On the occasion of Bird being ordered to remove its scooters from the streets of San Francisco, JWZ has published the beginnings of a costed teardown of the key components of any you find lying around after they become illegal litter:
We can see from the photo at the top that these scooters have a Particle Electron inside: that's a microcontroller with 1MB RAM, built-in cellular modem and 30 GPIO pins. It's like a $70 value! I haven't seen a breakdown of what other gear is in there, but it's safe to assume that there are two pretty hefty electric motors and a sizable battery. I'll bet you could make a pretty decent robot, or even a drinkbot out of these parts.
I eagerly await reading someone's "Instructable" tutorial on such a project. Maybe you can re-purpose this parasitic, Commons-destroying litter into something fun.
