I suspect one of the greatest barriers to entry for things like Arduino and microprocessor related projects is the fact that you have to come to the table with a certain level of tenacity, stubbornness, and a willingness to tinker even when you meet failure after failure. I picked up a #Watchy from #SQFMI (in part to slake my thirst for a Beepberry which are all sold out), and as detailed as the instructions are, many of them seem to be out of date. I attempted to get it set up in Arduino IDE, and get one of the sample sketches uploaded to the watch, and it failed. And failed in a way that Google is not being helpful.
On the flip side of this, there is this theory that the latest generations of folks didn't have the perspective of this futile yelling in the void over technology that was pieced together from bubble gum and duct tape that most of geek GenX experienced, but these projects are a great way to build it. Mostly by flattening your forehead on your desk.
