Trying to figure out details so I can move toward building this.
I’m hoping to draw up a plan for it soon, but the rough idea would be as shallow a box as possible top to bottom, with an exhaust fan in either side in front. Looking at a dual set of ac infinity 120mm fans that would output about 20CFM each on their lowest speed, which according to Mike’s info is spot on for exhaust.
A few questions...
If a cut grills/openings on the sides of the box by the back, can I get away with just using fans by the exhaust in front, on the assumption that the projector’s intake fans will pull in what they need? To please the wife I might try and fashion some sort of decorative grate over the intake area, like a small version of what you’d see on a nice HVAC air register.
These were the fans I was looking at: https://www.amazon.com/AC-Infinity-C..._dp&th=1&psc=1
Mike, in terms of sealing off front to back with foam, I get why that’s necessary, but what kind of foam would you suggest for doing the job without affecting the finish of the projector? Do you mean sealant construction foam (something in the vein of expanding fire foam or caulk) or were you thinking more like soft foam like the type that’s sometimes used in packaging?
How small should the port hole be in front for the lens? I actually love the look of the projector, so in an ideal world I’d cut the hole wide enough to see the full gold trim circle around the lens, but obviously not at the expense of lots of noise getting out. The e-shift buzz can be a frustration on top of fan noise, so if that’s emerging from near the lens/sensor area I’d imagine I should just make the hole as small as possible and hide the trim?
Also, do you guys recommend something akin to mojo’s method where you use foam or foam board at an angle on either side of the lens to limit sound/air escaping through the lens opening?
Finally, I assume for remote functionality you just mount an IR blaster inside?
Happy Holidays guys!
