During the last dev call we spent a bit of time discussing the OpenCTD project and the group had quite a few questions about it. It fits right into all the discussions we're having on the forums about sensors.
We've set up a G+ Hangout with them to talk about it further. We're going to be chatting with Kersey Sturdivant of the OpenCTD project next Tuesday at 12pm PST. It will be a good chance to pick his brain on the sensors they're using and learn more about their plans.
Kersey is a Post Doc at Duke University Marine Lab, so we can also ask him about what scientists are looking for (and excited about) in terms of open source hardware.
