The Blinky Amp is a custom audio amplifier built from scratch, designed with visual feedback through LED indicators. It features:

  • A 10-LED volume meter reacting to audio levels
  • A pulsing LED power indicator controlled by a 555 timer
  • A custom plexiglass enclosure showcasing the components

The amplifier circuit is based on a TDA2003 IC, which was commonly used in simple audio applications. Though some components were hard to source, the design was fully through-hole, making assembly straightforward.

This project was an early exploration into hardware design and interactive visualization, blending electronics with aesthetic functionality.
