Projects > 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.
- Electronically-balanced input stage, transformer-balanced output
- Vactrol optocell-based compression stage
- PCB separated into sections based on circuit topology stages, wide pads for easier soldering
- Project board sales discontinued from PCB Grinder (replaced by the MS HOL), but self etch layout version is available here.
