cheaper large instrument displays - mast mount

I've got several Wellers - I've had them for about 25 years. I'm not convinced anything else would survive 25 years continuous use! Mind you, they are beginning to fail now - I'm beginning to run out of bits to canibalise to keep them going.

I see that Rapid have some variable temperature stations for about £40 - I expect I'll buy one of those sometime.

As for de-soldering - there's (IMHO) only one way to do it - vacuum. The spring-plunger desolderers are too violent for modern fine-pitch PCBs. Unfortunately, wick isn't too good at removing solder from plated-through holes, so the only sensible way to do it is vaccuum - and vacuum de-solderers are relatively expensive. I use a Pace hot-air/vacuum station, but that cost about £500, so not something I'd suggest to a hobbyist! Again, I think Rapid offer a lower-cost alternative.
 
Don't bother with a hot-air station, unless you plan working with surface-mount parts. You won't use it for anything else - it's not man enough for paint stripping, etc!
 
Your not wrong...although I have just spent the last hour watching you tube on soldering SM devices...it is over 20 years since I last did any serious electronics and it was nearly all through hole then..

That's not to say that now is as good a time as any to get started...I am keen to learn new skills and am thinking of buying some bits to overheat and break for practice...I am a perfectionist by nature so this should be right up my street...when we go further down this road I may be able to be more helpful with a bit of practise now

It seems I am very behind the curve at this level...I am hoping I can become more useful as time goes on...
 
I offered to help write up the instructions and manuals. Can I take that the presentation data is now pretty well confirmed as in Angus' post#295 here:


"BOAT SPEED KNOTS"
"DEPTH METRES"
"DEPTH FATHOMS"
"DEPTH FEET"
"COURSE OVER GROUND"
"SPEED OVER GROUND KNOTS"
"CROSS TRACK ERROR"
"WINDSPEED TRUE m/s"
"WIND ANGLE TRUE"
"TRIP DISTANCE NM"
"WINDSPEED TRUE KNOTS"
"HEADING"
"WIND DIRECTION MAGNETIC"
"VELOCITY MADE GOOD"
"WIND ANGLE APPARENT"
"WINSDPEED APPARENT KNOTS"
"WINDSPEED APPARENT m/s"
"WIND DIRECTION TRUE"
"TOTAL DISTANCE NM"
"BEARING TO MARK TRUE"
"SET TRUE"
"DRIFT"
"DISTANCE TO MARK NM"
"BEARING TO MARK MAGNETIC"
"SET MAGNETIC"


or are other outputs envisaged please ? Anyone got e.g. a Brookes and Gatehouse or Raymarine manual with a list of outputs ?
 
Thank you for writing the manual...a much needed and usually underrated skill that is sooo very difficult

err, "I offered to help write up"


So that's me lumbered, yes ? :)



EDIT

that Sailclever manual is v useful. Ta.
 
@sarabande:
I have the manual for the B&G FFD's, it states which NMEA-sentences the NMEA-FFD's put out (page 11). See attachment.

@all:
I really follow this thread with great interest, thanks all for the great input.
One think we might consider: I think it would be a good idea to provide the display with some sort of cover to protect it from the sun/uv when not in use. What do you think?

A molded plastic one might be really expensive to get tooling to make, but an elasticated fabric one could be sewn for less than a £ and would do the job just as well in protecting the LCD.
 
hmm..pot is connected but does not seem to alter it very much..i have ploughed on anyway and now have everything connected.

Having a bit of trouble compiling the code..i get the following:

[cc] c:/gnu_tools_arm_embedded/bin/../lib/gcc/arm-none-eabi/4.6.2/../../../../arm-none-eabi/bin/ld.exe: mast_display.elf section `.co_stack' will not fit in region `ram'

[cc] c:/gnu_tools_arm_embedded/bin/../lib/gcc/arm-none-eabi/4.6.2/../../../../arm-none-eabi/bin/ld.exe: region `ram' overflowed by 144 bytes
[cc] collect2: ld returned 1 exit status

Any ideas?
