I count 12 motor controllers, but there are only 10 PWMs in the digital sidecar. Are you running two controllers from the same PWM?

I love the neatness. How do you keep it neat when you use light sensors and solenoids?

Two PWM signals each go to two speed controllers. You can see the Y-splices where the cables round the corner to the Talons with fans. Those are obviously intended for the drive motors.

The motor wiring, control system component power, and heavy battery connections are also missing. I'd enjoy seeing how they were kept from detracting from the neatness. Would you mind if I came over and took a look at Championship? (Congratulations on another San Diego Regional Chairman's Award, by the way.)

I'll try to get a photo from our competition robot this weekend. The solenoids are tricked to get right.

Please, feel free to take a look. Things do get more crowded, but overall, the board is still neat.

What 1/16" rubber adhesive backed rubber sheet do you use? We bought a roll of Bump-On from McMaster-Carr this season, and the stuff costs a fortune.

The rubber isn't 1/16" thick. It's a 1/32" thick sheet of adhesive backed silicone rubber. The McMaster part number is 8622K41. Apply the adhesive side to the bottom of the cRIO chassis so that it travels with the cRIO. We covered the bottom of both of our 4-slot cRIOs and still had a lot left over.

Any chance you could post a pic of the finished board?

I'll probably be by at Championship to check it out anyway, but I'd like to show it to my team as an example of proper wiring. (Our electronics boards tend to end up looking like a bowl of multi-colored spaghetti)

What type of aluminum are you using for your board? Is there a specific reason for that shape of lightening patern?

This makes me cry a little inside, because compared to our electronics board, this is perfection...

My guess is 6061. There isn't much reason to do it in anything else. The lightening pattern is something a lot of west coast teams use. It makes it really easy to route wires.

The belly pan/lightening pattern is actually inspired by 233 who used it long before 2009 when 254 and 968 started doing the same thing.
