If you need 5Vdc power... just tap into a power connector from the PC power supply. The 4 wires are +12Vdc -12Vdc +5Vdc and -5Vdc. You can look at a hard drive or cdrom drive and see which wire is which. Thats what I did to connect the coin slot light on my cabinet.
: I would like some advice on adding a spinner to a joystick control.
: I read the Twisty Grip instructions, the pictures are great,
: but they seem incomplete. For example, in the one piece design,
: they mention drilling holes in the washer to mount screws and
: they use an encoder with nut to secure the wire when the encoder
: sleeve was shown at the top of the shaft. Does anyone have an
: exploded view of the twisty grip complete assembly showing the
: stack-up above and below the control panel?
: Also when looking up parts for the Twisty Grip at Digikey (see link below),
: I found a whole section on rotary optical encoders priced between $2.00 and
: $40.00. Since you are basically using the mouse for the optical encoder, could
: you just mount one of these to the panel, add a knob and wire it up, or am I missing
: something really obvious. If this will work, does anyone know which one would be the
: best one to use.
: If that won't work, is anyone selling preassembled spinner controls (other that Happ for
: $110.00 without the interface). There was message on this site, about Wico having one for
: 47.00, but I called them and they said the item was not listed in their system and acted like
: they had never heard of it.
: Finally, everything I have found so far on spinners mentions using a gutted mouse or trackball
: and interfacing to the PS2 mouse or serial port. Is there any way to avoid running another cable
: by running the spinner outputs to the keyboard right or left arrow positions on the keyboard encoder.
: I realize I would still need +5 VDC from somewhere. I would think this would be available through the
: keyboard port. Does anyone know if any of the keyboard encoders supply +5VDC on one of the pin outs?
: (I am ideally trying to run the spinner and the other controls through the keyboard port!)
: TIA,
