@cwade12c Yea so generally a group of people go in a building or a space and they essentially cost share the space and investments on tools. Usually other people can join. The best hackerspace I've seen was down in San Diego when I was stationed there. One of the local hams on the 440 repeater I frequented all the time is an EE at Qualcomm and either was a member or was one of the founders of the San Diego one that I checked out. Each hackerspace can vary, it just depends on the space an equipment. If I remember, the one in San Diego had it's standalone building with a garage. The garage had a lift and everything. You could go in there and someone was doing maintenance, swapping an engine or tinkering. Most of them have full electronics labs with scopes and analyzers. If you have one close they are pretty cool. Just remember I said that they vary. It depends on how much money they have for tools or if they get donations. Some have a monthly membership and some have a day rate. Some have classes. Some will reduce the membership cost if you have a skill or knowledge in an area and are willing to dedicate a few hours a week to hosting a class or just being available to help others. So if they have a CNC machine, they may cut someone slack on membership if they have knowledge and are willing to spend 3 hours every Saturday just helping out.
For cost reference, the one in San Diego was I think close to $200/month.

Edit:
You may be more familiar with the term makerspace. It can be essentially the same thing, but the term hackerspace was more before the revolution of arduino, RPIs, and other SBC/MicroControllers.
