Because maker challenges are a great way to be a part of the maker community I've got this page dedicated to challenges. I try to list all the maker challenges that I know of. If you know of a challenge I've missed, then let me know and I will add it.
check here for a list of maker events that are happening. It's still a work in progress but if you know of a good event then let me know and I will add it.
