Introduction

This summary highlights the resourcefulness in using eWaste for a DIY project, detailing challenges faced and solutions implemented, along with plans for future enhancements. 

• Origin of Components
  • Most components sourced from old, used, and broken electronic devices.
  • LCD panel and Li-Po batteries salvaged from a 5-year-old Acer A500 tablet.
  • LCD driver board obtained from a discarded unbranded monitor.
• Challenges and Solutions
  • LCD Compatibility: Initial mismatch in LVDS interface between tablet LCD and driver board.
    • Replaced blown capacitors on the driver board sourced from discarded electronics.
    • Modified driver board settings using a serial programmer for universal LCD driver boards.
    • Overcame resolution alignment issues with adjustments using online resources.
• Enclosure and Aesthetics
  • Constructed a custom enclosure and stand during the waiting period for the programmer.
  • Painted enclosure to enhance aesthetics and functionality.

Battery and Future Improvements

• Battery Management
  • Unable to utilize original Texas Instruments battery protection circuitry from the tablet.
  • Used single-cell battery protection PCBs on hand, though they have limitations.
    • Slower charging rate and lacking high-temperature cutoff.
• Future Plans (Rev 2)
  • Addressing battery management improvements in the next revision.
    • Implementing better charging speed and incorporating high-temperature cutoff feature.
• Performance
  • Despite limitations, the portable monitor functions excellently considering its minimal cost and repurposed components.
