Hand dynamometer-part 2

I carved handles out of wood and mounted the strain sensors in it.

Gripping it as hard as I can. Was interesting to see grip strength fail and then increase again when I redoubled my efforts.

Seems to be a working, if low quality dynamometer. If I was to redo this I would build more around the grip and possible use different strain sensors. I might measure the effects of irraditation (tensing other muscles in this context) on grip strength later.
