A reader contributes a circuit idea for triggering a stop-motion camera setup and a dialog between the author and Electronic Design's Anoop Hegde illuminates the circuit design process. Fig 1. This ...

This circuit is very useful while checking/operating counters, stepping relays, etc. It avoids the procedure of setting a switch for the required number of pulses. By pressing appropriate switches S1 ...

The hobby circuit below uses an unusual method to generate about 12,000 volts with about 5uA of current. Two SCRs form two pulse generator circuits. The two SCRs discharge a 0.047uF a 400v capacitor ...

How to build a circuit that converts capacitance into a pulse train. Test results of the circuit design. The circuit in Figure 1 allows you to convert capacitance into a pulse train by using a ...
