Project Description


I would need the schematics and the list of components to reproduce a timer (see attached document).

I do NOT need a prototype but just the schematics.

This has to be done with only transistors, resistors and capacitors. No timer NE555 or equivalent components.

The reason is: I need the cheapest timer possible
