 ## Nametag FW for SC7 VectorScope Badge
 
-This code implements a rotating nametag.
+This code implements a wobbling earth. I stole it from true. 
 
 [Install PlatformIO](https://platformio.org/install) to build this firmware.
 
-Edit main.cpp to set your name.
+Edit main.cpp to set your number of pictures.  
+
+## Prepping the photos
+
+Add photos to ```/data``` at 240x240. use the following commands and script with ffmpeg and imagemagick to prep the photos. 
+
+```sh
+    # Source and destination directories
+    src_dir="output"
+    dest_dir="ioutput"
+    #!/bin/bash
+    mkdir src_dir
+    mkdir dest_dir
+
+    ffmpeg -i source_video.avi -vf ./output/out%d.jpg
+
+    # Create the destination directory if it doesn't exist
+    mkdir -p $dest_dir
+
+    # Loop over all JPG files in the source directory
+    i=0
+    cur_count=0
+    for file in $src_dir/*.jpg; do
+        #if (( i % 3 == 0 )); then
+        
+            ((cur_count++))
+            # Construct the destination file name with padding
+            dest_file="$dest_dir/out$(printf "%05d" $cur_count).jpg"
+            # Change the image size and quality and save it to the destination directory
+            # Be careful with size, you WILL need to compile a filesystem to conain your images which will tell you if you're too big
+            # Should stay below 1MB
+            convert $file -quality 50 -resize 240x240 $dest_file
+        #fi
+        #((i++))
+    done
+
+```
+
+## Prepping the PIO
+
+- Copy the images from your above code output to the data directory of this repository
+- In VSCode PIO open the PIO tab and select the BUILD options
+  - Rename your last photo with all 0's because i'm lazy and am not writing a function to automate fetching the list right now
+  - Build the filesystem. If it doesn't error, cool, your photos will fit!
+  - Edit main.cpp with the correct number of photos
+  - Upload the filesystem using PlatformIO
+  - Upload the code to your badge
+  - Make sure the sensors are connected to SCL and SDA on pin 26 and 27
