Hey gruppe,
Here's my statement and my preliminary LED research. As far as the LED research goes, I wanted to give you guys an idea of where I was going. More to come on Thursday. Are we skyping? Remember, Sam, Monica, and I will be reviewing our preliminary research and statements together tomorrow (Wednesday) afternoon. We will review each others' work and make sure that each person is focusing on the correct stuff. As far as the statement goes, we will combine, revise, and publish here on the blog. Germans: please give us your feedback and edits as well. We want to make sure that everybody has a say in the mission statement so that we can continue to have focused product development. Good work, guys!
Talk to you soon!
Thanks,
Rob

Statement:
The primary goal of our "pole" lighting system is to encourage pedestrians to manage their crossing time within an intersection by giving them time elapse information. This information will allow them guage their ability to cross the street before cars invade their zebra stripes. Conversely, this system discourages the pedestrian from taking the risk of crossing the street during cars' right of way by counting down the time until he can cross safely. The pole's secondary function is to alert pedestrians of partial right of way during cars' turning rights.

LED Research:

The ideal system: Waterproof, flexible LEDS. Cons: not bright enough, might not have the colors we want.

A VERY bright option. Can we get this in strip form? Is it too bright? Cons: It's by GE.

I think this is the level of brightness we want. But the structure is way too thick.

PS--sorry about the raw links. I don't know why it won't let me embed them tonight.

things to consider:
-brightness
-lifespan (comparative...context?)
-energy efficiency (sustainable?)
