3 Phase Induction Motor Speed Controller Circuit
In this post I will explain the making of a simple 3 phase induction motor speed controller circuit, which can be also applied for a single phase induction motor or […]
Temperature Controlled DC Fan Circuits
Have you ever turned up your amplifier all the way, either at a party or just for fun? You may have noticed that “it gets hot” and thought that a […]
SCR Shunt Circuit for Protecting LED Drivers
The post presents an effective method for protecting capacitive LED driver circuits through an SCR shunt regulator circuit and explains how it can prevent filter capacitors from blowing of and […]
RC Helicopter Remote Control Circuit
In this post I will explain a simple RC helicopter remote control circuit using 433kHz RF modules, without any microcontroller or complex joystick implementations. The idea was requested by Mr. […]
Testing Alternator Current using Dummy Load
In this post I will explain a method of checking or verifying alternator maximum current delivering capacity using a shunt regulator as the dummy load and an ammeter. The idea […]
