The window glass is high transparency reduced IR glass from endmund optics. but you may almost use everything. The human body is Glued Up Plywood sanded nice an fine then stained and lacquered. To secure a good complete you'll want to sand with high-quality grit in between Every single coat, three or 4 coats plus your fantastic. Now my Projector is Much Significantly quieter. :-)
That, not surprisingly is because of 3D’s need to have for brighter projectors. The HC8350 is an older, LCD based mostly projector that’s strictly second. In addition to the Acer H6500, the loudest, and also the HC8350, by spec, all the rest declare to become inside a modest 3 db of one another.
Yes, I have already been out for awhile do to loved ones. Effectively, I'm back and we are pretty occupied developing projector hushboxes. Sorry for people of you who couldn't get in contact with me throughout that sad time in my lifetime!

I visited them a long time in the past as a small start out-up and wrote about them. That they had a patent with a microcomputer-based technique that relied on sampling the supply frequency of noise (like a spinning supporter rotor), then building the cancellation anti-noise inside of that narrow band.
As well as would I have to have a certain quantity of free Room behind the box exactly where the projectors lover exhaust is?
Could somebody indicate any significant design flaws, or advocate something that could possibly do the job improved or merely any typical guidance on my initial query.
