Hello guys. I am Peter from Build A Boeing. How are you all doing?
The cockpit right now is - as always - one big mess in this rebuild fase.
Nothing has been connected yet. But I've tried to start making a cockpit shell this SimuJabs drawing
And you might be able to see the back frame here - the back wall.
And upper window frame.
Then I started making the lower window frame that should go here.
And there were just too many different angles too many measurements that I couldn't figure out.
so I kind of gave up on that part...
Partly because I got these two projectors!
And I've now started my 180 degrees curved screen project
which is pretty cool.
I'm just testing things right now.
So I'm using bed sheets as screen right now that's why it's a bit wobbly
I've just quickly mounted some thing - some fabric - to project the picture on
The frame itself is made out of wood
and these sections, the two sections here - or two pieces of wood - they cut each at 7,5 degrees.
Put together that is 15 for this one. 7,5 and 7,5.
15 and 15 that makes 30 degrees for a section
And for each 30 degrees I have vertical support - there
That means from the middle there I have 1, 2, 3. Then I have 90 degrees to each side
When mounting these. The way I did it - because I have two - is that I here
in the front put a piece of yellow string and it goes over here to the side
it's like five centimeters away from the wall so that I have room for this support here.
But that yellow line there, you can see it goes - maybe you are able to
see it goes - over there as well. Yes. That is what I call the "flat screen".
That is the areas your projector should be able to fill out.
It forms a "V" as you can see. Then you have an opposite "V" which goes
from the corner of the room and over here to the middle and then back there
and on that line it's where your projector should be mounted.
Then you can use the distance calculator online and you can from that cross right
there calculate how many centimeters back your rejection should be mounted
and that is for me right there.
At least I thought so.
On a normal short throw projector that will beam the top part of the picture in horizontal matter.
But because I have ultra short throw they're working it in a different way with some mirrors
which means because they're beaming downwards
the picture on a curved screen actually goes like this. So it kind of bends down.
That means I have to had to pull them back a bit, to have the picture going from up there and then
bent down here and then back up. Trial and error.
Luckily, I made these two rails here and mounted the projectors onto them.
But then I had to move them back so I came up with a new idea on how to mount these
And it actually works quite good.
You need one rail here and then in the back here one as well.
And then the projectors are mounted on pieces of wood.
But the these two - going that way - are not fasted in a way I can move them back and forth
which means I can move the projectors around until the picture is perfect.
But as there's nothing is going to move the projectors later on they might as well
just lay there on top of these two rails. That means I can actually mount
them unto a nice wooden ceiling like this with just one screw there, one there
and two screws down here. Four screws in total.
My wife like that I've not totally demolished the ceiling
What else... I have a piece of wire hanging
down here this yellow piece here. It goes from the middle up here and where that
is mounded I have the same distance to each side and to the front.
So that kind of marks the viewpoint of where my head should be in the cockpit so that I have
here I have a side view to each side and they saw also the middle of the cockpit.
That means later on I can move my base around so that the cockpit is perfectly
placed in this half circle. So it needs to go forward a bit and then a bit to the side I reckon.
So this is my first attempt at a curved screen.
Next up - in the next video - I will try to start prepar3D and start wrapping the
picture see how that goes... And hopefully within a few weeks I will be able to
have my first flight.
I'm Peter from Build A Boeing You guys take care
Bye bye.
