I have run Lightning-nodes on Raspberry Pi in the past. I would not recommend it at all. Listen to NVK.
Raspberry Pi was once upon a time relatively cheap. Now it’s expensive compared:
- to hardware that is a lot better hardware and chips from other vendors than Broadcom
- which is open source, instead of close source - with better redundancy (with Proxmox)
- for a cheaper price
Raspberry Pi has its use cases. Lightning nodes, with real hard money, with absolute scarcity, on a hot wallet, is not one of them.
From the other side, Seedsigner does use Raspberry Pi. But it’s not a Lightning node.
“A custom linux based operating system built to manage software running on airgapped Bitcoin signing device. SeedSigner is both the project name and application running on airgapped hardware. This custom operating system, like all operating systems, manages the hardware resources and provides them to the application code. It's currently designed to run on common Raspberry Pi hardware with accessories. The goal of SeedSigner OS is to provide an easy, fast, and secure way to build microSD card image to securely run SeedSigner code.”
