An automatic clock time triggered water level controller circuit which responds to a real time clock input is discussed in the following article. The design also includes a water detection stage which makes sure the initialization takes place only in the presence of water in the tank or the pipe. The idea was requested by […]

Simple Walkie Talkie Circuit
In this article I have explained a simple walkie talkie circuit that can be easily built by any hobbyist and used for communicating between rooms or floors or simply for having some fun across neighbors and friends. The range of this system is around 30 meters. A walkie-talkie, also commonly referred to as handheld transceiver is […]
0.6V to 6V/12V Boost Converter Circuit Diagram
In this post I have explained how to make a 0.6V to 6V or 12V boost converter circuit using a single chip MC74VHC1G14, which uses under 1V to operate. About the IC MC74VHC1G14 Normally, we all know that a silicon transistor would find it difficult functioning below 0.7V, unlike germanium counterparts which are capable of doing it […]
Programmable Automatic Starter Circuit for Diesel Water Pump
In this post I have explained a programmable Auto-Starter circuit which may be used for getting a pre-programmed set of automatic sequential operations over a Diesel Water Pump as intended by the user. The idea was requested by Mr. Scott. Technical Specifications I am currently trying to figure out how to make up an auto […]
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 […]
Remote Controlled Wireless Water Level Controller Circuit
For multi-storey buildings where water tanks could be at considerable heights over building terraces, monitoring the levels automatically could become a major issue. RF remote control modules have become pretty cheap nowadays which could be effectively used for solving the inconvenience. I have explained how to make and install a wireless water level controller circuit […]
