UPDATE:
I figured out the reason that one cable is not working: the usb-c connector I'm using has CC1 and CC2 lines shorted together, so you have to cut one of them off and solder its own resistor. Video update:

TL;DW: cut the connection between CC1 and CC2, then add a separate 5.1k resistor to CC2.

USB-C cables/devices are complicated. This was my attempt to simplify one aspect: how to get 5V from a usb-c cable.
I bought these connectors on AliExpress. Out of the box they only work with USB A to USB C cables, so they require some modifications before you can use a pure USB type C cable with them.
