Hello
This is my first real circuit built only from schematics. It is for my physics A2 coursework. The circuit operates on monostable 555 IC and is powered by a 9V battery. It is SUPPOSED to display and ESR of a capacitor that i connect to the terminals, on the analogue display. Unfortunately i get no result on the display. I have built 2 circuits: 1 at home and one in classroom - both seem to have a normal current flow through whole circuit (no short circuit) but i get no indication of ESR. I'd be grateful for any help regarding my non-working circuit. I will link an original website as well as pictures of my circuit from classroom. As i said this is my first time so be gentle
(also i do realise that the rightmost resistor is in wrong hole i did change that and still no luck).
Thanks, any help would be appreciated.
Original Schematics Website (it's in czech but really the schematics matters),
