    Default Word Clock

    I would really like to build a Word Clock. Of all the projects online this seems to be the best
    https://www.jeremyblum.com/2016/02/03/wordclock/

    I am way over my head when it comes any coding that might be needed - but feel his files would get me going. The built will be no problem for me.
    My question is could I use Ron's Pi Hat adapter https://ronsholidaylights.com/raspbe...atrix-adapter/ instead of this one https://www.adafruit.com/product/2345 and still have it work?

    The other item would how to at the RTC https://www.adafruit.com/product/3296 to the Pi?

    Suggestions?

    So.... word clocks are a hobby of mine.

    If you are interested, and clever, I have PCBs of the Clock3jr available.
    Here is the info for it...

    Also.... I have my version of Ri's pi adapter available as a bare PCB for only $1.50.

    That RTC you note from adafruit is available at aliespress for about $1. Its very common.

    PM me if you would like more info

    Thanks but I am interested in using P10 panels - but your clocks are beautiful.

    As long as your P10 panels use the HUB75 interface then you should be able to use Ron's adapter. You may have to change the PIN numbers in the Python code because the adafruit hat uses a different set of pins I believe. The library we use for FPP supports the adafruit pinout as well as the better pinout that is on Ron's hat and other hats available from others.

    You do need to make sure that the panel you are getting does not use the "E" address line. I don't think that will be an issue on the 32x32 panels. As far as I know, none of the hats we use for driving panels with FPP support the E address line.

    Thanks Captain

    I was planning on using the same (extra) 32X16 panels I used on my matrix - which were purchased form https://www.crockettfantasyoflights....matrix-panels/.

    I am assuming they use the HUB75 - from what my connectors look like. Where will I find the E address line - in the code?

    This is an awesome idea. I had never really seen these before. I have wanted to make a desk clock using nixie tubes, but this would be a great option as well. Another plan I have is to make a smart mirror in my mudroom that will use a raspberry pi to show the weather, and events from a specific calendar my wife and I share. kinda like this : https://www.youtube.com/watch?v=fkVBAcvbrjU . The cool thing is I work for a company that make car mirrors, and one the interior mirrors we make is reflective until there is a screen behind it. should be able to get a panel for a build like this. shown a few seconds into this corny video... https://www.youtube.com/watch?v=xQF-rz6qELc

    If you are using those then you shouldn't have anything to worry about. They don't use the E line. You will have to remap the pins slightly in the Python code to work with the Pi Hat though since the adafruit pinout is different. If you look at https://github.com/hzeller you can look in the RPI matrix repository and there is a diagram showing the pinout that the Pi library uses. The Pi hats that we use with FPP are using that optimized pinout that is what the library calls "standard". The library also supports a "classic" pinout which wasn't as efficient and only supported one chain of panels, and it supports the adafruit pinout as well. These are compile time options for the library, so it supports one or the other but only with a recompile.
