sunday of servos and sizing

-karlin, caroline, divya, sallie, and i spent lots of time trying to get the servo set up. in true labview fashion, the actual coding consists of dragging blocks that say "servo open" "get angle" etc together. and yet, it Would Not Work. and we were very frustrated, tried to figure if we needed a speed controller [which would make no sense], messed around with the oscilloscope... and of course, the problem was something so stupid. you need a jumper on the pins next to the PWM. thank you, some random guy on a chief delphi post. as soon as we plugged in the jumper, it worked perfectly. GAH.
-much time was spent discussing where to put gearboxes/motors and which orientation they will go. if we do them the "traditional" way/the way we've done it in the past, there won't be enough room in the middle for the corkscrew. i think the final decision was to place them on the outer bars of the chassis, though i am not sure. i'll double check tomorrow. anyway, the finalfinalfinal chassis drawings were made, and sent to ideo with jimmy. meaning - we're on our way to having a chassis!
-made an order list of sprockets, chain, masterlinks, encoder stuff, etc. this doesn't sound like it takes a lot of time, but uh, it does.
-sallie and divya started to build a potential gate for the servo to turn. the thing's going to have to be really light because the dear servo is incredibly wimpy. although it turns 90 degrees quite beautifully.
-annie and allie were solidworksing. sorry i don't have more details. :/

thank you to the huang family for food and chaperoning and to karlin, doug, and jimmy for their infinite wisdom. and divya often says "you guys deserve a gift."
see you 5:15-8 this week?
