What is a rangefinder capable of finding the range of something 50 feet away that is axon capable?

Expensive.

Doesn't have to be - you could use a 50 foot long stick with a switch at the end, and a linear encoder switch to figure out how much of the stick was extended before hitting an object. (This would be more like a tape measure than a rangefinder... but wtv.)

What kind of sensors do they use in those "follow behind" cruise control systems you see in cars?

would there be a way to hack the golf laser range finders and feed the info into an axon?

Hi,
would there be a way to hack the golf laser range finders and feed the info into an axon?
Of course... You just have to find it.
I'd rather hack a Bosch LASER tape though (range: a few cm to ~40m with a precision of ~1mm). - Far better than any Bushnell ranger I know of :)

Thanks for the suggestions!
-
Does anyone no where to buy these or how expensive they are???

That was surrealistic... You can always pinball it....
But hey, really now... You are surrealistic... I did some good research, feels like things have changed.
I mean 30 - 40 dollars.... That not expensive for such a system...

The ~$30 setups are only good for distances <3-4m, from what I recall - 50 feet is more in the range of 15m, and at that point you won't be able to detect the reflected laser light (short of getting a more powerful laser, or doing some filtering / modulation)

You always need to play around with hacking.
Altering the focal plane (by varying the lens distance) and maybe getting a more powerful laser yes...
But... What matters really is the focal plane... No filtering etc...
Of course that way you are altering the sensitivity of the sensor, but in a digital world range comes with a price ;-)

Those sound like good ideas!
