    Default _\|Build Log|/_ DIY midi gamepad controller

    hello all,
    (first of all, sorry for my bad english... i'm from portugal)

    i've started my controller project.





    will be based on:

    2 gamepads
    1 sound board
    30 arcade buttons
    2 sliders
    8 knobs
    1 line in
    1 line out

    the box is an old plumber tool box that i've found in a Lisbon flea market



    since this project will have to be as low cost as possible, i've spend some time searching for the correct design (to prevent mistakes) and also good but not expensive components

    at this point i've encontered the first problem...

    keeping in mind that the only experience in electronics that i have is to turn on and off the power button of my pc...

    said that, please be patience, and please sorry for some of my stupid questions...

    so the problem are the LED...

    i've managed to connect the analog potentiometer to the PCB and to a LED, it works fine...




    but when i connect the button the LED light is not bright...



    here you can see what is appening

    what am i doing wrong?

    thanking you in advanced

    You need to find a 5 volt supply. Then you should follow this drawing if possible. It has worked for me in the past.

    I like the idea of having a LED to the pot!

    I'm going to follow this for sure =)
    Why buy something, when you can build it yourself for the double cost?

    I'd like to see what you can do with the supplies.

    Wouldn't you rather spend a couple bucks and get some better buttons etc? The box/suitcase looks rather worn, big and heavy. I mean you can find nice yet cheap plastic project boxes at radioshack.

    Oh wowzer. A plain old bit of moulded plastic, just like 95% of the other electronics I own. How can you not think that box is cool? It has so much character!

    +1 the old box is awesome and unique. Also maybe have a surface on the inside of the box in which you mount all of the pots, sliders, buttons, etc.
    That way the lid of the box still serves as a cover for it and you basically have something that has it's own built in case.

    Also, maybe take a look into replacing those hooks with something a little more stable for keeping the lid on?
