Young creator builds a voice-controlled smart room inspired by Iron Man's Jarvis

A young tech creator has brought a little bit of that science-fiction fantasy into an everyday room with a DIY smart-home device called ‘Jarvis’. It can switch lights on and off, operate fans and even activate a dedicated study mode, all without an internet connection.Ridit Kumawat shared a video on Instagram demonstrating how his compact creation works. Mounted beside his room’s switchboard, the setup allows him to control appliances simply by speaking to it. A command to switch off the lights, for instance, gets an immediate response, while another can turn them back on or activate the fan. But the device does more than respond to individual commands. It also comes with preset room settings, including ‘Study Mode’ and ‘Goodnight’. These allow users to activate a particular arrangement of appliances with a single voice instruction, rather than having to operate each switch separately.Watch the video here: The name ‘Jarvis’ is a particularly familiar one for Marvel fans. In the Iron Man films, JARVIS is the artificial intelligence assistant developed by Tony Stark, helping him manage his technology and control different systems. Kumawat’s project borrows from that fictional idea, bringing a version of voice-controlled assistance into a regular bedroom.What makes the setup particularly interesting, however, is that it does not depend on an internet connection.Unlike popular smart assistants such as Amazon Alexa and Google Home, which typically use cloud-based services to process voice commands, Jarvis is designed to function offline. This means users can control their appliances without having to send their voice commands to external cloud servers.The offline approach also gives the project a different appeal, particularly for people who want basic smart-home convenience without relying on an internet connection.Kumawat has also indicated that he plans to make the complete project and its repository available on GitHub. This would allow technology enthusiasts and DIY enthusiasts to explore how the device was built, understand its working and potentially recreate the setup themselves.From a fictional AI assistant to a working bedroom project, Jarvis is a reminder that sometimes the most interesting technology experiments begin with a simple question: what if your room listened to you?- Ends
