Wave player using PIC18F4550 microcontroller
Making an audio player (.wav files) using PIC microcontroller is not complicated especially when the MCU has a PWM module. This topic shows how to build an audio player using PIC18F4550 microcontroller where the the file is stored in an SD card with FAT16 or FAT32 file system. In this project I used a wave

Bluetooth-Controlled Guitar FX Amplifier
As part of our final project for ECE 4760: Digital Systems Design Using Microcontrollers, we built a guitar amplifier with remote distortion and digital effects capabilities controlled from a smartphone via bluetooth. Musicians often need to modify the configuration of their amplifiers when performing in concerts. This job is generally delegated to “roadies” who walk

Alchemist Forseti APD15A RC Integrated amplifier
We recently had a customer present this faulty Alchemist Forseti integrated amp for repair – I’d guess this dates from the 1990’s and has been well looked after. It’s a bit of a bruiser as you can see from the extensive heatsinking! Unfortunately it developed a DC fault on the loudspeaker outputs and destroyed the
