Note: Electrical engineering knowledge not necessary for this project, I'm just a mechanical guy with a good understanding of "basic" wiring.
Step 1: Supplies!
- Sonic Impact 5066 T-amp
- Apple PC 5.25 Floppy Drive
- 12V, 2A Power Supply (min 1.5A for substitutes)
- ALPS 50K Log Stereo Potentiometer (Volume)
- 1/4" Volume Knob
- 12VDC, 6A DPDT relay (or even SPST)
- 4x Speaker Terminals
- Stereo RCA Jacks
- Power Cord
- Misc Wiring
Assorted Cutting Implements
Step 2: Modifying the T-Amp (Optional)
I ended up performing the "Input Mods - Version 3"
Prior to attempting to stuff everything into the floppy drive I used a tupperware container as a prototyping enclosure. Things often go wrong when I play with electronics, so I wanted to make sure everything was happy before I started modifying the floppy enclosure. See the pics for a more detailed explanation.
Step 3: Gutting the Floppy Drive
I ended up removing most of the drive's internals, but kept the door lock mechanism intact, as I intended to use the flip of the lock as the ON/OFF switch.
See the pictures for more details on the gutting/cleaning process
