Open the CD-ROM case. Locate the button PCB. Solder wires to:

Connect these wires to Arduino pins (with 10k pull-ups). The Arduino then simulates button presses by pulling pins LOW for 50ms.

Use modular commercial boards connected via wire wraps.

For this article, we will focus on Road 1—The "Salvage & Upgrade" method—because it yields the best results for the lowest cost.

You don't need a 3D printer or a CNC mill. You need a screwdriver and a thrift store.

| Component | Spec / Example | Approx. Cost | |-----------|----------------|---------------| | IDE CD-ROM Drive | Any old LG, Samsung, or Lite-On (must have play buttons on front) | $5-10 (used) | | Arduino Nano/Uno | Any 5V logic board | $6 | | 12V Power Supply | 2A or more (e.g., old laptop charger) | $10 | | 5V Regulator | LM7805 or DC-DC buck converter | $2 | | RCA Jacks (Red/White) | For line output | $2 | | 40-pin IDE Cable | Old ribbon cable | $1 | | 6x Momentary Buttons | Play, Stop, Prev, Next, Eject, Open Tray | $3 | | Resistors | 10kΩ (x6 – pull-ups) | $1 | | Enclosure | Wood, acrylic, or 3D-printed box | $10 | | 3.5mm Stereo Jack | Optional headphone out | $1 |
