Datalogging first stab

For the first pass, I used Toms code - http://www.tigoe.net/pcomp/code/archives/php/000713.shtml - for the PIC, Processing and PHP. I used a potentiometer on the board.

Issue: datalog.txt was not write-enabled.
Solution: change to write-enabled by telnet on SSH with chmod 666

[rb1551@itp ~]$ telnet itp.nyu.edu 80
[rb1551@itp ~]$ ls\

public_html
[rb1551@itp ~]$ cd public_html
[rb1551@itp public_html]$ ls
flash2 index.html logger.php datalog.txt
[rb1551@itp public_html]$ chmod 666 datalog.txt

Now it works!
http://itp.nyu.edu/~rb1551/datalog.txt

Issue: time stamp wrong.
Is this an issue on the server? Is it possible to fix with php code?

Datalog.txt log:

2006-02-25 06:02:51 0
2006-02-25 06:02:55 0

This data came up between 6:07 and 6:09. Processing output looks like this:

Wrote 2006-02-25 06:02:43 0
to file datalog.txt

However, it does say
HTTP/1.1 200 OK
Date: Sat, 25 Feb 2006 23:09:34 GMT which is the correct time in Greenwich, but translated incorrectly here

Looking at php.net, I got it to display military time, but its still incorrect. It does show the 4 to 5 second intervals, but the incorrect minutes.

Adding ,$timestamp to the php, excitingly enough, makes it 9pm on December 31st, 1969.
I removed that, and tried writing date_default_timezone_set('GMT');, but that stopped the writing altogether. As did trying to include a time() function.

Kate and Zach are having the same problem. Kate has emailed Tom

Oh wait it seems to be working now!

Now what Id like to do is use a flex sensor as my analog sensor and record the data on that while simultaneously video taping the flex action with a clock in the background of the video that matches exactly the timestamp on the data. It seems like a good way to compare data with a visual reference.

OK, so the next step I'd like to take is to use a flex sensor as the analog input, and videotape the flexing with a clock going on the tape. It seems like a good way to compare the output data with a good visual reference.

I'm looking forward to getting more in-depth with all things sensors and pcomp. I found myself [[http://www.overainslie.org/rbray/itp/table/updates.html | getting really familiar with the qprox]] in December when the semester ended, and I looked around to see all the other sensors I hadn't had a chance to really get to know. I've got some specific projects and applications in mind that use touch, proximity, motion, but I'm open to exploring more. I recently saw a site somewhere that talks about a sensor that reads C02 levels and was used in a project that drew grass on the wall at heights related to the number of people in the room, breathing out. I love it - a really interesting use for a simple sensor. (does anyone have that link?)

The site with my [[http://www.overainslie.org/rbray/itp/sensors/ | Sensor Workshop updates is here]].
