DESCRIPTION

This project is intended for people who have never stuffed and soldered a PCB before.

It was created by the Audio Builders Workshop, which is part of the Boston chapter of the Audio Engineering Society.  We offer this as a full kit with parts with extensive directions at various audio related events in the Boston area.

We hope other groups will use this project (or copy and modify it) for organizing their own public events to teach others basic electronics assembly skills.

TECHNICAL DETAILS / COMPONENTS

Based on the classic 555 timer circuit, this metronome includes a LED, speaker, and line level outputs.

More details can be found on the schematic.

The design was done in Altium CircuitStudio.
