My experience hosting a bunch of hackers in my basement
I founded the Twin Cities Robotics Group in 1995 so that two colleagues from Cray Research could learn how to solder and program microcontrollers.
After 5 years, the group was going strong meeting once a month at the Science Museum of Minnesota and I wanted more of the community more often.
So I decided to have a kind of open-house once a week for people to get together and get help on their projects.
Someone decided to call it Kilian's Robot Shop Of Horrors. I can't remember why.
My part was to make sure we had a clean organized area to work. That meant that I needed to get the space clean every Friday afternoon before people showed up. I thought it would be unfair to them to make them work in my mess, and as a great side effect, I had to clean up once a week, so I got to work in a much cleaner environment also.
