Convert ur pre/cassete player to USB mp3 player

[devilz_apprentice]

@poster, thanx alot for a detailed reply. i'll b starting this DIY in a day or two, i'll b grateful to u if u could help me out.

@ TheMasterMind Thesound quality is superb, much better than FM MOdulator

@ devilz_apprentice Sure sir any time

alaa yar..

[mysantro95]

wheres the aux cable. And is it fitted in a 2004 stock casste player of santro club

[illusive255]

@ z06 thanx sir

@mysantro95 Aux cable will be either on the back of ur system it would be like one shown in above pic or there will b an aux port on front like a headphone jack jack but only if ur cassete player has an aux option

[rusty_racer94]

I already have it.

[mysantro95]

@illusive 55. I donot have aux port on the front but there is a button on my casste player saying cd-c i.e cd changer. Do you think that it might have an aux cable behind.

[shree59]

my fm modulator have input on this point i do,nt have dany kindly help me

[illusive255]

@ mysantro95 sorry bro i have no idea abot cd changer input but if ur player has aux there must be a aux cable on the back if there is no port on front

@shree59 bro i have also input port on my FM modulator and if u look at pics closely the aux cables are solderd very next to that port

Nice Piece of DIY, that's a great mission acomplished...
Great work ... I will also try the same,
but do us update abt the Capacitors stuff...

[umerana]

nice work

[illusive255]

@ Zubair530 sir i have not yet tried capacitors. its an idea ll try and let u no

@illusive 55. I donot have aux port on the front but there is a button on my casste player saying cd-c i.e cd changer. Do you think that it might have an aux cable behind.

MOstly CD players on their behind have 2 connectors that are used for sound output when using amp...there is no input source behind them.....but i dont know your cd players model kindly mention it so mister illusive can say something about that
now a days mostly CD players have input on their front
like mine one

[zeekaykhan]

First of all thnx to all those who like my project

@ Guns On circuit boards for speaker output there are normally three soldering points one wire from both speaker cables attach to one point for that i have combined two wires from each cable this is same phenomenon as in ur headphones pin i.e. three points for two speakers as shown in pic

@ razaksyed yes boss ur idea is good i ll try if capacitor can improve the quality otherwise the quality is very good as compared to modulator but u have to solder the wires precisely at right place.

@ devilz_apprentice Sir to locate the sound out put points one must have a little knowledge about circuit boards. If there is any input / output port on ur FM Modulator the sound output points will surely be around that port and u can search by using a speaker with cables by touching the points on circuit board and about close up pics i only have the pics which i have uploaded coz at that time i was so much involved in my work that i forgot to take complete pictures.

Looks like there have been silent killers hiding out there

[devilz_apprentice]

Correct me if i m wrong, i think u hav connected the aux cables to the 2 channels of the input of the 2.5mm jack. Can u PM me ur number?

[Zubair530]

I got an MP3 Modulator yesterday@350Rs, and it has already got the Audio Out Pin place, so i dont need to do the conversion you have done... That Audio out pin can be connected to the auxilliary input of the Player... but when using AUX the sound get too much low....

[devilz_apprentice]

i used a speaker to locate the output. and all the following 5 points of the soldered jack input gave me the output. i am attaching the following pics, kindly let me whts the purpose of the points marked with "?(1)" and "?(2)". can these two points b used for the output? as the other three r clearly meant for the input via 2.5mm jack.

secondly, i joined the common grounds of the aux cables in the following manner. the middle wire constitutes the common ground. kindly let me if this is rightly done. Also, plz tell me where to solder these wires on the PCB in the first pic above?

[fahdlovespak]

good work done...........

[OptimusSS]

@illusive255
really well detailed DIY, thats what i call innovative thinking.

i have a question, i dont think my car has aux ports, anyther way of connecting them to the modulator. its a vitz 2004.

[aghashehraz]

ala yar now i will try tomorrow...
