A “crazy” DIY idea reveals a very real possibility: setting up a tiny, decentralized satellite ground station in your backyard. With just a Raspberry Pi, a software-defined radio, and some open-source tools, hobbyists can downlink satellite data, contribute to decentralized networks, and earn microcrypto. This isn’t just sci-fi — it’s part of the DePIN movement redefining who controls the infrastructure between space and Earth.
