This circuit was found in a Japanese publication in 1975. It provides 30 W per channel using the SI-1030G modules. The module must be mounted on an excellent heat sink.
This circuit monitors extra-low frequency (ELF) fields. We found it in an American documentation from the...
We can use any type of resistive transducer with central resistance in the range of 10 k ohms to 1...
This circuit controls two lamps so that when one increases in brightness the other decreases. The...
