Well there are lots of tutorials out there. I can recommend nostr:npub1rxysxnjkhrmqd3ey73dp9n5y5yvyzcs64acc9g0k2epcpwwyya4spvhnp8 for that 😉

But in reality it’s really not that hard ( I know what I’m talking about lol)

There are loads of options out there if you want to run your own node:

nostr:npub1aghreq2dpz3h3799hrawev5gf5zc2kt4ch9ykhp9utt0jd3gdu2qtlmhct with or without a raspberry pi 4

nostr:npub126ntw5mnermmj0znhjhgdk8lh2af72sm8qfzq48umdlnhaj9kuns3le9ll

Those are probably the most common ones. You can do lots of stuff with these devices besides running a node too.

There’s also the raspiblitz, but I don’t know much about that.

The cheapest thing to do would be installing nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 on your phone and use their embedded node, I’m not familiar with that, but on their website there’s lots of information 😌

For instance: this is what my node looks like, a raspberry pi 4 (in a housing I bought online) and besides that there’s a 2TB ssd

then maybe the Cloud version is the better option for you.

or you check the guides and learn how to run it yourself.
