![]() ![]() I have absolutely zero experience with managing power or using RTC's, SSR's, or Timer IC's and am having trouble choosing which component / methodology to use. right now our best option seems to be setting up some type of separate circuit between the pi and the battery using a combination of the following: RTC, Microcontroller (looking at the Adafruit Trinkit), Solid State Relay, or some kind of Timer IC. We need the pi to turn on at least an hour before daylight to catch early feeders and we don't want the photoresistor to get covered by the snow (we get a lot of snow!). We considered using a photoresistor but would prefer to use something more reliable. The sleep method from the time library in python is a way to suspend execution of the thread your program is running under for a given number of seconds. Open 'nf' file located in, /etc/lightdm/nf Add below line in to SeatDefault (or Seat: in newer LightDM. Now you need to edit your script that's starting X. Our goal is to only run the pi during the day. I used simple steps and it perfectly worked for me: Open a root terminal in raspberry Pi. ![]() ![]() Since the birds we are researching (chickadees) mainly feed during the day we do not need to run the pi at night. Our pi's are going to run off of battery, meaning, we need to conserve as much power as possible. ![]()
