Encoder Operational

So, after I plugged things in the wrong way a couple of times, the encoder works! We scaled it so that it measures degrees. The encoder thinks that 250 is one full revolution, but we wanted it to think that 360 was one revolution, so we told it to scale by 1.44. Karlin explained code writing for the encoder and how we could use it to turn the ball-dumping motor. There is some nice "pseudo-code" on the whiteboard in the programming room. We will plan on meeting in the near future. (ideas for times anybody?)

Jimmy is working on a mount for the encoder. He made the ball stopper larger so that the ball doesn't get stuck on the metal thing (like what happened on ship). I am going to drop off a globe motor to see if the shaft on the back can be extended to make a mount for the encoder.

Also, Nan, Anne, Anna, and Shifrah worked on building a beautiful new cart today. We bought some casters at ACE to mount on an 80-20 a and wood frame.

Just a reminder, If you have any outstanding reimbursements, please e-mail them to Ms. Mourad asap so that you can be reimbursed. Also, remember to turn in your permission slips to Ms. Mourad by tomorrow. These need to be signed by you and a parent. Next week is the Silicon Vally Regional, March 12-14. All team members are expected to attend a MANDATORY TUESDAY meeting next week to discuss the competition, preparation, and what to expect. All team members (unless you have already talked to me) should plan on being at the competition Fridayand Saturday. You will need to fill out an absence form for the classes you will be missing on Friday. Please feel free to invite people to come watch us at SVR. We would love to show more people our team and how fun FIRST is.
