This project is awesome, but I'd be worried about my hand brushing up against all that lead every day for years. Or am I being too paranoid? In any case, easily solved with some casting epoxy.

#12 I want to work on projects that do good.
I don’t want to work on projects regarding surveilance
or the weaking of existing cryptosystems.
Way to go Connor!Re: Show HN: A secure, open source U2F token you can make with $4.5 worth of parts

#15My barrier to entry with a lot of DIY hardware projects was an incorrect assumption that it was difficult/expensive to get PCBs made. Looking into this, I found the blog of the guy running this project and he had some experience with various cheap PCB vendors, with stencils going as low as $18.

In addition to the vendors you mention via that link, OSH Park[1] is great option for hobbyists (or very small-volume production). This is the same source listed in OP. It's a board pooling group that puts many small-run orders on the same panel to economize on setup costs. OSH Park uses high-quality US manufacturers to produce the boards (with tight tolerances, silkscreen, soldermask, gold-flashed pads, etc.) I beli…

#16Open source made from parts seems like it would be very much under your own control. But it is also... bespoke. Which raises a different threat model, doesn't it?

This must be awesome for training and university settings, to have such low cost options for learning the craft. Is it used much by startups / is it bringing down the barrier to entry that much?
My last company did care about turn time but also wanted affordable boards. They used PCB-Pool: http://www.pcb-pool.com/ppus/index.html

#18This is neat! Is there also source for the firmware that runs on the secure element?
No it is purely a hardware peripheral that just has configuration options. http://www.atmel.com/Images/Atmel-8923S-CryptoAuth-ATECC508A...
Is there a similar chip with Curve25519?
