Hello,

about 10 Eur: 7 Eur for the part + 2,6 Eur postage ( but it can be less).

Regards
Stefano
 
How nice! different intensity each LED.
I've put a Feedback, but does not appear, maybe I do something wrong.
 
hi !

i come back, here, i just installed my Led and got a little Prob :

The Middle Red led is non working :



The same thing appears with the Old LED Adapter and it was for that i bought a new one.

So i think the prob is not the Adapter but my A1200.. Any Idea ?

Hello Foul,

nothing is faulty, and your old LED pcb is ok and you can sell it here very easily. My solution work in this way: in the middle of the harddisk activity LED there is the LED for the PCMCIA cards. This LED need to be activated by this mod

http://www.doobreynet.co.uk/extraled.html

otherwise, you can put a card on the PCMCIA port but you will see nothing about the activity of the card.

I repeat, if you are not satisfied about my solution, i think, the best move is to sell this adapter here on Amibay. You will sell it very quicly!
I have here two or three PCB that are like you wish to have, without the PCMCIA activity LED. I can build one for you.

Hello Foul,

i wait your response, done the mod!
By the way, on the first post, there is all explained!

Stefano
 
No prob.. will post after the fix done ;)

edit : Fix done but Led not blinking :(



I tryed to invert Red/blue one and the Middle Blue at the bottom not working anymore :Doh:



i'm sure i made a mistake...

Hello Foul,

try with a multimeter, with test diode, to see if the middle diode is ok! If yes, it is only a question of logic on the A1200 motherboard.The user Obiwan has sent a video, try to ask him! I do not have a PCMCIA card, so i can tell you nothing!

Now, i have seen the video! Just to explain: there is two red and one white, because the PCMCIA LED (white) is not linked to the harddisk LED (red), so i have choosed two different colors.
All the LEDs are ok! It is only an issue of the mod!

Hello Foul,

what mean? Wish to have a LED board without PCMCIA LED? If yes, you can try to sell here the parts that you have bought. If, in a couple of days, nothing is sold, sent to me the two boards, then i will build one for you without extra LED and i will refund you for the other LED board.

i explain : you sent me a board with :

Power : blue/blue/blue
Floppy : white/white/white
Hard Drive : red/red/red

like i requested.. no prob...

i swapped the blue and red leds and added a white led (taken from the old board) in the middle to obtain :

Power/pcmcia : red/white/red
Floppy : white/white/white
Hard Drive : blue/blue/blue

but i think i made a mistake because now, the two red leds are blinking low.. et the white one (PCMCIA) not blinking at all ! and my PCMCIA WIFI Card is inserted and configured... not a problem of PCMCIA...
and the middle blue led is not blinking too...

it's not your fault but mine ;)

What king of colors are available other then red/blue/white ? is there any Yellow or Orange ? I think to buy another board to you but need to know what differents olors are availables :)

edit: i'm just thinkink something...

is the PCMCIA LED in the middle of Power or Hard Drive ??? i though it was the White Led in the middle of Power but i was wrong, it's the blue led blinking very low in the middle of hard drive !!! i'm right ? If so how to give more power to the PCMCIA LED ? remove resistor from this led ?

My mod looks like this:

A1200_Mod1.jpg

A1200_Mod2.jpg

I used 1x 10K resistor (left) and 1x 4.7K resitor (right). And BC327 transistor.
That's all.

Edit: middle led is PCMCIA, left and right is HDD.

Hello Foul,

there is many colors that you will find on Ebay, but, bright like what i have used, there is only four color: red, white, green and blue. The value of the resistors is calibrated with this type of LED.

Re-checkek, re-wired all and everything back to normal or near ;)

Just one thing.. the Red LEDs are not very bright... just check this video :



And the Hard drive Leds (Blue) are blinking very low even when hard drive is not in use...
 
I have one CF-IDE adapter with this problem. Tested in A1200 and A600 with same result. Replaced with new one adapter problem solved. Have you this problem with original leds ? Or try to disconnect the PCMCIA led, and see what happens, for sure.
 
Hello Foul,

the blue light is the most intense light, then follow green light (a little bit less intense), white and then red, that is the less intense light.
Blue LED need a high value of resistor to attenuate the brightness of the blue light (i know, that is trivial but...), red LED need a very low value of resistor. If you change the position of the LED, you need, on my board, to change the resistor.
