Created by a former SpaceX engineer who worked on Starlink's Dishy terminal, it streams I/Q data over the Pi's MIPI lanes at over 5 Gbps — a novel approach that outperforms USB. A basic kit is available on Crowd Supply for $499. The author tested a prototype with his father (a retired broadcast engineer), finding the hardware impressive despite a rough UI. The device is part of a larger vision for a Moon-scale antenna array capable of EME experiments. ## Full article daily.dev links to this article rather than hosting it.
