Monostable 555 timer - 8-bit computer clock - part 2

That is supposed to say on this site

Ben these videos are awesome. I watched the whole series on YouTube some of the videos multiple times when I couldn’t quite remember how certain things work. In one of the final videos you asked for suggestions, so could you build or explain a voltage comparator circuit with basic components, transistors etc... it is one of the only components that I could not understand the inner workings and have not found anything useful online. Also I’d like to contribute a lump sum if possible since I’ve already seen all the videos on YouTube, if you can add that option on this this.
