It's awesome to see FIRST teams trying to spread their own knowledge that they've accumulated over the years in things like this. There's one problem, once every team has a wiki, you only have google to find what you need, and even that's not great at finding some of the more obscure FRC wikis. To solve this, we have the
FIRST Wiki. Most of these pages would work fantastically as just a copy and paste job to them. You can put a link to your own wiki in the bottom of the page. If you don't care to add them there, I'd be happy to take the time to do it either. All you need is a github account. You can also add you team's page there as well.
Some stuff you shouldn't move over and makes more sense for your own wiki, like the summaries of robots and robot mechanisms, but the "lessons learned" can be include in the respective page for it.
Also, that pixy mount looks amazing. We have at least a half dozen of those sitting around, and that looks like an amazing use for them.
