In this post I have explained a simple ATX UPS circuit with an automatic charger for enabling an automatic changeover from mains to battery power during mains failures and for ensuring an uninterruptible operation of the ATX load. Technical Specifications I´m interested in your site and there are a lot good ideas. But for my […]
Newly Updated Circuit Projects:
5 V to 10 V Converter for TTL Circuits
In this post I have explained a simple 5 V to 10 V converter circuit which can be used in TTL circuits where only 5 V is available and converting this 5 V to 10 V can be extremely useful for operating an adjacent circuit which may require a supply of around 9 V or […]
How to Measure Dissolved Oxygen in Liquids
In this post I have explained a sensor device used for measuring the level or amount of dissolved oxygen in water and other fluids. The idea was requested by Mr. Amit Technical Specifications I didn’t find sensors or sensor modules for Dissolved Oxygen or pH readings for us to use with controllers for our projects. […]
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 […]
Make this Solar Powered Fence Charger Circuit
A Fence charger or energizer is an equipment which is used for charging(electrifying) a fence or a boundary in order to protect the inside premise from human or animal interventions. Since these boundaries are mostly of large fields and parks, are normally away from the main cities, and powering them through some renewable option becomes […]
How to Make a GHz Microwave Radar Security Alarm Circuit
In this post I have explained a GHz microwave radar security alarm circuit which is designed to detect an intruder within the critical zone only while it’s moving, static objects produce no effect for the sensor. Using Doppler Sensor KMY24 In the previous article I have explained about a microwave Doppler radar sensor module KMY […]
