Even if you don't know what an Arduino board actually is (in which case, check out this overview), chances are you've excitedly shared a link with your friends about something powered by Arduino. This wondrous open-source electronics prototyping platform is pretty much everywhere these days, and if Digispark becomes the next big thing (no irony intended here, I swear), it's going to be even more prevalent soon.
In a nutshell, the Digispark is the "little brother" to the Arduino line of development boards – a pint-sized (it's the size of a 5p), Arduino-compatible open-source USB development and production platform that is cheap enough to forget in a friend's a house.
Erik Kettenburg, the person responsible for the Digispark, currently has a Kickstarter campaign going to bring Digispark to life. Needless to say, he got more than he asked for. With 27 days left to spare, the Digispark Kickstarter campaign boasts of approximately $45,000 in funding (Eric asked for only $5000).
So, why are we telling you about the Digispark when Erik is no longer in desperate need for cash? Easy. Because this is probably the best time to get a few Digisparks of your own--early adopters will be some of the first people in the world to receive a Digispark.
