Analogue/discrete UART reciever

I built a discrete UART reciever using transistors, resistors and LEDs for my school project. It contains ZERO ICs. And it works. :)

Quantity		Component name
416	×	Transistors Type i used: BC547C
604	×	Resistors Mostly 100K, 10K and 560 Ohm
134	×	LEDs to enlighten the world
81	×	PCBs 12 different designs: from NAND GATE PCBs to Button boards
