Decoding Frequency-Shift Keying Audio Files for the Sayso Globard LED Sign Matrix
an interesting analysis of these Sayso Globords, LED message displays programmable via light pen, or audio input. As far as I can tell they’re designed by a Canada-based electronics component company (Red Current Technologies), and might be specific to Canadian retailers; I haven’t seen them in the northeast U.S., but that’s not to say they’re not migratory devices.
The audio files used for programming the display are clearly FSK-encoded, but I haven’t quite worked out the relationship between the tones and the display bits.
