The integrated circuit used in this trigger is uncommon today. We found it in a documentation from the 70s. The circuit operates with signals up to 50 kHz.
What we have is a powerful flasher that can be powered by voltages of 12 V like the one obtained from...
A 0 V signal initiates sampling on this circuit suggested by documentation from the 1970s. The...
This circuit is used with low impedance microphones, such as small speakers, magnetic capsules of...
