In this post I have explained how to make a simple washing machine using a single motor and a cam shaft mechanism, cheaply. The Concept Washing machines are costly devices which may not be affordable for a section of the population and also to villagers who even might not have an easy access to these […]
Newly Updated Circuit Projects:
Heater Controller Circuit Using Push-Buttons
Controlling a heavy electrical appliance with push buttons can be extremely convenient since it allows a solid state approach for operating the parameter both ways up and down by mere push of the relevant buttons. Here I have explained a heat controller circuit using a set of push buttons and PWMs. Using a Digital Push […]
Making a Stethoscope Amplifier Circuit
In this post I have explained how to make an electronic stethoscope amplifier circuit for enabling a loud audible reproduction of the heart beats which is being diagnosed. The article also reveals how the same can be applied within a cellphone through a wireless circuit. The idea was requested by Dr. Ankit. Main Requirements The […]
Mini Welding Machine Circuit for Small Welding Jobs
A welding machine is an electrical device which is able to generate a very high current at relatively low DC voltages. This high current output can be suitably used for creating the intended welding arcs and welding joints. The welding joint is created by fusing the welding rod on the joint area through a high […]
Remote Controlled Submersible Pump Circuit
In this article I have explained a simple remote controlled submersible pump circuit which could be simply configured using any standard 2 channel 433MHz remote control modules. The idea was requested by Mr. James Smith Circuit Objectives and Requirements I have read a lot of your post and have successfully implemented them several times. Now […]
Pressure Cooker Whistle Counter Circuit
This circuit is designed to sense the whistles from a pressure cooker and count the number over a digital display. The system relieves the user from the stress of constantly monitoring the cooker and from manually counting the whistles. The idea was requested by Mr. P.K. Bajpai Design Concept In many of the Asian countries […]
