What is an Earth Torque Generator (ETG)? A New Concept for Unlimited Clean Energy
Contributor Credit: This conceptual proposal and the structural framework of the Earth Torque Generator (ETG) have been developed and contributed by Mr. Ike Higgins, continuing his ongoing dedication to introducing public-domain concepts for environmental restoration and planetary healing. Introduction In an effort to continue my quest to get new ideas for technology that will help […]
Rotating LED Chakra Circuit for God Idols
LED Chakra is an ornamental lighting system which depicts or imitates a rotating wheel like appearance, by means of sequentially shifting Illuminated LED arrays. Indian subcontinent is a land of festivals and celebrations which mostly start from the month of August and continues until the New Year. All these festivals have one fundamental thing in […]
DIY Power Bank using T856-C Module? How to Connect
So here we are talking about one small board called T856-C. We use this little module when we want to make one DIY power bank at home, like those we use to charge phones and other USB things. It can charge one 3.7V Li-ion battery like 18650 and also give us 5V output to run […]
Adjustable CDI Spark Advance/Retard Circuit
In this post we’ll learn about a simple circuit which allows a manual adjust feature for the spark timing of a motorcycle’s CDI either to achieve an advance ignition, retarded ignition or simply a normal timed ignitions. After a comprehensive study regarding the subject I was apparently successful in designing this circuit which can be […]
18650 2600mAh Battery Datasheet and Circuit Diagram
In this article I will try to explain the main specifications and datasheet of the Li-Ion cell 18650 2600 mAh, which is one of the most popular Li-ion batteries, and preferred by all electronic professionals due to its high efficiency, in terms power delivery and compact dimensions. Li-Ion batteries are one of the most advanced […]
