You know it, I like to make sure people didn't get lazy in the their personal thread and leave out images to later put them in the pic storage area thingy. Also, I love seeing new builds that have something special about them that I have yet to see. Building a cab is badass, but adding auto-rotate screens and random shite to it to make it special keeps me refreshing pages on the forums like a mad man. :applaud: |

When playing solo, I like playing from the center position regardless of the game or screen orientation. It could be triggered by a switch, but really it's just as easy and probably faster to slide it by hand. I probably will add 4/8 way switching, but it won't be by mechanical means. :) The plan was to take a SparkCE optical joystick sensor and rig up a way of changing the sensetivity via command line. http://www.godlikecontrols.com/ It would require being able to control a potentiometer from the PC or switching between 3 different resistors. (least sensetive for 4-way, normal, & super sensetive for shmups) Worst case scenario is that I add a manual 3-way switch somewhere. Unfortunately, I installed my SparkCE's late Thanksgiving night after driving 6 hours and failed to realize that the metal S-brackets I was using were making contact with the underside of the pcb. :'( It fried all the IR LEDs. They still post presses when shining light at the sensors, so I'm hoping that is all that is fried. I'm waiting to hear back from Toodles about a repair. If not, I guess I'll start trying to find the right model IR emitter or just bite the bullet and order another set. :banghead: I'm thinking I might be able to get away with ordering the standard non-adjustable model and just adjusting the voltage to it. I think that's pretty much all the pot in the SparkCE is doing. Might even be able to use an LED Wiz and pulse the power to dim them. Some testing is in order, but I should finish the CP first. I also wonder if doing all this really offers any advantage over using Ultimarc U360s. (the point is moot though because I want to do it just to see it done. :P ) |

Toodles was nice enough to give me part #'s for the IR LEDs that I fried. Installed them and the Spark CEs are alive again. ;D That done, I moved on to tinkering with the sensetivity. One joystick was adjusted until the circular moves in fighting games came easy. The engage distance also turned out to be next to nothing, so I think they'll be acceptable for shmups even if they still have to much throw. The other joystick was set to a reduced sensetivity for 4-way. I wanted to make sure the corners were not being hit. I wanted a visual representation of the joystick on-screen while I was tweaking it. The best solution I came up with was to map it to a virtual analog stick using Headkaze's VJoy: http://www.headsoft.com.au/index.php?category=vjoy Bring up the virtual joystick in windows control panel and you can easily see if the corners are being hit and for how long. Even with the trimpot on the SparkCE turned all the way, it was still possible to get it to register the corner, but just barely. It made a noticeable difference on Donkey Kong. I didn't get stuck at the top or bottom of ladders at all. The circular restrictor felt just fine to me. So now I have an idea of the resistance values I'll need to switch between for the two modes. The plan is to make a circuit that can switch between the two values. It will probably use optoisolators controlled by a Pololu Maestro servo controller (it does LEDs too), triggered by DaOldMan's joychoose. Parts for handling it multiple ways were ordered last night. :D I'm really liking JLF/SparkCE/round restrictor combo. They have LS-56 springs in them, but I may go stiffer. Going to order a selection of springs from Paradise Arcade next time I place an order there. The weather has been crap and it's dark by the time I get home from work. Not getting much done on the actual building front. I did manage to install the cupholder and bondo up the exposed edges over the weekend. Not looking forward into sanding them inside the house. |

Dear lord! You seemed to have solved the cup-holder conundrum :applaud: No more spilling drinks on your control panel....People rejoice! |
