I had this bright idea of using the screen from an old laptop, but after reading a thread where it took a bunch of techos years to sort out how to do it (and then it looked like a dogs breakfast) I gave up on that idea.

So, any pointers to a budget small 12v LCD to run a VGA output would be most appreciated.
I suspect you may have problems here. We have never found a marine proof screen that would stand upto yacht (or rib) cockpit conditions at anything close to the price of a normal screen. We use a laptop connected to a regular tft screen at the inside nav station running our nav/racing software. We did look at wlan terminals (rdp) but i think they were 3500 for the B&G unit, at which point we gave up on the idea.

We now use the pc system for passage planning and tactics but on deck we use a garmin 60csx for supplementary close work. It also serves as the backup nav system before having to revert to paper!

Thanks Richard and JW for the comments.

I've been on holiday, and couldn't get on line. What I thought was wild weather interfering with the phone lines actually was zone alarm blocking the dialup. Oh well, good to read for a change.

If for the cost of a waterproof screen you can buy a chart plotter, that defeats the purpose of the exercise! It seems suprising that with the low cost of LCD screens now, that a small remote unit isn't readily available. The in car 12v LCD screens are the cheapest option, but waterproofing and sunlight viewing might be a problem.

Richards solution might be best, the cost of the screen goes a fair way towards a mapping handheld GPS.

Cheers

Except, if you're over 50 and can now only read big letters and feck all close up without reading specs.


If you're younger and feeling smug, your turn will come too.

Ah but at current rates of development and price drop you will be able to get a fully waterproof chart plotter with an enormous screen for 100 - negating the problem!

Of course by then fuel will cost 10/L too so noone will be able to afford to navigate anywhere!!!

The sooner the better then!

Talking of which...the preferred option of keeping red diesel available sounds good but the duty will be more than road diesel cos it's a high sulphur fuel. We can't win.

There is one realistic option that's occurred to me. Thats the Nokia 770 tablet. Its an 800x480 screen so better than vga. It has built in wifi. if you use vnc (remote screen control) it can operate as a handheld screen. Issues to consider:
- its not waterproof (aquapaq?) but very slim and pocketable.
- finding a screendriver for your laptop for native 800x480 may be a challenge. Could run pc ok at 800x600 - this would show with a scrollbar on the nokia.
- screen is small if you are 'over 50' (to quote others) but v high quality.
- dirt cheap now (you can find them for 85 new) and really do work (Im using one now and do use vnc on it too)

I cant believe i hadnt thought about this before!

I think a 770 might fit in one of the Otterbox cases designed so you can use the touchscreen through it... IMHO much better than an aquapaq.

Richard, that's a damned interesting idea

Someone needs to try it.

Ironically, the 810 (the new model) comes with GPs. If the navigation fails, on the 810 you can also watch you tube RIB and rescue clips while you wait. This is called technological convergence.

Well I have tried vnc and can assure you it works fine with both pc and mac (anyone mention a Newton!!!). I haven't tried with a navigation s/w package and on deck. However, no reason to suspect it wont work as its simply a remote presentation of whats on the pc screen. Just a question about readability etc.

I may have a go only the boat but it will prob take a few weeks before I get the time to set it up.

vnc works fine with the mouse/pointer. If you need to enter text, you need to use the windows on-screen keyboard utility. This is ok but not quite as handy as the Nokias own one.

Interesting point about inbuilt gps once the latest version. Ive read that the 800 is now being discounted too. Nokia, seem to be continuing to develop these devices. Once ubiquitous wifi is available they will really come into their own.
