    I made this tonight. It's stupid but fun :) It automatically presses the A button over and over again on a Nintendo 3DS.

    Mk II Update:

    I have replaced the K'Nex rods which were pushing down on the A button with a column of bricks. I did this because the K'Nex rods were too narrow and would sometimes move around inside the channel which led to the A button, causing them to go out of alignment and fail to trigger properly. I put a smooth piece on top of the column of bricks so the axel glides over the top. Doing this allowed me to also shorten the channel leading to the A button and therefore make the arrangement of the gears a bit neater. It is now 100% reliable and never fails to trigger. I've ground through 600 playcoins this morning without any interaction (other than starting it off and resetting the playcoin count to 300 between runs).

    MK I:

    The gears slow down the rate of button presses:

    The final axel presses down on a rod inside the chimney part which is positioned over the A button:

    So for every rotation of the axel, the A button will be pressed once. There's also a brick behind the R button to make the animation run faster:

    (Sorry for the disgusting condition of the grey baseplate in that picture. It's the only one I had spare and I got it in some Lego someone gave me - none of my own Lego would be in that condition...)

    I want to add a potentiometer so I can get better control of the speed of the motor. Here's a video of it running:

    I just love to see the most amazing and peculiar ideas you come up with, @mashers! They're just so amazing and enjoyable to see! :lol:
    It's funny, because when I was very little, I had the same idea with my DS Lite! :D

    Absolutely genius.
    I agree, maybe something that allows you to go to Lumiose with a full party of eggs, and then does the work for you :P

    Yeah because the coin trick kind of damages the stick.

    Thanks guys :D I need a bigger gear for this as I would prefer each puzzle piece to require one revolution of the gear and have two cams for triggering the A button. That way it only presses it twice for each puzzle piece. The reason for this is I'm slightly worried about the effect on my A button of pressing it so many times!

    As for making one for the circle pad for Pokemon, the difficulty there would be with getting anything to attach to the circle pad or to move precisely enough to slide it. Can the d pad be used instead?

    Well, all it really needs to do is hold one direction XD.

    Oh, so you just hold down on the d-pad? Can't you just put something on top of the button and then put a book on it? :P

    Yes, but you'd need to position the thing over the B button instead since it asks if you want to name the pokemon, and if you press A you go into the naming screen.

    Awesome work here. You're now ready to play Fantasy Life's story mode where you use the A button more often to skip stupid text than to really play :P

    Add a book on top of it. The lego brick is for the precise pressing, the book for weight.

    Seems stupidly useful, especially if you were to use the play coin hack with it.
