tropicalrips 0 Report post Posted October 17, 2003 hi guys got a new challenge for u here i hav a CD-Rom connected to a headphone amp using its line out, but i want to hav the play - stop - next track - previous track funtion, without using the PC i already hav the case ready with the Rom install, together with its own ATX power supply, i also hav a small PCB board in there that taps the 12v from ATX to power the amp, the voltage can be adjusted for different amps, from 3 - 12 v Share this post Link to post Share on other sites
tropicalrips 0 Report post Posted October 17, 2003 (edited) here are some pics of the setup the amp is a Rolls HA204, this is ment for daily use, not really high-end stuff, i'm also thinking of putting the amp into the case since there is enough room in there, anyone got ideas but first i hav to figure out how to control the player, now i just use the play & stop buttons infront, but i think these can be controlled from the IDE port of the drive Edited October 17, 2003 by tropicalrips Share this post Link to post Share on other sites
N@Z 0 Report post Posted October 17, 2003 Now that's something different! A lil bit of matching timber tone lacquer & you have a nice compliment to the ATH-W1000! Just wondering whether putting the amp inside the enclosure would cause interference. Sorry I'm not much help here, hopeless at DIY me. Share this post Link to post Share on other sites
tropicalrips 0 Report post Posted October 17, 2003 u think Audio Technica will let me use their "special" lacquer from japan if ask them nicely ? i think power supply will cause interference cause its ment for a PC, but i may be able to build a sheild for it Share this post Link to post Share on other sites
kenshinz 0 Report post Posted October 17, 2003 If you're interested in getting a smaller and slimmer power supply (abit smaller than 3/4 the size of normal PSU.. almost 1/2 size), just saw a micro-atx psu rated at 300watts at SLS today. Its retailing at $66. The shop name is M Technic. With that a slim audio deck casing should be possible Share this post Link to post Share on other sites
tropicalrips 0 Report post Posted October 17, 2003 yes, i saw it too i also know the boss of the shop but that power supply breaks down easily i think due to its size, its ment for a micro atx case my problem is not the PSU but the controls of the CD-ROM drive, i think u need some kind of micro-processor to sent commands into the IDE port to control it i hav some info for this from the web, all of it is from ppl building stand-alone MP3 players looks like very "chim" stuff Share this post Link to post Share on other sites
kenshinz 0 Report post Posted October 17, 2003 Haha I remember reading about DIY stand-alone mp3 player decks last time when there were no mp3 players around. Almost everyone was using off the shelf computer parts. And if I didn't remember wrongly, instruction to control the player were passed thru the serial ports. Actually yr cdrom can already do the functions u mentioned above. Stop, play and next, to play previous track, you just have to press down on both buttons on the front bezel. Of course for those of us without 2 buttons on our cdrom... we'll out of luck Another method would be to hunt down one of those old creative cdroms that came with infra and a remote control. The remote control is able to control the cdrom without going thru the PC. Share this post Link to post Share on other sites

tropicalrips 0 Report post Posted October 17, 2003 i thought it would be more fun if i build it myself and not take the easy way out lol i do hav that creative cdrom u talk abt kenshinz, but that too easy, what i wanted was something that can be kind of module form, so if the drive dies i can just change it with another cheap one. the new drives now only abt $30, and i also hav some extra parts laying around like the PSU from the ATX casings after i upgrade one more thing i'm looking into is that most if not all the new drive also hav Digital out, its the connector with only 2 pins, this means if i can get a D/A convertor then the actual quality of the drive inself will not matter Share this post Link to post Share on other sites
lekguan 0 Report post Posted October 17, 2003 err, if you could rest your CD drive on somewhere else more stable, without the noisy PSU fan below vibrating, it should make a difference. Share this post Link to post Share on other sites
tropicalrips 0 Report post Posted October 17, 2003 yep, once everything come together i will build a new case for it, with the PUS on one side and the drive & everything else on another. this current unit was build for my mom who use it in the kitchen when she cooks , then i bought her a mini combo player so thought i try something else with it Share this post Link to post Share on other sites
kenshinz 0 Report post Posted October 17, 2003 Haha I know what you mean, the sense of satisfication u get when u build something yrself is hard to explain. Do keep us update on the progress, if you managed to complete it I would be very interested to learn from you, I also happen to have some surplus of computer parts which could be put to good use.

tropicalrips 0 Report post Posted October 17, 2003 no problem Kenshinz but i'm going to need help most of the things i need don't come off the shelf except for the drive and PSU Share this post Link to post Share on other sites
Mackie 0 Report post Posted October 17, 2003 (edited) one more thing i'm looking into is that most if not all the new drive also hav Digital out, its the connector with only 2 pins, this means if i can get a D/A convertor then the actual quality of the drive inself will not matter I have to differ. Even in a transport-outboard dac setup, the transport does contribute much to the resultant sound. A similar analogy would be a mini-cooper on F1-formula wheels (albeit they don't fit in real life)...................just an analogy afterall.
