DIY CD drive based on a computer CDROM

I started to make a CD player based on a CD Rom when I found this thread. I hardly ever use any other buttons than play,stop & Eject so I thought it was going to be easy. However I did not consider things like faster than 1X reading and the fact that the damn disc will spin in the CD Rom even when you press stop. Also problems with copy protection bypassed me.

I've had a look at MCLL's controller, you have a very neat thing there!!

Does it deal with copy protection issues & does it force 1x speed to read CD's.

I have never programmed a microcontroller before and my programming experience is learning basic in primary school, I was about 8 yrs then and thats many years ago.

I was hoping this could be a good introduction for me. I've downloaded the source code & the diagrams. Apart from a suitable programmer with software and the will not to end it all if it goes wrong, can anyone give me some pointers.

Things like useful advice, places to buy a simple but good programmer etc etc.

All I have to offer so far is a pic of my project as it stands. Its a bit of a no brainer at the moment. I got a 2U rack mount case and lined it with chip board & made a chipboard plinth in the middle to raise the cd rom. It's going to be a top loader. I removed the drawer and intend to modify the opening mechanism so that it locks the top cover on the case rather than ejecting the disc.

The PSU is a switchmode that I hacked. I played around with various ideas before I got this far. Each cap is 3300uf & the 1st stage is a RC filter of 6600uf & 1.2R. The resistors are on the small heat sink. The switchmodes output without the filtering was quite good. I was surprised at this. With the extra filtering and shielding the output is very clean as far as I can tell. My scope is basic and measures down to 1mv and can give noise figures down to -75db. I cant even get a noise reading with this supply.

Hopefully it wont be long before I have a decent controller for it.

Then its the DAC but thats anothr story.

Cheers Paul
