    Default Rainy day project - camera barndoor



    It rained pretty much all week in CA which is actually great. I had been thinking about a barndoor for my camera and I had an Arduino and some steppers lying around so here it is. Not quite finished yet - I need to add a battery pack, the pics you see is the working barndoor powered by a USB slot - and some wire cleanup/hiding. But it's nice to see. It is a very simple design with the motor driving a short screw directly. Because of the direct drive simplicity the screw length is necessarily small (little toerlance) but long enough for almost an hour I think, which is much more than what I need. Too bad I had to use an Arduino Mega, which is really overkill. I may get a smaller one some day and replace it.

    Nice work. That is an impressive looking barn door mount.
