Hey guys, this is my first post here. I've read EVERY SINGLE POST IN THIS THREAD before I started my DDR pad. I was hoping you guys would check it out.

http://www.secondattempt.com/forums/showthread.php?t=57

It's my first attempt at something like this, and it's for the Xbox, but it works perfect. I am so happy.

Thanks for the idea/instructions. I modified some of the details. Instead of foam weather stripping, I bought rubber stripping. And, I bought aluminum sheet metal on accident, so soldering was out of the question, so I had to get creative on adding the wiring to the arrows.

Let me know what you think!!!

Anybody have any ideas about using that 80/20 industrial "erector" set type stuff? Cuz i think that would be a very easy way to get a simple frame set up.....

While considering this method, could anybody tell me how tall the weatherstripping + the lexan and contact are in terms of thickness?

Hey guys, another question from yours truly.

Does anyone know if I were to wire my pad using a PSX controller circuit board for plugging into a PSX/PS2, and I used a PS to X-Box adapter on the controller, would it give me any trouble? I'll probably be buying a universal pad and taking it's control box anyway, but I thought I'd at least check this out. Thanks guys.

Hey, can anyone please p.m. me the document that paster made on how to make the riptide pad have lights?Thanx

Sorry if this has been asked but there are multiple topics and tons of posts to go through. But how much did it end up costing you to make the pad and how long did it take (excluding gather supplies). And if you have tried a Cobalt Flux out...how does it compare?

All right this is my first post so bear with me and if it's not in the right place tell me where it should go.

I was thinking about the sensor mods you three proposed and came up with this idea, if you wanted to mod a manufactured pad, mine being a BNS metal one. You'll retain the sheet metal on metal contact system however what you might want to consider if you want to be economical and use only one piece of lucite or lexan is this: take a piece of sheet metal, puncture it at nine different points forming a square 7 7/8" by 7 7/8"now where the punctures are you use half inch screws, doesn't really matter with the threading, and screw the screws all the way in. thus holding metal in place. Now take another piece of sheet metal apprximately 1" longer, bend the metal at the edges so the top sits but the edges are flat along the sides and screw them down. The reason being for this is so there's more absorbtion from the impact you create with your feet. Solder the control wire (white wire and thick red one), and the ground wire to the sheet, and the current wire (thin red one) to the top metal panel you taped to the lucite.

Well I'd like your opinion on this, and whether or not I should keep it, or salvage what I can from the pad and build a new one.

I have a quick question for both DDRhomepad and Riptide:

How much would you estimate your pad designs weigh? Most storebought metalpads weigh about 40lbs...how do yours compare?

i dont know where the pic is, but heres a good one for lighting your pad:

s1 is your arrow sensor, d1 is your led. t1 is an "npn" transistor. go to radio shack and see if the guy there can help you figure out what stuff you need to get, but from my measly physics, i can tell you at least this:

~ v=ir voltage equals resistance times amperage. your led will have a maximum amperage it can handle before it burns up, so you need the resistor to keep the amperage low. to figure out what resistor you need, plug in the amperage of the led, say 200 milliamps, and the voltage youll be using, 9 volts. 9=i*.02 and solve for i (450). so in this case, you would need a 450 ohm resistor.

get an ultrabright white led for the best effect. if you dont know how to hook up your transistor or anything, pm me and ill help you out.

Knowing my electronics,I have a few problems with your circuit, the "-9V" should probably be labled as 0V or - lead to 9V battery, because someone will think there is 18 volts from point to point. What is S2 doing? just a power on switch I would guess?

also, there's a much more complicated analysis to your circuit...(you didnt look at the drops on the transistor...)
Assuming a standard BJT transistor with a beta of 120 and an official sony playstation controller there will be 2.4mA running through the resistor (I can post the math, but I'm sure noone wants it, if you do, either reply or PM me)

Edit: to be a little more helpful, http://www.lsdiodes.com is a GREAT place to get cheap but good LEDs

...
yea, what he said.

s2 is a power switch, -9v should be 0v, and this is my first ever interaction with a transistor, so i have absolutely no idea what else you just said. note i said measly physics. but i will educate myself before attempting to make one

AHH!!!! TOO MUCH ELECTRONIC TALK!!! BRAIN HURTS!!!! ACK!!!!

yeah....all this complicated talk about lighting is makin me not want lights anymore.

oh one question: since all of the designs suggest adding only two push buttons for start and select on the top right or top left panels of the pad I'm assuming that you guys don't really care about adding a cancel button (triangle)?

im building a ddrhomepad and i was wondering what the dimensions of the pad are when it is finished. also i was wondering if i could get instructions on how to add pushbuttons to the pad so i can add X and triangle. thanks.
