The post narrates a simple water level controller circuit using a float switch mechanism. The idea was requested by Mr. tpraveenraj. Technical Specifications I’m a electronic hobbyist from software field. So I try with the things in the weekend. I saw your blog recently and really admired to test this circuit, and when I went […]
Newly Updated Circuit Projects:
Designing a Powerful 48V 3KW Electric Vehicle
In this post I have explained a few important parameters related to the making of a 48V 3KW electric vehicle using solar panel, including a full fledged circuit diagram for the same. The idea was requested by Mr. Sreejith. Circuit Objectives and Requirements I am Sreejith Rajan a b.tech student doing a project on electric […]
DIY Taser Gun Circuit – Stun Gun Circuit
A Taser circuit also known as Stun Gun circuit is one non-lethal electric shock producing unit used to paralyze a person for a time being without causing any severe damage or injury. It is a very useful device, especially to immobilize an attacker. Using and making of stun gun is restricted in most of the […]
Interfacing DHTxx Temperature Humidity Sensor with Arduino
In this article we are going to take a look at DHTxx series sensors, which is used for measuring temperature and humidity, both the functionality is integrated into one module. We are going to see their specification, so that you can choose best sensor for your project and finally we are going to interface it […]
Simple Digital Timer Circuit with 2 Digit Display
This simple digital timer circuit can be used to obtain timing output through selectable ranges, which can be set from 0 to 99 second, with 1 second interval, 0 to 990 seconds with 10 second interval, and 0 to 99 minutes with 1 minute interval. All these timing outputs can be visualized and tracked through […]
Password Lock Circuit Using IC 4017
In this post I will show how to construct a general purpose password based electronic lock circuit without any involvement of microcontroller. You can use this circuit for numerous applications where a basic level of security is required for turning a circuit ON. The proposed project is built using an IC 4017 and the circuit […]
