Aaron - I went to the lab this morning to begin work on the Motor Labs. I completly destroyed my Servo motor by snipping the wires on it. I couldnt tine the wires and get them to go into the breadboard, and all the soldering gun tips where rather dirty, so I decided not to solder new ends on (I am not even sure if that would work, and could create a short circuit perhaps? I will just get a new Servo next week). I did manage to get a low-volatage motor by dismantaling a tape deck i found in the component rack. It was hooked up to a really cool ear mechanism and I got grease all over my hands from it, but it was worth it. In a few minutes, and a bit of deduction as to which connector was power and which was ground I got the motor working. The it was simple enough to get it running off of a switch as well. I originally tried building my own H-Bridge out of tranistors so that I wouldnt have to order one or hunt one down. This ended up not working out so well, I couldnt make them work right. I also thought of wiring up 4 switched to the board and using that to create a manual h-bridge, but couldnt locate 4 switches either. I like the idea of using four switches though, transitors and pre-built h-bridges feel like cheaing, the four switches create a nastolgic feeling too and I think you could build a cool puzzle out of them. I eventually got a pre-made H-bridge (courtesy of Michael) and wired and programmed the pic to control it. It worked fine, and the motor I pulled out of the tape deck had a plasticf piece that would move to a diffrent spot when the motor would rotate. I wonder if this is because the motor is meant to control fast forward to rewind and if this plastic part sends some of feedback to the tape deck user.
Kazu - Could you click this link ?
Joseph - Lab6 cool.
Bennett - Carefully followed the instructions and modified the code so that it matched the example, but never got the lab to work with the H-Bridge.

Mikro - motors are fun. ISD chips make brain hurt.

Viviana - I was able to have my blinky and the servo receive information at the same time, I struggled with just the servo code without the blinky, and then just the blinky working without the servo. My only thing was getting the servo do what I wanted to. I could hear the servo receiving information and vibrating, but it would not move. I played changing the speed of the info, but nothing, I know it may have been receiving some kind of information due to the fact that I was not able to freely move the motor while it was plugged. 3/25 - I came back to work on this lab because I need to know how to use it for my final project, and guess what!! I got it to work, and I also figured out how to modify it to make it work with my final project. Needless to say, I'm very happy.
