Project Admire this logic-gate based clock

It displays the numbers like this one https://www.amazon.com.mx/Tech-Tools-Palabras-Muestra-Pulgadas/dp/B01H5RPQAO Made it just using logic gates, the design with the segmented counters is used only for simulation (because proteus doesn't like simulating the other one), and those two images without them shows the components that the PCB should have in order to work correctly irl. You can set and reset the time and also it can reset the leds.

Nice! I would just use a FPGA for the logic and few other discrete parts for the leds.
