    Thanks for arranging this Andrew!

    Does anyone know if the waveplate in these is really a quarter waveplate, changing circular polarization to linear and vice-versa

    I just wonder since Leslie mentioned:

    "M: Wave Plate. This would be expected to be a Quarter Wave Plate (QWP) based on similar optics in other pickups, but its behavior is somewhat strange compared to a known QWP"

    Don't know about the waveplate, but the final order list has been posted here.

    Update: The laser pickups have arrived!
    All of the components are here, so (Priority!) shipments will begin tomorrow.

    Thank you all who participated for making this possible!

    here's a photo of a compact driver board assembly (it was requested to be built as compact as possible):



    the heatsink for the regulator isn't necessary for the violet lasers up to a power supply of 12V.

    As these are received and built, hopefully others will post their less cramped examples
