Music
|

|
|
Hi everybody, my name is Ken Palland and I'm here with say your name.
|
||
|
|
Podrick.
|
||
|
|
Okay, Podrick.
|
||
|
|
What are we doing out here?
|
||
|
|
We are trying to get a egg open.
|
||
|
|
What type of an egg is it?
|
||
|
|
It's a play egg and you have to get it to open.
|
||
|
|
It's from what type of animal?
|
||
|
|
A dinosaur.
|
||
|
|
Ah, a dinosaur egg.
|
||
|
|
What do you have to do?
|
||
|
|
We have to put the egg in the water.
|
||
|
|
Yeah.
|
||
|
|
And then wait for eight days.
|
||
|
|
Eight days?
|
||
|
|
That's a very long time.
|
||
|
|
Yes.
|
||
|
|
We're going to make a film with lots and lots and lots of photos.
|
||
|
|
So we're going to take a photo every minute and then make a big film out of it.
|
||
|
|
Yes.
|
||
|
|
Okay.
|
||
|
|
So what have we got to set up over here?
|
||
|
|
We have got an egg in the water.
|
||
|
|
You know?
|
||
|
|
In a kitchen bowl.
|
||
|
|
Yes, in a kitchen bowl.
|
||
|
|
On some boxes.
|
||
|
|
Yeah.
|
||
|
|
And there's a camera and a light.
|
||
|
|
Okay.
|
||
|
|
It's a USB camera and it goes into what?
|
||
|
|
A raspberry pie.
|
||
|
|
Yes.
|
||
|
|
And the raspberry pie is running a program called FS webcam, which I'll talk more to you more
|
||
|
|
about.
|
||
|
|
Okay.
|
||
|
|
Thanks, Patrick.
|
||
|
|
I'll finish you some.
|
||
|
|
So it's hooked up to the raspberry pie via FS webcam and FS webcam, according to the
|
||
|
|
main page, is a small and simple webcam for Unix.
|
||
|
|
It can capture images from a multiple of different sources and perform SIPM manipulation
|
||
|
|
on the capture image.
|
||
|
|
The image can be saved as one or more PNG or JPEG files.
|
||
|
|
Well, this is the option to go on the background.
|
||
|
|
I want to run it for both of these.
|
||
|
|
So I've just put it into a simple bash loop and I take one shot and then I sleep for a minute
|
||
|
|
again.
|
||
|
|
The command that I'm using is FS webcam dash R to get 640x480 to give the size dash S for
|
||
|
|
15 to skip 15 seconds, dash dash flip H to flip it horizontally.
|
||
|
|
Dash dash JPEG 95 will give you the quality of JPEG and then the rest is just to put some
|
||
|
|
text on it and dash dash save and then the file name.
|
||
|
|
So I'll be taking hopefully a one picture a minute for the next eight days and then I'll
|
||
|
|
just switch those all together, use an FFM bag or some other tool like that and that
|
||
|
|
should give us a video.
|
||
|
|
So which will be available in the show notes for this episode of Works.
