Unmanned ocean crossing

This is the Pinta, an autonomous sailboat built to attempt an ocean crossing from Ireland to Martinique (in the Caribbean). A group of researchers at Aberystwyth University built her as part of the Microtransat Challenge.

[Doug Paradis] took a good look inside the Air Wick Freshmatic Compact i-Motion and then stole all the parts for other projects. We’ve looked at adding a manual spray button or making air fresheners Internet enabled before.

Curious about what takes up that much space, we were impressed to see all the features demonstrated in the video after the break. The small device, running on two AA batteries, has a … Read the rest
