[Gumstix-users] pulling measurement

[mike w. <mi...@mw...>]

Hello all,

    I am on the last tech hurdle to finishing my robotics project, and I 
figured you are all smart people....

I need to measure the force being pulled on rope...  I've looked at 
load cells and they are just a bit too expensive.  Any ideas?  I need 
the data to interface with my microcontroller or with a PC via USB or 
Serial.

Thanks alot everyone!
