DIY CD drive based on a computer CDROM

[Nuuk]

Just a thought but wouldn't it be better to have the control buttons on a daughterboard that would maximise the options for building the whole thing into a case?

Lupulroz,

What transformer are you using? Any source? Also, does the board support a backlit LCD or do you have to run separate power to it?

 

[Lupulroz]

The transformer is just an ordinary one with AC output 9V & 12V.
You can add wires to put your buttons anywhere you want.
The LCD gets the power also from the board.

 

[UrSv]

Does the low voltage have to be 9 VAC or could you use a dual 12 VAC transformer?

 

[Lupulroz]

You can use also dual 12V but the dissipation on the PSU will be higher..

 

[UrSv]

Thanks. I'll try and we'll see what happens...

April issue of Elektor magazine seems to publish a very similar project to the one illustrated in post #410 & #411.

However, I couldn't get my hand on one example of the magazine yet so I'm not sure if it supports remote control and/or LCD display.

Any one here has more info ?

Elektor (Elektuur) CDROM audio drive

Hello Elkaid,

The player described in Elektor does not include an LCD display. The player is intended to repeatedly play the same track. These tracks have direct access via 8 buttons. So button 1 plays track 1, button 2 plays track 2 and so on, and so on. They do provide the software source on their website and some information regarding IDE programming. That might be usefull.

Cheers,
Michael

elector is difficult to find-- too bad
seem like that and the mucop are the open source choices
or perhaps some of the atmel or 8051 versions in early posts

<little rant:> there is only one electronics mag left in north america but try to find N&V on the shelves despite its stupid price
almost double circuitcellar for example
and check out the canadian subscription prices
<end rant>

O.K. here's the site

http://www.elektor-electronics.co.uk/

the link to the software for this months issue is

http://www.elektor-electronics.co.uk/dl/details/dl0404.htm

Hope this helps.

They also have an article about a high end preamp based on a microcontroller and a volume control IC called PGA2311.

Might be interesting for the gainclone people out here. I gues the chip could act as a buffer.

Cheers,
Michael

help!

hi,anyone would like to share their bugs free source codes of project Mucop?headache

 

[davesaudio]

Here's the direct link to the Elector download
http://www.elektor-electronics.co.uk/dl/details/dl0404.htm

download the "pandora" bits

My ideal "kit" would be a board I can buy and working code I can modify to my heart's content- this is audio DIY afterall...

Start to decorate transporter

After finished my control board, I plan to make top loader transporter from this simple one.

So simple to start to use my control board.

 

[pradit_p]

Open your cdrom.

You need to decide by yourself to open cdrom case because most of them in Thailand warranty void if open case and most of all ...
DANGER..
Visible and invisible Laser Radiation when open .
Avoid direct explosure to beam.

 

[pradit_p]

Preparing case

Next prepared Case..
Tomorrow I will prepare some part to assemly..
I 'll be back

Great looking player

Nice one Pradit_P,

What kind of case are you using beneath the acryl?

Can't hardly wait to see more,
Michael

 

[pradit_p]

Hello Michael
That 's universal steel box that can bought in local electronic market.

Glad to see you like it.

 

[Nuuk]

Great idea Pradit! I converted my CD723 to a toploader a few years back and it made a real difference.

I plan to go with a converted CD Rom drive as my next transport so will be particularly interested in how you progress.

 

[docdune]

hi pradit_P,

great stuff youre doing. Is your project open source? If so could those of us interested in real diy get access to the schematic and pic source code or firmware. I would sure love to built one of my own.

Thanks

Just reporting that the CDROM controller in post #412 is working just fine. I tested first with a Sony U-710 which played some tricks and basically didn't work at all. I swapped it for an ASUS S520 (as shown in some other posts) and it works just fine. Only problem which suprised me is that the CDROM is vibrating and making quite a lot of noise at 1X which I did not expect. Maybe it's just this unit...
