MOD. image slideshow server

An image slideshow server written in Ruby on Rails.

TODO:

• Create Image model.
• Create POST API for accepting images.
• Fix Action Cable to update homepage with new images created.
• Create slideshow on homepage of 30 most recent images.
• Make homepage slideshow fullscreen & fit the images to it.

Run the server

$ bundle install $ rake db:create $ rake db:migrate $ rails s -b 0.0.0.0

Create a config/application.yml file adding:

app_site_title: "MOD. Draw Your Pain"
projector_width: "1920"
projector_height: "1200"
deep_dream_server: "http://localhost:5000"
image_text_overlay_font_path: "/path/to/font.ttf"

Slideshow of approved images

After approving images from the /images screen, and tapping the Update slideshow button, the approved images will be saved to /public/slideshow/.

To get these images to display fullscreen, auto-update when new images appear from Rails, and auto-start when the computer starts, I wrote these bash scripts to run at boot:

Generate slideshow by creating an image in a folder every 5 seconds*

#!/bin/bash
cd /home/mod/Sites/mod-image-server/public/slideshow
while true ; do for i in $(find -type f  | sort -r) ; do cp "$i" ~/slideshow.png ; echo $i ; sleep 5 ; done ; done

Show image full-screen in Ubuntu using eog

#!/bin/bash
eog -f ~/slideshow.png

Start the Rails server on boot

#!/bin/bash -x
source /etc/profile
cd /home/mod/Sites/mod-image-server
rails s -b 0.0.0.0

I then used Ubuntu’s GUI System > Preferences > Startup Applications to add these scripts to run on startup.
