Hi! So I need to build a machine that only works when you smile for a school project. Basically, when a smile is detected a relay turns on the machine until the smile is not detected anymore.
I was wondering if anyone has any advice for me how to achieve this as simply as possible? I would like to mount the device and camera inside the machine and preferably run on battery for an hour or two.
I was looking at mediapipe and a raspberry pi, but then I thought about Edge impulse and was wondering if it is possible/reasonable to do here?
What platform would be good to run it on? Also raspberry pi? or something else?
