The majority of newbie electronic hobbyists would certainly have a couple of burned up power transistors such as 2N3055 hiding inside their junk box. Supposing we have their internal semiconductor junctions still intact, the device could be transformed into a nice little solar cell by filing or sawing off the top cap of the device, […]

Designing a Powerful 48V 3KW Electric Vehicle
In this post I have explained a few important parameters related to the making of a 48V 3KW electric vehicle using solar panel, including a full fledged circuit diagram for the same. The idea was requested by Mr. Sreejith. Circuit Objectives and Requirements I am Sreejith Rajan a b.tech student doing a project on electric […]
3 phase Solar Submersible Pump Inverter Circuit
In this post I have explained a simple 3 phase solar submersible pump inverter circuit which can be made by configuring a few ICs and a few power devices. The idea was requested by Mr. Lufono and Mr. Sami. Circuit Objectives and Requirements First of all i must say thanks to you and Mr. Lufono, […]
Remote Controlled Solar Lamp Intensity Controller Circuit
In this post I have explained a simple remote controlled solar lamp intensity controller circuit which can be used for controlling the street lamp LED intensity without practically reaching for the LED box. The idea was requested by one of the dedicated members of this website Circuit Objectives and Requirements I have successful build this […]
How to Make a Shake Powered Flashlight Circuit with Magnets and Coils
In this post I have explained a shake powered flashlight circuit using an simple copper coil and a magnet. The idea was requested by Mr. Dennis Bosco Demello The Design Electromagnetism was proved way back in 1873 my Maxwell, and later by Faraday, and amazingly the technology still forms the backbone of all the major […]
Single LM317 based MPPT Simulator Circuit
To make this simple MPPT circuit we first modify a standard LM317 power supply circuit into a buck converter then configure it with a solar panel for implementing an MPPT function. Modifying a LM317 Power Supply into an MPPT Solar Optimizer In our previous article I have explained how a standard LM317 power supply could […]
