Summertime Heat Wave

The forced ventilation fan isn't working well enough. Let me rephrase- when it works, it works well enough. I think the fan shuts off for some reason- or maybe it is the current switch. In any case, at some point, hot air is no longer being evacuated and then the projector shuts off.

I'm going to do two things- the first is to double-up on the fans to introduce some reliability. $11 fans are amazingly reliable- but two will be better. I've purchased a second fan which I'll put on a Y-bracket so that potentially twice the air will flow. I think I need to get a little creative to make sure one fan doesn't starve the other, perhaps by using the built-in flapper valves.

The second is I want to redesign the hush box. Right now the only intakes are three holes in the bottom of the box. These are hard to filter and probably don't flow enough air into the box. Indeed, I've been running the box with the side open just for that reason. The redesign I want to do is to swiss-cheese and channel the bottom board. I'm thinking slits that run perpendicular to each other on the top and bottom. Kind of like waffle fries (hmm, all this talk of food must be Freud telling me it is time to eat). Yes, waffle fries. Then, those slits will open up to the back of the box where I'll have an easier-to-replace filter- hopefully a standard size. This serves a couple of purposes- ease of replacement, not having projector body directly on filter material, and should direct the intake noise to the back of the room instead of below.
