RE: A beginner can manage it! - RPi3 + Sensehat - Leigh - 2017-12-08 All working now, I also got a DTL AIS dongle and am currently organising DIY antenna. I am very happy with my scanned and calibrated paper charts I have messed about with the location of the sensehat to avoid the self heating of the temp sensor; I used it with the ribbon cable and sensehat outside the shortcrust case which gave good values but isnt that practical Then I got longer GPIO pin blocks and stand-offs and used the case extensions of the shortcrust case to put the sensehat further above the RPi in the case with 1cm thick of expanded cardboard (i.e. 2 layers from a thick box) insulation but this still gave elevated temps. Next step is to use 1 cm of real foam insulation, but I am not sure if self heating comes from RPi or from the sensehat itself. Actually, I think I will just buy a little thermometer, forget the air temp and just have the sensehat in the unextended shortcrust case - what do I want to know the air temp for? Thanks for all help Update: With 1 cm thick polystyrene insulation cut to seal completely around long headers still giving too high temperatures. I'm going to forget about temperature RE: A beginner can manage it! - RPi3 + Sensehat - Leigh - 2018-01-11 My New Case Will the compass in the Sense Hat be affected by the USB Hub so close?

There are 2 versions in the app store, the free one is old and not supported, the paid version is the real one, doesn't cost much. I just noticed / realised the significance of this part of your reply above How do I use openCPN on the tablet (which is much quicker, you are dead right) but still access the AIS etc data from the Openplotter RPi on the tablet?
