Budda Chakra Compressor

Here's an optical compressor I came across on FSB and hadn't seen a layout of it before. There's some question as to whether the schematic is accurate on FSB, so build with care. The original uses a rectifier array component, but I've broken that down into 4 discrete diodes (1N4148, 1N4001, etc.) since I figure more people will have those on hand than the rectifier component. Should fit nicely in a 1590B. Schematic and more info on FSB.
