System up and running
It's finaly working !!!
With the new controller in place the system should work for about 200 days on a 16Ah battery. I will add solar panels as well in the future but for now I'm happy the way it works.
On the photos you can see the MAX5033 with the components to transform the power from 12V to 3.3V.
On the top left is the transistor that switches the motor, there is also a diode in reverse over the motor connection to absorb any reflow of current. The trasistor BC547C can draw 100mA and since my motor only consumes around 50mA this is more then enough. When you want to use a bigger motor you might need to use another transistor or a relay.
On the bottom you can see that all components were placed to avoid bridges.
Right now the system turns on at 8.05h in the morning and runs for 11 minutes, that way the chickens get the same amount of food as before.
It was funny to see the progress with these chickens, the first time the system started up the were so scared they wouldn't come near the tube that is transporting the food. Now they would jump over each other to be the first when they hear the motor turning on.
In case you need more info, please leave a comment.
