Smart Box Ball Based on ESP8266

Smart Box Ball

This is an advanced version of the classic elastic ball game (Box Ball), designed to improve coordination, reaction speed, and agility. Unlike a standard ball, our device is equipped with smart electronics based on the ESP8266 microcontroller (NodeMCU). It can track the number of hits, measure hit force, and enable online competition via the bitball.club website with other users who have similar devices. Players can also track their progress in real-time.

You can build the device yourself or ask us to do it for you. To order a ready-made device, contact us via Telegram, Skype, or Discord.

Key Features

  • Hit Tracking: The device uses built-in sensors to accurately record every hit on the ball.
  • Hit Force Calculation: The device analyzes sensor data to measure hit force, adding a competitive edge.
  • Wi-Fi Connectivity: The device connects to Wi-Fi, allowing players to save training results in the cloud and participate in online tournaments.
  • Flexible Training Settings: Users can set training durations and other parameters, tailoring the device to personal goals.
  • Feedback System: Sound or light alerts help signal training completion or motivate users to improve their results.
  • Online Competitions: Players can compete in real-time with others via bitball.club, compare results, and elevate their training.

Benefits

  • Interactivity: Training becomes more engaging and interactive thanks to automatic counting, hit force measurement, and instant feedback.
  • Real-Time Competitions: Users can compete with others globally, making training even more exciting.

Our smart Box Ball is not just an elastic ball—it’s a high-tech training device that lets you set goals, track progress, measure hit force, and reach new heights in coordination and reaction training.

This backing is essential for the correct operation of the weight sensor; without it, false triggers may occur. It’s important that the internal part of the scale does not come into contact with the forehead or any other surfaces.
