Hardware Design and 3D Modeling
Description
A collaborative ECEN 361 embedded systems project with teammates Jared Whiteman, Aidan Pratt, and Ryan Christensen. I led the PCB and 3D printed parts design, while firmware work and the acrylic case was contributed by my team.
Project Overview
This project involved designing a lighting console PCB with USB, Ethernet, and DMX connectivity, 8 motorized faders, 16 switches with RGB LEDs, 16 potentiometers, and a built in 12V power supply.
The focus of this page is on the hardware design and features. Images below include PCB design layouts, and modifications addressing power and signal issues on the first revision.
Features
- USB and Ethernet interface
- 8 motorized faders driven by STM32L4 (uses 16 PWM lines)
- 16 switches and 16 potentiometers
- DMX connectivity for stage lighting
- RGB LED indicators under switches
- 12V power input
- 3D printed parts for sliders and PCB stands
Challenges & Setbacks
- The first STM32 became damaged after an unanticipated latchup.
- Ethernet termination resistors missing and center taps misconnected
- Polarity reversed on barrel jack wiring
- Designing dense board with limited space
Team Video
Video demonstration of the lighting console's features, including fader movement, RGB LED feedback, switches, and connectivity.
