You can buy a bare CD mechanism (like the "HITACHI HOP-1000") and drive it yourself.
Is this hard? Yes. But open-source code exists on GitHub from projects like "CD-Reader" and "Nano-CD." You will learn more about digital signal processing in one weekend than a semester of college. cd player diy
One of the easiest: PCM5102 I²S DAC module ($5‑10).
Connect: You can buy a bare CD mechanism (like
Add a simple output buffer (optional, PCM5102 outputs 2.1Vrms directly). Is this hard
If you want complete control (Road 3), you cannot use a donor's servo chip. You must program an Arduino or STM32.
Your DAC board likely has a standard op-amp output (NE5532). This is fine, but boring.
| Part | Suggested model | |------|----------------| | CD mechanism + DSP board | CDM12 or VAM1202 with SAA7824HL | | Microcontroller (for control) | Arduino Nano or ATmega328 | | DAC chip | TDA1543 (simple NOS) or PCM5102 (modern) | | I2S reclocker (optional) | Flip-flop based (e.g., 74HC74) | | Power supply | LM317 for 5V/3.3V, separate analog ±12V |
