PComp catchup. It's been a bit since I blogged anything here - Eddie, Chris and I are knee deep in our final project (due Dec. 12th) building a lo-fi digital camera. We have all been posting primarily to the Development Wiki. I've been doing some sketched tonight that will help clarify things in my head. So far, I think the main issues are going to be:
Programming! The processing for this application is going to be very complex. It's one thing to get brightness values to come across into the program and display on screen, but it's another thing to freeze those values on screen as one moves through the image. Also, since the values we have been getting from the photocells fluctuate quite a bit, we'll need to incorporate some averaging in there.
Frame construction Building the camera cell patch navigation system is going to be somewhat difficult.. at least to fine tune.
Multiplexors Though I have faith that we can figure them out, none of us have worked with multiplexors before. We have 64 analog ins, so they are definitely necessary. Tom went over them in class last week, which was helpful in that it gave us a foundation to work from.
Light focus Will we need a lens? remains to be seen.
In any case, we're pretty excited and things are definitely coming along on the project. I'll post my sketches when I get the chance.
We don't have class this week, but next Wednesday we'll be going over the readings which I haven't posted about on here. I'll need to pull together my responses to those, and put up my thoughts in the next day or so as well. A lot going on!

Observation Assignment revisited
Sunday, November 11, 2007
Yesterday I had to go to the Mariott Marquis in midtown to pick something up from the American Express desk. The whole hotel was equipped with smart elevators, like the ones I had observed in the office building earlier in the semester. I had to go the eight floor - it took less than five seconds for an elevator to be assigned to me. Since I was familiar enough with the process, I was able to navigate through fairly easily. However, the general sense of the crowd on the ground floor was at the very least dissatisfaction, and at the worst, chaos. It really brought to light that there are many different kinds of users of technology. For me to adapt to the new system when I take an elevator to the 37th floor dozens of times a week is a little different from a tourist from the suburbs, who may rarely ride an elevator as part of his day-to-day routine, adapting to such a system.
