Re: Fried relay controllers on the Digital Sidecar

But with 40 minutes to go, we realized that was it. (The compressor was the only thing on a relay port, but since both climbing and shooting required air, it wasn't exactly optional.)

We had to disassemble part of our new blocker to be able to unfold the robot and reach the DSC, and then the wire moving began. They finished moving all the wiring, confirming the compressor now worked, and checking the shooter and wheels for function, and got everything buttoned back up just as we needed to cart up and go. Then we realized the signal light wasn't, so that got fixed hastily. They picked up the robot, and as I was about to run the cart under it, another mentor noticed a dangling wire, we froze, he tied it back in, we put the cart under, and the drive team headed for queuing only two minutes behind schedule.

Once they'd left, we took the DSC and tapped it upside down on our podium and took a sad look at the pile of shavings that came out, probably having arrived during one of our emergency mechanical repairs in Arkansas. I don't quite know what we're going to do to protect it next year, but we're doing something.
We've had our electronics mounted vertically for the past 2 years, and the only sidecar we've blown was wiring the power backwards during build season in 2012.[/list]
