    Piezoelectric Transducers

    The conversion of electrical pulses to mechanical vibrations and the conversion of returned mechanical vibrations back into electrical energy is the basis for ultrasonic testing. The active element is the heart of the transducer as it converts the electrical energy to acoustic energy, and vice...

    Led display Digital Voltmeter question

    Great Work Billy. Thanks for doing that :D . Sometime ago an internet friend told me that the kit companies are making some small faults (not by chance) on schematics to prevend them from copying :o ! If you relly on the PCB, everything will work nice, becuase it's a copy of the original...

    Convert 0-30V 3A PSU to 5A or more

    The transformer i bought was rated at 3A, but seems to be able to give more that this :D ! Also i didn't touch anything on the current limiter circuitry, I just set the current limit to full, that the strange! Staigen: I haven't done the testing yet. Sorry for that, you will have to wait some...

    Convert 0-30V 3A PSU to 5A or more

    I build it and give me around 4A output max, but i didn't let it for long time. I have not made any measurements on ripple because i haven't an oscilloscope at home, but i will do the measurements as soon as possible and i will post the results here. What you suggest to use as a low voltage -...
