ROWE AMI CD JUKEBOX STATIC ON LEFT CHANNEL DRIVER
Motor/Stepper Driver ( Adafruit #1438 $19.95).Hopefully this guide may help keep a few jukes alive in their semi original state a little longer.
Modifications to an old juke can be reversed without any significant changes to the jukebox. Although this modification was done to a Seeburg SMC 1 Disco,it can be adapted to many other brands and models. The volume can still be controlled manually, but it requires opening the cabinet and twisting the control knob. The RF module can be tucked away in the back or side of the jukebox cabinet. IR would require putting a receiver somewhere where it can see a light signal. Raido Frequency (RF) was chosen over Infra Red (IR) because it requires no modifications to the cabinet. The stepper motor is a bipolar four wire 200 step 12V stepper. The motor is controlled by a shield which uses 74HC Bridge. The arduino processor is a good choice to control small motors and interface with humans. I thought about the problem for a while, then decided I can twist a knob with an arduino. It is difficult enough to keep the jukebox running, without this additional complexity. It is supposed to behave like a hand turning the control knob. The remote control uses a motor that attaches to back of volume control rheostat. The Seeburg SMC 1 Disco does not have such a simple remote control. If the record is scratched of extremely distasteful it can be ejected by pressing this button. Pressing this button will eject the current record playing. The momentary switch controls the "Cancel/Reject button".
Twisting the volume control knob raises or softens the music volume. Some models have a rheostat that mounted in a little box with a momentary switch. Most jukeboxes have an optional remote control on a long wire for the bartender to control the volume. To change the volume of a jukebox an intoxicated listener must pull the jukebox away from the wall, grope around for the knob, twist it, then move the jukebox back to its original position, without anybody noticing this activity. The standard location for the volume control knob is in the middle of the back of of the jukebox against the wall. It is done purposely to discourage drunken bar patrons from blasting their music resulting in annoyance of their fellow barflys. The volume control knob on many jukeboxes is located in the most inconvenient place possible.
