Today a quick note on how to connect the two Pi's.

Connecting the slave to the master via ethernet

In my blog yesterday I talked about taking images in the garden. But up till now The master Pi 3 (with NoIR Camera) and slave Pi B+ (with color camera) are connected via my local network. The Pi 3 using its internal WiFi, and since the WiPi dongle was missing in my kit, the Pi B+ using a cable to my network router. This is not a workable solution, since I like to take the camera to my garden, or the field where no network is available. Therefore I connected the two Pi's using a small ethernet cable. luckily no cross-over cable is needed since the ethernet ports of the Pi are auto sensing.

 

I don't like to install a DHCP server on the Pi 3, therefore I'm using static ip numbers by adding the following to the /etc/dhcpcd.conf file:

 

# static ip address (gp 24/8/2016)
interface eth0
static ip_address=192.168.2.222/24
static routers=192.168.2.1
static domain_name_servers=192.168.2.1

 

Here is a picture of the setup:
