This project aims to build an Audio Amplifier using the TDA2822 IC. The TDA2822 is a commonly used dual-channel audio amplifier that can deliver high power output. The amplifier will be designed to drive two speakers with volume control and the audio input can be directly provided through an audio jack. This project is inspired by my class Analogue and Digital electronics.

ChargeGuard Gateway - PCB layout review status: schematic power tree review is clean; remaining work is PCB-layout-only cleanup. Current DRC inventory: 136 Overlapping Copper, 56 Floating Copper, 88 Airwires, 0 Missing Footprints, 0 Invalid Layer, 0 Important Overrides. Priority 1: protected input and power-path regions around VIN_PROTECTED, VIN_FILTERED, +5V_MAIN, +3V3_MAIN because these can block reliable routing and copper pours. Manual PCB editor tasks: remove/reshape overlapping copper, reconnect broken traces or redraw routes causing airwires, delete stranded copper islands, inspect ambiguous pad-to-trace shorts around power devices and connectors. Agent-preparable tasks: maintain issue inventory, classify nets and priorities, preserve stackup/documentation, define DRC recheck loop, and guide Auto-Layout sequencing after manual copper cleanup. Recheck loop: fix one issue class or one critical region at a time, rerun DRC, confirm counts decrease, then move to next batch until airwires/floating copper/overlaps are zero. Completion checklist: 1) clear power-path overlaps, 2) remove floating copper islands, 3) close all airwires, 4) rerun DRC after each batch, 5) confirm clean layout before manufacturing export.

I am trying to design a simpler solution to integrating a Bluetooth board into an iPod classic 5th gen model. Since current aftermarket mods that add Bluetooth require micro-soldering several thin wires to the iPod board, creating a central board that offers enough room to solder flex cables, reminiscent of modern game console mods, is a cleaner and better solution for the future. This project aims at creating the central Bluetooth board for this purpose, the flex cables will be designed and measured out at a later date.
