The Pi3 arrived yesterday. It was even faster to set up than the Pi4, but I attribute that to a faster WiFi connection rather than anything else. In any case, it's up and running with Apache web server and PHP on it.
As it will be used remotely, I bought a portable phone charger to power it. This one, in fact. Right now, I've got my Pi4 running a ping command every 2 seconds to see how long the Pi3 will run on the battery. The system looks like this.
|Thanks to wife kitteh, it's a very festive Pi3.|
I don't have time to test the camera connection right now. That will have to wait until tonight. Last weekend, I tried hooking the camera up to my Ubuntu server and taking a picture through that, but while the camera identified itself over the USB port, it refused to admit that it was, in fact, a video capture device. Like a pouting girlfriend, it wouldn't respond to the server and so I gave up until the Pi3 arrived. Maybe it will have more luck. If not, there are commands to make the Pi3 recognize it as a video device via the camera's unique ID.
This is fun!
