:: LCD / Touch Monitor ::

Current monitor works but is too expensive, has a plastic touch surface (which scratches) and is not bright enough @ full sun. Power supply is also inefficient.

Goal to build Monitor Enclosure to simplify and reduce cost

Steps:

  • Select LCD panel (daylight brightness

  • Design and fabricate enclosure

  • Electronics

    • Power supply

    • Auto-dim (reduce brightness and power consumption at night)

  • Waterproof enclosure

  • Touch surface high durability (glass front)

 

Note, this could be combined with the CommsBox below, to create a single unit, like:

CommsBox v3 (formerly Top Box)

The CommsBox contains all the added bits that make a user terminal:

  • USB Hub

  • Webcam

  • Audio amplifier w/ volume control

  • Headphone port

  • Speakers

  • Microphone

  • On/Off switch

  • Power breakout (12v to audio amp, hub, monitor)

  • USB to keyboard / touchpad / touch / user device

Version 2 of the Comms Box is good, but needs some improvements still:

  • Regulated power supply

  • Power protection (fuse, relay)

  • Component placement / wiring plan

There is the possibility of creating a custom PCB to provide whats needed here, including a usb3-pcie bridge + low power GPU chip… this would be bigger project, but huge for Project Hello World (and might be broadly applicable for other education projects using Linux MultiSeat).

NEW - Hello Hub Health System / Sensors

  • Primarily, power sensors

    • Voltage @ Battery

    • Voltage @ PV

    • Current FROM PV

    • Current TO System

  • Integrated to Hello Hub system via usb / 1-wire, or other, or

  • Standalone board w/ gsm (totally independent)
