How to transmit data from an analog multiplexer to an RS232

I am having trouble understanding how to design a circuit that will transmit multiple analog data signals to a computer through one RS232 COM port. The analog data is a simple voltage reading from 12 different LEDs. The LEDs are triggered by relays that are controlled with software from the same com...

LM3886 Schematics + PCB

Hello! Very small PCB based on Yorkville Amps. This circuit diagram Yorkville use in 50w guitar and keyboard amp, active stidio monitor, active PA speakers, small powered mixer... Circuit is simple R5, C5 and D1 make turn on/off delay on mute pin. I made over 80 PCBs, and use PC procesor heatsink fo...
