Linear Hall-effect ICs are magnetic sensor devices designed to respond to magnetic fields to produce a proportionate amount of electrical output. It thus becomes useful for measuring the strength of magnetic fields, and in applications that require an output switched through magnetic triggers. The modern hall effect ICs are designed with immunity to most mechanical […]

Wheel Rotation Detector Circuit
In this post I have explained a simple wheel rotation identifier or detector circuit which can be used for ensuring a continuous rotating movement of a concerned wheel through an LED, photodiode arrangement. The circuit was requested by nzb109. Technical Specifications I want to generate a trigger circuit to detect that a WHEEL is stationary. […]
Bipolar Transistor Pin Identifier Circuit
In the proposed BJT pin identifier circuit when the circuit is switched on, two jumpers will have both LEDs ON and the third will have only one LED illuminated. Investigated, Modified and Written By Abu-Hafss The E-B-C, NPN/PNP Detector Concept The jumper with one LED ON is connected to BASE. If it is red LED, […]

Easy to Build Circuit Ready availability of cost effective components can be deployed to fabricate tilt sensor alarm in ultra transistor based simple circuit. The domestic version of tilt sensor explained here is […]
Cellphone Low Battery Cut-off with Indicator Circuit
In this post I have explained a simple yet effective low battery cut-off with indicator circuit which can be integrated with cell phone/tablet charger battery packs in order to monitor and avoid battery draining below a set threshold. The idea was requested by Mr. David. Technical Specifications Hi Swagatam. I know it was asked before, […]
Simple Audio Spectrum Analyzer Circuit
In this post I have explained a simple yet accurate spectrum analyzer circuit which can be easily made at home and used for analyzing the audio from a music system or simply as a decorative musical device. What is a Spectrum Analyzer A spectrum analyzer is basically a device which is technically used for assessing […]
