    Default Raspberry Pi - Kits and recommended purchasing packs

    From the Pi Day thread:

    Joe recommends that everyone start with a Rasberry Pi 2. The 8GB CanaKit on Amazon is the simplest start.

    Amazon.com: CanaKit Raspberry Pi 2 Complete Starter Kit (9-Items): Computers & Accessories

    Please post a response here with other kits or pieces/parts lists that you would recommend that someone purchase if they are just getting into Pi for the first time.

    Thanks!!

    I know we discussed this clock but I could not quickly find the information. Is there a real need for this or will all the Pi Players stay in sync without it ?

    You do not need a clock if your master pi connects to the internet so it can get time because the master is the only Pi that needs to know the time for scheduling. All remote Pi's just do what they are told when they are told by the master.

    I got a clock in case I wanted to not have any Pi connected to the internet. For this I would just put the RasClock on the master Pi.

    @kidcole if you are going set up your system like @Tripplett and most of us, where the master is on your home internet router then you don't need a clock mod. Only the master needs to know the time to set your schedule. The only time you need a clock mod for xmas lights is when you want to have a show schedule but do not want your master connected to your home internet or for some reason your master was too far to access the internet.

    @EricR Personally I want my show network isolated from my home network and the internet. My plan is to have a wired connection between my FPP Master/Slaves and all the controllers. The Master FPP will have a wireless USB dongle to sync time from the internet. If your Internet connection goes down (as mine does from time to time on TWC) then you dont have a clock source to sync from. For $8, I think having a real-time clock with battery backup is a good thing.

    Again, my $.02. ;-) LOL

    Sorry Denny, they changed the silly URL over the weekend.
    LINK

    I have a screen capture of the page, but not sure where to upload it here on this site. It's 3mb in size.

    The only time you would have a problem is if your internet went down AND you lost power. As long as you don't shut your Pi down it won't loose the time. Mine stayed up for two months with no internet access and never lost the time. I didn't have it connected to my home via wifi. I will in the future. So if I loose power it will re-sync time as long as the Internet comes back too.

    That said I think these Ras clocks are a good idea for your master.
    Thanks FrankP thanked for this post

    If you add one of these to your master, will it still get the RTC data from the internet? (Assuming you have it connected to your home wifi.) Do you have to perform all the various scripts that are on the instructions page if you purchase one? Can we do that if the RPi is running FPP's version of the OS?

    Yes, if a Pi has a Real Time Clock chip (RTC) it will still try to check with a web Network Time Protocol server (NTP) to update its clock on a schedule. I can't remember what that schedule is.

    EDIT - it checks every 1,000 seconds.

    I'm not following your comments on scripts. I haven't run one yet but I thought all that was required was to pick it from the drop down in the FPP's setting menu. I know there is a place to select it somewhere.

    EDIT - I found a post from Cpt Murdock mentioning that if you have an Octoscroller with a RTC on a BBB (and I do) that you can point your master at the BBB Remote for time. Essentially defining the NTP server for the Master as the BBB Pi.

    It should just be a drop down option in the FPP settings. I am waiting on the clock battery to be delivered and then I will let you know.

    In that link, there are instructions with 8-9 steps on how to enable the RTC using commands on the command line for raspbian pi. If it's just a drop down choice in the FPP software, that's great!!
