Mini Light Shield

This is a light shield designed for our optical phaser projects, based on the types used in the original Univox Uni-Vibe and Mu-tron Phasor II.
The Uni-Vibe enclosed the lamp and LDRs in a reflective sheet-metal box that dispersed the light internally so that all four LDRs were evenly exposed. It also blocked most outside light so the effect would still work when the enclosure lid was removed for service.
The Phasor II used a round metal cap around a plastic base to enclose the LED and LDRs. It was signficantly smaller than the Uni-Vibe solution but the effect was the same.
For our original Straylight project, we designed a solution that uses interlocking PCBs to build a box with a reflective interior that can be soldered in place, which closely replicates the functionality of the sheet-metal box of the Uni-Vibe.
For the Straylight Mini and Hexatron (Phasor II), we used a double-tiered PCB layout so they could fit in a compact 125B enclosure. Accordingly, the light shield was redesigned so that it can fit between the two PCBs, with the PCB itself acting as the removable lid. The mini light shield comes in a single panel with four sub-PCBs that can be easily separated.
