This linear amplifier provides a 10-W PEP output with a 1.25-W drive on the 10 m band. The transformers, T1, T2, and T3, consist of 10 turns of bifilar windings on an FT-50-43 toroidal core and are designed for...
The adjustment potentiometer RP can modify the sensitivity of the device. Capacitors C1 function as an anti-light interference mechanism for instantaneous action. The adjustment potentiometer (RP) is a variable resistor that allows for fine-tuning of the device's sensitivity. By altering...
Tro telephones can be utilized as an intercom through the implementation of this circuit. Traditional rotary phones, particularly those that are non-electronic, may be the most effective for this purpose. Additionally, this method can also power handsets alone. The circuit...
This is a door knob touch alarm designed for home security purposes. The alarm will activate when someone touches the metal door knob. This circuit will not function on a fully metal door. Currently, circular batteries are used, but...
A brief history: Like many tutorials, this one begins with a historical overview. However, it must be noted that there is limited background information available regarding the development of 7-segment displays. 7-segment displays are widely used electronic components that...
A passive light-emitting diode output level indication circuit. This circuit utilizes a light-emitting diode (LED) to provide a visual indication of the output level from a given source. The design is characterized by its passive nature, meaning it does not...
