I just stripped back the plastic coating a little way from all 4 black cables and wrapped the wires all together to form one.

I only used one of the four wires - if you have a Sanwa joystick that uses a circuit board, the ground is connected to all of them that way, so one is all you need.

Allow me to preface my reply by saying I am a complete novice with electronics.

I have the Sanwa JLF-TP-8Y, but I was thinking, surely the flow of info along the wires is from the joystick to the iCade, not the other way around? So, the joystick may well be creating a ground signal for each direction and sending it along one wire, but doesnt that wire need to feed those ground signals to the four black wires that connect to the iCades own circuit board?

To be completely honest I don't really understand what the ground signal does anyway, but to me it doesn't make sense that only one of the iCades four black wires need to be connected to the one that comes out the Sanwa.

Any explanation appreciated

As we cant be certain what the icade circuitry board needs, and even though it might work with only 1 connected, it might still be safer to twist them all together. But i'm not an electrician so i'll leave it up to someone else to explain whether it matters one way or the other.

Well, time for a bit of electronics

Basically, the button or each switch in the stick is a... well, switch.

Ground is, well, the ground: it has 0V, it's why this works (it's been a while, but basically, 3V DC cable by itself = no current flow, 3V vs. GND (0V), there is a difference, current flow).

Joining all ground cables is useless, as you're attaching 0V with other 0V. Actually, if the ground is not totally 0V, you're adding those values and reducing the difference.
On the stick PCB, the ground is one copper track, so all its switches have the same ground value.

That's why one black cable is enough.

edit: and controllers/peripherals never have ground by themselves, except when battery-powered. And they just use the minus part of the battery.
Even your iPhone/iPad uses the computer's ground while it is charging (the 30-pin connector has a GND pin).

Carpentry part of full MAME conversion is almost done. Monitor bezel & marquee done. Back & base done. Just gotta do the following to the new speaker shelf (between monitor bezel & marquee) when the speakers (x2) arrive tomorrow. Basically, going to drill two holes in the shelf, cut in half, paint & join back together again around the speakers.



Then get some new vinyl cut (existing is ruined), fit monitor, PC and other bits n' pieces.

Paradise Arcade shop

Has anyone here dealt with this outlet?

I ordered parts from them last Monday and still have not received my order or even a shipping notice. Email Friday and phone call Saturday have not been returned. Everything I ordered was listed as being in stock, so I'm kinda wondering what the holdup might be.

I ordered from Paradise, and while I do not remember the exact dates, communication was great and I received everything I ordered, well-packed, with some chocolate macadamia nuts as a bonus!

As for the ground wire thing, yep - imagine all four switches' ground terminal connecting to the same metal 'plane' on the joystick's (as well as the bluetooth controller's) circuit board. Connecting each black wire, in that case, would actually be redundant (like shaking someone's hand, foot, head, and ... belly instead of shaking their hand when you meet them).

I was thinking of adding some stereo speakers to the iCade, too ... but really have no clue if I ever will since they'd require power and all that. Hmm...

Hi!

Just finished my iCade-mod and wanted to share it with you guys.

I added buttons to the left and right side of the iCade, perfect for pinball-games. I added two on each side, so I can also play the various pinball-mini-games with the side-buttons.

Here's a video of my girlfriend playing Zen Pinball: http://www.youtube.com/watch?v=hCb-1...e_gdata_player

I attached two pictures to the post. Let me know what you think.

Thanks.

The lack of communication was what I had a problem with. He finally emailed me on Monday and shipped Thursday. Hoping stuff arrives Monday. Jealous of all you guys with your upgraded machines.
