The transistors VTi, VT3, and VTs, along with the RC components, form three distinct multi-resonator oscillators. The oscillation frequency levels are dependent on the values of Ri, R3, Rs, and Cl, as well as Cz and C3s. The circuit comprises...
The design of the power supply circuit diagram utilizes an oscillator circuit from the 74HC series of CMOS logic circuits, with a MOSFET as the switching device. This configuration allows for the development of small-scale power supplies suitable for...
The circuit utilizing Optical Electronics 9803 operational amplifiers separates an audio frequency (AF) input signal into two outputs. The low-pass output allows frequencies from DC up to 10 Hz, while the high-pass output encompasses frequency content above 10 Hz,...
A 12V to 20000V inverter circuit diagram (stun gun) is presented. This circuit generates a very high voltage and must be used with caution to prevent electric shock. The transformer can produce over 1000V and amplify the voltage by...
The heatsink on the triac is somewhat unclear. A maximum value of 10°C/W has been calculated, which raises concerns. The calculation is as follows: (maximum temperature - room temperature) / (maximum on-stage voltage * (milliamps / voltage) - junction-to-base...
A touch dimmer circuit is illustrated in the accompanying diagram. It utilizes a finger touch control piece to enable the turning on, off, or stepless adjustment of incandescent lighting. This circuit is applicable in dimming filament lamps and for...
