Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: In this post I will comprehensively explain nine best yet simple solar battery charger circuits using the IC LM338, transistors, MOSFET, buck converter, etc […]

Long Duration Timer Circuit using IC 4541: Working and Calculations
The CD4541B is a CMOS programmable timer IC, and we use it where long delay interval is needed for a load, and also for jobs like frequency division, or timing pulse work. And all this happens with only just a few outside parts, not much around it. With ordinary IC 555, when delay becomes too […]
XL6009 DC-DC Converter IC: Pinout, Working, Circuit Diagram, and Applications
XL6009 is a DC-DC switching regulator IC, and we use it where lower voltage DC has to be lifted higher, or sometimes changed other ways, boost, buck-boost, flyback, even inverting, all that is possible depending how outside parts are connected. Why XL6009 is More Efficient Than Linear Regulators It is not like old regulator types […]
Higher Variable Output Voltage from IC 7812
You may have often wondered whether it was feasible to get higher voltages than 12 V from a 7812 IC? In this short post I have explained how to configure the IC 7812 with a BJT stage, so that its output can be made variable for achieving any desired voltage higher than 12 V, without […]
2 Simple MOSFET Gate Driver Circuits using BJTs
Very often we see that output coming from a microcontroller, oscillator, comparator, or PWM stage is just not strong enough for driving a power MOSFET directly, it gives signal, yes, but gate does not respond properly unless some decent current reaches there. A MOSFET gate behaves like a small capacitor, so now unless that gate […]
7 Simple Continuity Tester Circuits Explained
If you are looking for a simple circuit to test continuity of wires and long conductors, the explained 7 easy to build continuity circuits are the ones which you can try and might fulfill your requirement. What is a Continuity Tester A continuity tester is a device which is used for identifying the correct continuity […]
