The ceramic transducers ring for a while (at the resonant frequency, obviously). The Polaroid SX-70 used a single electrostatic transducer for sonar ranging (autofocus). | |

| Mar 24, 2013 at 20:47 | comment | added | Andy aka | Sounds a neat project - any ideas what the method used in the EZ01 was to measure range? It could use a radar type ping and quickly switch the transducer over to be a receiver and detect a ping coming back. Or it may be a continuous wave circuit with a sensitive circuit that differentiates reflections from output signals? | |
