Up until now, this has been mostly restricted to urban locations. In this instructable, I am going to attempt to expand this project beyond city limits by showing everyone how to embed USB drives in natural fixtures such as trees and rocks.
Step 1: Materials
USB flash drive
Drill bit set
Screw driver, or other tool to pry open the flash drive
Step 2: Remove the Housing of the USB Drive
Step 3: Wrap the USB Drive in Plumber's Tape
Step 4: Select a Dead Tree or Stump as a Dead Drop Location
Step 5: Drill Holes in the Trunk to Make Room for Your USB Drive
If you want to make a smaller imprint on the surface and make the end product look a little cleaner, you can drill a series of smaller holes in a line to make a slot. Each hole should be the same thickness as the USB drive (about 1/4 inch). Then you can finish the shaping with a knife or file.
Be sure to drill your hole is a part of the tree that is solid and free from rot.
Step 6: Apply the Wood Glue and Insert the USB Drive
Once the glue dries, you have a USB deaddrop site out in nature. If you wish to prolong the life of the drive, you can put a cap on it to at least partially protect it from the weather.
Step 7: Finished Dead Drop Site
I also decided to also load a copy of "The Giving Tree" by Shel Silverstein onto the flash drive (Yes, I got the idea from this xkcd comic by Randall Munroe).
To document the dead drop location, it helps if you take three pictures of the location (up close medium and far away). This makes it easier for others to find your dead drop.
