Free electronic circuit design and schematic diagram
Sometimes, people confuse about the different of transistor and tubes. This video explains the different between transistor and tube. Basically, the transistor and tube has similar function. But the construction between them is really different. This video shows the diagram of the typical triode tube. First, comparison between NPN transistor and triode tube. The label of NPN transistor is base, […]
Read moreThis is a soldering high-brightness LEDs video. This video demonstrate a simple way how to solder the high power LED. First, use some of solder paste and place the solder place to the heatsink pad, then plant the LED to the pad. In this video, to dry the solder paste, the steinel programmable hydrant is used. The temperature of the […]
Read moreBelow is video tutorial about fundamental of signal conditioning tutorial part II. On previous video has covered about amplification, instrumentation amplifiers and filtering. On this part II video tutorial will cover about attenuation, isolation, linearization, and circuit protection. Most data aqcuitition system input can measure voltages only within range 5-10 volt. Any voltages higher than this must be attenuated. To […]
Read moreBelow is video tutorial about fundamental of signal conditioning part I from measurement computing. On this part, there are three topics will be covered. There are amplification, instrumentation amplifiers and filtering. Simple data acquisition system contain a MUX, instrumentation amplifier and ADC. Mux or called Multiplexer acts as the input switching. This device will chose which input will be amplified. […]

High-end audio equipments are normally digitally controlled by a a microprocessor (microcontroller) system. It’s necessary to have digital interface that provide control for audio signal switching, as well as programming the gain to control the signal volume. TEA6320 comes with the solution for digital control of audio source channel selector and volume control, very useful integrated circuit for modern audio […]

In the circuit the rotary converter is nothing more than a second motor which is acting as a generator. The tools motor performed this function with the static converter, but at the cost of some loss of power. The idler motor is under no physical load but it cleans up the signal with the rotary converter. The only difference on […]

Capacitor have been use for decades to operate 3-phase motors on single-phase power. Two single-phase wires are connected to two of the inputs on a 3 phase motor on this method. Then, the capacitors is connected to one of the single -phase inputs and the third leg of the motor. Here is the schematic diagram of the circuit: The voltage […]
