Milestones

Week 4 (Apr 21 – Apr 27)

• Website (Achieved)

  • Mon, Apr 21: Proposal Update (achieved)
    
    

• PCB (Achieved)

  • Wed, Apr 23: Block Diagram - show layers for power, communication, display, controls, and microcontroller (achieved)

  • Sun, Apr 27: PCB Schematic - selecting components, finding footprints, finishing schematic capture for all systems - IC, power, ESP 32, breakout boards. (achieved)
    
    

• Mini Project (Achieved)

  • Wed, Apr 23: Controlling with Python (achieved)
    
    

• Firmware

  • Test & Report: ESP32 SSID & ESP‑NOW comparison (achieved)

  • Apr 23–May 2: Display text on the screen using Adafruit graphics library  (achieved)

Week 5 (Apr 28 – May 4)

• PCB 

  • Tue, Apr 29: Complete PCB Design - schematic capture (finding components and footprints) and layout (placing components and routing) (achieved)

• Purchasing

  • Wed, Apr 30: Finalize purchasing list for PCB (find all necessary component links on Digikey and deciding on quantity of components) (achieved)

• Firmware

  • Thu, Apr 30: Transmitting & Receiving data between two ESP 32 devices through ESP-NOW and range testing (achieved)

Week 8 (May 19 – May 25)

• PCB

  • May 19: Receive boards and SMT solder components onto all 3 PCBs (achieved)

  • Challenge - soldering regulator and debugging battery supply to PCB

  • May 19: Board bring-up (testing existing firmware works on PCB - OLED can display, messages can be transmitted and received, button inputs to change OLED display work) (achieved)

• Firmware

  • May 25: Create a Pairing Mode to be able to dynamically add other devices as group members (achieved)

• Challenges

OLED interferes with the I2C ports causing trouble with the Serial monitor,  This made us unable to navigate the interface and debug simultaneously. We work around this by disabling OLED and hardcode the environment for testing. 

 Week 9 (May 26 – June 1)

• May 26: Optimize our firmware by reducing message size, fixing UI -> More intuitive (achieved)

• May 26: Practice website walkthrough (achieved)

• May 28: Design and 3D Print first iteration of enclosure (achieved)

• May 29: Finalize enclosure design and 3D print all enclosures (achieved)

• May 30: Finalize firmware for mailbox devices (message storing) (achieved)

• May 30: Video Structure planning (writing script and storyboarding) (achieved)

• June 1: Film Video Demo at woods on campus - scenes for mailbox example, and stranger relaying message example (achieved)

  Week 10 (June 2 – June 8)

• June 2: Editing Video Demo (achieved)

• June 2: Record voice over, extra filming sessions (achieved)

• June 2: Finish text and images on poster (achieved)

• June 3: Finalize website (achieved)
