|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.

:smiley:

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 =)

It’s pretty easy, follow the tutorial here.

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.

Dude! What are you on about? That old box is way cooler than any crappy bit of plastic. You need some style man :stuck_out_tongue:

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?

If your so closed minded to suggestions why even post? Sure it looks great hopes all is well blah blah blah.

I’d say that suggesting a plastic box instead of a vintage toolbox was closed minded :roll_eyes:

W/e, I’m over this. I’m just saying there is no need to bash a suggestion. I’m just trying to help, no harm intended. Hope your midi turns out nice.

I never imagined that the box would lead to this big debate…

I’ve chosen the box precisely by the character, its history, I do not want a plastic thing without a soul …

and it will be very good looking when it’s finished

Archie, thanks for the sketch, I’ll try to see if I can get it to work

Should go for wooden buttons and knobs :smiley:

Best place to find 5v is on the incoming cable. Good luck.

i’ve found it…

:smiley:

great, it works great…

there’s a contact on the pcb, but in the cable there is a more “clean” connection

thanks archie

nop…

:wink:

Love the old antique looking case dude even though personally i do prefer metal casing mainly because im an animal on gear:L

the old box gives it a very retro feel so retro all most an antique feel lol love it

The retro style is kool!

Good luck with all your gamepad soldering :slight_smile:
