In this post I have explained how to make a sunrise/sunset simulator circuit using LEDs and just a couple of BJTs. The idea was requested by Mr. Jerry Circuit Objectives and Requirements Apparently natural daylight is best for humans in regulating our circadian rhythm. I would like to build an LED lighting circuit to control […]
How to Design a Solar Inverter Circuit
When a DC to AC inverter is operated through a solar panel, it is called a solar inverter. The solar panel power is either directly used for operating the inverter or it’s used for charging the inverter battery. In both the case the inverter works without depending on mains utility grid power. Designing a solar […]
