Is there an available rpi module that can make phone calls on the 4g network?
I've seen many that can use 4g internet but haven't found any that can send and recieve sms or phone calls?
That won't be able to do enough image analysis at fast enough rates. Plus I need IO to drive solenoids.Imperf3kt wrote:To be perfectly honest, I think a simpler solution might just be to invest in one of those wireless CCTV systems. I know they can do multiple cameras, but I don't know about 24!.
Can't I just have a big wire to minimise resistance?Imperf3kt wrote:You can do it like that, sure, but I imagine you'd need multiple buck converters. DC doesn't travel very far. 12M even, will be too far.
