Touch Screen display box project

 

This project develops a free-standing 'display box' using a Raspberry Pi 5 and the original standard Raspberry Pi 7" touch screen display.

The initial aim of the project was to develop a system to display a series of images, updated on a periodic basis, as a simple 'photo screen'. However, a significant software addition (still evolving!) has been to add a second display option as a 'dashboard' that summarises various sensor readings from other locally running systems. This turns the Touch Screen 'display box' into an IoT local ‘integrating’ hub device, as discussed here, where the other sensor measuring systems periodically 'send' their data to the 'display box' using the 'TCP socket' method across the local meshed WiFi network, with a TCP socket server running continuously in the background on the 'display box' that screens/accepts allowed received inputs.

A custom 3D printed enclosure is used to house the assembly, as shown in the two images above, with a Raspberry Pi 5 as the overall controlling device as shown below. The 3D print designs for the enclosure are available for download from the Prusa web site here.

It should be noted that after a period of use a small redesign of the 3D prints was carried out to increase the number of ventilation slots in the back and top sections of the 'box' so that the fan on the Raspberry Pi's 'Active Cooler' did not have to activate so much and natural convection allowed the Pi to remain at a satisfactory operating temperature for more of the time.

 

The images below show some intermediate stages of the build:
