The robot arm is expensive because it needs precision hardware (backlash free bearings/gearing).

Your idea also requires precision hardware to move the sphere.

Thanks for writing this, the post is super helpful! I didn't see anything about the circuit design/iteration process. Would be great to hear what software was used to design the circuit (if any) and how that eventually translates to mass production.

Cool! I had an idea for something like this but instead of having each build be it's own lambda event, I wanted to make each individual test it's own lambda event. The goal is to have the build time for a complex project boil down to the time it takes to setup + run the longest test.

Yes, it would be helpful. Of course, other forms of treatment would still be needed.

I was thinking about this today. Neuroprosthetics with feedback is the most exciting. The type where people can actually sense touch on the prosthetic limb...but it's probably still in the "research" phase. Any startup trying to do this may need to work with a doctor. You may also need to do surgery to access the nerves...or maybe there's a better way..

I'd love to work on something like this too!

This is an interesting thought. The point of logging in would be to save user state, but maybe users can opt-out of that for certain apps... hmm

I was debating including that option :P

I've just never actually seen anyone else do it.For some reason, it feels 100x more complicated than checking my SMS app for an SMS code when in reality its not that different.

Would you say that's a small percent of your user base? Most of my friends hate the idea of needing to login via Facebook, but it is truly the simplest for them - and I'm not sure if my friends are just disproportionately biased. I'm also not sure if I want to depend on a third party.
