Homemade high-voltage probe not dividing the voltage by proper amount
I have tried to build a homemade high-voltage probe, as commercial ones are too expensive.
Firstly, I connected a 1 MΩ resistor to a ~1.4 V battery which gave an output voltage of ~0.2 V. By using ...

Why am I seeing a signal on a shorted differential probe?
I am chasing the cause of some weird microcontroller resetting behaviour in a prototype robot. As part of the debugging, I decided to look at the stability of the power supply for the MCU.
I soldered ...

Non-zero voltage measured across shorted positive and negative differential probes tied to a single circuit node
If I place the positive and negative probe tips of a differential probe on the same location, and therefore the same node, (such as sharing a test point), I would expect to read a zero voltage.
What ...

My Wien bridge oscillator doesn't work, what could the problem be?
I suspect I am making a probe connection mistake, but couldn't figure it out.
The circuit works fine in LTSpice but I don't get anything in a real experiment.
What might be the problem?
