Introduction

This document outlines the development process of a modular kinetic sculpture featuring multiple balls moving up and down. The installation inspires the design in the BMW Art Museum. The goal is to create a scalable system using stepper motors, I2C communication, and a spool-based winding mechanism.

Project Overview

Mechaism: The system utilizes a spool-based winding mechanism driven by stepper motors.

Electronics: Each module is equipped with an ATtiny1614-based subordinate PCB, paired with DRV8825 stepper drivers.

Control: Modules communicate with a central controller via the I2C protocol.

Material Choices: Structural components are primarily laser-cut from acrylic. 3D printing with PLA or PETG is reserved for parts unsuitable for laser cutting, optimizing fabrication efficiency.

Scalability: The design supports scalability from an initial single module up to 64 modules.

Road map

1. Phase 1 (2 Weeks) : One working prototype module
2. Phase 2 (2 Weeks) : One scalable module ( Connector, Communication, Form, etc )
3. Phase 3 (2 Weeks) : 10 Modules -Test
4. Phase 4 (3 Weeks) : 64 Modules - BOM , Approvals , Fabrication and assembly
