: : I WANT TO MAKE VCD/MP3/ACD PLAYER ALL BY MYSELF. I WANT BRIEF NOTES OF HOW VCD/MP3/ACD PLAYER WORKS ? : Basically this kind of stand alone player consists of following part: : 1. CD reading hardware (typically nowadays a computer CD-ROM drive mechanics and alectronics) : 2. Controllign microcontroller (reads user controls, controls displays, sends commands to Cd drive, rreads data from drive and sends it to decoder circuitry) : 3. Signal decoding circuitry that takes in the compressed digital data and outputs analogue signal or digital uncompressed data signal (MP3 decoder IC, MPEG decoder IC etc.) : 4. User interface (buttons, display, etc.) : 5. Power supply : 6. Case where everything is put in : You can find plans to build MP3 players at : http://www.epanorama.net/links/project_pc.html#pc_mp3player : I do not have any plans for VCD player.
