Body Fat Analyser
Have just been looking at buying some body fat analyser scales, and they are so expensive! Â£40 for what is essentially a few electronic components and a lookup table seems ridiculous.
I think they use an electric pulse and then something to do with how the fat/water whatever resonates or something. As you see I don't have much to go on. Can anyone shed some light on how they measure these things and maybe even post an Instructable. Much appreciated.
