Introduction: LunchTop: a Raspberry Pi Lunch Box Laptop

Picture of LunchTop: a Raspberry Pi Lunch Box Laptop

This is a fun and fairly easy project to build a portable Raspberry Pi computer that fits right into a standard lunch box. This is a good project to start with since it doesn't require much technical knowledge. All you have to do is purchase the parts necessary to build the LunchTop, plug everything in and secure it to the inside of the lunch box.

I have listed all the parts used in this project with cost and links to purchase the items, but you can feel free to look around for alternative parts.

Step 2: Modify the LCD Case

I needed to modify the Touchscreen LCD case because the one micro USB cable that attaches to the monitor board needs to come out of the side of the enclosure so that it can plug into the Raspberry Pi. To do this you will need a drill and drill bits. Start with the smallest drill bit and work your way up to 3/8" bit. This will be big enough so the micro USB cable can be feed through the enclosure.

Step 3: Assembly of the LunchTop

The first step to assembling the LunchTop is to completely assemble the Raspberry Pi, then attach it to the LCD screen and finally secure it with the LCD cover.

Once that is complete your next step is to attach all the parts to the lunchbox and hook up all the cables. I used Velcro strips to secure the battery, Raspberry Pi, game controller and keyboard. This allows me to easily disconnect everything so I can use the Raspberry Pi on other projects (e.g. breadboard and sensor kits).

great job. I would like to see more details on the build though. How long does the battery last?

Depends on how much you use it daily but I usually get 2-3 days out of it between charges.
