How Buck-Boost Circuits Work
We all have heard a lot about buck and boost circuits and know that basically these circuits are used in SMPS designs for stepping up or stepping down a given voltage at the input. The interesting thing about this technology is that it allows the above functions with negligible heat generation which results in a […]
PIC Tutorial- From Registers to Interrupts
Before getting into the minute details of PIC programming, it would be first important to learn a few good programming methods. Understanding Registers To begin with suppose you type a ;(semicolon) at any point of the program, all’s that come after this semicolon would get ignored by the compiler, until of course the carriage get’s […]
Programmable Bidirectional Motor Timer Circuit
In this post I have explained a programmable bidirectional motor timer circuit for controlling a custom industrial mechanism. The idea was requested by Mr. Milton Technical Specifications I am a glass specialist, pretty good with DIY etc, but not too hot on electrics. I am planning a build for a 10mm Toughened Glass Watch display […]
Poultry Feed Controller Timer Circuit
In this article I have explained a timer circuit specifically designed for detecting a poultry feed controller ON time period, and alarming a buzzer once the set time elapses. The idea was requested by one of readers of this blog. Technical Specifications Hello, I am a broiler poultry farmer. I have no electronic knowledge or skills. […]
Non-Contact Cable Tracer Circuit
In this post I have explained a simple non-contact cable tracer circuit which can be used for locating faults in long wound cables and wire bundles without a physical contact. The Circuit Concept Why would you shred $100 to buy a cable tracer when it is easier to develop one spending less than $10! This […]
