itacts as a quick check for potential thermalproblems by simply probing a suspiciouscomponent with the sensingdiode. The circuit, including the indicatingmeter, can fit into a small housing,such as an empty 20g glue-sticktube. An ordinary 1N4148 silicon signaldiode serves as the temperat...
One of the main applications of diodes is inpower supplies. An AC to DC power supply can be made either by using a basic single diode to form a half wave AC to DC power supply or, by using 4 diodes in a bridge network configuration to create a full wave AC to DC power supply circ...
The FET untuned oscillator circuit consumes roughly 2 mA from the 6-volt DC source. With this source voltage, the open-circuit RF Output voltage is around 4% volts rms DC supply voltages as much as 12 volts could be applied, with correspondingly increased RF output. To find out if theosc...
This poster explores and documents the nonlinear behavior exhibited by a sinusoidal driven serial circuit consisting of a resistor, an inductor, and a diode (all available from Radio Shack). Power and frequency transitions to chaos are demonstrated. The circuit exhibits period doubling, transitions ...

And then SW1 is used to turn on-off the next circuit as a sensor, control, battery charger, and lamp circuit. First of all, in normally power the lamp go out not light since current pass to R4 to the base of Q1 cause it is bias so high current flow through D2-diode, R5-resisto...
Simplemotion sensor circuitusingTransistor amplifier. The output current of the module will flow through R1 as a biased current to the base of Q1. It causes Q1 to conduct current or turn on and drives a main current through R2 and LED1, lighting it up. ...

The entire circuit is operated with two transistors, two diodes, and few passive components. If the testing crystal is good then it operates as an oscillator in combination with a transistor. The diode rectifies the output of the oscillator and the capacitor filters the output. This output is...
Idea inFigure 2shows an alternative circuit which solves all these problems at once. The source is shown as a 5 volt AM modulated signal in series with a 5 volt DC source (which can be ignored here). The AM signal is a 1MHz carrier with 1kHz modulation at 100%. The input impedance ...
