This variable frequency oscillator for radio transmission covers the range from 1.6 MHz to 20 MHz, depending only on the coil used. The circuit is very stable and can be used in amateur equipment.
Simple timers can be designed using inverters or any other gate that can be connected as inverter. Figure...
