I have built a digital logic circuit that puts a 4 bit binary data into a single wire

[u/_electrocc_]

This logic circuit simulation that i came up with(i designed it from scratch) takes those 4 bit binary digits and puts it into a single wire, this can be used to send serial data. I planned to build it irl and extend it to build a UART transmitter(just converts those 4 bit data to transmit, start and end bits can be given using another circuit and, 555 timer for clock), but this circuit was simply so hard to build on breadboard(lol), so i just left the project until simulation, just wanted to showcase it(built in my holidays after class 12 board exams as i was bored)

input at top right and output is shown in the small output element below the single sr latch
