DIY Neuro Prosthetic Hand

The DIY Neuroprosthetic Hand Kit is a hands-on electrophysiology project that lets you control a robotic hand using electromyography (EMG) signals from your own muscles.

Designed as an add-on for the Spiker:bit, the basic concept is simple: surface electrodes pick up muscle signals from your forearm, which are processed by the Spiker:bit board and used to actuate a servo motor in the robotic hand. This gives you a real-time demonstration of how neural signals control movement, making it an excellent, beginner-friendly introduction to the world of Brain-Computer Interfaces (BCI) and assistive device engineering!

What's included in the kit: - Foam hand base - Servo motor with actuator arms - Pre-cut balsa wood sheet (for mounting) - String/thread (for the "tendons") - Colored straws (for the "finger pulleys" and "tendon sheaths") - Pencil (used for the servo motor spool)

What you need to supply/purchase separately: - Spiker:bit - micro:bit microcontroller - 2x AA Batteries - Hot glue gun (highly recommended for assembly) - Scissors

Assembly difficulty: Skill Level: Beginner / Easy. Perfect for classroom environments or weekend Maker projects. Estimated Time: 1 to 2 hours. The build relies on simple hot glue and string-tension mechanics. Programming the micro:bit is a breeze with block-based coding via MakeCode (Python and JavaScript are also supported for more advanced users).
