Sounds like the movement of those old VCR dials that you held for fast forward and reverse. Maybe you could hack a VCR dial. |

I've been looking. They're used in all sorts of applications, usually related to audio (of course). But I suspect due to their limited appeal outside of such a niche market, they're generally not very common for a reasonable price. I did look at "pistol grip" controllers for RC cars. I believe they're called Return-to-center potentiometers. Drop in replacements run for as much as a brand new high-end transmitter (or more) but I spotted super cheap RC controllers like the FS-GT2 (runs for about $20-$35) that might have a usable knobs but I can't really tell if they're true analog pots or just those Wal*Mart special Full Left/Full Right steering. The hobby guys will know what I'm talking about. I intend to figure out which hobby shops are still open so I can see one in person (assuming they would carry it). Rocker switches on the other hand seem to be a little more common and I've found them listed at digikey, mouser and they're likely at newark (Google them) as well. At Digikey, they're listed as mom-off-mom switches. Depending on the desired profile (amp rating can be ignored if they're simply going to be inputs for an iPac) you can grab a switch for around $1.13 for a single. I often find them in the grab bins at local swap meets (though even those have disappeared for me :( ) YMHML. --- Quote from: Jammin0 on October 21, 2011, 01:51:29 am ---Sounds like the movement of those old VCR dials that you held for fast forward and reverse.

The knob may "feel" heavy, but go behind the scenes and it's just a rod (or some other similar setup) smacking against two micro switches... if you're lucky. The mechanics behind the knob is usually integrated into the case itself. Remove the assembly from the case and... well... you've got nothing worth using. Your best bet is to find an older style VCR or more expensive model that supports pseudo-jog. But even then it's hit and miss (for me at least). I've come across everything from YPXT switches to pots to encoders of varying degrees of salvageability. I don't do VCR repair but I do salvage parts from them on trash day and I'd say that unless you have oodles of VCR's to dig through, it's just not worth the time to actively look for a VCR that would work for you. Now that VCR head... that's a whole other matter. Not saying you shouldn't look at VCR's as an option. I would. But if you don't have a source for VCR's, don't bother expending too much effort to find them. They're even getting scarce on trash day. |

Ok, now what I want, exists... :) It took all of about 15 minutes to put this together, and it works exactly as I originally wanted. All it cost was 2 microswitches, I can live with that. :) If anyone is interested: I have a 4mm mdf panel, 10cm x 10cm A pine block, ~1cm by 1.5cm by 3cm 6cm bolt & 2 nuts Volume Control knob (that knob is just one I had lying around) Drill hole through pine, put the bolt through it and tighten it up with a nut. Drill hole through 4mm panel, put bolt with the pine through it Mark the edges of the pine on the panel, then mount the micro switches in the correct positions. (When the switch is not being used the pine should just be touching each button.) Mount panel on inside of cabinet, (the 4 screws in the corners) Drill hole through cabinet, then push the bolt through. On the front of the cabinet, tighten the bolt up so there is almost no play, just enough that you can wiggle the screw slightly but not pull it back & forth. Stick a knob on it, hook the buttins into i-pac or other controller and set them buttons up as volume controls. Easy peasy and still looks pretty! (to me anyway :P) |

I just used a dual 100k audio taper pot in series with the audio output from the board and mounted it inside the coin door. Don't get much easier than that.... http://www.flickr.com/photos/62937081@N00/6283088858/# |

I just put 2 led arcade buttons on my cab between the speakers and wired them up to the 2.1 Logitech speaker system. One red, one green. My guests have had no issues with figuring that out. Red turns volume down, green up. Although I'm probably the only one who knows that pressing them both turns them on/off. As an added bonus, the speakers had a power led that also happened to be 5v, so it drives the leds on the buttons. |
