After that I began to do electrical (Isabel had come back!). Me, Isabel and Desirae were soldering the four encoders on (two for each robot). We used two PWM. Each PWM has three wires a red, white and black. There were four wires on a encoder and each color had a number. Red=1, Brown=2, Blue=3 and Yellow=4. Then we hooked up the encoders and PWMs by red going to red, brown to white, blue to black (1st PWM) and yellow to white (2nd PWM). We soldiered the wires (we used up all the thin solder, barley had enough to finish the job) and used heat shrink. Then after that we used zip tie anchors and zip ties to secure them onto Dulce (2nd robot we are building for the FIRST FRC Robotics Competition). Next we fixed the wiring that was on Dulce because some of the wires and PWMs were too close to the motors. We didn't finish the encoders on Daniel (1st robot we build for the competition) because part of the encoder broke and we couldn't fix it. Then the second encoder for Daniel was ripped off by someone. So now we have to buy two new encoders which cost $25 dollars not counting the shipping. And since we want the encoders now, we will probably pay extra for one day delivery since the competition is so close. Hopefully this will not happen again and people will be more careful about the wiring.

Electrical and a bit of Scrap Booking.
I went to robotics at 4:00 p.m. because I had to finish a assignment from computer class (was a Valentine Day assignment) . But I got done and that's what counts. When I did arrive to robotics I first began to scrap book a page for the scrap book. Couldn't do electrical because Isabel and Bianca were in math class. The article was still about Oscar but different image. I'm doing a random triangle design. Didn't get to finish but hopefully will finish tomorrow.
