Hi.
Does any body know if this device is working just like those common ultrasonic range meters which the circuit is available on internet?:
**broken link removed**
Those circuits are working not more than 4 to 5 meters, so how does this ready device is working at more than 15m?
What is the story of the laser in the link too? Is it there just as a pointer or...?
