That is way cool,,,hows the project coming along, I have a similar thing in mind,,,a wee while ago I built a US1metre "thats a model sail boat" It floats in the same way a brick doesnt.
but Ive still got the sail winch servo, and the remote unit,unlike a normal servo this one does about 8 revolutions either way. would love to set that up on my piggy scope. did you get anywhere with the PC serial connection.? and the curcuit for driving the servo, can you be more specific...on the design and function. Im extremely interested..
Cheers Shawn
