DIY CD drive based on a computer CDROM

[-_nando-_]

Zanuda, I wish I could write my own code... Keep writing, I imagine that it would be a great satisfaction for you.

From my recollection the original "on hold" and elector's "pandora"
were some of the better commented code if you wanted to follow the logic/reverse engineer

My aussie friends tell me the silicon chip article is built on a mega 8515

yes you need an eject

so much code has been written do it from scratch again why?

Dave
have you seen(read) the article?

Sorry I have not seen it. I would have bought the article online if the source was available but that appears not to be the case.

I prefer learning by hacking at existing working code in small increments, this might have been a good intro to ATMEL UC's for me

alas....

There is no source code there. It is a HEX file. For those not familiar with what that it, it is an ASCII representation of the binary object code. Just a step removed from the binary image itself and of little practical value for software development purposes.

Hi all

I'm arriving a bit late on this thread but if anyone is interested in such a DIY project he/she may want to have a glance at what I've started a month ago.

Some details are still to be finalized, like choosing the display type (LCD, VFD ? I have both and I'm undecided) but the thing plays wonderfully well at the moment 🙂

Here's a link toward the page : Diy CD player
(sorry, it's currently in french but I intend to translate it some day).




And a picture of the (almost) completed project a few weeks ago.

I WANT ONE OF THESE CHASSIS!!!!!

TESTING NOW

Hi. I'm using ADLABS KIT which is based on a PIC u-controller.

http://www.audiokit.ro/cdrom.html

All is ok, both with CDROM and DVDROM exept on the following: it is able to play only original music CDs. Nothing to do with Music copied on CD-R. ALL CDROM drives seems not to be able to read....... I cannot understand.

Why?

If it is a true cd copy then I would suspect you are using a very old CDROM? Some were intolerant.
Try to burn a RW I have a sony that will only read those

I have this CD adaptor. There's a bug. Power it with the tray open, and you'll see that the software crashes ! 😀

Mine works with any kind of cds... But I didn't learn any thing with this, as the source code isn't available.

 

[Gidu]

This is mine ...

And this is mine ...

An externally hosted image should be here but it was not working when we last tested it.

Tadaaaaa !!!

-_nando-_: it seems that you hit another bug which makes this list longer
Anyway, here are some hints to build you own CD-ROM/DVD-ROM controller.
Regards!

@ Lucifix

WOW ! I didn't expect for all these bugs (I'm refering to audiokitlabs controller)! 😀

I've downloaded your ZIP file which includes source codes for PIC16F and 18F and the schematic. Did you modified the code to run without the LCD?

Best Regards !

 

[Lucifix]

Did you modified the code to run without the LCD?

No, but I can do that if you want... I hope that I will have some time at the end of this year to play with.
Regards,
Lucifix

Hi Lucifix !

I was looking your site, that DAC looks amazing, very solid and professional. Do you have any other products? Congratulations !

Would be nice to have also a "non-lcd" version 😀

Is the source code open?

 

[Lucifix]

I was looking your site, that DAC looks amazing, very solid and professional.

   Thank You!
I will try to change that firmware to work without LCD as soon as possible... but I believe that this will happen at the begining of next year... 🙂
Have a beautiful day!

NO CD-R Reading ADLABS KIT

Hi!

Is there a possibility that the reason on this depends on Controller code?

I've tried with:

- NEC Lite-on DVDROM (no CD-R reading)
- NEC Lite-on CDROM (no CD-R reading)
- HP CDROM ((no CD-R reading)

Nohing to do... the CDROM continue to spin and stop cycling...

Should I try with PHILIPS OR SONY CDROM? (Hard to find nowadays)

 

[-_nando-_]

Probably you're using a different firmware version than mine.

Remote control

What type of remote control work with the project?

That project was designed to work with Philips RC5 compatible CD-Player handsets (see picture below). Here are some details.
Have a nice day!
