This video tutorial is bout creating arbitary pads in Altium designer. This video shows how to make arbitary pads in Altium Designer. The components with pad shape other than the regular rectangular, rounded, octagonal etc can be created using Altium Designer. Step by step to create the pads shape are shown in the video. Here is the video tutorial:
Read moreThis is video about oscillator simulation using ORCAD. In this video, first simulation is simulation of the schematic without ipulse of current (current source), the result is go wrong. To correct the result, we add the ipulse of current and set it. After that, the result of second simulation is there are five waveform. Here is the video tutorial:
Read moreThis is a video tutorial of making and simulate voltage divider using ORCAD. This video shows how to use ORCAD in making voltage divider. First, create the new project by clicking file>new>project. Then click place>part, then choose the components those are required. Using ORCAD we can edit the components properties. To simulate the schematic, click PSpice>new simulation profile. Then edit […]
Read moreThis is a video about making a PCB with solder mask covered. To make a PCB with solder mask covered, we must prepare the tools such as heat transfer machine, hydrochloric acid, hydrogen peroxide, a laser printer, peel-n-press paper, PCB green oil, and ultraviolet lamp. Print the circuit to the peel-n-press paper, set the temperature of heat transfer machine at […]
Read moreThere are several integrated circuit chips designed specially for LDO (low drop out) voltage regulator. Building LDO using standard op-amp and discrete components can be an alternative. Here is one design of LDO circuit: Here some guidelines to select the components values: D1 is chosen for the best performance, the sharper the on-off transition curve the better. Some people say […]
Read moreThis is double sided PCB video tutorial part 2. This video shows step by step how to make double sided PCB. After we transfer the printed circuit into the board, we cover the board using green film by using laminator. Then, use the ferrite chloride to get the route of the PCB. After that, drill it. After we done the […]
Read moreThis is double sided PCB video tutorial part 1. This video shows step by step how to make double sided PCB using toner transfer method. This video uses PCB fab in a box kit and the laminator. First, print the the top circuit and bottom circuit into the transfer paper. Then cover both side of board with a printed circuit. […]
