Should you buy an extra router for your DIY projects?
If youre putting together a DIY project that needs a network connection, like a NAS or a home media server, plugging into your main network is the end goal, but could cause some problems if youre still experimenting. DIY projects by their very nature can result in a lot of trial and error, and if youve got other members of your home using your home network, they might not think that restarting the router or needing to assign custom IPs to every new device is quite as interesting as you do. For the most part, you won't need another router for DIY projects, but if it involves networking, it's not a bad idea to do your testing on a separate router.
