Well its new to me. I can see it now. "Dave, there seems to be an approaching storm. It's time to stop our soccer game and get inside" eBay Link, Datasheet Link
--------
Franklin Lightning Sensor provides early warning indication of lightning
storm activity within a 40km range
- Provides distance estimation to the head of the storm
- Detects both cloud-to-ground and intra-cloud (cloud-to-cloud) ashes
- Intelligent algorithm provides for false disturber rejection
- Programmable detection levels enable threshold setting
for optimal con gurability
- SPI and I2C interface is used for control and register reading
- Automatic antenna tuning
- Supply voltage range 2.4 to 5.5V
- Power-down, listening and active mode

Here is another one for motion detection for up to 20 meters. *eek*
Microwave Doppler Radar Motion Sensor
Datasheet is here: http://www.apollounion.com/en/down.asp?filename=Upload/DownFiles/HB100.pdf
Edit: see post #6 for better one.
UPDATE: Here is another lightning detector that popped up.
eBay Link
The motion detector may be useful though!
parallax item#32213 doppler sensor
Details:
-------
.Operation frequency of 10.525 GHz
.Able to detect motion through walls and windows
.More immune to false triggers than passive infrared motion sensors
.Active-high enable pin with internal pull-up resistor
.Power supply requirements: regulated 5 VDC, 8 mA
.Communication: High (3.9 V) / low (0 V) signal oscillates with motion
.Dimensions: 1.8 x 1.75 x 0.75 in (46 x 45 x 19 mm)
.Operating temp range: +32 to +131 °F (0 to +55 °C)

Im all about simplicity. :}
Update: It seems the comparator board only allows for detection from 8-30 feet. Im not sure there is an application for bots this at that range.
PING))) Ultrasonic Distance Sensor
Example is a current monitor, simple circuit (which is explained in one of DJ's early posts but I can't seem to find it right now) but it's cheaper, easier and neater to throw in one of these breakout boards.
Even if the breakout board, fully wired circuit or whatever is a few bucks more expensive it works out cheaper in the long run with the time and effort saved and you know you are pretty much guaranteed to get something that works right off the bat.

They used one of these as a range finder with an analog input in the First Robotics FRC program a couple of years ago.
The interesting thing is they show the detection patterns for their sensors. They are not cheap but they have both sonar and motion detectors.
I literally laughed when I thought of one of our bots using a couple of these to shoot bubbles out of the ears.

And this one seems like a good LED controller. I've seen them listed on Ebay.

Train smoke sounds good though. Be sure to get one large enough. I've seen them on Ebay but for smaller gauge trains mostly. They make smoke sticks that test cracks/gaps in the home for air leaks but I don't know the proper name for them.

Sometimes there's something that stands out to me as a new idea or a part for sale.
If someone has a new link to add, please add it here.
Peristaltic dosing Head
Muscle sensor
Dust Sensor
Here's another.
Vibration sensor.
It would have to be an extremely sensitive pressure sensor. Have you researched the robot you saw it on? It may list the sensor parts.
Technical Specifications:
-------------------------------
Active area : 5mm Circle x 38mm
Actuation Force: ~0.2N min
Force Sensitivity Range: ~0.2N - 20N
Ideal Operating range (90% or more of resistance change occurs between):10gf ~ 1.0kg (0lbs ~ 2.2lbs)
Force/pressure sensor
Infrared Thermometer
SF02 Laser Range Finder
If I run across anything interesting I'll post it up.
Always looking for more goodies for R2.
I've put this other laser range finder in other threads but I noticed it isnt on this one. Here goes!
Cheaper laser range finder.
Thanks a lot. A appreciate these updates. I check them often.
Here's a cool one using Nitinol AKA Flexinol as a sensor and actuator:
Best,

I imagine these would have to be mounted backwards with the flat side against the inner plastic wall of your bot and use some decals on the outside.

I've seen these forever but I thought I posted them on this thread. I guess not so here it is.
