Whiteboard pong

It seems like there is a pre requisite that any technology demo should include pong. It may not be new tech, but we’ve never seen pong played like this. It seems like it could get pretty hectic if it were to be sped up.

    Neat, at first, I thought it was going to be low-tech, like nethack on a whiteboard:

    But it actually looks like a fun game to play… if it were sped up.

    But, what keeps you from just drawing a line around your goal and then just sitting there forever?

  3. Clay says:

    @jeshii The fear of your opponent reaching over and slapping the hell out of you, Then holding you down and marking all over your face with their marker.

    while it may be fun for about a minute, how could you lose at that speed :)

    also i was hoping for the code behind it, or a least a brief description of how its done (language, API’s, hardware etc).

  5. your mom says:

    i wanted to see one of them draw a circle around the ball

  6. Yes, I to want to draw a circle around the ball.

    @clay… LOL!

    This seems like a simpler version of that projector-camera interface where people were playing pong on a table using their cellphones/cucumbers. I think it was posted to hackaday a while ago but can’t seem to find the link for the life of me; does anyone have a link to this project? I’ve been looking for it for quite some time now.

    …so one can only really change the angle of the hit with a curved paddle? The angle detection seems like it could use a little work. Other than that gripe, this is cool sh*t. I look forward to being able to play old-school games on any whiteboard. :P

    This is fake. @ 1:20 the paddle magically changes shape…

  11. nick says:

    @bamrank, yep i saw it too, its a fake…. or they just heavily edited this to make it look “cool”, but i cry fake as well.

  12. veegeezee says:

    the “changing paddle shape” at 1:20 is a compression artifact courtesy of youtube. look closely and you can see a trail of it following the ball there too.

  13. sweavo says:

    please post all “fake” calls to the youtube comments, not here!

  14. Spork says:

    haha, I enjoy the fake comments though they add characters and show that hackers are not knowledgeable about everything computer related.

    Also +1 on the circle comment. What would it do?

  15. heh, i wondered about drawing a circle too.

    they are probably just using hough line detection, so it might just ignore the circle.

    Hey guys, i was the guy that did the coding for it. Im sooo happy it made it to Hackaday! Check out http://www.eness.com.au for more details.

    Hey everyone this is my first post so hello.
    Just a basic question for everyone about webcam online dating
    Why I will need to type personal info or credit card to can access the webcams?
    Is it secure?
    Most of webcam online dating ask 4 credit card and explains that as “Credit Card is required for age verification only. You will never be charged anything!”
    Please tell me about your experiences.
    Also if everyone would name a place or two they dating online, it would be greatly appreciated.
