I even cut out some steel flashing and screwed it to the runners to (hopefully) make it slide a bit better
In other news, I went to MITERS this evening for the Balancing Things Colloquium! Charles talked about Segfault and LandBearShark, Jordan showed off her (somewhat) balancing skateboard, and Shane demoed his extremely low budget segway. The drivetrain is nothing more than a couple of cordless drills zip-tied to a piece of wood. The wheels even go in their chucks! 4PCB was also present as a controls example. There was lots of talk about PID loops and tuning, which was awesome!
But wait, there's snow much more to talk about:
The epoxy was unlike any epoxy I've worked with before. I mixed a small batch, and it was very runny. I waited a few minutes for it to cure, checking on it every minute while I listened to the balancing-things talk. It was heating up normally, but still runny, then all of a sudden, the whole thing turned to gel -- Like very hard, chewy, sticky Jello from hell.
After being totally taken by surprise, I mixed up another batch and applied it to the board, still runny. That's why the board is over a trash can. I didn't want it to drip on any nice things.
And it looks like the epoxy will have just enough time to cure before the snow starts.. sweet!
