William Osman's video where he built a stroboscope, https://www.youtube.com/watch?v=9TiJvN_NIQc. Also we very often find unlabeled motors that we need to find the speed of.
What it does
It uses the camera and dynamic framerates to act as a stroboscope. Traditional stroboscopes use human persistence of vision to measure the speed of cyclical motion, which limits use cases. On the other hand, ours uses a camera, and does not rely on persistence of vision, so it can measure more types of cyclical effects like fluorescent light flashing, for example.
How we built it
Challenges we ran into
The small sensor in the phone cannot take in much light at high shutter speeds. We also had some issues prioritizing certain gestures over others.
Accomplishments that we're proud of
What we learned
Using the camera in iOS, gestures, further explored concepts of shutter speed, and ISO
What's next for Strobr
Make photo quality better, explore possibility of cv so the phone could do more by itself.
