Hey Ryuta,
Yes, we'd thought about PIR's. My understanding, and I'd be happy to be proved wrong, is that they are either 'on' or 'off', motion or no-motion.
And this case what we'd really like is to be able to detect motion but also depth (3d) so we can measure whether something is moving towards and away from the chimes with a proportional representation of force. Then ideally lateral movement too so, say, someone waves their arm from side to side that that could also be measured.
Tricky & challenging on such a lightweight machine, particularly with no GEM, but I guess that's also part of the fun:)
Many thanks for your suggestion though.
All the best,
Julian
Maybe check out these things:

It gives you a 4X4 pixel temperature image, and unlike the PIR sensor, it can detect motionless warm objects.

Hey Martin,
Wow, like that a lot. Needs some more digging into but looks very promising.
Have you tried one yet?
Will get one and report back if not.
Next weeks too crazy but will get into it the week after.
Top tip, cheers.
Julian
