ESP32 Powered Spider Man Web Shooter Prototype Maker Builds an ESP32 Powered Spider Man Web Shooter in This Brand New DIY Project

YouTuber Plentiful Props 3D has developed a functional Spider Man-inspired web shooter that combines custom electronics, 3D-printed parts, and a servo-actuated spray mechanism to fire web-like strands from a wrist-mounted wearable. The project uses an ESP32-S3 Mini development board mounted on a custom PCB to control the firing mechanism. According to the creator, the electronics package…

Smart Home Energy Management System Smart Home Energy Management System

By Ojas Chanakya, Aniruddh Viswananthan

We have developed a smart home energy management system prototype that divides the house into sectors and efficiently chooses which sector is powered by what energy source. The reason why we developed this project was that in India, the adoption of renewable energy is still not widespread, despite the subsidies and…

Smart Power Management System Smart Power management System

By Yash Chipkar

We all dread the moment our monthly electricity bill arrives. It’s often a shock—a single, confusing number with zero explanation of where that energy went. Was it the air conditioner running too long? A faulty refrigerator? Or phantom electronics draining power in standby mode? For the CircuitDigest Smart Home and Wearables Project Contest 2025, We built the Smart Power…

TI Launches Industry-First Integrated Multi-Cell Gauge TI Introduces Predictive Battery Gauges to Maximize Runtime in Portable Devices

Texas Instruments (TI) has unveiled two new battery fuel gauges (BQ41Z90 and BQ41Z50). These gauges use Dynamic Z-Track™, a predictive algorithm that is known to deliver industry-leading accuracy in monitoring battery charge and health. Setting them apart from traditional methods, this adaptive tech can achieve state-of-charge and state-of-health readings within 1% error, which helps extend…

India Relaxes SEZ Rules to Boost Electronics Government Relaxes SEZ Rules for Semiconductor and Electronic Component Factories

The Government of India has made amendments to the Special Economic Zones (SEZ) rules. This aims to promote the manufacturing of semiconductors and electronic components. The changes reduce the minimum land requirement for establishing factories in SEZs from 50 hectares to 10 hectares.

The norms that are relaxed span over semiconductors, display module sub-assemblies, printed circuit…

India Develops Fast-Charging Durable Sodium-Ion Battery India Develops NASICON Structured Sodium Ion Battery with Six Minute Rapid Charging

Researchers at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru, have developed and tested a sodium-ion-powered battery capable of hitting 80% charge in a mere 6 minutes and retaining over 80% capacity even after 3,000 cycles. This development, based on a NASICON-type anode material, is a promising substitute for conventional lithium-ion batteries for electric…

Well Cleaners Early Warning System(EWS) Well Cleaners Early Warning System(EWS)

In India, there are more than 70 lakh wells, that are both Kutcha and Pucca, in the alluvial plain regions. These wells irrigate 38% of the net irrigated area of the country and The traditional homestead type of habitation in Kerala is generally characterized by a well in each compound to tap groundwater. Therefore, it is estimated that the state has around 65 to 70…

Battery Management System Evolving Battery Management Systems

Lithium battery systems are increasingly moving to higher capacity and increased voltage levels as the trend toward electrifying mobility, tools, and industrial equipment continues. Though excellent for enhanced mobility and productivity, these higher battery cell counts and voltage levels mean that battery management system (BMS) technology needs to advance to…

Extracting Lithium in Salal-Himalaya Region of J&K Experts Explain Why J&K’s Recent Lithium Discovery will not be Able to Boost India’s EV Growth Currently

A month back, around 5.9 million tonnes of Lithium have been discovered in the state of Jammu and Kashmir for the first time, claimed by the union government. But, experts on the other hand stated that Lithium reserves were already discovered in the state back in 1999. Lithium, often known as the ‘White Gold’ is now a very important mineral as it is mostly utilized…
