I recently watched Techmoan’s YouTube video on using a PS2 keyboard to title tracks on a MiniDisk player. Cool stuff. I am a fan of the MiniDisk form factor despite it falling out of favour before I really got into it properly.
So Techmoan used a PS2 keyboard to title his tracks. That’s a pretty forward thinking solution from Sony (Well all but that PS2 keyboards are hard to get hold of now), they even thought ahead enough to put it on the front panel.
Now, the tragedy in all this is I own a Sony MDS-JE480 deck, as it goes it’s a entry level deck, but otherwise not too shabby. Except it doesn’t have a PS2 port. So I can’t title with it. Or can i?
Titles can be entered using the original remote control (which I also don’t have). This would tend to be a relatively painful process as you’d have to enter these titles using a T9 keypad but without the intelligent predictive part.
Now, some clever sod has written some code for Arduino, so it behaves as a kind of serial-infrared remote control. And this can be used to enter track names. It would also be a hell of a lot easier than using the T9 keypad. The Hackaday article really does a good job explaining it all, but skimps on the hardware description.
Main steps – take the code from the hackaday page, and save it onto you machine. Choose a suitable digital pin to attach the LED to. I’m using a Uno, so I need to use Pin 9. I use a BC547 Transistor and a IR LED out of a old remote to get going. Simple, but effective. The BC547 sinks or blocks the current through the LED as required. It may also be possible to ditch the BC547 and just go with the LED, but you may run into current constraints on the ATmega328.
