Here Is some Diagrams I made up For Led Mods.
More to come. :up:

Keep in mind, depeding on who manufacters the LED's, the markings are different, the polarity on my LED's is all marked with a cathode facing T, since they are made by toshiba (only the best baby!) lol Good Looking out Snakejockey :up:

This is for i60,i90 & i95's :up:

does anyone know what size LED to use to do the front LCD? they are bigger then the 0603 :thinking:

You could use the same kind you use on the keypad :up:

Ok few questions
#1 Can you change the status lights? I would like to have white for service and blue for no service.
#2 Can you chang the backlight color on the LCD? If so how?

And where can I get LEDs at? And the resistors?

Thanks guys,
Joel

#1 yes you can. you can also ad a second status light on the other side of the phone.
#2 you can change the backlight on everything but i90's

u can get LEDs from www.idenundaground.com

what are resistors used for?what are they?

they lower the current going to the leds so they don't get overloaded

If you want to add LEDs to the empty spots on the keypad, do you have to use a resistor? I figure it would just make it bright if you don't but they may burn out quicker. If you don't use a resistor, do you have to bridge the gap between the bottom two solder points? Thanks alot.

you have to use the resistors or your battery will go dead super fast plus you could fry the led and u put them in the same as the rest. :up:

Thanks! i'm going to give it a shot this weekend probably. :up:

idenundaground's shipping is a little slow, but i got everything i paid for. i don't know why, but it seems that some people have more problems with them than others do. i dunno :thinking:

DJJeffa, what size are the LED's and resistors used for the i95 and the i730? A numeric answer will work best as I know they are the same size as the phones keypad =P
What do you consider to be the highest quality brand LED and resistor?

djjeffa

03-04-2004, 06:57 PM

I use 681 resistors case thats what the phones come with of course you could go lower for a brighter look, as far as the leds i dont have a # I get them from iu.

Just found out both phones use 0603 SMT LEDs. They are much cheaper other places online if one is inclined to save money. =]

Next Question. I have a Hakko soldering iron that allows a variety of tempertures. I'm wondering what degree of heat works best for iDEN phones.

Yea what degree heat would be correct for ribbons(i95 cid leds, i730 cid leds)

I got carried away and forgot which end was where. I have a green led from an i205 and cant find a diagram anywhere. djjeffa, got any idea which is cathode and which is anode.

Here is a rough diagram. VERY ROUGH

lol , thats a verry accurate drawing !

o.k. then ,which side is anode :aw:

djjeffa

03-07-2004, 03:17 PM

ok simple wat to find out grab it with a tweasers and power up the board buy holding a batter to the back or use a rubber band to hold the batt on then with the tweaser and the led hold it to the solder joint see if it lights if not spin it 180 and try :up:

ok sorry for a double post. I was taking the leds off of my i205 board and when I did one, the pad that is on the board came off too. Does anybody have any suggestions? I was thinking about putting a wire to the resistor to power the led . What do y'all think? :D

thanks for the help djjeffa :up:

so I guess running the wire worked?

Partsman

yeah, it worked. Thanks again man :up: I think I need a Magnafying station. thats some small ass wire. lol :mrgreen:

hm... im using a broken board. and my soldering pen is all rusty and dirty so i dont know if im duing it right
lol and im not sure if im removeing the pads which is bad.

Any one wanna post an upclose pictorial?

sorry for posting really late...but how would i add the second status light to my phone? also... which one is the flashing green and which is solid red....lol alsoo.. fi i have the LE status light hack... what would happen when that is run with the new LED's? thanks...

Alrighty no clue what a LED is. LCD i think i may have an idea, but I really have no frikken clue what you people are talking about. Not really down with electronics, but willing to maul a few phones to get it down. Someone want to message me and let me know whats going on? haha word. =)
