Bon Voyage, Snoopy!
By Dermot Tynan, over 11 years ago.
Today, March 23rd, 2013, Team Joker are planning to launch their ninth boat, Snoopy Sloop. This has been an educational (and obviously fun!) experience for Robin Lovelock and his fleet of robotic warrior boats. Here in Beoga Beag land, we wish them well.
Wind Direction Indicator
By Dermot Tynan, over 11 years ago.
Now that the hull is looking solid, it's time to start thinking again about the wind direction indicator. It is possible to detect wind speed by using an ultrasonic sensor and receiver, and measuring the delay between the two. You need to account for temperature changes and gusts can cause issues, but it is fairly reliable and has no moving parts. Generally, you use two transducers offset by a distance of perhaps 20cm for the North/South computation, and another pair in the East/West direction. I think if we were using a larger hull, such as a 4m boat, this would be a good plan. But, for the 2.4m (or the 1.2m) boat, it's just too big and awkward. Also, this jury is undecided about how well they would work, over the long haul.
