  • I’m old enough to remember chemistry sets and they kind of don’t exist any more. Anyway the stuff for making PCB’s overlaps only slightly.

    You probably want to first gain some understanding of the stuff you are trying to do, before messing with expensive dangerous chemicals and all that. I like Ken Shiriff’s reverse engineering blog righto.com and maybe you can follow links from there.

    I’ve always been told through hole plating is quite difficult. Make some single sided boards first, then double sided using vias to connect stuff across the two sides, before pursuing PTH. But I think home PCB’s aren’t really a thing any more either, at least for digital circuits. You can get super cheap board fab from JLPCB or whatever, instead of trying to do fine enough pad pitch for modern tiny SMT parts.






  • I use it to initialize new VPS with my usual setup, but it might be easier to use a container format. I think Ansible itself has become a bit unfashionable since I started using it. I don’t know what is cool instead now. It was Saltstack for a while but idk how long that lasted. Ansible is working mostly ok for me so I’ve stayed with it, til whenever.





  • I think there are still enough v4-only systems out there that you don’t really want to host a mail server on v6. You are right though that it would be nice to be able to get static v6 (or for that matter v4) addresses from home isp’s. Some do offer that of course.

    Another issue can be that the average home internet user has no idea keep even a client system secure. So ISP’s might use NAT and default firewall configurations partly to stop incoming connections on the theory that they are likely to be malicious. On home routers you can usually open ports if you know what you’re doing. I don’t know if that’s even possible on mobile phones.
