Our project creates a fast, easy, and expandable system that allows a CEED employee to easily sign out, sign in, and keep track of 3D printers and their corresponding SD Cards. In addition our system allows the easy collection of user feedback.
Our product is based off a Raspberry Pi 4 and employs the use of a RPI Camera. The camera runs custom software that allows the Pi to process and relay information read from QR codes. The QR codes are designed to be printed and attached to an SD card which corresponds to a 3D printer in the makerspace. A CEED employee will have access to both the RPI as well as a dashboard UI. The UI allows for the staff member to easily scan a QR Code, signing it out, or returning it if already signed out. The UI also displays the number of active printers, and the time in which the printer was signed out. The Pi itself also stores a log of active printers, as well as a list of all QR Codes scanned as well as the time the code was scanned in, and out. What makes our project special is the easily expandability, if the makerspace wishes to add more printers, not modification needs to be made to RPI, its software or the Dashboard UI. Simply by printing more QR codes and assigning them a unique value that corresponds to a 3D printer, the scanner will automatically sense the new QR code, and add it to the system without any user modification required.
