OPPORTUNITY: Rare Earth Or Rare Ingenuity? India Remains Between The Two
With China firmly controlling rare earth exports, India confronts a critical moment in its technological trajectory. The challenge is no longer limited to mineral access; it lies in innovation itself. The key test is whether Indian startups, scientists, and policymakers can reduce reliance on rare earths through magnet-free motor designs and advanced materials development.

PURCHASE: Buyers’ Guide: Leading Suppliers Of SMT Automated Storage Solutions For Components
Automated SMT (Surface Mount Technology) Component Storage Solutions are advanced, near-line systems designed to efficiently manage electronic components, including reels, trays, and feeders within modern manufacturing environments. In SMT manufacturing, every component is unique, costly, and typically packaged on reels or tape. Since SMD reels are treated as individual pick items, each must be retrieved precisely when needed. To maintain component integrity, especially for moisture-sensitive devices (MSDs), proper storage conditions are essential. These components are generally stored at 20-24°C with relative humidity below 60%, ensuring compliance with MSL requirements. The entire process of storing at required temperature and maintaining FIFO along with manual picking is a very tedious task. |

CIRCUIT IDEA: Multi-Use RF Relay Control System
This RF-based relay control system enables safe and efficient switching of AC loads, including lights, fans, and pumps. Typical operating range is 30-50 metres indoors and up to 100 metres in open outdoor areas, depending on antenna quality and installation conditions. | | |
Do-It-Yourself
PROJECT: Superior Motion Sensor Using Microwave Doppler Radar
At its core lies a microwave doppler radar sensor that detects human motion with far greater reliability than traditional PIR or IR-based systems. Unlike PIR sensors that depend on heat signatures and often malfunction under sunlight, near heaters, or behind curtains, the microwave radar delivers superior penetration through non-metallic barriers, immunity to heat-induced false triggers, reduced sensitivity to small animals, and omnidirectional detection without requiring a direct line of sight.

PROJECT: Smart EcoBin For Safer Environment
An ultrasonic sensor measures the waste level inside the EcoBin, indicating whether the bin is empty, partially filled, or full. This enables timely collection and prevents overflow. A DHT11 sensor records temperature and humidity, ensuring that conditions inside and around the bin are monitored for improved hygiene and maintenance. An MQ135 air quality sensor detects harmful gases and evaluates overall air quality both within the bin and in its surrounding area. | | |
