Yesterday I finished the build, with mounting standoffs drilled through the case. I also mounted the magnet for the LCD activation into the base using some woodworking tools to recess it to prevent it from being pried off. You can see the Sensor glued on to the lid on the left, and to the right of the sensor I have hot-glued the USB connector for the screen so I can charge it and load new videos.

Here are the pictures of the final project!

Also some of my son trying it out for the first time!
