Pong clocks using LED matrix modules

We love Pong clocks because they’re showpieces. This particular offering, called the Wise Clock, is the third hardware revision of the project. The LED display is dead simple since they’re using a 32×16 bi-color module from Sure Electronics. If you don’t want to design and build your own multiplexing display this is a somewhat inexpensive and high-performance alternative.

After the break you can see that the paddle movements look very realistic. They move like a human player might, which is quite often not the case with these clocks. If you want to see how that’s done, check out the code which was originally developed by [123led] for a different project.

    Definitely one of my favorite clock hacks. This and the pong watch. I just like the pong clock concept. Now if they could combine the two.. Led-matrix-pong-watch-game!

    nice work ;-) … now that i’ve seen it I really want to build one for myself though it doesn’t seem that i’ll have the time for it in the foreseeable future :-(

    Love it!

    I love the “realistic” movements, which in this case just means a paddle doesn’t start to move much until the ball is being passed back to it. I just get tired of the generic “pong animation” where a ball is passed back and forth and both paddles smoothly follow the ball the entire time – boring. I’m sure the algorithm in this could be tweaked a little bit to make it more realistic. He could make the ball speed up as play time increases and make the player movements more snappy and erratic as the ball gets faster, until one paddle loses.

    That is one of the coolest things have I have seen in ages.

    Mad props to the builder for getting the paddle action right :D

    I like the detail that the minutes side scored on the minute change.

    This is very cool. Thanks!

    That really is very nicely done.

    Love the way the watch is actually score table which really works

    This is awesome and would make a neat gadget to put on my office desk. Looks like I got some parts shopping to do!
