Ω ¼ watt resistors $0.99

And A 3 volt LED of Your Choice, I'm not sure of current limitations.

I used: [I filed it down to a rectangular shape to fit pic (http://www.ps2-scene.org/forums/attachment.php?attachmentid=5534) ]

276-316 - Blue 2600 MCD intensity, T-1-3/4 (5mm) size LED $4.29

Wavelength: 468mm (typ.), Type: T-1-3/4 (5mm), Lens Color: Clear, Viewing Angle: 30°, If mA: 20 (max.), Vf: 3.7 (volts typ.), Vf: 4.5 (volts max.)

[andreq]

For all folks that wanted a video of this :
http://membres.lycos.fr/csclanbef/files.html?dlFile=Electronique/MemoeryCardMod.rm

I did it like 2 month ago ...my post got lost (I did a search to find it)

got unsoldered and now my MC is working without it... Il redo it with some kind of smd transitor i think... and 30awg wire for B point.

p.s. you need real plugin... (try real alternate)

sorry to hear u fried ur MC...but u should do some homework before modding it...if you look at my second pic which is this: http://www.ps2-scene.org/forums/attachment.php?attachmentid=7439,
i think u should know that base is supposed to be connected to the second pin-foot and collector to the led, not the other way around. if you look at the llittle black-background diagram on the first doc, together with the photo with the ABCD point on it, u will also understand it. maybe its just that the transistors from different maunfactors have different pin-locations, but glad to hear u successed on the second try!

PS: still hoping my modchip is not fried and it is the lack of power which stops it from functioning. :-pray:

Um I didn't fry my MC if you read my post :chinscrat . If you took that pic /\ I guess your transistor had a different pin-out a TO92A type and I am using a TO92B type pin-out. The tut. I found months ago when I did this didn't give a pin-out for the transistor simply an A to A, B to B type instruction.

[105854804]

i successed!
finally got it installed, and it worked!!!!!
LOL!!!
now trying to apply the same thing to my ps1 memory card
