BOM

One goal of this project was to be accessible to lots of people. The total BOM cost using off the shelf components is < $100 (USD):

* (micro)SD card extender

* FPGA [ know of an open source FPGA that works here? Please share! ]

Here's a brief how to:

(1) Connect your (micro)SD card extender to your FPGA pins

(1) b. Map out your pins

(2) Load up the open source SD card emulator onto your FPGA

(3) A driver on the host machine that can do 3 things:

     Read

     Write

     lock / unlock the device

open source release coming soon

Fun fact: Consultants quoted this project between $25k and $250k and anywhere from 3 months - 18 months. No one could guarantee it would work..
