-
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...

Baluncore replied to the thread Underwater piezoelectric sensor array receive sensitivity.No, you will not. The array pattern may be the same, but the magnitude of the main-lobe energy will be less. A transducer is impedance...

Baluncore replied to the thread In the early days of electricity, they didn't have wall plugs.I expect the use of Edison screw, ES, or E27 light fittings would twist and damage the power cord. Maybe bayonet cap lamps, BC, or B22...

Baluncore replied to the thread I Linear generator prototype.You can use a diode bridge to rectify the current so both the positive and the negative currents flow into the battery in the same...

Baluncore replied to the thread Collection of Science Jokes P2.I purchased two tickets with different unknown numbers in the lottery. I placed them in a Schrödinger’s box, then walked away, ignoring...

Baluncore replied to the thread I Linear generator prototype.You might try glueing two magnets together, NS+SN, to make a longer magnet, then drop them together through the one coil...

Baluncore replied to the thread A question about Emma Kok Singing.Here is Amira Willighagen, aged about 10, who had no singing teacher, and did not read music, but who, I believe, learnt to sing by...

Baluncore replied to the thread A question about Emma Kok Singing.What is your question precisely ?
-
Baluncore replied to the thread I Linear generator prototype.If the magnet is a bar with N-pole at one end and S-pole at the other, then to test the generator, turn the magnet, end for end, outside...
-
Baluncore replied to the thread I Linear generator prototype.Yes. When you slide the magnet through the core, the field does not reverse, so you get no voltage induced.

Baluncore replied to the thread I Linear generator prototype.What pole orientation does the magnet have? How is the wire wound on the core? What type of galvanometer, with what current range? The...

Baluncore replied to the thread Misc. Nonlinear rubberband type thing - "k" dropping fast as it is stretched.That response is like a symmetrical over-centre latch. Are the units mg, g, kg, tonne or N ?

Baluncore replied to the thread Looking for free Word Processor with at least some formatting features.Open Office Writer got left behind when the project forked in 2010 to create LibreOffice, which is very widely used, on MS Windows, and...
