design student in need of help with a lighting project -- will pay!

[jason]

I am a design student at Pratt Institute in Brooklyn. I have a
project/prototype due this Thursday and wanted to see if this is
something you (or someone you know) could be able to help me out with.
It doesn't have to look great, just work. I can design the housing (if
necessary) around whatever the outcome is


Essentially, this would be a motion detector hack.

The parameters around what I need to be built:
- an occupancy sensor that screws into and is powered by an existing
medium-base light socket -- the bulb then screws into the sensor
- if the sensor doesn't detect someone, the light runs at 80% of its
maximum output
- when the sensor detects someone, the light output increases to full
capacity (i would like this to be a smooth transition/fade, instead of
on/off)
- 15-seconds (adjustable if possible) after area is unoccupied, the
light decreases back to 20%

If you need a visual representation, please let me know. I will be more
than happy to pay for parts and materials, as well as a reasonable rate
for labor. Or if you would like to barter, I am an award-winning
graphic/web designer and can help you out in that area.

Thanks in advance!

Boy do you have a lot to learn...

How big is the area you wish to monitor?

Well, for this prototype it could be as little as 25' in diameter.
Again, thanks for the response.

You could do this by hacking into a yard sensor. You might even be able
to simply use the sensor; just have two light sources, one at 20%
intensity, and the other controlled by the yard sensor.

Unfortunately, the two problems you will have is A) setting the thing to
turn off in 15 seconds, and B) the fadein/fadeout.

A microcontroller circuit to fade in and out the light when it's enabled
is simple, but you won't even be able to get parts by thursday...
