Hi

Is it possible to use a webcam to count how many jumps I do while skip roping.

And displaying the number live on a screen!

Kind regards Thusgaard

In theory: yes. In practice: only if you have a lot of time on your hands and not a life to live Razz

And lots of money for the cameras and programmers as there no off the shelve app available Rolling Eyes

I think this would be difficult (but not impossible) to do on a computer with images captured by a camera. You could try a kinect (if that is the word) but you'd similarly have quite a programming overhead. Although, as an aside, I'd have a look and see if someone has written a library for counting events that occur in images/a video stream.

I think an arduino for event counting and data export to pc would be a good bet here, with skips detected by the rope breaking the beam of a diode laser targeted at a light dependent resistor or a photodiode.

Yes! I think it's eminently possible.

I think you should check out OpenCV -

And try looking for some similar vids on u-toob.

I'd be interested to see what happens!

Could also use a microphone count the number of times the rope hits the floor but your approach Bruno would be more exact.
