In this article I have explained the circuit implementation of an interesting concept of converting physical energy into electricity. Here I have explained a simple method of converting or channelizing the wasted gym workout energy into useful electrical energy. The idea was requested by one of the keen members of this blog, let’s know more: […]
Newly Updated Circuit Projects:
Diode Rectification: Half-Wave, Full-Wave, PIV
In electronics, rectification is a process in which a rectifier diode converts an alternating full cycle AC input signal into a half cycle DC output signal. A single diode produces half wave rectification, and a network of 4 diodes produces a full wave rectification In this post we will analyze both half wave and full […]
Remote Controlled Toy Car using 433 MHz Remote Modules
This circuit will enable reverse-forward, left-right control of a toy car through 433 MHz RF remote control modules or any similar RF remote modules. The market may be full of these hi-end remote controlled toy cars, but for a hobbyists making one at home can be entirely a different experience. The article below explains how to configure […]
Heart Rate Monitor Circuit
In this article I will comprehensively discuss a relatively accurate electronic heart rate sensor circuit processed by a few discretely wired opamp circuit stages, and subsequently we’ll learn how this can be modified for making a heart rate monitor alarm circuit. Using IR Photodiode Sensors The sensing of the heart pulses is basically done by […]
Remote Controlled Pulley Hoist Mechanism Circuit
In this post I have explained a self locking worm gear mechanism for hoisting heavy loads through an electrical motor. The main feature of the system being its self locking in an event of a motor failure. The idea was requested by Mr. Amit Patkar. Technical Specifications I love electronics, especially automation, I have been […]
Laughter Sound Simulator Circuit
As the name suggests, this device generates electronic sound, resembling human laughter. BASIC DESIGN To enable the circuit start the proposed operations, it must have a fundamental sound input or frequency for processing. This basic frequency is established through a simple oscillator operating at 1 kHz frequency. The next, requirement would be to process this […]
