Musical Instruments parts lists

BOMwiki maps 50 musical instruments products, each exploded into a recursive bill of materials: 22,378 parts in total, down to individual fasteners and cells. The largest is the pipe organ at 12,901 parts across 8 top-level assemblies; the simplest is the handpan at 28. Across the domain the same components recur: fastener set, coil spring, connector and SMD passive (R/C/L) appear in most of these machines, and each is a single shared page here, so a correction to one fixes every product that uses it. Open any product for its parts diagram, the function of each part, and the full bill of materials.
