      The device looks interesting. Is it going to be an open platform? Can one write further games for it or do you plan some? I am just thinking about some 4player pacman (who gets most points) or a multiplayer snake (last man standing). To control those I need not the absolut position of the rotating knob, but its change. I do not know if this is possible with the controls of the prototype.

      Count me in. Looks like fun.

      Hi Bradley,
      with the standalone clock I mean something like this…

      I'd definitely get if it was built with ESP8266 because it had a huge hackability possibility.

      Thanks again for the comments guys.

      @Giovanni - I'll certainly be looking into having a Arduino Uno spot so anyone who wants to, can plug their Uno into it and experiment with it that way. I'll also give a few tutorials to help people get started with using an Arduino with the display - The Adafruit library works well with these.

      @Bernd - do you mean a real time clock so it can display the time? Also for stand alone play - do you mean have a computer player to play against?

      Looks good!
      A stand alone play mode with realtime clock make the board nearly perfect.

      Super. I want it!!

      Go for it!

      Leave the possibility of programming the led matrix (in Arduino? Neopixel library). If I want use the rgb matrix with a library, I can use this device also as a screen or tutorial kit.

      Thanks for all the comments guys.

      I was looking into a battery option however that comes with shipping restrictions which at the very least would bump up the price of shipping simply because it contains a battery. I am doing more research on this however. The rotary encoder was a thought that crossed my mind however it would make the game more difficult to play since there are 25 spaces that a player can move between the left and right of their screen. This means the rotary encoder would need 25 clicks to go from one extreme to the next and this can't be achieved with one 360degree rotation. A potentiometer however can achieve this within its 270degree arc.

      There are buttons for each player but at the moment they only serve as a 'pause' button. I had them their just in case I came up with a brilliant idea for them - that hasn't occured yet...

      I can try and include sound FX perhaps however the microcontroller is quite busy refreshing the LED display. But there could be room for it to play a few blips and beeps etc...

      That Retroball game always looked like a great game!.. Obviously I will always back you're Projects so I'm in Brad..
      I do like the suggestion of using a DIP IC socket though, that way we could use a Microchip with more flash memory.
      Do I see a button for each player too on the board??

      I saw the price and was all set to say go ahead but I can't afford it. then I watched the video and I'd be hard-pressed not to back the project. It's outside of my impulse buy price range but it looks amazing (I'm not saying the kit is not worth it, just that I'm particularly price-sensitive at the moment). Pity it won't come with the music - maybe sound can be an upgrade or stretch goal. A Micro-usb socked might be preferable from a power compatibility standpoint.

    15. Russell Calbert

      I'll back this, but a couple of suggestions. How about a 18650 li-po + charger. and rotary encoders rather than pots.

    16. Ian Kelly on

      This is a great idea. I'm with PM Adams here in that a sliding potentiometer would be better.
      I notice that there is a USB cable connected to it whilst playing, I assume this is to provide power only, Could it be powered by internal LiPo batteries charged by the USB connector and have the possibility of being powered by an external mains power adaptor.

    17. Gregor Zajutro on

      Brad, great idea. Count me in!

    18. Bradley Slattery 7-time creator on

      @PM Adams

      Great idea, however I looked into this option a while back and in the heat of game play, the slide potentiometers are very prone to breaking due to a player rushing to get the ball that is all the way over in one corner.

      I'm in ... Due to the nature of pong, you may consider a slide potentiometer.

      @Douglas, great to see you like the project - I have wanted to make it as easy to build as possible, compared to the old single color version :)

      @Daniel - great to have your support!

      @Jaap, it would have an ICSP connector so you could reprogram it with basically any programming language that you like, that supports a PIC18F43K20 microcontroller.

      @Lucas - I think the IC socket idea is good, rather than solder the microcontroller in directly. the microcontroller however will come pre-programmed with the Retroball code on there.

      I would back this, but if you are going to do it as a solder together kit then it would be great if you did it so that it was a nice project for someone learning electronics who wanted to make something a bit more substantial, i.e. ic components in sockets, source code on git etc.

    23. Jaap Scherphuis on

      I'd buy one for sure. It would be especially awesome if it were reprogrammable like the Digirule.

    24. Bradley Slattery 7-time creator on

      @Colby - I apologise that this update has offended you. I'll send you a private message via Kickstarter.

    25. Daniel Richert

      It seems to me this is very good idea. I would back one.

    26. Douglas Cameron

      Brad, I had been drooling over this project over at you website. I was over looking because I was wondering whether you had anything in the pipeline... so, count me in.
