Biggest issues are cost and size. I'm currently at "1977 Apple" stage - a big, expensive, hand-made prototype. But the biggest issue is cost per pin. Also, resolution is an issue... I'm going for "big and expensive" first, then will work on making it small and cheap overtime. I'm working with small dc motors first, but there are plenty of electromechanical tricks to get this down to braille-worthy stuff.
- gsivil 16y agoThis seems like a project that the MIT media lab would like to put its hands on. Why do not you seek a collaboration.
- hugs 16y agoI'd love to chat with the MIT media lab folks. If you're so inclinded, check out my HN bio and have them contact me via email or twitter. ;-) I haven't sought a collaboration yet, because "pinmachine" is my weekend project -- my time is otherwise filled up working on my startup (saucelabs.com).
- wazoox 16y agoI had a thought about it, ideally it would be a pin board (like these http://www.youtube.com/watch?v=ikkjT7ACJME http://www.youtube.com/watch?v=ikkjT7ACJME ) with solenoids or similar motors on each pin... somewhat similar to core memory too, with a different geometry.
- hugs 16y agoYup, that's exactly what I'm going for... It'll be really cool when you can program anything to appear. My dream is to make it large enough to render "Han Solo in Carbonite" on this kind of display. :-)
- wazoox 16y agoI suppose that "big enough to palpate with both hands" would be already a tremendous progress for blind people :)
