AI-Based Hand Tracking for Robotic Arm Control
In this project, we show how to control a robotic arm servo using real-time hand tracking powered by AI image processing. We use MediaPipe for fast hand detection, a web browser for processing camera input, and an IndusBoard Coin to translate hand movement into servo motion. The result is a simple but powerful human-machine interface […]
Satellite Tracker Watch
Tracking satellites and understanding their real-time position usually requires bulky equipment, software-heavy tools, or online platforms. For students, hobbyists, and enthusiasts, there is a lack of portable, standalone devices that can provide live satellite data in an intuitive and accessible way—especially in a compact, wearable form. Key Features Applications This Satellite Tracker project showcases how […]
Smallest Programmable Indus Phone Design (Part 2)
Building an ultra-compact phone is not just a hardware challenge, it requires seamless integration of the user interface with real phone functionalities. While the initial IndusPhone design established the UI and validated GSM communication, the lack of integrated calling logic, app handling, and background task management limited its usability as a complete phone system. Part […]
SOS Device For Emergency Alerts
Children, elderly individuals, medical patients, and women often face situations where they need immediate help but cannot safely or discreetly use a smartphone. Dialling numbers or navigating a phone interface during emergencies can be slow, stressful, or even impossible, increasing the risk in critical moments. A compact DIY SOS alert device, small enough to be […]
Smallest Portable Ammeter and Energy Monitor Device
Conventional ammeters and energy meters are often bulky, require multiple probes, and lack portability for quick field measurements. Multimeters, while versatile, are not optimized for continuous energy monitoring, real-time frequency measurement, or compact embedded applications. There is a clear need for a smaller, smarter, and more intuitive measurement device without compromising functionality. A coin-sized portable […]
World’s Smallest Programmable Indus Phone Design (Part 3)
Earlier versions of the DIY IndusPhone demonstrated the feasibility of building an ultra-compact touchscreen phone, but they relied on a 2G GSM module and ran individual functions separately. With 2G networks becoming obsolete and increasing system complexity, there was a need for modern network compatibility, better task management, and a unified software architecture that could […]
Tesla Coil and Wireless Power Bulb
Demonstrating high-voltage generation and wireless power transfer concepts can be complex due to the need for clear circuit design, component selection, and safe testing methods. Beginners often find it difficult to understand how resonance and electromagnetic induction work in practical high-frequency systems. This article presents the design and construction of a mini Tesla coil that […]
IndusScope – Portable Smallest IoT Oscilloscope
Conventional oscilloscopes are bulky, heavy, and not always practical for working with microelectronics or compact setups. Carrying a full-sized oscilloscope for quick signal inspection, basic waveform visualization, or field diagnostics can be inconvenient and inefficient. InduScope is a compact, IoT-enabled oscilloscope built using the IndusBoard Coin. It leverages the ESP32-S2’s ADC capabilities and a simple […]
IndusVoltmeter – Smallest Wireless Voltmeter
Traditional voltmeters can be bulky and inconvenient for quick diagnostics, especially during on-site work or rapid prototyping. There is a need for a compact, portable solution that can measure both low and higher DC voltages while also allowing remote, real-time monitoring without being physically close to the device. This project introduces IndusVoltmeter, a compact wireless […]
AI-Powered Gesture Detection Using Edge Impulse
Gesture recognition on compact embedded devices is challenging due to limited processing power, memory, and storage. Most AI-based gesture detection systems rely on cloud processing or high-end hardware, making them unsuitable for real-time, low-power edge applications like wearables and smart devices. This project demonstrates AI-powered gesture recognition running entirely on an edge device using the […]
