@ Geoff Re the Silicon Chip Boat Computer. A great article Geoff. I had a similar project almost finished but this is so much better. My only problem is that I want to use it to find my fishing spots and 4 POIs is not enough. I would ideally like to have 10. Is it possible to make POI4 read "More" and go to another screen with 7 more POIs. I have looked at the code but I find it difficult to alter code that I have not written myself. Thanks Paul.

The fishing must be pretty good up there Paul - I was thinking the same thing for some places down in Tassie I visit occasionally but then I thought Geoff would be justified in asking for a few coordinates for his next trip  Gotta keep these things to yourself! |

I'm more of a golfer than an angler but the fishing up here on the Great Barrier Reef is certainly the best I have ever encountered. Like you say you have to find your own marks they are a closely guarded secret, some of the guys up here would have thirty or more. I have an idea for a device combining a compass and GPS so that when out fishing it would be possible to get a fix on another boat from a couple of different locations and find out his position.

That would be extremely useful for Sea Rescue situations, care to expand on the idea ? Cheers Chris http://caroper.blogspot.com/ |

It would only be for situations where the other vessel could be seen. My idea is to get a compass bearing on the other vessel and note the coordinates of your position. If you then move to another location 1 or 2 Km away and do the same thing you should be able to calculate the coordinates of the other vessel. However I don't think the compass would be accurate enough 1/2 a degree over a couple of Kms would be a fair distance. When fishing we have to be within a few metres on some of the very small reefs.

I reckon it would be easier to just motor up to them (all innocent like) and ask them what the time is, or have they heard a forecast, or some other such irrelevance  . Of course you would have previously modified Geoff's boat computer and code to have a 'point of interest' button (like in his 'Tracker' project) that stores the current position. That button would then be pressed - mission accomplished

We are digressing from the original reason for this post but Geoff's Boat Computer has the ability to log your current location but it is a bit of an unwritten rule that you don't moor beside another boat and steal his mark.

But is it OK to steal his mark anyway without motoring alongside - like getting a fix via a GPS coordinate and a couple of intersecting bearings? |

Yes, the more that I think about it this should have been in the first version. I will add 7 or more POIs and post the code here. Just give me a couple of weeks (I have a lot on at this time). Geoff Geoff Graham - http://geoffg.net |

Thanks very much Geoff, the other boaties I have shown it to are very impressed. Paul. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

Another vote for more POI capacity, although I'm envisaging their use as Waypoints. I'm thinking of slightly modifying some of the code to better suit its use in an ultralight aircraft, where it will be equally useful to measure ground speed and heading as it is Geoff's Boat application. It wouldn't have all the navigation functionality now available on moving map gps or most of the latter tablet offerings but it is cheap enough to have permanently installed in the plane. Bill Bill |

Humm... I like it when you use words like "Ultralight Aircraft"  |

| Bill7300 Senior Member Joined: 05/08/2014 Location: AustraliaPosts: 159 |
Well, not quite ultralight aircraft as you probably know that term in the US, Zonker. We in Oz we have that category available for two-seaters, or single seaters for that matter, up to maximum take-off weights of 600 kgs, which if my 68 year old brain has retained the correct conversion factor, would be 1320 pounds. I fly both my Jodel D18 and the X-Air Standard as ultralights and will be registering the Murphy Rebel and Cygnet SF-2A as such too, once finished. Bill VK7MX Bill |

Wow Bill... That is a bit over the limit here as you said... For awhile, there were many 2 seat "fatralights" like mine "300lbs" or so... But then the FAA came up with the "Light Sport Ticket" which made a new class, so they are very hard on keeping the limits nowadays... 254lbs or less (dry)... It's been awhile since I have flown, but want to create some Micromite instruments for the fliers back here... Keep on flying Bro..! Awesome..! |

LSA also exists here, within the ultralight category too. With you on creating Micromite instruments for ultralights. One of the other attractions of the category is freedom from certificated instruments, much like the Experimental category there. Allows me to align my aviation, electronics and amateur radio interests. Bill |
