    if you were going mass market, then you would be better off building a custom circuit board and case. I would checkout arduboy www.arduboy.com as its kind of already done for you and it's open source.

    DIY Game & Watch

    Thanks for you interest. The demo board I used does not seem to be available any more, but it was just an 18f4550 on a pcb ready built. A similar part you can use is based on the 18f2550 have a search on ebay for "pic18f2550 proto" or "startusb" and compile the code using Microchips MPLAB software which is free to download. You might have to re-program parts of it to work with the new hardware. You do have to know what you are doing to get this to work, don't expect to be able to just copy everything and it will just work. I'm hoping you have some sort of electronic engineering experience.You could also do this on an Arduino and "Arduino nanos" are plentiful on ebay, but you will have to re-write the code for the hardware which shouldn't be a problem if you...see more »Thanks for you interest.

The Arduino compiler seems to have all the hard stuff taken care of so you might find this easier. My background is PIC and so I haven't done any Arduino projects, but I have been using one more lately and development hardware does seem to be more plentiful. Maybe its time for me to make the switch.I drew the graphics in MS paint, saved as bitmaps and converted to data using lcd-image-converter. Google it.The case is just something you have to wait for to turn up. I have an old Mikey Mouse Game & Watch with a smashed screen I bought from ebay, but paid almost £20 for it. I have a colour screen to put into this one and was thinking of using a PIC32 board for that, but maybe I should switch to arduino - If I ever get round to it.:-)Cheers,Andrew

    And a quick search on ebay, and I find them already built with LEDs. Amazing!

    Very Ingenious. I must have a go at building one of these.

    Well, I made use of the 12v supply so 12v would be a good place to start. but as it's normally a dc motor that is driving the gears then 12v-15v will do.
