Hmm this is super tempting. I’ve been wanting to make a digital wall clock + purple/air now AQI near my patio door. How does crowd supply work? Is it similar to Kickstarter or do they charge only on delivery?
But, be careful and do your diligence on products. Sometimes it's just junk marketed as something else. Personal example: Programmable modules with screens, long battery life--turns out they were just the screen/board/cpu for some unsuccessful china smart watches.
