1. Add power through USB battery (remember to push the button)
2. Give Linux about ~60 seconds to start up.
3. Join the "Zundtastic" wifi network from any nearby computer. 
4. Open a terminal and log into the tool: `ssh pi@192.168.4.1`
5. Start the webcam server: `/usr/local/bin/mjpg_streamer -i "/usr/local/lib/mjpg-streamer/input_uvc.so -n -f 15 -r 1920x1080" -o "/usr/local/lib/mjpg-streamer/output_http.so -p 8080 -w /usr/local/www"`
6. Open a web browser and go to `http://192.168.4.1:8080/target.html` to view the stream.
7. When you are ready to shut down the scope, from the terminal run `sudo shutdown now`
8. Unplug the battery.

## TODO

1. Make a startup service that starts the webcam server.  Need to issue the shutdown command via the webpage to avoid potential corruption of SD card.
2. Would be great to adjust field of view without disassembling the scope.  Maybe as simple as an access hole for adjusting knob.
