Hi again Kev,
Many thanks again chaps.
V2 Case arrived today. Using the old end piece of the classic case as a template managed to drill a neat 7mm hole which has turned out to be spot on position wise. I have then drilled out the pre-blanked hole for the 1090 antenna too.
Good work!
However, no screws came with the case to secure the Pi.... which is annoying as i have no idea what screw size to get!
So, next steps are to get some screws, although not sure what size/type.
You shouldn’t need to screw the Pi in place. Once the Bridge is in place it should just slot in place and be held by the upper case.
Do I remove the plastic casing from the nooelec nano 2 SDR dongle? Or just leave it (assuming it doesn't get too hot).
I’m sure the Rosetta’s still have the case on the NooElec -Ash, can you confirm?
I may upgrade the Pi to a 3B or 3B+, I assume this will not affect the position of the Aware Bridge and antenna?
Definitely worth upgrading to a Pi3 as it will be much faster, removes the need for an external WiFi dongle (it’s onboard on the Pi3s) and adds Bluetooth audio output. Lee has recently recommended the 3B (which is standard in Rosetta) over the 3B+ as it draws less power, though I have been running a 3B+ for well over a year in one of my test units without any noticeable issues. Mind you, mine is powered by one of Jeremy Curtis’s ‘Charge 4’ aviation power supplies.
There are two fans in the case, one is USB powered, the other has a two pin connector, though not sure where to connect that on the Pi, or as above do I just do away with the fans... I guess they use power and if serving no purpose is a waste of battery.
The 2 pin connector normally fits onto two of the pins on the 40 pin GPIO connector, but in our setup all the pins are taken up by the Bridge. I could check the PIN numbers for you, but as you’d need to solder the leads to the top of the pins on the Bridge (definitely not recommended). If you did get any heating problems you could plug the USB fan into a spare USB port, but this is very unlikely to be necessary.
Best Regards
Peter
p.s. If you do change the board, you will need to contact Ash (
support@pilotaware.com) and ask him to transfer your licence as it is tied to the 12 digit MAC address of the Raspberry Pi. He will need your name, email and the old & new MACs.
