All-In-One DB9
Posted: 18 Sep 2018, 13:38
I like the Gigatron esthetics so much, that I hanged it on my wall! Unfortunately that means if I want to use it, I need to plug at least 4 cables (power, audio, vga and controler), which isn't really nice hanging around.
Since the DB9 connector still has 4 empty pins, and power and H and V sync are already there, the goal is to put all remaining signals on it.
The mod is simple (a few short cables behind the PCB from Line_out and RGB to the DB9) and reversible.
This enables to use a single DB9 extension cable to transmit everything to a small breadboard box including the Arduino Nano, and the VGA, Controler and audio ouputs. That would be neat and clean to get a simple extension box with a single db9 wire to the Gigatron.
Any thoughts?
