No it does not appear the the SBHX Google group has folded, there are at least 2 of us!
Here is the SBHX web site address:
https://sbhackerspace.com/
We are open to members 7 days a week for members, from 10 AM to 10 PM.
We do not actually have meetings as such, but there are a lot of people there most Saturdays from 12 PM onwards.
I replied to your email as well, as I am unsure if my SBHX post would post.
Depending on how long ago you came in, we did move a few years ago.
Our current address is:
5782 Thornwood Drive
Goleta, CA 93117
A map is provided on the website, it is basically downtown (or Old Town) Goleta
Any other questions please ask..
Look forward to meeting you.
