Hi nFORCE,

Your website was totally unreadable to me, what language is it in?

Also what does your project do?

[rendisha]

Hello nFORCE,

Please translate, at least, part values in cir.pdf file, because some of them are hard to read on pcb.

As I see from source and schematics it does what it should - play, pause, next, previous, stop, eject. It's the first time I saw only those routines without all mp3 related stuff

Is that your site. If it is, does it work OK (is it debugged)?

Thank You.

check my site http://audio.neora.ru/projects/cdplayer/hard.htm


P.S. Russian language

[madalo]

ditter,

Nice player - though i cant read the Russian language, i love the page, nice fonts!

i made a player similar to this last year, but with raw lcd driver micro

people might also check piclist for microchip code to run a cdrom

We use at89c52 or at89s8252 by ATMEL
PCB & Shematics here
LCD made by http://audio.neora.ru/cgi-bin/goto.cgi?what=6 very nice fonts (9mm) & price
mirocode is http://audio.neora.ru/cgi-bin/goto.cgi?what=24 but his NOT SUPPORT CD-TEXT (as you can see at foto ) sorry but code with this feature not shareware
P.S. my English is very bad

Is there any disadvantage to using a cdrom for audio cd playback?

I see creative has a IR remote model and I was thinking of putting it in a nice box rather than buying an expensive transport or building the homeoptics kit.

I disected a cdrom and removed the tray the other day. It worked fine as a top load transport. I havent tryed to get the digital signal off of it and I dont know if this is compatible with an conventional audio DAC.

Any ideas? Cant get a clear answer to whether good vs decent transports produce different quality data?

I'm sure someone will jump in here to say YES, but I just can't see how - I mean, if a CDROM gave you DIFFERENT readings (numbers, values) for different manufacturer's drives, then you'd have a real big problem, no?

hey where can i get teh schematic for this id like to try it. i was just going to take the audio out of teh back and put taht into my pre amp since all you have to do is press forward buttin and it will start playing cd.. done it befor for simple plesure uses..

J' id like teh schematic for teh pcb and ect ect and the parts use to create desplay.

From what Ive read there is correction software that will do some interpolation before the unit audibly misreads. The MArk Levinson site talks about the data getting clocked inacurately if the transports clock is not accurate. Then I guess the DAC might spit out a sound at the wrong time?
