LabCraft

LabCraft brings the management of a FabLab, a making and coworking space, into one desktop application: clients, staff, equipment, projects, rooms and workshops.

A second-year academic project built as a team, each member owning a module. I took the Clients module end to end, room management and the Arduino integration that monitors room temperature.

Clients

• Complete records: creation with input checks and a required photo, two-step editing (load, then save), deletion.
• List with photos right in the table, search by name and sorting by sign-up date.
• PDF export of a client record and statistics as an animated chart.
• Welcome e-mail sent automatically to every new client.
• Image scanner: a photo becomes a high-contrast black-and-white document.

Rooms and temperature

• Rooms: capacity, price per day, status and maximum allowed temperature.
• Arduino monitoring: the real temperature is compared with the room’s maximum, with an alert to start the fan.

• C++11 and Qt 5: screens designed in Qt Designer, page navigation with a QStackedWidget.
• Layered, MVC-inspired architecture: .ui views, controllers (MainWindow, SecDialog), and Client and Salle domain classes that own the CRUD.
• Oracle through ODBC (Qt SQL) with prepared statements throughout, against SQL injection; photos stored as BLOBs and shown through a custom SQL model.
• Secure SMTP client written by hand on QSslSocket, as a state machine (EHLO, TLS, AUTH, MAIL, DATA).
• Arduino Uno detected automatically from its USB identifiers, read through Qt SerialPort (9600 baud), with outliers filtered out.
• Qt Charts for statistics, Qt PrintSupport for PDFs.
