The construction of the large shed started on Monday. Here is a couple of pictures taken from my office window. They were supposed to pour the concrete today, but it was delayed to Monday. Between the utility room and the large shed, we have an underground Carlon pipe. Our Starlink cable and a Cat6e will be run through it. I plan to have the Starlink antenna attached to the fascia of the shed. I also want to add an Arduino with Ethernet shield along with some cameras (hence the Cat6e). The Arduino will monitor a sensor that when triggered, it will send a UDP packet to my server, which will then take a picture. I want to take pictures of the cars who pass on our road. Half of the road is ours and the other is our neighbour's. I hope he will allow us to put a sensor on his property if we give him access to the pictures. I have already created a C program that receives a UDP packet on port 9797 and sends its contents as an argument to a bash script. That bash script will then use curl to take the picture and put it on a website. (I use xinetd to start the program, which then uses read() on stdin). I use UDP because I don't mind missing a picture. The contents will be either "LO" or "HI". Normally HI, LO when triggered. (I plan to use the internal pull-up resistor and connect the normally open contact of the sensor between ground and the pin).
