I think we should hack this baby for a laser altimeter.

Yep, I'd like to have a look at it...$2500 is not as bad as DGPS receiver

That would be a great unit except the he cost..$5000+ . I spent $40 on my Bushnel Sport 400, opened it up and found the com port (4 pads) I need to connect o'scope and protocol analyzer to discover commands. Should be able to get 1 Hz updates out. I was encouraged to try this after talking with Lattitude Eng. Group rep at AVUSI show.

Procerus has removed their price but it was only $700.

for a more complete altitude mesuring system you could use a hacked one of these and a ultrasonic range finder for closer to the ground making atonomus landings much safer

For a laser range finder I have used laser pen and a webcam to be accurate to 15cm with range limited by the camera (resolution) and laser (dot visibility - yes night makes it better)
Also created a 3D scanner using a cocktail stirer, laser pen and webcam (£3 cost in total :D).

Unfortunately these were both done using a desktop PC and VB.net and until I can snag a SMD camera that i can easily use I will not be able to begin to "UAV" the setups. I am still trying to mix the hardware setup to produce both range and scans with one laser but the 3D scan requires an altered laser line.
ColinOrd has source code shown and his attempts. Setup is more important as you can skew the scan.
Danko has source code and how to calibrate the setup. Works straight off the bat.

I bought this range finder I opened it up I think the easyest way to hack it is through lcd cable because it's 7 segment its hackable ,
