Hello, I want to make a DAC on my own and couldn't find any materials to help me. Could anyone point me to something that can explain to me how to make a DAC and all the components? Thank you!

That is a rather open-ended question. There are so many different DAC topologies to choose from depending on your requirements. Of course the only DACs anyone does "from scratch" these days are primitive R2R ladder DACs (because they are so trivial). Most people use a DAC chip - see their application notes for auxiliary components. Of course you can go really fancy and use FPLAs etc., but you'd better know what you are doing and the benefits are questionable.
