An MPPT as we all know refers to maximum power point tracking which is typically associated with solar panels for optimizing their outputs with maximum efficiency. In this post I have explained the 3 best MPPT controller circuits for efficiently harnessing solar power and charging a battery in the most efficient manner. Where an MPPT […]

How to Make an ATX UPS Circuit with Charger
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 […]
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. […]
How to Illuminate 1 Watt LEDs with Cell Phone Charger
Nowadays probably all of us have a spare cell phone charger lying idle in our cupboards or table drawers……so wouldn’t it be a great idea if we could employ it like a super bright 1 watt LED driver and illuminate our room with white cool moon light. Circuit Concept As we all know that a 1 watt […]
Arduino Battery Level Indicator Circuit
In this post, I will show how to construct an Arduino based battery level indicator, where a series of 6 LEDs show the level of the battery. If you are interested in monitoring and maintenance of your 12V battery, this circuit might become handy. Why Battery Level Monitoring is Crucial All batteries have certain voltage […]
