This video tutorial is about gerber files. This video shows how to create and edit the gerber files. Before edit the gerber file, make sure that the PCB layout is correct. After that, make gerber file by selecting file the fabrication outputs then select gerber files. In Gerber setup we can edit the general, layouts, and drill drawing. In general […]

This is WLED-display backlight driver circuit. This circuit can be used to power WLEDs by replacing the voltage-feedback network with a series current-sense resistor, R3, and the WLED strings. This circuit uses The TPS6108x that drive some series WLEDs in parallel for backlighting larger displays. Here is the circuit:The feedback of this circuit is The voltage across the current-sense resistor. […]
Read moreThis is component placement video tutorial. In this video tutorial, how to place the component is described. To place component to the PCB, the component can be dragged into work place. The component can be rotated on workplace. Each component should close each another, so the size of PCB can be reduced. Here is the video:
Read moreThis is attach footprint video tutorial. This video describe about how to attach footprint. To attach footprint, select the component then edit the footprint of component. We can add the custom footprint into the component. Here is the video tutorial:

This is Adjustable Constant Current Regulator circuit. This circuit can be used in a bench power supply to prevent the circuit that are tested from being damaged. This circuit can be adjusted to any value from a few milliamp to about 500mA. The max current is 500mA because it is the limit of the BC337 transistor in the current-limiting part […]
