Also, has anybody used a controller similar to this? Can anybody ID it?

Also, when I make the pad itself and I want to ground this thing...I solder a wire to the brackets or contacts and then converge them all into some sort of plug that I plug into a wall? Or am I just totally off base...I can't seem the grasp the concept too well. Any help would be greatly appreciated.

you solder a wire to something metal on your pad, like the corner of a metal square, and wire nut it to the ground wire of an extension cord. put nuts on the other two wires so you dont electrify your pad (and u can use them later for lights). plug the cord into a grounded outlet, ur all set! let me know if this works, its in the theory stages.

That looks a lot like the MadCatz controller that I've used and abused in several previous pad wiring attempts. You'll want to be careful - I've personally gone through two of those, two standard PSX non-dual-shock controllers, and a Dual Shock. I finally managed to get the guts of a softpad, though, and since it's got diodes out the wazoo, hopefully this one will stand up to actual play.

(The previous controllers I used worked for about one minute before they started ghosting, and then stopped responding entirely. Don't let this happen to you - use a softpad control board or ground your pad!)

As an aside, hopefully I'll have a working pad this weekend, just in time to train for our local tournament. E4.gif (See below for shameless plug!)

it dawns on me how substantial soft pad guts are today.

i play 30 minutes on my computer emulator, via homemade parallel port adapter. i unplug the soft pad to store it, and recieve a first degree burn from the static pent up inside the pad. the controller did not fail, lose accuracy, ghost, or fry my homemade adapter. softpads are resilliant to static. if you have problems frying controllers, get a softpad (two for $7 on ebay, plus shipping) and use the guts. not that im discouraging grounding, but the softpads work even with static pent up.

shameless bump: the new logo is for the stepfiles i write, look for them when i post them!

Good evening everybody. I've been reading this thread for awhile now but this is my first post.

I am very interest in making my own pad and acquired a controller from a friend who has no use for it. I really don't know the brand but I have a picture of the inside. If somebody could point out the ground and solder points to me I would be ecstatic.

The picture is located at http://home.comcast.net/~jon237/control.JPG.

Also, for this controller is there an individual ground for each and every button or one ground for the entire controller? Because wiring a seperate ground for each button would be a pain.

Thanks!


See the GIANT black circle in the middle of the pic? That's the ground.

errr....no.
that black circle is an insulating solid meant to protect the controller's main chip. tampering with it will destroy the controller.

to answer the question, yes, there is one common ground...usually. However, after staring at that picture for several minutes, i'm not sure.... usually, the ground circulates around the entire board, making contact with one side of each button before ending in the blacircle. however, yours exits from the black insulation at several points, and there are several soldering nodes.
my advice to you, is DONT SOLDER ANYTHING. first, take a wire, plug in the controller. you see that little metal circle to the left of the down arrow, above and right of the little "3" printed on the board? that is a soldering node, and im almost positive that it is the ground. take a wire, and touch one end to that node and one end to the input (a node that is not connected to the ground circuit). you should get a response. try different combinations. just to be safe, post back with your results....

here is the pic of the controll, there is a common ground plane, which connects all buttons.

Ok two questions???

1. Where does the ground wire hook up to?

2. I heard that the legs on an arcade pad repel shock when u hit the arrow.Is there any way to put legs on a home made pad? If so wat kind and where do u get um? thankx

1. there should be two contact points on each side of a button contact (the golden circle thingy). one is where you solder the actual arrow wire and the other is where you can solder all 4 of your ground wires. since the ground is connected to EVERYTHING in the controller you can solder them all at the same spot. just solder the 4 ground wires to a spare wire and then solder the other end of the spare wire to the ground.

2. i wouldn't recommend putting legs on your pad just from experience from manufacturely built pads. if you elevate them on just the corners of the pad it'll warp in the center. besides i don't think putting legs on a pad will decrease shock. i don't feel any "shock" to begin with when stepping, even stomping on an arrow. if u just play on the front of your feet it shouldn't be a problem.

i already have a planned doubles attachment to keep them from sliding apart.

trunk latches (example). just slide the pads next to each other and clip them down.

ok this seems like a stupid question but im going to ask anyway. the only "foam core" i could find in wal mart were " foamies sheets" . they are 2 mm thick, which im pretty sure is coming up short on the 3/16 '' measurement. now, my question is, should i use it anyway? will it make that much of a difference?

Hey guys, I've been making progress on my pad, and am to the point where I'm ready to start the wiring/soldering process. I'm using DDRHomepad's design, but I have absolutely no knowledge of electrical engineering. Can someone elaborate for me a little what is done for wiring with the DDRH design? For my arrows, from top to bottom, this is what I understand: Lucite/graphic/lucite/metal/wire contacts?/weatherstripping and foam core/metal/pegboard/rails. Is this correct? If so, then what exactly comes with the wire contacts? I've seen pictures, but they all look different, and I can't seem to figure out which is which and what goes where. Can someone point me in the right direction? Thanks! riiight.gif

ulala, to put it simply:

theres a wire attached (soldered or taped or whatever) to the metal on the lucite, and a wire attached to the metal on the base. one of these wires, it doesnt matter which, goes the the common ground on your controller, along with all the other grounds. the other wire, from the other contact, goes to the individual button contact on the controller. when these two contacts touch, its like pressing the button, so you have one wire on one side and one on the other. i hope this helps!

if it doesnt, ill be making a video within the next month (i dunno if you can wait that long) about soldering a controller, because so many ppl ask about it.

i take it the foam is for softening sound? that or for some use in ddrhomepad's design which i know nothing about. riiight.gif if it's about softening sound i think just adding rags in unused space under the arrow helps.
