🛰️Satellite modem demo on Flipper One — an emergency pager
Experimenting with satellite connectivity on Flipper One. The video shows an emergency SOS pager that sends your geolocation so you can be evacuated from a zombie apocalypse when there is no mobile coverage.
NTN (Non-Terrestrial Network) is a 3GPP standard in the LTE/5G family. It uses a regular SIM card and is supported by many modern smartphones and smartwatches. NTN is extremely slow and is billed per byte (!), but this is okay when you need to send tiny amounts of data: telemetry or short messages like “I’m alive, heart rate 80 bpm.”
In this demo, we use a Blues @buildwithblues NOTE-NGBLWX module that connects to a geostationary satellite on the Skylo @SkyloTech network and transmits data to a Blues NoteHub server.
We’re planning to develop a Flipper One IoT module that can serve as a backup communication channel for outdoor use or as an emergency gateway for alarm and monitoring IoT systems.
PostgreSQL 19 introduces graph-style queries.
Instead of manually connecting table after table with joins, you can describe the path through your data:
customer → bought → product ← bought ← similar customer → follows → brand
Useful for recommendations, access control, fraud detection, knowledge graphs, and AI context.
