And this hack has some whiskers on it too.
Nothing wrong with it mind you, it’s just been around for a long long time, like since 1998 long, if not longer.

I VPed The Robotics Club of Yahoo for six years, and it’s made the rounds there since I was on board!

so, that said, this device falls short on two levels… one, it can not distinguish levels in its current setup, and two, it has a very low sample rate in its current setup. _that_ said, no, it can not create images. thank you.

Or you smokeing? This is just the sonar device, not the optics. The only use of this device is to calculate dist

He’s hacking a component from a camera (that probably has microcontrollers in it) to interface with his own microcontrollers. Seems pretty straightforward (and rather cool) from here.

Anyway. Since hackaday is slashdotting (err… hackadaying?) sites now, maybe they should just link to cached copies in the future rather than using direct links. ;)

I’m pretty new to this robotics thing.

can I build a robot to find my remote controls?

I even built a project around it back in 1994. judging from the code in the linked article, the module from the camera is a little more usable. the old module had separate pulse init and echo received lines, and the echo line would trip on the outgoing pulse, necessitating a delay before looking for the echo.
