You can volunteer to present or come to listen. Each presenter gets 5 minutes to tell us about a thing they've made (software/robots/etc); then the audience gets 5 minutes to ask questions.
After the meetup, people trickle out. If there wasn't time to ask your question during the 5 minute window, you can catch the speaker then. We usually head to the Old Fashioned for dinner afterwards.
If you're willing to speak, please either post in the comments here or email me at leah.a.hanson at gmail. New speakers are always welcome, and the audience is friendly.
[We expect that if you're presenting a software project, you can show us the code. (This isn't a place to advertise your company's product, for example.) Unfinished/unpolished projects are welcome, but not presentations that are just ideas or plans.]
