you want private use only or want to setup public small relay for npub? what existing hardware u have ? pc / pi / old andriod phone ?
Discussion
I've got an old laptop I can repurpose. I would be willing to invest some fiat into an additional piece of hardware for another one. I mostly want to experiment right now but ultimate goal would be paid community relay and a paid public and maybe a free public too.
just for relay no need buy anything at all
1GB RAM 2CPU 50GB+ HDD will do
best options since u need learn are
1. windows + python + relay
2. install ubuntu 20.04 +python
3. install start9 OS (need more CPU RAM)
search internet n learn slowly
LAN relay ws://ip:port
ws://captjwedewdawewdwawdwdwdwd.onion
learn tor install first
for above no need any domain name or ssl
below get clearnet+dns type relay
learn ngix+certbot
plus get get relay.subdomain.io ->ur IP
IPv4 or IPv6 <-- INBOUND any port OPEN(check with ISP)
u can pick from 1 2 3 options which u feel easy or jump one to another if stuck. no 2 learning u can DIY useful for cli - 1 or 3 are mostly GUI
