Project Intro

A connected light designed as a complete product.

Smart Lamp began as a gift for my high-school friends and teachers before I moved to the United States. Building on work from Dr. Lintao Tang’s lab at Tsinghua University, I designed the hardware, firmware, and enclosure as one system.

Context

I planned to build this project as a gift for my high-school friends and teachers before I moved to the United States for my Bachelor’s degree. Unfortunately, I could not produce enough lamps because of time limitations.

Features

The lamp has the following features:

  • The lamp can be controlled through a capacitive touch interface and Bluetooth.
  • The capacitive touch interface has one button that supports on/off and dimming control.
  • Users can connect to the lamp with Bluetooth to control dimming, color, and on/off functions.
  • The lamp supports wireless charging and charging through Micro-USB.
  • The lamp integrates a battery management system for three-phase charging of an 18650 battery.
  • An MSP430 MCU achieves low power consumption.

Development

I designed the product from scratch, including the hardware, firmware, and industrial design.

The project followed these development phases:

  • Planning the functionality
  • Developing the industrial design, planning dimensions, and creating 3D models
  • Designing the hardware systems
  • Choosing components
  • Designing, manufacturing, and assembling the PCBs
  • Developing the firmware
