Ask HN: Doing my first hackathon as a non-developer

Hey HN, I'm doing my first hackathon this weekend in hope to build a team interested in open science. I'm a neuroscientist with a strong IT background, but I haven't built an app since VB6 back in 2001.

I initially pitched my idea at a pre-meeting and met a bunch of people who were interested in my idea (omnisci.org).

I'd like to hear from the hackers here...

1. Describe your best experience with an entrepreneur who needed help building a concept.

2.When speaking with a non-developer about their concept, what are a few things that you can't stand?

Any input is appreciated!
