Baluncore replied to the thread I need a concave mirror with a focal length of 150 feet.I think you should mount the lens, fixed and aimed at the target, then track the Sun with a flat-mirror heliostat, mounted on a clock... -
Ah got the wiring messed up, ok now; apologies for having wasted your time; thanks for your patience! Martyn

Baluncore replied to the thread Underwater piezoelectric sensor array receive sensitivity.If you think of the transducers as voltage sources, then you would connect the transducers in series. Seen as current sources, you would...
-
Baluncore replied to the thread Underwater piezoelectric sensor array receive sensitivity.I believe the transducer is a bidirectional or reciprocal device that can work as a transmitter or a receiver. It is connected to the...
