Look at the McIntosh MA230 carefully. It shows the right way to do the cathode and plate windings thing, which you also see in some Fishers, the original Quad, and lessee, that Bogen there.DIY IR Sensor Module Circuit Diagram
IR sensor circuit basically consist an IR LED and a Photodiode, this pair is generally called IR pair or Photo coupler. IR sensor work on the principal in which IR LED emits IR radiation and Photodiode sense that IR radiation.Bipolar transistor biasing
The fixed bias circuit is modified by attaching an external resistor to the emitter. This resistor introduces negative feedback that stabilizes the Q point. From Kirchhoff's voltage law, the voltage across the base resistor is = − − From Ohm's law, the base current is = The way feedback controls the bias point is as follows.Automatic Street Light Controller Circuit Using Relays and LDR
Description. The circuit diagram present here is that of a street light that automatically switches ON when the night falls and turns OFF when the sun rises.In fact you can this circuit for implementing any type of automatic night light. The circuit uses a Light Dependent Resistor (LDR) to sense the light .When there is light the resistance of LDR will be low.Automatic 12v Portable Battery Charger Circuit using LM317
This automatic battery charger circuit is mainly involves two sections – power supply section and load comparison section.. The main supply voltage 230V, 50Hz is connected to the primary winding of the center tapped transformer to step down the voltage to 15 0 15V.LMx24, LMx24x, LMx24xx, LM2902, LM2902x, LM2902xx ...

The bridge rectifier circuit diagram consists of various stages of devices like transformer, Diode Bridge, filtering and regulators. Generally all these blocks combination is called as regulated DC power supply that powers various electronic appliances.. The first stage of the circuit is a transformer which is a step down type that changes the amplitude of the input voltage.Pulsed Induction Metal Detector Old Radio Builder
This is my version of a Pulsed Induction type of Metal Detector. I named it "Blind Squirrel" because even a blind squirrel finds an acorn every now and then.LED Chaser circuit with PCB layout | Running lights ...
Chaser circuit using IC 4017 IC 555. If you want to build a 10 LED Chaser circuit we recommend this circuit first. The working principle. In the circuit above, IC555 IC1 is popular timer IC as the Astable Multivibrator or free running pulse generator, which the output pulse frequency at pin 3 of IC1 is determined by R1, R2 1.5K, VR1 100K, and a capacitor C1 1uF.
