active filter circuit

The circuit is designed to fit snugly, eliminating the need for adhesive. It is recommended to test the fit multiple times, making incremental adjustments until a snug but movable fit is achieved. The entire circuit should be placed inside...

The circuit does not fail under slight variations, even if the input/output electric current characteristics are exceeded. Failure occurs only during a short circuit or extreme conditions at the output. The operation of the circuit is explained as follows:...

This article is relevant only to readers whose bicycle lights are powered by a dynamo. The regulations regarding bicycle lights in the United Kingdom are stricter than in many other countries, making dynamos a rarity in the UK. For...

This circuit is a metal detector designed to detect large metallic objects at depths ranging from 2 to 3 meters, depending on the size of the object and the type of soil. The construction is straightforward, making it accessible...

These circuits are commonly utilized in robotics to enable DC motors to operate in both forward and reverse directions, as well as to provide an electric brake (short circuit condition). H-bridges can be found as integrated circuits or can...

The schematic for this project is not overly complex; however, it is crucial to understand the circuit board and its operation due to the high voltages generated. Below is a rough draft schematic of the camera used for this...
