I got pretty good at "Makers Competitions" in my University years, to the point where my technical peak wasn't when winning a NASA competition, but ~2 years later when we released a technical product within a weekend in another competition.

I remember wrapping up the competition, winning all the prices we could win except one (1st place, and "best of" for 3 out of 4 categories), and the feeling that we had demolished the competition all around and that felt somehow a bit unfair for the rest. That was the last time I participated in a competition of this kind.

How did we do it? I had the network of contacts already (co-created a Maker group at my University) so I could literally hand-pick a team of 5 with the best maker in each sector; I called my previous co-winner who is great at tech presentations, and called the best designer+3D artist, the best App programmer, the best electronics person I knew, (and me). I got a stomach infection and spent a third of the competition in the toilet, but I ended up doing mainly programming and organizing: 1-2 hours to decide on the theme and solution, then split the work efficiently, and then let each person work on their own thing while continuously checking for sync between them. We ended up with a product and UI that seemed like a commercial product.
