JMP-rope, the programmable jump rope

Mix sport, technology and art and you get the perfect project.

I really enjoy art even though I am not much of an artist myself, I am definitely a technologist (more of a researcher of technology than a user TBH), and I've become a sports person too in the latest years, in particular I discovered how jumping rope can be a fun way to do cardio, way funnier than playing hamster on the treadmill; and each time I was jumping rope I started thinking about a tech project involving a jump rope.

Some relative of mine forgot the password to access their e-mail account, but they were still remembering the pattern they used to pick it up, and that pattern could be easily represented by a regular expression.

A blood pressure meter with a USB port happened to land into my hands, only Windows was supported for downloading data to a PC, and I wanted to see how the device interacted with the software and try to “free” it so that it could be used elsewhere.
