As far as I understand the Hackaday-Link, it is something simple like this:
with an arduino nano giving alarm. If you program the nano to set an output pin and connect it to an alarm port of your printer-controller (e.g.: out of filament) it's easy.
if you are familiar with the printer-firmware, you could even directly connect the encoder to your printer-controller and include the stop code there. (maybe some firmware already has this included?)
The smaller you make the wheel, the faster the pulses are generated, the faster you get to know if the filament is stuck, or ran out.
If you want even faster detection, you could use a small and a big gear to increase rotation-speed of the encoder.
This encoders already give you direction information.
So I do not see any need for new design - everything already here :-)
(My last clogging was over a year ago - better solve the problems instead of getting to know when it ocures - but just my opinnion)
