This is a video tutorial about Differences in Wire Gauges. This video describes The Differences in Wire Gauges: the bigger the number of gauges, the smaller the wire. For example house wiring that it has 14 gauge or 12 gauge because the house wiring doesn’t require flexibility. For speaker wiring, it has 22 gauge, because it need flexibility. Here is […]

This is a tinning soldering iron video tutorial. This video shows how to tin a soldering iron. Tinning is when we take solder and flow it on the tip of the soldering iron. we also have tin components and wires, which will be shown in the video. The soldering iron is getting hot for first time and tin it, so […]

This is a transistor video tutorial. This video describes about transistor and how it works. Transistor can be used as amplifier or switch. There are many kinds of transistor, in this video  bi-polar transistor is described. There are two kinds of bi-polar transistor, NPN and PNP. Bi-polar transistor has three layer, they are input layer, control layer and output layer. […]

This is how to test a diode video tutorial. This video shows how to test diode using multimeter. First, put the positive probe of multimeter on anode and negative probe on the cathode, then check the value on multimeter. After that, put the positive probe of multimeter on cathode and negative probe on anode, then check the value shown on […]

This is video tutorial about how to test high voltage diodes. This video shows step by step how to test high voltage diodes. Arrange the diode like the schematic in this video. Connect DC power supply on the input. If the voltage is 6V to 10V the diode is good and connected in the right direction. If the voltage is […]

This is video about diodes in circuits and testing them. In this video, the diodes is tested in two ways, using simple circuit and using multimeter. The diodes in this video is configured in two ways, forward bias and reverse bias. In the forward bias configuration, the diodes allow the current through them, and in the reverse configuration, the diodes […]

This is a video tutorial about milling PCB using Altium Designer. This video tutorial shows step by step how to milling the PCB using Altium Designer. The Altium Designer can be used to milling PCB automatically. First, we must provide the circuit, then use the scripting system provided in Altium. Then choose the script and run it. Then export the […]
