I think he was always planning on getting them properly made by machine, that's what the kickstarter is for (the upfront cost).
His other advantage is being Chinese, and therefore not having to bother with any of the expensive wireless approval process that's normally required for this sort of thing.
Theoretically, no. However, if he makes a bunch of devices and posts them to the US, in practice the FCC are never going to be able to enforce the requirements on him.
Looks like he was planning on making about 300 units by hand. Now he has to make nearly 700 and it hasn't even been a week. 8 weeks left to go.
Good luck. May the maker gods smile upon you.
