I've been working on a project at school where I had access to a big variety of test equipment. I no longer have access to anything but a basic meter.
I have a circuit that amplifies/filters a signal to light LED's. I took it out of the box to draw a schematic. When I tried to use it again, absolutely nothing happens. At school I would just power it and use the scope to see where the problem is.
I would see if the signal amplified on the output of the first op amp, if yes, see if it is on the output of the filter, etc.
How would I go about diagnosing the problem with out a scope?
