Just getting back from ROSCon in Kyoto and seeing your response. Thank you so much for the detailed pointers. I’m learning a lot from them.
I’ll make some fixes and upload them here in the near future: Hopefully someone else out there will be able to learn this thread in the future 
Edit: Regarding the capacitors, I stole that design choice from OP in this thread, but I don’t have a good justification for using those capacitor values. Maybe I misinterpreted what he was going for there, but from videos like this I’ve heard that using different values will help account for interference of different frequencies.
