This circuit implements a 3-way control, with outputs in A, B and C, using CMOS integrated circuits. I found this circuit in an old publication from 1978.
We found this circuit in a 1995 paper. The reed switches are surrounded by a few coils of coarse...
This circuit can supply voltages in the range of 8 to 20 V with a maximum current of 3 A. The...
If mounted with SMD components, this spy transmitter for the FM range can fit into a pen. The...
