PCB Grinder Hand of Light

The Hand of Light was designed by Gustav Grinderslev as a simplified take on a solid state optical compressor, using the topology of the UREI LA4 as a starting point. The circuit and construction have been simplified to allow for entry-level use. Case, mounting hardware, power toroid, and output transformer are not included.
