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

Hi, I am an electronic engineer with a good talent in electronics. I can do this project. I have a good knowledge in all altium, arcad, eagle. I already have an idea to make this.
Hi I am a power electronics engineer and having good industrial experience in product design development as well as timer circuit design for the necessary digital circuits. So I can help you to finish the work.
I simulated circuit using 4 - transistors 4 - diode 11 - resistors 3 - capacitors. For the scheme to 2 - Power (5v, [url removed, login to view]) or divider resistors. In reference oscillograms: [url removed, login to view]
I can design that. with only capacitors, resisters and with transistors.. but I would like to say to you.. easiest way is NE555. i will give you schematic capture. thank you. best regards.
