That's not the trick. The reason for having two of the jumpers was simply that the four wide jumpers were all but impossible to come by this year, and we had a source for the three wide jumpers. Apparently, the documentation for the jumpers says that stacking two jumpers (a three and a two) on top of each other like this is an acceptible way to make a longer jumper.

The trick Pavan's talking about is the rigamarole we went through with the PDB to keep it from becoming loose at nationals. We went through a process of:

1. Removing the crappy slotted screws from the PDB.
2. Turning down nice caphead allen screws on the lathe so that they'd fit in the plastic housing.
3. Crimping and soldering on the end of each power wire an Anderson Power Pole pin.
4. Sanding and bending the pin slightly to become a hook that will fit flat into the PDB.
5. Tightening down the nice new capheads on top of the modified APP pins.
6. Locktite the screws from the side of each PDB section.
7. Tape the part of the APP connector that sticks out from the PDB

This process took an entire fixit window to complete, and although it was tedious and slow, we had not a single problem at the championship, after constantly fixing it at both of our regionals.

Re: pic: 2007 Robot Brain

Wow, that is much better than our electronics. Our mechanical components were all modular, but since the design changed a lot during build season, our electrical components were mounted rather haphazardly, and our wiring looked like a bundle of spit, with some desperate attempts at order. This is definately something to consider for next year.

Re: pic: 2007 Robot Brain

I was finally able to obtain the CAD files of our brain box. If you would like more pictures, drawings, or anything else pertaining these files, I will try my best to get them to you. This is before we designed the cat plate and so there are no holes. I think this is wate Arefin and a few others wanted posted.

Enjoy!
