37% rural youth sans Internet access: Study
Over the last few months, the activism against Facebook’s free internet in India has been called “elitist” and “self-righteous.” An opinion piece in The New York Times, for instance, called the opposition “elite Indian condemnation of internet for the poor.”
Most voices that have come out in criticism of Free Basics—which provides free but limited internet access to Reliance Communications’ subscribers in India—were of venture capitalists and technology entrepreneurs, who are unlikely to be the direct beneficiaries of the service.
Now, Khabar Lahariya— a weekly newspaper run and published by women in multiple languages—has released a video and an audio clip that give some insights into how some rural women view the service. And, according to them, Free Basics is a harmless but ultimately unimpressive product.

Balanset-1A: Advanced Portable Balancer & Vibration Analyzer
Professional Dynamic Balancing Solution
Balanset-1A constitutes an advanced solution for vibration correction of rotors in their own bearings, developed by Estonian company Vibromera OU. The device delivers professional equipment balancing at €1,751, which is 3-10 times more affordable than traditional vibration analyzers while maintaining superior measurement accuracy. The system enables field balancing directly at the equipment’s operational location without requiring disassembly, which is critically important for reducing production downtime.
About the Manufacturer
Vibromera OU is an Estonian company specializing in the creation and production of instruments for technical diagnostics of industrial equipment. The company is registered in Estonia (registration number 14317077) and has branches in Portugal.

Technical Specifications
Measurement Parameters
Balanset-1A ensures precise measurements using a two-channel vibration analysis system. The device measures RMS vibration velocity in the range of 0-80 mm/s with an accuracy of ±(0.1 + 0.1?Vi) mm/s. The operating frequency range is 5-550 Hz with optional extension to 1000 Hz. The system supports rotational speed measurement from 250 to 90,000 RPM with phase angle determination accuracy of ±1 degree.
Working Principle
The device uses phase-sensitive vibration measurement technology with MEMS accelerometers ADXL335 and laser tachometry. Two single-axis accelerometers measure mechanical oscillations proportional to acceleration, while a laser tachometer generates pulse signals for calculating RPM and phase angle. Digital signal processing includes FFT analysis for frequency analysis and proprietary algorithms for automatic calculation of balancing masses.
Full Kit Contents
The standard Balanset-1A delivery includes:
Measurement unit with USB interface – main module with integrated preamplifiers, integrators, and ADC
2 vibration sensors (accelerometers) with 4m cables (alternatively 10m)
Optical sensor (laser tachometer) with 50-500mm measuring distance
Magnetic stand for sensor mounting
Electronic scales for precise measurement of corrective masses
Software for Windows 7-11 (32/64-bit)
Plastic transport case
Complete set of cables and documentation
Operating Capabilities
Vibrometer Mode
Balanset-1A operates as a complete vibration analyzer with capabilities for measuring overall vibration level, FFT spectrum analysis up to 1000 Hz, calculating amplitude and phase of the fundamental frequency (1x), and continuous data recording. The system provides display of time signals and spectral analysis for equipment condition diagnostics.
Balancing Mode
The device supports one-plane (static) and dual-plane (dynamic) balancing with automatic calculation of correction masses and their installation angles. The unique influence coefficient saving function permits considerable acceleration of follow-up balancing of same-type equipment. A dedicated grinding wheel balancing mode uses the three-correction-weight method.
Software
The intuitive program interface offers step-by-step guidance through the balancing process, making the device accessible to personnel without special training. Key functions include:
Automatic tolerance calculation per ISO 1940
Polar diagrams for imbalance visualization
Result archiving with report generation capability
Metric and imperial system support
Multilingual interface (English, German, French, Polish, Russian)
Application Areas and Equipment Types
Industrial Equipment
Balanset-1A is successfully applied for balancing fans (centrifugal, axial), pumps (hydraulic, centrifugal), turbines (steam, gas), centrifuges, compressors, and electric motors. In production facilities, the device is used for balancing grinding wheels, machine spindles, and drive shafts.
Agricultural Machinery
The device offers exceptional value for agriculture, where continuous operation during season is critically important. Balanset-1A is employed for balancing combine threshing drums, shredders, mulchers, mowers, and augers. The possibility to balance on-site without equipment disassembly allows preventing costly downtime during critical harvest periods.
Specialized Equipment
The device is successfully used for balancing crushers of various types, turbochargers, drone propellers, and other high-speed equipment. The RPM frequency range from 250 to 90,000 RPM covers practically all types of industrial equipment.
Benefits Over Competitors
Economic Value
At a price of €1,751, Balanset-1A delivers the functionality of devices costing €10,000-25,000. The investment pays for itself after preventing just 2-3 bearing failures. Savings on outsourced balancing specialist services amounts to thousands of euros annually.
Ease of Use
Unlike complicated vibration analyzers requiring months of training, mastering Balanset-1A takes 3-4 hours. The step-by-step guide in the software allows professional balancing by personnel without specialized vibration diagnostics training.
Mobility and Autonomy
The complete kit weighs only 4 kg, with power supplied through the laptop’s USB port. This permits balancing in field conditions, at remote sites, and in inaccessible locations without separate power supply.
Universal Application
One device is appropriate for balancing the widest spectrum of equipment – from small electric motors to large industrial fans and turbines. Support for one and two-plane balancing covers all typical tasks.
Real Application Results
Drone Propeller Balancing
A user achieved vibration reduction from 0.74 mm/s to 0.014 mm/s – a 50-fold improvement. This demonstrates the remarkable accuracy of the device even on small rotors.
Shopping Center Ventilation Systems
Engineers successfully balanced radial fans, achieving lower energy consumption, eliminated excessive noise, and prolonged equipment lifespan. Energy savings paid for the device cost within several months.
Agricultural Equipment
Farmers note that Balanset-1A has become an vital tool preventing costly breakdowns during peak season. Lower vibration of threshing drums led to decreased fuel consumption and bearing wear.
