    It sounds insane, but the array that drives it is functionally not that different from the array that individually causes LCD crystals to shift.

    I have DLP parts sitting around because they’re cool.

    Edit pics:

    Edit2 explanation: A white light is focused onto the DLP mirror chip through a kind of kaleidoscopic lens, I’ll spare you the details on that. The individual microscopic mirrors are aligned with charges to bounce light. The mirror array pulses synced frames through the spinning color wheel to create a composite image. It’s a fucking insane idea that barely works… and people like me, with low persistence of vision, are not fooled very well and we see color banding and all kinds of weird artifacting lol

      Woah that color wheel… You can see the cyan, magenta, yellow light reflecting but red, green, blue light passing through to the table, respectively. Such a great example of complementary primaries

        I’m so happy you noticed, the colors cannot be reproduced in a digital photo, when it shines in the sun it’s so beautiful!
