Re: Raspberry Pi 3 B+ lockups

James, I think you do have one of his SD cards in a Pi3B+ he sent you (he wasn't saying it was the SD card) It's obviously the 3B+ Ethernet chipsets having problems (soft or hard), but it may also be the way it interacts with some methods from the routers ethernet chipset, which can be found here (V...

I've just had a look through your posts and cannot see a mention of the router etc you are using, or if you are running through other switches/powerlines or a direct connection. Is the router at default setting, does it have some other option been enabled. Somebody else may be able to recreate your ...

I've already got a decent iron I bought at Maplin many years ago, but a spare might be handy. I didn't see any when I was in the nearest local Aldi yesterday, maybe I need to try one of the other local ones (we've got at least three within 7 miles of me).

Link to the Aldi one

Quite a bit cheaper than the £45 one TS100 on ebay uk.
Though I'm used to push on ends.
I use Antex CS18 and XS25 myself, I find rosin free more of a pain than lead-free.

Re: Why do some people prefer a cluster of RPis over AWS?

How does MythicBeasts run its Pi's?
Clustered or just individual access?
They were used for the PiWheels iirc and as an Apt Pi mirror.

Either way you can rent a Pi in the Cloud.

I would find a corresponding whetstone amplifier that then converts it to digital output. Probably over i2c.

Basically, stick it in and find out ;-)

If it doesn't work, it's probably easier in the long run to get one that does.

But being a Microsoft one, it will more than likely work fine.

Re: RPI_GPS_ADD-ON_V2.0

Not sure why you need to turn Bluetooth off. It should work (ublox6) off the noraml /dev/serial0 line once you have Enabled the Serial Port and Disabled the Serial Console. The only reason would be to take the full UART, but I've never needed to. (that's with 3B and ZW's though, 3B+ should be the sa...

Why reboot, why not just schedule (Cron) a lookup to see if there is anything to update.
Only then rabbit if it needs a reboot?

I'm sure most python programs can be stopped, updated and then run without any need to reboot.
