i have come to a robotics forum for help as i do not know how i will control the flexinol, i know you need to pass a current through it of say 0.4A but then it could easily overheat, so was considering having it pulse so 0.5sec on 1sec off etc... so it wont overheat and it will stay curled up, maybe move a bit but it would look cool.
i had an idea of using a servo controller? 1 petal per output on the controller, something like the ssc-32, im not sure, there might be a really simple way of doing this that i am completely oblivious to....
ok, after doing research for the day as i have been given no information, [...]
the first is i have thought of a way to control the 12 pieces of flexinol using a 12 way switch and a mechanical clock (obvious really).
the second being is i read that you can run current though a 0.006" or less diameter wire constantly without fear of overheating, if this is the case then it will be a massive help. can anyone confirm this?
The wire i want to use is the 0.006"LT http://www.dynalloy.com/TechDataWire.php and roughly 3inches long so 4.8ohms/inch and 410mA for a 1 second contraction.
