This project explains how to build a fully automatic ultrasonic water level controller where the water pump motor starts automatically when the tank level goes below a preset LOW level and stops automatically when the tank becomes FULL. The whole system is wireless, reliable, and there are no corrosion problems because the ultrasonic sensor never […]

Adding a Soft Start to Water Pump Motors – Reducing Relay Burning Problems
In this post I have explained a few innovating and simple soft start circuit examples which may be implemented with heavy duty motors so that they are able to initiate with a soft start or a slow sluggish start instead of a sudden, bumpy start Why Soft Start is Crucial for Heavy Motors When heavy […]
Ultrasonic Wireless Water Level Indicator – Solar Powered
An ultrasonic water level controller is a device which can detect water levels in a tank without a physical contact and send the data to a distant LED indicator in a wireless GSM mode. In this post I will show how to construct a ultrasonic based solar powered wireless water level indicator using Arduino in […]
5 Simple Water Level Controller Circuits
An automatic water level controller is a device which senses undesired low and high water levels in a tank, and switches a water pump ON or OFF accordingly to maintain an optimal water content in the tank. In this article I have explained 5 simple automatic water level controller circuits which can be used for […]
Make Free Drinking Water from Sea Water
In this post I have explained a cheap yet effective method of desalinating large quantities of sea water into free drinking water at home. The idea was requested by Mr. Mike. Technical Specifications This is Mike Cardenas and am writing to you with reference to your invention of a Solar Water desalination set-up from 2011 […]
How to Generate Electricity from Sea Waves – 2 Simple Methods
In this post we investigate a couple of quick and efficient methods of generating free electricity from the sea waves which is limitless and an infinite source of energy. Introduction Just like wind and sun, sea is another example of massiveness and a potential raw energy source that may be harnessed for acquiring electrical power. […]
