Another CDROM Controller Kit

DAC

Hi Pradit,
more then one year ago, i bought the kit from you - now i want to make it sing!

i want to build a CD-rom based player with some good DAC and additional output stage (CarlosFM design with two AD826).

What simplest DAC design you could recommend to use is such configuration?

thanks. Filip

Possible hard disk controller?

This looks like it could be promising for folks (like me) that would like to build a hard drive version of something like this.

Too bad it looks like the design isn't finished yet.

(edit: scratch that, one of their other pages has more information, and it doesn't look like it supports hard drives.)

Hi Pradit

Is this cd-rom controller still available?

Thanks

Depending on what Pradit says I have a kit gathering dust on the shelf after going a different route, we could come to an agreement 🙂

 

[Jempie]

What does it mean? you have for me the same kit?

Regards,
Jempie

 

[toolkit]

Yep, the one pictured at the top of this thread. I tried to email you but you have it switched off.

 

[Jempie]

OK,

I need to know the follow;

Does the remote works on RC5 code?
does you have and circuit diagram
and do you have the source codes of this unit?

Regards,
Jempie

Nope, I don't have any of that, just the hardware as described.

Hey Mr Pradit_P

Today i built ur CD ROM Controller using that free code.

Pradit,

I'd like to buy your source code, but as I'm pretty new here, I am not able to email you... Could you be so kind and send me an email regarding payment details (paypal?)

Best regards,

Jorn

I have the last board of rockna cd-rom controller
but i have a question on my board there is no transistor
placed on the board what kind of transistor must this be

and what can you do with J8 stand by

Time to Change...

Sorry For No Reply..

no time for hobby now.

So.. I will give source code for every one.. to study with Remote Code..

I 'm sure my code not perfect.. then If any one modify it better and better please repost or post your finished Hobby here.

Thanks..
