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.

Dual-channel 1.8T knock-sensor signal conditioner using an ATtiny1616, matched differential analog front ends, RPM-adaptive processing, and a protected 0.5–4.5 V ECU output.

Dual-channel 1.8T knock-sensor signal conditioner powered from the MaxxECU 5 V sensor supply, producing a protected 0.5–4.5 V analog knock-severity output with RPM compensation.
