At $599 I can't see them moving very many of them. -S |

I have been unable to contact Sean. His phone says, "At the subscriber's request, this number does not accept incomming calls" Um.... He is pretty far away in his new place, and even when we agree on a time to meet, it has been 50/50 that he is actually there. Anyone have an alternate number for Sean? |

Wow, my apologies for not seeing this thread earlier. |

Ok hard to follow all of these posts, but looks like you are still in the design layout stage. I like the layout, looks pretty cool. I would suggest you look at a mouth controller similar to what we did on Bspill's. You don't have to compromise that way and will get nearly full functionality. If the game doesn't need the shoulder buttons you don't even need to hook the mouth controller up if the circuit is designed correctly. Here are my 2 biggest recommendations as they caused us the most difficulty. 1. Find a PS2 controller with large solder pads. Just makes the electronic work easier. 2. Find a PS2 controller that is looking for 100k Ohm potentiometers in the analog sticks. I can't stress how important item 2 will be. If you are really good with a soldering iron the pad size can be worked around, but the resistance of the potentiometers can be a show stopper. The official PS2 controllers use 10k Ohm potentiometers for their analog sticks. Unless you have very good connections with an electronics supply house you can not get 10k Ohm pots for the Happ Analog joysticks. The Happ sticks have a choice of 5k Ohm or 100k Ohm pots. 5k is (or at least was) the standard for arcade games. 100k Ohm is what you will find in PC analog controllers. These pots are special and you aren't going to find replacements at Radio Shack. They are High Life meaning they will taking being turned a couple million times vs. the normal ones that are only rated between 5000 and 20,000 times. The other special thing about them is that they only have 50 degrees of electrical rotation. Meaning that as you turn from 0 to 360 degrees the resistance only changes from 155 degrees to 205 degrees. So in the case of a 10k ohm pot 0-155 degrees = 0k resistance, and from 205 to 360 degrees it's 10k ohms. At 180 it's at 5k Ohm and gradiant in the rest of the range from 155-205. You will NOT find a replacement for the controller if you use 10k Ohm. I managed to have some special made in Taiwan or something like that. So you can pay $45/resistor and remember you need 2 per joystick and you will need to order at least 100 or more for them to do the special order. You do the math. In quantities of 1000 or more then you can get them for $5-$10/resistor and the price keeps going down once you get into the multiple 1000 order. I only needed 2, so I almost scrapped the idea of the analog stick before I got lucky and talked an electronics manufacturer into getting me a "sample" of these made for free, (they had them made by hand in Taiwan) but that process took me about 2+ months to get it resolved and they were under the impression that there was a potential of this becoming a commercially available item and a subsequent large order would potentially be following once the prototypes were finished. Bottom line find a controller that is looking for 100k Ohms, they are out there as I realized when I bought a different controller for a different project. This way you have the option of ordering the Happ with 100k pots or even using PC arcade analog stick as they also use 100k pots which would save you a ton of money in the short run if you can figure out how to mount them. Bspill and I went with the analog stick from Happ as I wanted this to be easy to mount and last forever. With all of the PS2 to whatever adaptors out there (xbox, gamecube) you should be able to use his controller on whatever as long as you have a good adaptor or worst case rip out hte controller and put in a next gen one. I'll post some wiring diagrams in a bit as well to show the analog to digital circuit used in the mouth controller and the pinouts of the PS2 controller I worked on. Hope this helps... if not just tell me to stop. :-) -Zinfari |
