Garage Monitor 3k
Need to know if the garage door is open? Need to know if you pulled in far enough for the door to close without hitting your bike? Need to know all this with web access... I present the garage monitor 3000.
When the car reaches the right spot, the LED turns from green to red.
This is a work in progress, this is just version 1.0, I think it will go through a few changes to make it even better.

Parts
Wire
1 Mercury switch
1 220 ohm Resistor
1 10k ohm resistor
2 x 1k ohm resistor
1 Red LED
1 Green LED
1 Parallax Internet Kit (PINK from parallax www.parallax.com)
1 BS2 Micro Controller (from parallax www.parallax.com)
1 PIR Motion Detectorr (from parallax www.parallax.com)
1 ds1620 temperature chip.

I had no network drops in my garage, which I obviously had to fix, so I bought a linksys WET11 off of ebay for $20.

Bread Board It Out.
So I obviously need too make a wiring diagram...
But you can't go wrong if you follow the examples in the PDFs that come with all of the parallax parts.
The wiring for the switch comes from the PDF Whats a micro controller
The wiring for the PIR comes from the PIR Documentation PDF
The Wiring for the DS1620 comes from the PDF Applied Sensors.
The wiring for the PINK from the PINK PDF
P0 - for the pir
P1 - Mercury switch
P5 - 1620
P6 - 1620
P7- 1620
p12 - For PINK
P13 - For PINK
P14 - Green LED
P15 - Red LED

Now That It Works on Your Breadboard...
You should probably program the bs2, here is the code. Most of this code is closely based on examples in the various PDF available on the parallax site. You pay more for the BS2, but the documentation is great.

Close the Field of View for the PIR
So the PIR has a crazy wide field of view, I closed that down by using a 5" piece of poster tube, I got this idea from a post on the parallax forums, they used a wider tube, but it was still a really slick Idea.
I secured the PIR to the tube by putting a hole in the cap of the tube and hot glueing it.
I connected this pack to the breadboard by using phone cord, I had tons of it laying around. I found a 3 prong connector on an old CPU fan that I used as a plug for the PIR.

Secure to the Wall
I secured this to the wall right where my car needs to stop to clear the door. I used a zip tie and a staple gun.
Freddie Mercury
I attached a mercury switch to the bottom of my garage door, using phone cord again because I had so much of it...
Put It All Together
I attached all of this to a piece of sintra just to keep it clean. I need to cut a shorter ethernet cable but I don't have a crimper at home.
Next steps...
Does it really need to be on all the time? Maybe I should have it power on when the garage door opens and the light turns on. That way I could have it update a table in a database with the last status? I guess having it run all the time is just kind of wasting electricity...
Maybe I should put it in a project box!
