Nokia 6682
With Flash! Here's something from a review:
The camera has an LED flash which you can turn on, off or set to automatic. Even when the flash is turned off, it will light just a bit (perhaps to prevent you from taking surreptitious shots of people). 6x digital zoom helps you get in close; handy given Nokia phones' rather short 4.5mm focal length. To take a photo, just slide open the rear lens cover and the phone will launch the camera application.

Waymarker Ideas
From Jesse:
that's incredible. i feel like i could follow your life all day. what's the time interval?
can we guess which photo shows digital mike at the happiest point in his day? i want emotional association so that i can engage with your life - maybe you can just recommend a viewing soundtrack.

BoohBah
Stephen and I finally got the RF circuit working. We ended up using the old PIC18F452 instead of the 12675 (8 pin, internal clock). I wanted to share an anecdote about why this thing ended up working. We had an LED on the receive pin of the RF receiver so we could see if we were getting data. It would blink when data was coming in. When I program, there's never any partial data loss. If x=5, x will stay five unless I make it 4. It will never turn into 4.99.
This isn't the case with electricity. The RF receiver was receiving information (data) in the form of electricity, and the light was taking some of that electricity to run the debugging 'routine'. Thus the data was corrupted when it made it to the pic chip. Information was being used to light a light instead of to make a branching decision.
The lesson here is to separate your debugging from function and not take shortcuts.
It works!

My Neglected Blog
Which needs to be moved to WordPress so I will pay attention to it. I'm churning along with the WayMarker project. It went over well in class and now I am concentrating on visualization tools (if I end up getting in). Here are some questions that my data visualization tool can answer:
What was I looking at from 2-3pm last Friday?
Show me all the photos I ever took in Central Park.
Show me photos as a stream, one after another. Play back my life.
Play those same photos backwards, the "Momento" effect.
Show me all the photos from last Wednesday as one large collage.
Dennis had the great idea of making them hot links straight to photos, but that means I need to collect more data.
I got a great reaction, from the class and from the guest panel. Very encouraging.
