No, I havn't, but Thursday I am working with my dad on the wiring.

Just one question, were DDR/SOLO/etc pads wired in series or parallel?

From that answer we will work on a solution. E4.gif


Very much in parallel. The operator menu can give you a testing screen where it shows you exactly which sensors in a panel are registering when you step on an arrow.

Update on my gamepad:

The parallel wiring of my sensors is beginning to work out a LOT better, partly because of adjusting to the pads/shoes game play differences, now the problem is this: I have foam on each side of the sensors, and lining the sides of the arrow well, the foam of which is slightly higher than the sensor. Some problems that still need to be overcome:

- Stepping harder than what feels normal.

- Freeze holds not very good - most of the time I have to "bounce" a-la crap-tastic EXTREME machines, and even then it doesn't always save the freeze, once or twice on long streams they hold perfectly, on small freezes they hold but begin to give way.

- Flickering - constant firing at random intervals

How can I do this WITHOUT removing my parallel wiring w/2 sensor/arrow setup? I am now getting more greats than goods/boos/misses, and more perfects than greats, but it isn't there just yet.

The need to step harder along with the freeze arrows being hard to hold are most likely the same problem. The foam sounds like it's making it a lot harder to make the sensor register if it's higher than the sensors. The sensors should be very close to if not flush with the arrow panels themselves.

Flickering is trickier to isolate. Does it happen with only one arrow? It's usually caused by a case of a single sensor somewhere being jammed or oversensitive.

a little off topic but I found an interesting concept for a non-mechanical pad:

Soo...

The arrow panel on my tx-1501 cracked... [yes i know this pad sucks]

I was wondering if you guys had an answer to a question i have.

Can I just cut out a square of plexiglass and glue some sheet metal under it and use it as an arrow?

Yes, infact you should replace all of the sensors with sheet metal. If you have the money use lexan polycarbonate.

Anyways,

Do you know where I could buy sheets of lexan or acrylic?
+ the average price of them?

Click Here for the ebay seller that i'm going to be buying from

He has really cheap prices and good shipping rates... i linked to the listing you'll most likely use to build a pad, but check out his store for more sizes/quantities

yeah they do... but in the sizes you need at a decent price? most likely not... it doesn't hurt to check of course.

i found that the stuff they carry is mostly just for windows and crap...

I googled it and thats all i found -_-

Anyone ever tried sheet metal arrows?
Seems like it would work okay as long as it was flexible and could bend back into pace..

Soo...

This guy on ebay is willing to cut the lexan for me to 1/8" by 10 7/8" by 10 7/8"

These are the exact demensions of the arrows on my pad.

But I've heard acrylic [material that my arrows are now] are more stiff then lexan.

Would the lexan being too flexible interfere with anything?

I thought Lexan was less flexible than acrylic.

lexan and acrylic will both work fine... you wont be able to tell the difference between them. 1/8" is really thin though... you should go with at least 1/4" if possible.

Wow,

I'm assuming you've never had a broken arrow.

Ive recently built a pad using the Riptide body design using the matrix sensor design. Though i've run into a problem with the sensors.

What ive done is ive used foam tape (single side adhesive) on both the mending plates and placed electrical tape under one sensor plate, screwed it down, placed the top plate on top of the bottom plate and folded the electrical tape over that plate.

That isn't working since the pressure that the plexiglass (or perspex in Australia) gets ends up pushing the two plates apart which then causes some weird issues with the arrows registering and etc.

What i want to know is if there is a cheap/easy yet effective way of keeping that top plate in place for a very long time. The only thing i can think of is using some double side adhesive tape in between the two sensor plates but i'm not sure how long thats going to last. If anyone has any thoughts i would appreciate it.

P.S. I apologize if this has been mentioned/solved before, i don't really feel like reading the 301 pages of this topic and searching for this has yielded nothing.

a pic would help but it sounds like you have your sensors set up right. not sure about the foam tape thing though. are you using that as your "mousepad" (thing to give rebound)?

the sensors themselves shouldn't be moving much, so they shouldnt really be separating themselves.... How much vertical and horizontal travel do your arrows have? ie, how far do they go down when you press them and how much do they wiggle around under the corner brackets? You might have too much "play" in them and need to adjust accordingly (adjust corner brackets in, add washers, whatever.)

Other than that, I think I remember reading you could use duct tape instead of electrical tape. that might give you some additional strength ....
