Ερώτηση από BG151238531 επί 2021-10-01 07:44:00
lmorelli Unfortunately,no. The datasheet shows that the NE555 becomes unreliable with frequencies over 500KHz.

Ερώτηση από uka1024 επί 2018-06-09 05:13:04
lmorelli Theknock (or "bump" ) is due to the power off-power on of the system. To avoid it you should isolate the amplifier from the power source.

Ερ: hello, did anyone manage to make it work with a ultrasonic transducer? and if yes, how
Ερώτηση από MARIOS επί 2021-01-24 04:26:47
lmorelli The kit generates waveforms with a defined amplitude. You have to match the correct amplitude, frequency, waveform and impedance of your own transductor. The kit should easily reach 100 kHz, but the waveform tends to degrade above that frequency.
