@f0x Oh cooool, thank you so much for the offer! Once I get a better idea of what I'd like, I just might hit you up for that. The current shape/size is a little ungainly.

And yeah, they're expensive. They said some boards had been 'validated'. I'm not sure if that's an expensive legal process for medical equipment, but maybe that's part of it? I'm also assuming some of the board price goes into funding the library project/development. For my prototype, I'm OK with paying that much, but it's too expensive for me to really consider 'accessible' in something I'd recommend to friends.
