Yesterday I had the good fortune to meet an RCI member (never met before)
Who had dozens of RC models lying around.
From Deltas to DLGs.

Then I saw his crossbows (with fibreglass tube)
And his longbows (of PVC pipe)
So powerful that they are no longer in toy or hobby category...
Wow!

And I haven't even mentioned the Didjeridu he made...

And the day before, met a member who's an old friend.
With dozens of RC models and no place to fly,
He built a 3D printer from a kit.
Which he used to make a pillbox for his medicines.
Then built an Arduino based mechanism to flash lights and beep
To remind him of the medicines he has to take from time to time...

Sure having fun, aren't you, Iyer sir?
