My giant SNES pad with original pad for scale reference |
I had originally planned to make the size an even 10:1 scale but after doing the math, I realized the resulting pad would be over 6 feet across and wouldn't be practical to actually use (i.e., like most of the other oversized gamepad projects floating around online). I had chosen 10:1 because SNES pad buttons are right at 10 mm in diameter and you can purchase humongous 100 mm arcade buttons on Amazon/eBay, but they also sell 60 mm buttons, which results in a much more reasonable 6:1 scale.
I found this dimensioned image online but it seems to have disappeared so I'll rehost it for others to benefit from. |
And here's what it looks like all wired up:
The only part I didn't make myself is the actual controller port plug, which I took from a newly manufactured SNES extension cable.
I used terminal blocks to make it easier to swap things out in the future and to reduce strain on the breadboard connections, which are the weakest link in the chain. The terminal blocks also came with bridges (the red-rubber thing on the one at the bottom-left of the image) that were useful when running voltage lines out to the button LEDs.
I left the back open and just built a little frame around the wiring. I may go back and put acrylic or another piece of wood over it, but I'm okay with it as is for now:
You can also see the L and R shoulder buttons, which are just the same 60 mm buttons used for the face buttons (the button sets come with 5 buttons and I ordered one additional one for a couple of extra bucks on eBay). The dpad buttons are also 60 mm buttons, but they're flat instead of convex:
Testing the button LEDs. You can get a good look at the flat dpad buttons. Still lacking some of the paint, as well. |
Some day, I may go back and fabricate a small dpad to lay over the individual buttons and/or rig up something over the start/select buttons, but I doubt it, since they work fine already.
Anyway, here's my 3-yr old daughter and me playing some Donkey Kong Country on it:
She still doesn't really get video games, and her fine motor skills aren't really good enough for a standard-sized gamepad (which isn't really designed for her toddler-hands anyway), but she likes pushing the buttons on the oversized pad and having me control movement lets her focus on a single action, like jumping. I can also call out the color of the button she needs to press, which helps her work on her color mastery.
Anyway, that's it. If you have any questions, hit me up in the comments.
Trully awesome project!
