2-4-8-way switcher for 8-way-joysticks

<< < (4/9) > >>

I'll vouch for Bencao74 and this product. He's a solid modder and this would be tremendously useful for MAME players who want to keep flexibility of their joystick without having to physically restrict their joysticks with gates etc...  :cheers:

Bender:
MAME already does this for analog sticks don't know how it handles digital
but no other emulators or consoles can do that analog or digital
I can't wait to but one on my xbox360 stick
Still would like a review from someone here, or Maybe I'lll just bite the bullet and do one :dunno

Aghhh I just thought of something else this would ROCK for Tron: 4 way lightcycles and tanks, 8way for spiders and cones  :cheers: just a press of a button in between!

EDIT: I bought a couple. I'll post my reactions when I get one set up

Ahh so thats what it is.  :)

I had seen the teaser on the arcadeshop.de front page and I was wondering what it was.

Something I've been curious about is if anyone is doing this same action with a SPTT (single pole triple throw) switch.  You could also use a rotary switch taken out of an old printer or serial port switch box or even three SPST toggle switches.  To help here are a few drawings of the idea, typical application would be a Happs' Super with actuator set for 8 way action:
The first drawing is basic joystick wiring for joystick with cherry microswitches (sorry, haven't figured out a way to do this with leaf switches).  If the joystick physically allows 8 way action then that is what the output will be.

Second drawing is the idea of making the 8 way joystick only report one direction at a time by making the ground conditional.  Example:  With this wiring if the UP button is closed then the ground is removed from the remaining three switches so they can not send a signal.  Even if UP and LEFT are both closed the only signal sent will be UP, since there is no ground reaching the LEFT switch no signal can be sent from it.  If DOWN and RIGHT are both closed the only signal that will be sent is DOWN, again there is no ground reaching the RIGHT switch so no signal will be sent.

Third drawing is the arrangement similar to above except the triple pole switch has been added as a way to optionally provide ground to the three switches (DOWN, LEFT, RIGHT).  The switch is open so no ground is reaching these switches other than the conditional grounds, joystick would still function in 4 way mode.

Fourth drawing is the arrangement with the triple pole switch in the closed position, all four switches have direct ground so all can send signals, joystick would be 8 way action.  It is key that the 3 lines coming out of the multi-ground switch do not touch each other on the way to the joystick, they need to be isolated or your will lose the benefit of the 4/8 switch.


I have not tried this on my system yet, just something I have been thinking about.  There are definite limitations, won't work for sticks with leaf switches and would need to spend some time figuring out best order of switches.

* If this is in the wrong area please feel free to move. *

Ideas always hit after you post...I'll leave the original up to show the evolution of the idea.

Here's a wiring diagram that only requires a $2 SPST toggle switch to jump from 4 to 8 way action.  The arrangement of the switches is critical, when put in 8 way mode (SPST closed) both UP & Down share a conditional ground and LEFT & RIGHT share a conditional ground.  The conditional ground in this arrangement is not an issue since in theory you can not hit UP and DOWN at the same time or LEFT and RIGHT at the same time.  Same limitations as above apply, no good for leaf switches, etc.  Not trying to take away from anyone's offerings, only put this out here since this is a DIY board and curious if the idea would work.
