Laboratory Power Supply Project This Power supply project is aimed at those who want to design a laboratory power supply. In addition to adjustable voltage feature, a laboratory power supply has a current-limiting and also short-circuit protection. This is a high-quality laboratory power supply with adjustable variable output continues stabilized at any value of 0-30V DC. This power supply circuit [...]
90W Switching Power Adaptor Circuit This is a AC to DC switching power adaptor circuit with maximum output power of 90W. Switching power supply is built using a high voltage power switching regulator IC MC33374 and some other additional components. The MC33374 IC is a monolithic high voltage power switching regulators that are specially designed to operate directly from a [...]
DIY PCB Fabrication Process Any electronics hobbyist always wanted to experimental results realized in the form of a professional PCB. But many obstacles they faced in realizing that in a good process of PCB fabrication. Many things must be prepared to start from raw material of PCB, the design process, the stages of completion. PCB Fabrication Method Here is a [...]
AC LED Circuit This is a simple AC LED Circuit for 110V or 220V AC power. This can work well using just a few components. This LED circuit is useful for power-on indicator on the panel board such as AC voltage control system installation. You can use color LED you like, especially the bright colors like red, white, or green. [...]
Easy DIY PCB Many pages on the Internet devoted to various ways to hobbyists make their own PCB (DIY PCB). All the methods that they develop themselves through a refinement process based on the experience they have. Each method has some drawbacks and advantages. Here is a good method for making DIY PCB that gives almost perfect results every time [...]
