This project is to develop an apparatus to apply torque to sample bones to study their response. Glenn has tentatively picked out the following items:

• Driver ($536): ​https://www.mcmaster.com/6627t62 (​mfgr page)
• Motor ($161): ​https://www.mcmaster.com/6627t55
• Torque cell ($535): ​https://www.omega.com/pptst/TQ301.html

The Driver in principle requires a controller too, as it only has STEP and DIRECTION inputs. McMaster? suggests this one:

• Controller ($473): ​https://www.mcmaster.com/6627t68

Omega lists a strain gauge meter with analog output

• Meter ($375): ​https://www.omega.com/pptst/dp25b.html
  • (DP25B-S-A model for strain gauges with analog output)
