A Common Cathode LED strip is being utilized instead of a Common Anode variant, leading to the development of a modified circuit. The experience with FETs was limited, resulting in challenges as a minimum voltage equal to Vcc is...
The circuit operates based on the principle that neon tubes N1, N2, and the photosensitive resistor RG1 form an optocoupler. When a finger touches the metal sheet S1, N1 lights up, causing RG1's resistance to decrease. This reduction allows...
The circuit utilizes condenser microphones to detect sound and convert it into signal variations. This signal is then processed through directly coupled transistors VT1 and VT2, which form an amplification stage before being fed into a switching circuit. The...
The automobile delayed kill switch operates on a straightforward principle. Upon exiting the vehicle, a hidden pushbutton switch is activated. Although no immediate effect is visible, after a preset duration, a relay engages and locks in place. This action...
This circuit will light a lamp at a remote location when the doorbell switch is pressed. This circuit should only be used with the solenoid type doorbells; the electronic type that play tunes will not work here. It is...
When switch S1/2 is activated, it powers the circuit C1, which utilizes the UA741 operational amplifier for voltage comparison. Pin 3 serves as the non-inverting input, while pin 2 is the inverting input. The voltage at pin 3 is...
