Fried relay controllers on the Digital Sidecar

[Jon Stratis]

We lost a DSC this season (we think) due to swarf... things stopped working on it in a match up in Duluth, and when we got back to the pit, the 5V LED wasn't lit anymore. We may have been able to resurrect it by blowing it out... but rather than take the risk of not getting everything, or having it fail again, or spending a long time blowing it out with no results, we went in and replaced it with a backup. Testing to see if we can get it working again is still on our "todo" list!

The big flashy light is driven off of the same chain of shift registers that the relays are. It makes sense that both of them could fail at the same time.
