yes thank you for fixing the link. some how some extra characters got
added in to the link.
i will be showing this at a talent show on may 10th. i just finished it
yesterday. it was such a nice day outside and i don't really have a flat
surface long enough to set it up in my house, so i set it up outside. i
made this bridge from pictures of the real bridge and a little inspiration
from TJ Avery. the hawthorne bridge is about a mile away from my office so
i spent a lot of time just looking at it.
you are right about synchronizing the motors. one of the motors runs
faster than the other. i made the string a little longer on one side. so
when the bridge starts to go up it is a little lopsided, but by the time it
reaches the top it evens out. not a very good solution but it works.
