16  Using Arduino / Programming Questions / Arduino web server and PHP on: April 12, 2012, 09:10:26 pm
Just a quick question,

Has anyone ever managed to get a stand-alone Arduino web server to serve up full PHP pages, or HTML pages that include PHP code.

example:
Code:
<html>
<head></head>
<body>
<?php  
echo "<h1>Hello World</h1>";
?>

<p>That was PHP saying Hello World.</p>
</body>
</html>
17  Using Arduino / Project Guidance / Re: Altering files on Arduino+Ethernet web server on: April 08, 2012, 11:29:23 am
I suppose this would be an interesting challenge to tackle.
I have this concept idea where you have a page with a few text and button inputs where a user types out the new file name with it's contents.
I've attached a basic example pic below.

It does seem quite simple though, similar to data logging to SD cards although different in that the user writes the variables for the file name and its contents through an Arduino-hoseted web page.
18  Using Arduino / Project Guidance / Altering files on Arduino+Ethernet web server on: April 06, 2012, 10:02:08 pm
Quite a while ago I built myself a nifty little Arduino ethernet web server [Link] and one of it's downsides was that in order to update the web server's content, hosted on it's SD card, one had to remove the card, update desired files, and manually restart the server.

So I was wondering if it was at all possible to modify the files on the SD card of an active Arduino web server remotely via a hidden web page.
Any info would be appreciated.

Did security check the device?

Nope. They didn't even hold it in or run it back through the x-ray.  smiley-mr-green

Thanks for the replies everyone!  smiley-mr-green

On my late trip to New York, I spent some time capturing over 6 full hours of time lapse footage. Ending up with a total of 5,563 images, all of which were taken by this awesome little device.
Have a look at the final result.

And for a short, unedited time lapse segment from (almost) street level of the south side of times square.

A sudden and late summer trip to New York was just planned from here in Florida with my parents.

I would like to bring my latest creation, an intervalometer for my camera for taking time lapses. However I am concerned with the fact that it might look "suspicious" to the TSA.
I would prefer to take it with me on carry-on, with the rest of my camera gear. I already know that I should remove the 2 AA batteries from it and I suppose from the rest the carry-on as well.

Another reason I would like to take it with my carry-on as oppose to the check-in baggage is so I can explain, if that would be possible, what it is rather then have it removed permanently altogether after checked-baggage is checked in.

I wish I had the stickers from the Maker's Notebook for this thing.

Interesting ideas everyone,

I started this topic just after it came up in an Adafruit chat, I see that some of you also heard it there too.

I didn't mean to have an Arduino on a rocket or space ship, I meant it as a logged high (very high) altitude weather balloon trip. I personally like the idea of a radiation detector or geiger counter as suggested by CrossRoads.

...what would it be?

I almost forgot, you people want a schematic don't you.
Here you go. (In main post too.)

@Kaouthia,
Another thing that could be lessoning this flickering in my case is the fact that I was using long espousers of 8 seconds for the night shots. This would average out the initial wrong-doing of the aperture.
26  Community / Exhibition / Gallery / Re: Binary Intervalometer on: July 05, 2011, 05:11:37 pm
What aperture were you at?

In the first segment of the video I was at f/3.5 at 18mm
The second segment was at f/5.6 at 200mm
The third segment was at f/5.0 at 65mm
And the final sunset segment was at f/22 at 32mm

I have never experienced flickering from the aperture as is settles in place, although I can see why this would happen. I don't think I have ever experienced this is because my camera, the D3100, being entry level (and becoming a little under-featured for me) has a slow burst rate of 3 frames per second. Since the entire mechanism is considerably slow this would allow some time for the aperture blades to settle before the sensor gets exposed.

If your camera has a quiet mode, I suggest that you try taking time lapses with that and see if the flickering improves. This may include a delay between closing the aperture and opining the shutter.

What body & lens are you using?  The lack of any aperture flicker is rather impressive.

Nikon D3100 with NIKKOR 18-200mm f/3.5-5.6G ED VR II

The flickering is prevented by putting every variable on the camera to manual. This includes white balance, shutter speed, aperture, ISO, and focus.

The sparse white-ish flashes that may have been seen were due to me wielding a flashlight while being rather board, and to indicate a manual change in exposure for later editing in post.

Any example photos you shot with this compact device?

Here is what I got yesterday on the 4th.

I'm not super satisfied with this specific time lapse but I hope to get some better materiel later this summer.
This was just a test for the intervalometer; it works perfectly.

There's plenty of other manufacturers out there.  The Yongnuo ones are dirt cheap and offer, I think, better options than the Nikon/Canon ones.

I guess you could say I'm a stickler for the name brand, non-third-party products.

Besides, where are you going to find an open source intervalometer that utilises binary and is built inside an Altoids tin?  smiley-mr-green

(There fairly expensive)
They're not, but very nice job. smiley

Eh, for the name-brand ones from Nikon or Cannon, and considering how simple they are, ~$150 isn't very agreeable.
