in the case of using a cut PWM cable. Crimp Red female spade plugs to the raw end of the black and white wires. Female spade plugs look kind of like a B from the end, and should have plastic all around. Red means it is for small wires.

Always do a pull test after a crimp. If you can yank off the connector then it would have fallen off during a match!

Can you take photos of your electronics so far? if you can attach them here, we can give it a once-over.

UPDATE: the microswitch was are operational, the robot is wireless, the Driver Station reads voltage.

NEEDED: what are some methods of reading when the micro switches are active because I can only think of the driver station lass in Java. Or does it show up on the driver station. I saw the PSOC I/O device and I had it installed before re-imaging the Classmate, so does that mean that I have to do that again?

When I try to run a default camera program, I get an error in a Windriver code not existing (this is java not c++. Silly netbeans) but seriously, it is confusing to find out how to make the Axis 206 camera working. If I can get an image to feed to the driver station, then I can attempt to build code to detect the environment with tutorials and chiefdelphi!

I have downloaded and installed the Kinect SDK and FRC Knect Server. I plan to test it tomorrow but how does it respond? I could only set it up today. We tested the Kinect via the SDK and it is operatnal!

TIPS: I have learned that when. Jaguar is moving a motor (for sample:CIM Motor), that when a conveyor belt system has enough friction, the following can occur:

With too much friction and the wire sparks and heats up, direct battery Test on CIM motor.

When there is some friction, the Jaguar has to accelerate. If it goes from 0 to 1.0 in speed with force, it overheats for 3-4 seconds and resets. So you have to accelerate or inch closer until the speed is just enough to have full power from that point.

**As for photos, I will see if I can get some tomorrow. We got our cannon initially mounted, so the electronics board looks like a scary cave with an orange RSL and blue and green power LEDs.

Thank you all agin in advanced and this crunch time robot is workin faster, how strange? Well Happy Competitns and have a merry crunch session!

By the way, I cut a PWM and put the wires through the microswitch hole, wrapped it up, and covered it in electrical tape. Lt me see if w have those connectors.

P.S. I only did that due to a lack in connector-use knowledge.

Thanks again!

Solder those wires if you can't find quick-connect connectors. Just twisting them on WILL FAIL during competition.
Or get help when you get to competition, ANY veteran team will have them and help you put them on.

At the South Florida Regional, ask Team 174 (Children of the Swamp, from Riviera Beach) if they would be willing to lend you an experienced student for a while. Tell them Chief Delphi sent you. :)

Thank you in advanced, this is getting clearer but not there yet.

Yes, you should be cutting off the male end so that the female end is retained. On the end of that cable, fold back the power wire then heat shrink around it to ensure that it is impossible for that wire to make contact with anything. If heat shrink is not available, electrical tape or anything that will isolate the wire is an acceptable substitute. Following that, strip the ground and signal wires back, then solder them to the appropriate tabs. Insulation here is optional, but highly recommended if the environment poses a risk for shorting. Alan explained the wiring configuration in his post.
