    Ping Pong Ball LED Clock

    I should have been more clear in describing how I soldered the LED's, I did not realize that there are like 4 ways to solder them. I'm glad you got everything working!!

    Ping Pong Ball LED Clock

    hey, awesome that you are building this project :)What do you mean with "SetTime includes '#include <DS3232RTC.h>' which doesn't work when I compile,". what doesn't work? Did you download the library? If not, you should try to do that. they are not interchangeable. here is a link to the instructable I used to set the time: https://www.instructables.com/id/Simple-Guide-to-Setting-Time-on-a-DS3231DS3107DS13/. The code I use is the one reffered to in this instructable, I only changed two pin outs to power the RTC.It is really weird that the RTC starts at 00:00, this should not be happening. does is continue adding minutes after it starts? The DS3232 library works with the DS3231 so that should be fine. Did you connect the RTC to the Arduino in the right way? It could be ups...

It could be upside down.This might be a messy response, but I hope i was able to help you.goodluck!

    That's a great addition.You can also get the room temperature from the ds3231 module, so you could also display that without to much trouble. Your way of changing the time sounds convenient. I think I'll add it as well. I might add a third button to change between some different modes/color schemes/ brightnesses. Sharing of your code would be appreciated!

    Just thought of this, the time resetting could be a sign that there is no power for the ds3231 when not plugged in. make sure to replace the battery if empty, check polarity and connections

    The clock you build looks GREAT! looks even neater than the one I made. What is the thing that connects the power supply to the Arduino? Curious what you did there, so I can improve my own build, since i still don't have a power supply placed at the back yet

    yes, I did something like this, you can add an LDR. since the clock uses HSV colors it is very easy to make the brightness change by changing the V value depending on the brightness. however, this also required buttons to turn off this function if needed. I kinda got it to work, but never actually added it to the clock because I wasn't able to get it to work in the way that I wanted it to. However, once I get to know how the ESP32 works, I might add an LDR. I feel like the way to upgrade this thing is by changing settings on a phone, so i might try that next.

    You are right, a 5V/8A power supply should be more than enough, I originally bought this power supply to power another project that needed more Amps but decided to use it to power this clock.I power the Arduino and the LED-strip with the same v5 from the power supply, everything is just connected in parallel with the power supply. The led strip receives power on both ends from the power supply. the Arduino also receives its power from the power supply. (I think you can also connect the RTC directly to the same 5v from the power supply, but I found it easier to just connect the entire thing to the Arduino.)I hope I was able to help you.

    YESS, this exactly what I wanted to do!! I attached a picture of the board I originally wanted to make to hold the ping pong balls. However, I could not get the holes at .5 mm accuracy, which led to space between balls. Making a board with holes to hold the balls, and using a frame with dado cuts would make this entire project so much more sturdy. (my version is just held together by glue lol)comments / thoughts:-If you made a board with 128 holes for the balls, you can glue them to it from the back (glue between the hole and the ball), making no glue visible from the front.-you can use black acrylic, however, I don't think it matters too much since it is almost not visible.-the LEDs you use are definitely going to make your life a lot easier -if you only need small holes for your LEDs...

( as opposed to common belief, I'm quite sure most newer ping pong balls are not flammable ( are made from plastic instead of celluloid)). - I can't stress enough, finding good looking ping pong balls can really make a difference in how well the final build will look. also if you manage to find balls without a seam, or without a (large) logo printed on them, it will make your life easier.Please send some pictures when your done building this (or of the process). Good luck building!

    Ping Pong Ball LED Clock

    Thanks, feedback like this really make my day and motivates me to make more projects :) I'm really glad I could inspire you. I actually wanted to produce these clocks ( with an CNC and a tool to make grooves this clock can be made way easier and faster) , but unfortunately I don't have the tools, recourses and experience needed to do that. And luckily people do not ask me about my balls all the time, although I did get a reputation as the guy with a huge load of ping-pong balls

    I just placed the power supply on the ground. Im quite sure there would've been a power supply that would've fitted behind the clock since there is quite some space left. This was the first project I made that could not be powered from an usb port, and I decided to just go with a normal power supply to see how it works. I was worried that it might get to hot when placed behind the clock. Also, 10a might have been a little to much, but I'm not sure.

    I'll try making a digital image of the connections. What problems do you have with electrical connections?, I might be able to help you if you could specify what is not working.

    I understand your confusion, the LED strip is placed in an unusual way. I moved one of those images on the page, so it is better visible, to avoid confusion. If any other things remain unclear I'll happily answer any questions.

    Sorry, forgot to add it, I tried adding it right now, but it does not show. I will place it on this page tomorrow

    I entered it, I did not know about contests, thx for the tip :)

    your right, the ping pong balls form horizontal rows, and the led's form vertical rows. each led is still after an individual ball, but it is not placed behind the center of it (added an image on step 8, instead of zig-zag lines, this clock uses straight lines, but it gives an idea on how the LEDs are placed). this, however, can not be seen from the front, since the ping pong balls diffuse the light enough to give the balls one colour. The code up there is indeed very simple) That code will just display the time, and change the colour of the digits slowly whilst doing so. I did not add other code since I'm actually still improving this build. I'd be happy to answer questions if you have any.
