The proposed slow-start power supply circuit is specially designed for power amplifiers to ensure that the loudspeaker connected with the amplifier do not generate the loud and unwanted “thump” sound during power switch ON. This also implies that the power supply will safeguard or protect the loudspeaker from the sudden inrush current transient from the […]

IC 555 Astable Multivibrator Circuits
The IC 555 astable multivibrator is a configuration where the IC 555 output continuously switches between an ON state and an OFF state at a given frequency, determined by its RC timing components. Since in this configuration, the output of the IC 555 is never in a stable state, it is called an astable multivibrator. […]
How to Build a Rain Sensor Circuit
This is a simple rain sensor circuit which can be built by a school grade student very easily and can be used for displaying its relatively useful feature, probably among his friends or in a science fair exhibition. Using IC 555 as the Comparator The circuit is basically rigged using IC 555 as a comparator […]
Float Switch Controlled Water Level Controller Circuit
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 […]
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 […]
