I’m an optomechanical engineer and I’m sorry. I’m not impressed. In a Michelson, the single most important requirement is that the optical path lengths of the two arms do not drift with respect to each other, either in length or angle. Having that path length determined by a fused deposition polymer is about the LAST choice I would make. I have a suggestion. Fused quartz rods are relatively cheap. Buy some 6mm rods and a thin diamond blade to cut them to size. Use the 3D printer to make plate-like parts, ‘replicating’ a cage structure. The polymer parts should be used only for components PERPENDICULAR to the optical path. You could even experiment with using embedded rods to stabilize the plates in various directions. So much of hobbyist activity amounts to a kind of adult coloring or copying. Rather, at your own level, try to be a scientist.
I have found that my best designs, few and far between, enter a period where they get simpler as they are completed. And my worst or failed designs keep getting more complex as I go on.
"Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius — and a lot of courage to move in the opposite direction."
Notice that this makes great sense macroeconomically. So you are warned: you will get the healthcare you demand, in addition to that which you pay for. And a certain amount of gaming of the healthcare system is always required. One further note. The more serious your condition the more likely for (1) doctor mistakes and oversights (2) omitted treatments. This requires vigilance and manual correction by you.
This is a hugely important point. The de Broglie wavelength of the photon is hundreds to thousands of nm. There is no possibility of VLSI scale-up, a point conveniently omitted in hundreds of decks and at least $1B in investment. Photonic techniques will remain essentially a part of the analog pallette in system design.
Not always true. My landlord recently had a contractor call me. I did my usual "pick up and don't say anything" routine for unrecognized numbers, and the contractor silently hung up and never called back. Thankfully my roommate actually answered the call, but pick-up-shut-up prevents legit people from leaving voicemails and sometimes prevents legit people from reaching you entirely.
Personally, I would utter a confused "hello?" if I was calling somone, the ringing stopped, and no one said anything, but I guess not everyone would.
I could easily see someone like a contractor calling from the road or otherwise not paying full attention to their phone. They likely never realized you answered and needed the "hello" to refocus their attention.
As with 'craftkiller, I've noticed that I do need to make some kind of noise. I've settled on subtle light coughs or grunts (nothing anyone would think twice about, but which will definitely trigger a "oh this is a human!"). I figure it might still fool some percentage of automated systems which detect whether a human (and which human) is actually there or not based on automated transcription.
