This is a Different Types of Oscillators tutorial video. This video talks about different types oscillators. There are four type of  oscillators. They are sinewave oscillators, squarewave oscilators, trianglewave oscillators, and sawtooth oscillators. Here is the video :

This is a Ohm’s Law video tutorial. This video explains how to understand the Ohm’s Law. There are three main parameter of Ohm’s Law, they are voltage, current flows and resistances. Voltage is defined by V, current flows is defined by I and resistance is defined by R. In this video, the triangle of Ohm’s Law which is used to […]

This is Electrical Voltage, Current and Resistance video tutorial. This video tells about the rules of the voltage, current and resistance. Voltage is the difference in energy level, the current is how many electrons are flowing and resistance opposes the flow of electrons. Unit of voltage is volt, the unit of current is amperes (amp), and the unit of resistance […]

This is video about series and parallel circuit. This video shows the different between series and parallel circuits. This Video also explains how the series and parallel circuits work. In the series circuit, the voltage is divided by amount of the lamp. When we pull out one lamp in the series circuit, all the lamp will turn off because there […]

This is a MOSFET transistor video tutorial. This video provides information about n chanel MOSFET transistor and how it work. When the transistor is off, no current can flow so the one of the gadget wire is disconnect, so officially the gadget stay off. When the transistor is turn on, the current can flow then he both of gadget wires […]

This is a video that provide the information about How find the resonance frequency and tune antenna wave traps. To find the resonance frequency we can use the wave traps. In this video, the wave traps is made of PVC pipe and the coils. Beside that, transceiver YAESU FT-897 or any HF receiver and grid dip meter are also required […]

This video tutorial is about building a super spy bug transmitter. In this video we can see how to build a very small home made FM transmitter bug using a single transistor. To build this device doesn’t need  much money. This devices has a transmission range of 200 meters. This video provide the schematic diagram of the circuit and the […]
