Control a 70s style jukebox with an RF keychain remote #MusicMonday

NewImage

Thanks to Bobby for sending in his great jukebox project! Check out the tutorial on Instructables.

The volume control knob on many jukeboxes is located in the most inconvenient place possible. It is done purposely to discourage drunken bar patrons from blasting their music resulting in annoyance of their fellow barflys. The standard location for the volume control knob is in the middle of the back of of the jukebox against the wall. 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. Most jukeboxes have an optional remote control on a long wire for the bartender to control the volume. Some models have a rheostat that mounted in a little box with a momentary switch. The remote rheostat controls the volume. Twisting the volume control knob raises or softens the music volume. The momentary switch controls the “Cancel/Reject button”. Pressing this button will eject the current record playing. If the record is scratched of extremely distasteful it can be ejected by pressing this button. The Seeburg SMC 1 Disco does not have such a simple remote control. The remote control uses a motor that attaches to back of volume control rheostat. It is supposed to behave like a hand turning the control knob. They are expensive and look unreliable. The parts are 35 years old. It is difficult enough to keep the jukebox running, without this additional complexity. I thought about the problem for a while, then decided I can twist a knob with an arduino.

Keyfob 4-Button RF Remote Control – 315MHz: This 4-button keyfob remote goes with our three basic 315MHz RF receiver modules. It will work with all of them, sending out one of four commands that match up with the four outputs. Its small and light weight and will work up to 25 feet away depending on line-of-sight and obstructions. Since this is just a transmitter, if you have multiple receivers, it will turn all of them on and off at the same time (there is no sub-addressing) Read more.

Simple RF M4 Receiver – 315MHz Momentary Type: These Simple RF receivers are the easiest way possible to add wireless control, painlessly! There’s no programming, configuring or addressing – simply power the receiver with 5-10VDC and press the buttons on our matching RF keyfob remote. When the A button is pressed, it activates the first pin, when the B button is pressed, it activates the second one, and so forth for all four buttons. There’s no microcontroller required, its just a simple one-to-one link. Read more.
