Could you build this?
No This is a physical hardware and embedded systems hacking project requiring physical soldering, Linux device tree modification, and custom kernel hacking on proprietary 4G modem chipsets.
What it would actually take: The project requires an MF800/UZ801 Qualcomm-based modem flashed with custom OpenStick Linux, modified Linux kernel drivers, custom device tree source (DTS) configuration for SPI displays and GPIO, and physical wiring/soldering to an Adafruit Sharp display and USB keyboard. Hardware reverse engineering, low-level Linux kernel/device tree driver development, and electronics prototyping skills are mandatory.
