The Bodybytes is an implantable WiFi router with software that can be configured and updated by the user. The Pegleg was a previous implant with similar goals, but it ran the now defunct PirateBoxsoftware, could not be updated or configured over-the-air (OTA), and was cobbled together from off-the-shelf development boards like the Raspberry Pi Zero W. The bodybytes is a custom PCB designed from the ground up for performance and usability as an implant. The Vocore2 development board was used as a reference, utilizing the Mediatek MT7628AN.

BodyBytes

Current Design Decisions:

  • A WiFi capable microprocessor manages the operating system (OS)

  • On boot, sensors trigger the device to enter a recovery bootloader

  • A read-only memory sector stores a recovery image

  • A user accessible memory sector is the primary data storage medium for the OS and for user data

  • Bodybytes will use wireless power delivery

    • Capacitive energy storage protects against power inconsistencies

    • A battery powered option is possible but not planned at this time

Current Specifications:

  • WiFi capable microprocessor

  • Operating System
