    I'm reasonably sure he'll have SEVERAL home-built projectors on display for SELEM this year, Chris! Remember that the ENTIRE cafeteria will be open for people to display their home-made projects, whether they're laser-related or not. So, yeah, I expect we'll see lots of cool stuff in there.

    With regard to making this projector even smaller, about the only thing I can think of would be to remove the power supply and make it external. Something like a laptop brick PSU... But that's kinda cheating in my book.

    Yeah, Chris, Adam is correct. As of now, I expect to bring this ultra-portable projector, the dual RGB/Glow-in-the-dark projector, my Saturn 1b graphics projector and a couple others. How about you? Are you bringing the plane or the race car??

    Yup, already done. Specifically, it runs off a 12V Lion battery with built in charger. I haven't run it from full charge all the way down, so I don't know how long it can run, but I expect its an hour or two based on the lack of discharge the battery displayed during testing. It would pair well with a laptop and a USB powered DAC.

    I plan to fly if the weather will let me otherwise I will drive "the Race Car" as you put it. Lol
    My dad is driving to Myrtle Beach and plans to come to SELEM for the final 2 days. I will fly to Myrtle Beach and pick him up Friday and drop him off Sunday morning.

    I tried using a 266nm laser for projection but could not find mirrors that worked. Would have been cool like a ghost.
