Vintage Panasonic remote control for some portable cassette and CD players

thingiverse

Panasonic created numerous cassette player models, with the superior ones coming equipped with a wired remote control connected directly to the earphones. These collectible items continue to trade hands on the secondary market, albeit many lack their original remote controls, making it frustrating when some models' sound equalization can only be adjusted via the remote. Similarly, Panasonic portable CD players shared this remote control technology, rendering this project applicable to certain CD player models as well. This project produces the case and buttons for a wired remote control compatible with several common cassette and CD player models. There are two variants of the controller: The 3-button version works on the following models: RQ-X15, RQ-SX15, RQ-SX20, RQ-SX41, RQ-SX52, RQ-SX53, RQ-SX57 The 4-button version operates on the following models: RQ-NX10, RQ-NX60V, RQ-SX30V, RQ-SX35, RQ-SX45, RQ-SX50V, RQ-SX60F, RQ-SX82V. Although untested, this controller should also function on a number of portable CD players: 3-button - SL-S130, SL-S140, SL-S118Z, SL-S138Z, SL-S320, and SL-CT470; 4-button - SL-S230, SL-S650, SL-S651C. It may also work with other models that came equipped with a non-LCD type controller using a standard 4-pole 3.5mm plug. Included are circuit schematics for the two variants. The case is designed to accommodate a pre-drilled circuit board, cut to shape and populated with standard components. The jack for receiving earphones closely resembles Multicomp Pro MJ-2135 or Lumberg 1503-19 in dimensions. The button switches measure 6x6x5mm overall, while the potentiometer is a duplex type measuring 16mm x 2mm. Note: Once assembled, this case cannot be disassembled without sustaining damage; however, it is compact and does not take long to print another one.
