I’m not sure what the “pre-judging” criteria is, so I feel my chances are as good as anyone else. They could be weighting “originality” higher or lower than “feasibility”. It would be nice to know… I have a lot of speculation on Hackathons like this, but haven’t analyzed what tends to make successful entrants.
I presume that making extensive (deep) and creativity (unique) use of the sponsor’s technology is of prime importance. There are thousands of obvious and not-so-obvious water saving ideas for which using ARTIK is very suboptimal. That, to me, would eliminate a lot of entrants who don’t phrase their application summary appropriately.
