My build progress

Yeah, I screwed up that one :woman_facepalming: ā€“ and doubly so since I forgot to solder that resistor at first, and when I got to the cap and realized that I had to fit the resistor in there too Iā€™d already trimmed the capacitor legs, so couldnā€™t put the resistor under the cap. Iā€™ve verified that the headers still fit, though, so good enough for this first board :smile:

(thereā€™s only six nine things on the TODO list for revision 2 this far, but admittedly thatā€™s before any serious electrical testing. But it could be worse :smiley:)

EDIT: The exponential converter doesnā€™t work properly. Annoying. But gave me some ideas that might help people debug MS20 output levels.

EDIT II: That was yet another obviously misconfigured opamp. I really need to add ā€œverify that opamp topologies make at least some senseā€ to my PCB design checklist :upside_down_face:
