Turnaround

                      After it seemed very bleak that we would have a finished final product , we suddenly have a fresh wave of enthusiasm and after some thinking and some help from Mr.Srinivas , we have now a new design for each pin making it easy to miniaturize the whole thing....well not easy but easier than before, well see how it goes.

Check the picture below for the updated pin design

 

That is all for now....i am very hopeful that i will post a fully working braille cell the next time.

Problems...................... Solutions

            Well making a miniature braille cell with SMA is harder that we expected...we are trying to get it made elsewhere....other than that there is this company called Alpha Aesar which makes custom SMA components(very expensive) well see if they can give us something and then talk about reducing the prices in mass production.

One more thing I am trying to do is make my one EAP (electro active polymer) by sandwiching surgical silicone between aluminum wrap...more on that soon
