> This modular phone companion (like MagSat v0.1) could shine in:
> 
> - Travel: Stack extra batteries for off-grid adventures.
> - Security: Kali-compatible WiFi for ethical hacking or network testing.
> - Productivity: Add e-ink screens for low-power note-taking.
> - Health: Modules with sensors for fitness tracking or air quality monitoring.
> - Customization: Open platform lets users build niche tools, like drone controllers or mini labs.

> The post discusses MagSat v0.1, a prototype by Ivan Kuleshov (Merocle), Head of Hardware at JetBrains. It's a proof-of-concept modular companion for phones, based on the open-source MinCab carrier board for Raspberry Pi CM4. The device attaches (likely magnetically) to a phone, enabling stackable modules like extra batteries or advanced WiFi compatible with Kali Linux. Video shows assembly and a terminal interface running on the phone. He'll continue development as an open platform in 2026.

Update:

> I didn't expect such a response to this form factor, because, to be honest, the use case doesn't seem obvious at first glance. Thank you all very much for your ideas! 
I think it will be an open platform, just like the original device on which the PoC is based https://uplab.pro/2021/10/mincab/
