A marimba note being struck while thrown in to the air. Can't remember the mic that was used but it was a condensor mic. This was recorded in my room so unfortunately the signal to ambient noise ratio isn't great. The sound can be used for free (though it would be great to hear about what you do with it). It may not be re-distributed as it is, or as part of a compiled sound library.
This is cheap table fan spinning around and moving from left to right. Recorded from top of the fan controllers with nokia 6. 2. Android phone. No processing, just boosted in audacity.
I designed an educational game where we had a spinning wheel, ala 'wheel of fortune' i created this sound to repeat as the wheel was turning and hitting each element.
