Will try to make a fully functional 555 timer out of discrete components for students to use in other test circuits NOT just a diagram, NOT just a board design, but a fully functional circuit to stand in until Autodesk makes a 555 for everyone's component library.

Use a combination of these diagrams and parts lists.

2 1k ohm resistors 2 10k ohm resistors 11 4k7 ohm resistors (4k7 means 4.7k) 11 2n3904 NPN transistors or similar 9 2n3906 PNP transistors or similar
