My board, while mounted to an RC car that wasn't supposed to be switched on , took a dive off my desk while attached to the USB cable. The cable was tugged out during the fall and the port had been sketchy ever since. The cable had to be held in a specific position to make the connection. The moral of the story, use a stand for RC car projects. Dustin Note: This morning I finally worked up the nerve to try resoldering the tiny connectors to the board and now my board is as good as new. Woohoo! EDIT: Feel free to move this to the proper place. It probably belongs in General Discussion. Sorry about that.

I too am doing an RC car project. A while ago, I was testing my ESC driver, when I forgot to turn the motor off. The motor promptly spun up to full RPM, and in doing so, rocked back in it's stand. When it did so, the wheel caught a wrench sitting on my desk and threw it right through the dry wall behind the setup. What RC car are you using? I'm using a hopped up Traxxas Stampede.

I've actually read some of your blog posts about RAWR. Particularly the stuff about the IMU. Amazing that it has the power to shoot a wrench through the drywall.

I'm using a rather old Radio Shack Monster Patrol for mine. Nothing fancy about it but it has decent speed and torque to it and has been interesting to reverse engineer. It's turned out to be rather easy to get moving due to the RX6 ATS306R receiver chip that is uses. If this one turns out well, I'll probably invest in a better base car to use.

If you are interested in the IMU, please shoot me a PM. I wasn't too surprised when the wrench went through the drywall. It made a loud BANG that made me jump about a foot off my chair, but remember that the motor has to accelerate a large, heavy chassis up to ~30MPH pretty rapidly. That takes a pretty good amount of power, so accelerating a small, sharp hunk of metal shouldn't be any issue. Essentially, what I had was an overpowered pitching machine. ...It's a good thing it was in FORWARD not REVERSE. That would be an interesting ER visit
