A friend of mine and I were having a few after a sail today , and he starts going on about Raspberry pie . I asked , pie and beer ? ? And he says no Raspberry Pi the mini computer , you can buy one and a few other gadgets and make a GPS and a send and receive AIS for the boat for under a hundred bucks . Then he started showing me stuff on his phone , so apparently it's possible . Have any of you done this ? Thanks for any reply , Ms.westi and I will be heading out for a week or so and she won't let me look at her new smart phone (I wouldn't know how to work it anyway) so I will talk to you all later . Have a wonderful 4th !
