Summer Accomplishments & Presentations

First, we're at Seattle Mini MakerFaire ( this weekend, in Maker Alley! If you're there, please come by and say hi!

Second, I gave two talks this summer -- a ten minute one at MakerFaire Bay Area and a longer one at Toorcamp. I'm still working on getting video of both -- in the meantime, here are my slides:

On the hardware front, we've gotten the wing molds fabricated and will shortly begin pulling some test parts. We've also put together a full set of cut files for the hull of the Microtransat boat.

We also added compasses to the wing sails in order to allow us to estimate the wind direction without additional hardware. This simplifies the boat and removes one more system (wind vanes) from the critical path.

Most of this summer's progress has been in the software realm -- we've spec'd out and written most of the necessary modules for the Microtransat boat. We're adding them in to the little boat's control system one at a time to test how they work in practice, and sailing them in Lake Washington when our schedules and good wind line up. Since the boat is a bit on the heavy side, it's not a particularly good sailor and really needs about 10 knots of wind before it performs decently. That's good enough for software testing, however.

We're looking forward to additional sail testing this afternoon, and we're also exploring resurrecting TSV Disputed Right of Way for creating a database of tagged images of the marine environment around Puget Sound.
