 # micro Stress vs Strain Machine
 
-## Progress 
+## Dedicated uSSM

+ - GT2 5mm 12mm Bore Pulley 28T for 15mm Belt 'A 6A55M028DF1512'
+ - GT2 5mm 12mm Bore Pulley 38T for 15mm Belt 'A 6A55M038NF1512'

+
+End of the line here is (1) to do small-scale material testing, OK. Next step is (2) to automate material search, doing a kind of real-time simplex where function evaluation is testing and DOF are process and recipe parameters. This is a cohesive, realizeable story. 
+
+I would like to know:
+ - evaluation: pick: Stiffness and Tensile Strength? some weighted score from both?
+ - inputs: if we are to pick, say, 3 process parameters (to have 3D search space), what are they? 
+
+## Next Steps
+
+ - fab this thing 
+ - finish waking up new network, new stepper boards / code 
+ - finish hello-world CV on markers 
+ - plot a stress/strain chart 
+ - show high resolution stress / strain measurement w/o high stiffness machine
+ - show machine reference via known material?
+
+## Generalist does uSSM 
 
 To test requisite parts for a small stress and strain machine, I attached some jaws and a load cell to [this 'generalist' machine](https://gitlab.cba.mit.edu/jakeread/mothermother).

-Probably the most interesting point is that Sam and I have decided to try using a webcam and some computer vision to track the position of the speciment endpoints. He's done some prior work, [here](https://gitlab.cba.mit.edu/calischs/subpixel_tracking).

+
+[Alisya did this in FabAcademy](http://archive.fabacademy.org/2017/fablabsantiago/students/356/project.html) and it would probably be a fun piece of kit / example for the NIST Project. Looks pretty simple... and compelling.
