I talked to the Finite Element guys. They confirmed that the number of grids is close to the number of pixels if the pixels are sharing corners like an FE model does. There is no clean equation for a complex shape. it depends on the number and length of free edges to interior corners. Not real impor...

3x3 in my previous post was 3x3 PIXELS. clearly not obvious unless you lived inside my brain. I hear you on the assembly time and hassle on the playa if all the pixels are separate. It will be a judgement call by managment (sputnik) considering the pros and cons. Maybe a mix of the ideas - For the r...

Here is another concept for putting this thing together. The assumption is that the picture will get full of dust no matter what we do so the attachment scheme should not take that into account. keeping it "clean" becomes a separate issue. So now the requirements are keeping it attached to the playa...

Good point, but I'm not too worried about us exceeding any space requirements. It does mean that the image would stretch out in that direction and we should take that into account. we missed each other on a couple of points- it's the cost of doing this in a forum which is fine since we all get to s...

woke up with thoughts about this project. if 8 inches is a safe distance then we might use that to not only vent the picture but also to minimize the pixles needed. if we make each pixel 36 inches then that means 5 gaps eliminates one row or column. 36 inches allows for 2 inch wide seams or channels...

I've mentioned to Sputnik before that I worry about the thing staying put. I will put some effort to collect information regarding the structure of the picture so it stays in "one piece" in terms of what the camera will see. Sputnik, do you have a guess on the size gaps that will be tolerable betwee...
