oh my god, why is this stuff not dead yet? stop talking about "holistic AI education" and burn this down already

I nerdsniped @dimin into helping me out with something and here are the results (a friend in need is a friend indeed!)

did I just say "coilcraft capacitors"? I mean coilcraft transformers 😅
got some PCBs for a small project from @aislerhq
the coilcraft capacitors have < 1 pF interwinding capacitance 👀

after further investigation:
- the 1 mV step remains unexplained, but I suspect ground current issues
- the 100x gain causes the amplifier to slow down by a lot
- the 400 ns comparator delay was caused by the large 32 mV hysteresis I seem to have forgotten about
there are a few things wrong here:
- channel 4's waveform has an unexplained 1 mV step before the slope, theoretically it should be ~300 μV
- channel 2's waveform should be exactly 100x channel 4's waveform (so they should overlap)
- channel 3's waveform should happen sooner (by ~400 ns)
- channel 4's waveform has an unexplained 1 mV step before the slope, theoretically it should be ~300 μV
- channel 2's waveform should be exactly 100x channel 4's waveform (so they should overlap)
- channel 3's waveform should happen sooner (by ~400 ns)
