Who ever looked at an old ventilation device and thought, "Okay, where's the proper card, the history, the parameters, and what the hell is this?" It sounds specific, but that's the vibe. A space for recording, studying, and organizing anemometers, measuring instruments, and other objects related to air movement, mines, industrial history, and technical culture. Here you can collect information about each item, add photos, record the manufacturer, country of origin, year of manufacture, materials, condition, mechanical features, markings, accessories, and provenance. Serious work, but without the feeling of being forced to fill out a form from 1987. For each item, you can save context: from physical characteristics to archival notes. So, not just "I wrote something down," but almost exploratory movements. Calm, structured, a little academic, but without the stuffy inflexibility. The interactive map isn't a simulator for the sake of being a simulator, but a visual way to experience how each device is part of a larger technical history. You can tap, explore, open cards, and perceive the collection as a system. The app is suitable for educational purposes, museum documentation, personal collections, research notes, and learning about the history of ventilation measuring instruments. The main progress is when another object gets its own card. And yes, it sounds incredibly nerdy, but that's precisely why it works. If you're interested in technical artifacts, the history of mines, and industrial heritage, this app will give you the space you need to explore it.
