rhythmic backlight for 3310

[HU-1]

wanna make your 3310 look like a 3350?

what i mean is that the rhythmic backlights eveytime the phone rings,

well just simple!

to make the best of it use all tranparen casings...

warning: be careful in connecting the wires inside the phone. avoid the contacts between the covers of the board with the
wire... short circuit occurs and it may shut down the phone and may damage the user interface IC!!!!


but is did it well..... just make sure of the things you are doing!!!!


have fun peeeps!

Thank you! Great job

Cheers for that i'll have to try it.

when posting pictures it makes sense to use any picture editor and save it as a jpeg. This file format makes the picture a lot smaller and quicker to download, without taking much of the quality of the original bmp.

[matt_016]

Cool...but I didn't understand the bmp pic.

So, can HU-1 plz explain more....maybe step by step...or anybody who understand???

@wwwanthony
Jpeg is usually best for photos, GIF for drawings.
In this case, original file : 462954 bytes
jpeg : 13153 bytes
gif : 4349 bytes

But I agree anything is better than a bitmap!
(I have a very slow "broadband" connection here - often slower than dialup... one of the few things I miss back in the uk is ntlworld!)

@matt_16
The diagram shows an LED (light) connected across the buzzer contacts. When the buzzer gets a voltage applied to it, it makes a noise. This same voltage also goes to the LED (s) - which makes them light. So the effect is that the lights flash with the music. It's just a case of connecting the LED leads to the buzzer in a way of your choosing - making sure that the LED is the correct way round or it won't light!

@HU-1
1) I would imagine that the LED would reduce the voltage across the buzzer, and therefore reduce the volume. Is this noticable?

2) There's no current limit resistor on the LED(s). I'm concerned that we can cook the buzzer driver chip by drawing too much current from it...

Oh, and a minor point about your picture - the arrows are the wrong way round. The arrow should be pointing away from the LED, not towards it, and the LED should be facing the other way round too :)

Otherwise, a great idea - and as you say, very simple!

no theres no effect in it!!!
the buzzer has much resistance than the led since it is connected in parallell, the current drawn is larger than the buzzer alone but yet, it is still ok.... ive been observing this for about 3 months from my implentation. you know im also an ECE.. I did the observation before posting this thing here... well sorry for the drawing.... i just did it rushly ..... so there it goes....

well thanks for your concern......
for those who dnt understand the pic... wait for my new post about this..... ill make it formal....

just a warning: do it and take the risk.... be very careful...

[HU-1]

here goes the new one.....

[matt_016]

Thanks...

Quite clear now....

AND can this be done on keypad light...making backlight and keypad light rhythmic???

[wwanthony]

It doesnt seem clear to me :confused:

Its just a blank white Bitmap.

Please check this or is it just my connection?

@HU-1
Thank you for answering my questions. I wasn't doubting your abilities or circuit, I was only raising some concerns about the current and the user interface chip. Glad it works for you :)

@Matt_016
It could be done with the keyboard and display LEDs, but the phone would require a little bit of surgery first. It's best to say no, it can't be done this way and just add new LEDs per HU-1's suggestion unless you have suitable tools for reworking surface mount components, very good eyesight and an extremely steady hand! :D

@wwwanthony
I just got a blank page too :D

[matt_016]

If U open with Windows Picture Viewer or ACDSee, it will show blank.

I use Picture Exhibitor MU v3.90 (www.oscarcreation.com) to view it. This is a VERY powerful graphic tool viewing/converting graphic file.

2 those who can't view this file, I've attached a jpg file instead of the original bmp.

Hope helps!!

P.S.

I'm still a bit blur with the pic. Maybe jeep/other can make a better pic (REAL PIC from Phone) and a clearer (step-by-step) how to instruction. I'm not a electric/electronic master, not idea bout this field!!

[mekme]

why not use an transistor (npn) from the signal (+) on the buzzer. to make sure the leds won't infect on the signal loudness.

[HU-1]

dont worry about this guys....

ITS NO PROBLEM......
thanks for your concerns......?
just do it and enjoy its result to your phone!


another thing thanks MAtt!!!!!

well for the keypad... ive been planning to do this since i started doing the rhythmic backlights..... i have this in mind already... i need a TTL digital IC numberes 74LS08 or 74LS32. its available here in davao but the problem is.... it is so big enough.. i want the small packages which could be fitted in the 3310 mainbord... i could do this if i can find this things....in your place if it is available do it..........in our place it is an ic package.. what i need is a chip. dont know if this is available. this 74LS08 is a TTL digital IC consists of 4sets of 2 in 1 out AND gates. all I need is just a 1 set 2 in 1 out and gate. guys if you could help me with this i will share the circuit with you!!!

Hardware is my FAVORITE...... `

yeah, we have the PCB flashing I/C here! it's built with a ic, and two transistors. it's quite small and thin that it can fit into a 3310, even a 8250!

[obeids]

check out the circuit i made and see if it would solve your problem.

the only thing i see that would not work is that both your display and your keypad leds would be on at the same tim but would still flash with your ringtone.

[HU-1]

what transistor did u use bro?

can u give us the value of thins amall thing?

thanks!!!!1

[obeids]

guys i use a BC 337 or BC327. one of them is a PNP and the other a NPN. you need and NPN. find out from the guys which one is which.
