Satellite Signal Strength Meter Circuit
Here I have explained how to make a simple inexpensive satellite signal strength meter which can be used for aligning dish antennas with local satellites in order to achieve the correct positioning and maximum signal strength from the antenna. How LNB Works The LNBs that are used for receiving satellite signals (digital or analogue) are […]
How to Generate Electricity from Road Speed Breakers
Free Energy is available all around us in a variety of different forms, it just needs to be appropriately harnessed and used. One such example is our modern streets and roads where thousands of heavy and small vehicles pass everyday non-stop. Electricity from Roads The amount of energy transferred across the roads by these vehicles […]
Water/Coffee Dispenser Motor Circuit
In this article I have explained a protection circuit which may be used for preventing a “dry run” situation in mini coffee dispenser motor pumps, by sensing the slight difference in its wet and dry current consumption levels. The idea was requested by Mr. Ken Adler. Technical Specifications I read with great interest your post titled, […]
Car Radiator Hot Indicator Circuit
The proposed circuit is very useful which warns the car driver before hand once the radiator gets heated up above the preset level. How it Works The working of this circuit is very simple and works off on the car battery. The familiar IC555 is used here which is the heart of the circuit. The […]
Flashing LED Battery Low Indicator Circuit
In this post I have explained a simple low/normal battery voltage status indicator circuit through a flashing and a constant LED, where the flashing LED indicates a normal status while the solid indicator warns against a low battery condition. The idea was requested by Mr.Alf. Technical Specifications Hi, I found and built your “Low Battery […]
