not impossible at this point.
I really hope the capsule isn't fucked, it's the most expensive part and the shipping takes forever too.
But then again in the old circuit it worked, and apart from dropping it on the ground once, and not too hard either, there isn't anything else i did that could break it i think.
At the tranny drain i get 9V (my power supply is 9V)

at opamp + and - i get 6.8V and 6.1V... hmm shouldn't those numbers be the same? from my limited understanding the opamp should balance those inputs to be exactly the same. But while measuring it i noticed i possibly fucked up here,
the opamp is connected with + on top and - on bottom, but actually in the original schematic i followed it's supposed to be the other way around (so the pins 5 and 6 should be the other way around) could that be the problem?
