Recreating Pong

roonlulz
roonlulz over 5 years ago

Hi, I do not know if this is the right area to post this if it is not I am sorry. I am pretty new to the single board computers and trying to recreate Pong without using programming. Not looking for an answer on how to do it more of a answer of where to start learning on how to accomplish this, such as generating an image onto a screen using different logic chips with hsync and vsync.

    That reminds me that I have a Pong game that I built many many years ago using the LSI IC that is referenced in the article. I think it’s sitting in a junk box somewhere. I never did build a case for it…

    I recall that there was a blog on Adafruit last year about recreating Pong on 74series logic. PONG: making a game with 74 series logic https://blog.adafruit.com/2019/04/08/pong-making-a-game-with-74-series…

    Sounds like fun and I guess that would fit with the overall theme of the workshop?? A quick look through my accessible junk didn't turn up the old game so maybe I'll have to wait for your PYNQ implementation…

    If you really have a lot of lockdown time on your hands, how about analogue pong ?

     

    Rules would be, no counters or shift registers or logic more complex than that.

     

    Inputs are easy - two pots giving voltages.

     

    The ball position can be represented by two time varying analogue signals, one for X and one for Y. A window comparator will tell you if the ball hit the bat.

     

    If you use integrators to make the X and Y signals the bounce needs a sample-invert-gain-hold (fancy maths not required)

     

    Any one tempted ?

    "...how about analogue pong ?..."

    Output displayed on an analogue oscilloscope in XY mode ?

    I'd accept that, but it might not be too easy because of the  paddles.

     

    Do scopes in XY mode accept Z modulation of any kind ?
