Gosh, that animated nacelle effect is spectacular and I think Smithsonian achieved this optic rendering with little or no mechanical equipment involved.
The reason I’m writing is that in thinking through the problem of undesirable laser light reflection happening to the saucer section underside of my 1:650 Enterprise model build, and that there’s a way to defeat this. It’s just an undesirable side-effect of using lasers and it may prove to be extremely difficult to mitigate and would welcome your thoughts on this.
There are a couple of approaches that I suspect could reduce lateral laser light reflection to the saucer’s underside when firing the phasers. One is to add highly reflective silver or chrome to a tube of yet unknown length that affixes to the front-end of the diode lens. I don’t know what that will do either – if anything – until I tinker around with it some and see what happens.
The other idea is to introduce a laser light absorbing dope to the paint used for the saucer’s underside, but it’s really difficult to pin-down beforehand how well that would work. I don’t know if you’ve tried tackling this problem before but I’m at the point where I can brainstorm and try different things to see how they work since I’m about to bench-test the laser diode assembly in a few days and make and/or incorporate those kinds of adjustments.
