Hello everyone, I bring gifts! Spent the last few nights making this switch box for all my consoles. Scart is expensive so I went with DB9 plugs, old VGA cables and some ebay scart leads (for the plugs). I use a XRGB Framemister, so this may need some additions to make it 100% SCART compatible I made this simple 8:1 selector pcb, based on the CBT3244ADB Each input has its own bus switch that switches RGB, Audio Left and Right and Sync. The PCB is 8cm by 5cm The pcb ended up being designed in such a way that you can stack the output! So I guess you could have as many inputs as you want going to one output haha So using itead I guess you could have a 80:1 RGB switch for under $50 https://www.itead.cc/open-pcb/pcb-prototyping/2layer-green-pcb-5cm-x-10cm-max.html I used 0805 pads for the input select to make routing easier, to switch each input on you have to pull it low. ALL the inputs and single output use 2.45mm 2X4 pin headers, so you can use whatever connectors you wish. I'm going to use DB9 for my inputs and a 8 pin mini din for the output on mine The chips simply require 5V DC, because the switches will just be switching GND adding LEDS would be easy www.youtube.com/slot1gamer Download the gerbers here:
